More Profound Things: The Non-Living

There are many things and concepts within the collective worldviews of humanity that are considered pretty mundane. However, there’s certainly a collection of things and ideas which rise to the top in profoundness when compared and contrasted with the ordinary everyday routine. These are the sorts of profound things and concepts which keep you awake at night, pondering the Big Issues. No two people will come up with identical lists. Without further ado, here are some more of mine. 

* Matter: Matter is profoundly just frozen energy. Matter and energy are not different things but the same thing, as Einstein theoretically proposed and the Manhattan Project demonstrated. Even burning a match turns some matter into energy; a nuclear reaction even more so; and the ultimate – matter-antimatter annihilation. Energy is probably more fundamental than matter since it’s much easier to turn matter into energy than energy into matter, at least on the macro scale.  

* Electrons in the Twilight Zone: When an electron rises or falls from one atomic energy level to another, when in-between levels the electron is in a profound limbo, in Never-Never-Land, in The Twilight Zone, in another dimension for all we know. It just can’t be anywhere that’s locatable in-between for if it was – in-between that is – it would possess an in-between energy state that it is not allowed to have.

* Delayed Double Slit Experiment & Time Travel: We all know about the infamous Double Slit experiment, which in one variation allows the experimenter to peek and thus see if one particle (photon, electron, etc.) can actually pass through two slits at the same time, which is what happens when the experimenter turns her back. Of course the particle will only go through one slit or the other if there is a Peeping-Tomboy around. But what if someone, human or independent observation device, peeks, but only after the particle has already passed through presumably but absurdly both slits? That shouldn’t affect the outcome since it’s now too little to late for the particle to change its mind. But again, irregardless, the normal particle-that-passes-through-both-slits that results in an eventual wave interference pattern, that pattern disappears even after the peeking is done, even after the particle has passed through both slits. The one very nasty implication is that the particle travels back in time to just before or when it was emitted so as to now make the correct choice (pass through one and only one slit) to correlate what it does with what is detected - A profound conclusion indeed.  

* Pane in the Glass:  You have one light source. You have one normal everyday clear and clean pane of glass. Some of the light (photons) from the light source will pass clear through the clear glass, but some of those identical photons will reflect off the clear surface of the pane of glass. One set of circumstances yields two differing but simultaneous outcomes. That violates cause-and-effect. One could almost say photons exhibit a restricted form of ‘free will’. That’s crazy, that’s profound, but it happens as you can verify for yourself. 

* Electric Charge: The electric charge of the proton is exactly equal and opposite to the electric charge of the electron, despite the proton being nearly 2000 times more massive. There’s no set in concrete theoretical reason why this should be so. This could be considered a profound example of ‘fine tuning’ that makes our cosmos a ‘Goldilocks’ (bio-friendly) Universe.

* Matter & Antimatter: Theory predicts there should be equal amounts of matter and antimatter in the Universe. Observation shows that there is a massive predominance of matter over antimatter. Something is screwy somewhere. Anytime something is screwy somewhere, profoundness is not far behind.

* Mother Nature: Why are there laws of Nature? Why is Nature organised? Why is Nature creative? Why is Nature self-ordering? One could imagine a universe where there was nothing but an endless cosmic ‘soup’ of quarks and electrons and neutrinos and photons and there were no interactions between them. All was just chaos and there was no mathematics, hence no physics, hence no chemistry, hence no biology. That the in-the-beginning chaotic state profoundly evolved into laws and organization and creativity and the self-ordering of things, instead of remaining forever and a day in a chaotic state, gave rise to Goldilocks.  

* Goldilocks: Why is the cosmos bio-friendly? Well the Universe, or at least our Universe, has to be bio-friendly otherwise we wouldn’t be here to wonder why our Universe was, well, bio-friendly. But why is it so, when one can envision all sorts of universes where the laws, relationships and principles of physics could be just ever so slightly differently that would make your existence, and all other life-as-we-know-it life forms, impossible. That makes our bio-friendly Universe a rather profound Universe.

* Time and Time Again: What is time? We all know what time is, at least until we’re required to actually have to explain it. It’s pretty profound that we have such trouble coming to terms with something so fundamental in our lives; a concept that has been philosophically and scientifically been bounced around like a ping-pong ball since the beginnings of recorded history and probably even before that.

* Grandma, Ma and Baby Make Three: There are three generations of particles. There are three generations of quarks; three generations of electrons; three generations of neutrinos. That’s profound because there’s absolutely no theoretical reason why that should be, especially seeing as how only one generation plays any sort of substantial role in life, the Universe and everything, including those bits and pieces that make you, you.

* Spooky Action at a Distance: It’s not too difficult to imagine two entangled objects or concepts such that if you uncover the properties of one, you immediately know the properties of the other. If you know that Jane goes shopping on Fridays, and only on Fridays, and you see Jane at the supermarket, you also immediately know that it is Friday! Jane and Fridays are entangled. But things get spooky when two objects are entangled but their properties are only statistical probabilities. The vacuum energy might spontaneously produce two particles, one matter, and the other antimatter. Say they separate and eventually are light years apart. You track down one particle and it’s a 50/50 chance that it’s matter, or antimatter. Both are actually in a superposition of state, both particles equally matter and antimatter at the same time until such time as you observe the properties of one (or the other), then the collective probabilistic wave-function of the two particles collapses down into an either/or state. Say the particle you tracked down then observed collapses into a matter particle. You then immediately know that the other particle light years away is an antimatter particle. Somehow the particle you observed communicated to its entangled partner that the gig was up – instantaneously even though it was light years away. And of course you acquired the knowledge about the status of the unobserved particle instantaneously even though it was light years away. So profound was this scenario that Einstein finally rejected the whole concept of quantum mechanics being probabilistic, calling this “spooky action at a distance”. 

* Impressive Space! If you remove all the empty space within an atom, and do that for each and every atom that’s part and parcel of each and human being on the planet, one could in theory fit the entirety of the human race into a volume the size of a sugar cube. But that’s just a baby step towards a theoretical singularity and since the constituents are now already in direct contact (no space, remember), so what’s left to compress. Can an electron be squeezed down and further than its normal volume?

The Return of the Hidden Variable

There are many anomalies from the macro-world that can be ‘explained’ by resorting to a Simulated [Virtual Reality] Universe scenario, from statues that walk (on Easter Island according to the natives) to the concepts of an afterlife to those feelings of déjà vu to recollections of previous lives to crop ‘circles’ to ghosts, and so on and so forth. However, most of these anomalies can be classified as belonging to the paranormal or as a pseudoscience and dismissed. Not so easily dismissed are anomalies from hardcore particle (quantum) physics, the most experimentally verified science every known and responsible in gismos and gadgets for over one-third of the world’s economy.

The key to reality in general, including yours in particular, lies in the basics (i.e. – the Standard Model of Particle [Quantum] Physics) and how it builds from the ground up. That reality includes those anomalies and how they can be explained. It’s time to think the unthinkable, so here are a few more reasons why you might wish to consider our Universe to be pre-programmed virtual reality, where heaven knows, anything goes!

Further examples of simulation arguments if any more are necessary.       

* There’s the Pauli Exclusion Principle which notes that no two electrons can occupy the same ‘orbit’ if they have identical quantum numbers or quantum properties. Of course all electrons have the same mass and the same electric charge and the same energy (if they are in the same ‘orbit’) and if in the same ‘orbit’ the same angular momentum and orientation. Pauli came up with another property however that can differentiate between two electrons – ‘spin’. So if there is an electron in ‘orbit’ with one value of ‘spin’ and another electron with the same value of ‘spin’ tries to enter that ‘orbit’ it won’t be able to. If the electron has the opposite ‘spin’ however, then it’s allowed to join in that ‘orbit’. The question is, how does one electron ‘know’ or ‘sense’ what the ‘spin’ of a fellow electron is. That they apparently do is not in question, but it’s damn odd. Take two basketballs and place them close to each other. Spin one clockwise and the other counterclockwise. Neither basketball gives a royal stuff about what the other is doing!  

* Why are all the fundamental particles identical to each of their own kind? Aren’t all up-quarks the same? Aren’t all electron-neutrinos the same? In the macro world no two ‘identical’ products, inanimate or animate, are actually identical down to the Nth detail – not even identical twins. But in the micro world that’s not the case. All photons are identical, even when they have differing energy levels. All heavy hydrogen atoms are identical, ditto so are all those up-quarks or tau neutrinos. Why are all electrons identical? Why this should be so is not readily apparent from first principles on up the line. However, it’s easy to software code any particle, and whenever that code appears, you have an identical particle appear. 


* If something should be but isn’t (say equal amounts of matter and antimatter); or if something is and shouldn’t be (like entanglement’s spooky action at a distance), either is suggestive of artificial manipulation.

* The acceleration of the universe (Dark Energy) and Dark Matter are just the result of the Supreme Programmer not paying enough attention to the finer details when programming the software that serves as the cosmic background wallpaper. It makes sense to skimp on the bits and bytes when it comes to the background wallpaper, but that skimping can backfire.

* If I understand the standard model of cosmology, that Big Bang event, implies that first there was nothing; then there was something. That means the Big Bang event created both matter and energy out of less than thin air. That’s a free lunch. Fortunately, software has a starting point thus explaining the cosmic philosophy of some cosmologists that do indeed claim that first there was nothing; then there was something.

* That Big Bang event also created both time and space out of less than thin air. The day I see a cosmologist replicate that point of view by creating time and space in front of her professional peers (as well as a TV audience), I’ll change my tune. Meantime, IMHO it’s all bovine fertilizer, or software. 

* Apparently the density of Dark Energy remains constant while the volume of the Universe expands. That’s something from nothing. That’s also a free lunch. So how can Dark Energy create more space thus forcing space to expand and the resulting expanding space creating more Dark Energy since Dark Energy is an intrinsic property of space in an endless free lunch loop?

* Apparently, when faced with an energy barrier, particles that lack sufficient energy to surmount the barrier in classical physics, can ‘tunnel’ past the barrier and come out the other side. Now the upshot of that is that this tunneling happens instantaneously. The particle is on the left hand side of the barrier then immediately tunnels and appears on the right hand side of the barrier – instantaneously. Now quantum tunneling implies a velocity faster than the speed of light, which if true would have Einstein spitting chips. Something is screwy somewhere.

* When an electron rises or falls from one energy level to another, when in-between the electron is in limbo, in Never-Never-Land, in The Twilight Zone, in another dimension for all we know. It just can’t be anywhere that’s locatable in-between for if it was – in-between that is – it would possess an in-between energy state that it is not allowed to have. How does an electron vanish from the cosmos or go into a state of non-existence when quantum jumping from one energy state to another?

* Traditional wave-particle duality is according to one interpretation a complementary but either/or phenomenon. Sometimes light/particle experiments show results that prove a pure 100% wave phenomena is responsible; sometimes however other light/particle experiments show results that prove a pure 100% particles phenomena is the only possible interpretation. I’ve also oft seen it described that at point of origin and at the point of detection, you observe a particle. In-between emission and detection it’s a wave. That doesn’t make a great deal of sense unless there is a higher power (a Supreme Programmer) pulling the strings – or programming the program.

* Symmetry holds in 11 out of 12 cases – four forces (electromagnetism, gravity, and the strong and the weak nuclear forces) times three symmetry operations (time, charge and parity) with only the parity of the weak force being the odd one out. There’s something screwy somewhere!

* Entanglement (Spooky action at a distance): Pick and remove a card from a standard deck. Don’t look at it. Bury it in a time capsule. Send the rest of the unobserved deck of 51 cards via rocket ship off to the Andromeda Galaxy. Leave instructions. Generations upon generations later, with the deck of 51 safely in the Great Galaxy of Andromeda, you’re great, great, great (add lots more greats) grand-person can dig up and look at lone card in the time capsule. Say it is the Ace of Diamonds. You do not now need to observe the rest of the original deck in Andromeda to know 1) it contains 51 cards, and 2) that it is missing the Ace of Diamonds! That’s entanglement. And entanglement is something that Einstein called ‘spooky action at a distance’ because you can come by information/knowledge instantaneously – faster than the speed of light. Thus, Einstein was not amused!

* Though bordering on the fringe, some bona-fide astronomers strongly suggest from actual observation that the extreme large-scale structure of the cosmos exhibits a fractal pattern (and there is some extensive literature on the subject). To me however, fractals are primarily a mathematical construction; the product of a mathematical mind, and as such, if there is a fractal cosmos, that’s very strong evidence for a Supreme Programmer. 

It’s just about time here to cite Arthur C. Clarke’s Third Law, which notes that “any sufficiently advanced technology (i.e. – a Supreme Programmer, for example) is indistinguishable from [quantum physics] magic”.

Quantum Physics and Virtual Reality: Part One

Most physicists don’t have much of a philosophical streak and they don’t tend to ask what they study all means. Philosophizing doesn’t pay their mortgage. Physics works, so they just go with the flow; they just shut up and calculate. Most philosophers on the other hand don’t usually have the technical education and background to wax lyrical and come to terms with modern physics. Whether physicists or philosophers, they don’t tend to advertise themselves too far out of their establishment’s standard model box. It’s not usually considered a wise career move, especially if you’re on the academic road upwards and tenure. As for myself, I have no academic career to damage or destroy, so I’m going to combine physics and philosophy and think way, way, way outside of the standard model box. It’s going to be quantum (particle) physics ‘explained’ by appeal to the Simulated (Virtual reality) Universe scenario. If I’m right, the Nobel Prize committee knows where to find me! 

There are many anomalies from the macro-world that can be ‘explained’ by resorting to a Simulated [Virtual Reality] Universe scenario, from statues that walk (Easter Island) to the concepts of an afterlife to those feelings of déjà vu to recollections of previous lives to crop ‘circles’ to ghosts, and so on and so forth. However, most of these anomalies can be classified as belonging to the paranormal or as a pseudoscience and dismissed. Not so easily dismissed are anomalies from hardcore particle (quantum) physics, the most experimentally verified science every known and responsible in gismos and gadgets for over one-third of the world’s economy. Despite all the runs on the board, points of view on the subject of Quantum Mechanics tend to be along the lines of…

Albert Einstein: God does not throw dice.

Niels Bohr: Anyone who is not shocked by the [quantum] theory hasn’t understood it.

Richard Feynman: Nobody understands quantum physics.

And that’s comments by noted quantum physicists.

However, the key to reality* in general, including yours in particular, lies in the basics (i.e. – the Standard Model of Particle [Quantum] Physics) and how it builds from the ground up. That reality includes those anomalies and how they can be explained. It’s time to think the unthinkable!

# CAUSALITY

You tend to associate lack of causality, on the macro scale, with free will. What you decide to have for dinner tonight has no prior cause, just your spur-of-the-moment whim. It’s all free will and free will alone, pure and simple.

However, on the micro scale of fields and forces and particles, you often find they also do whatever they damn well please – no causality need apply. A perfect example is radioactivity. There’s no apparent cause why one unstable nucleus goes poof and an identical clone living next door doesn’t. In fact if something like radioactivity happens for no apparent reason at all, yet that happening follows one precise mathematical relationship (one out of numerous theoretical possibilities) then that surely implies some sort of intelligent manipulation behind the scenes. The Virtual Reality writing is on the wall for all to see.

Either you have to accept that the fields, forces and particles that collectively make up the Standard Model of Particle (nee Quantum) Physics have free will and thus are somehow ‘alive’ and ‘animated’ in some sense (although their free will comes with some restrictions just like your free will comes with restrictions – you can’t flap your arms and fly or hold your breath underwater for three straight hours), OR  else it is all programming software which implies an intelligence (a Supreme Programmer**) somewhere on up the line.

# THE PARTICLE THAT WAVES

Traditional wave-particle duality is according to one interpretation a complementary but either/or phenomenon. Sometimes light/particle experiments show results that prove a pure 100% wave phenomena is responsible; sometimes however other light/particle experiments show results that prove a pure 100% particles phenomena is the only possible interpretation. That doesn’t make a great deal of sense unless there is a higher power (a Supreme Programmer) pulling the strings – or programming the program.

# DOUBLE SLIT EXPERIMENTS

The late Nobel Prize winning quantum physicist, Richard Feynman, thought the Double Slit Experiment (and variations on the theme) was the heart and soul behind the anomaly that is Quantum Physics. It was the ultimate anomaly in a sea of anomalies that could not, in any shape, manner or form, be explained by any sort of, or resort to, classical physics available in the observable Universe. 

1 - If photons, electrons, Buckminsterfullerene molecules (Bucky-balls), etc. are fired in rapid succession at a single slit, with a detector (like say photographic film or a TV screen) behind the slit, then a quasi-blob of impacts are detected. Particles rule, okay!

2 - If photons, electrons, Bucky-balls, etc. are fired in rapid succession at a double slit, with a detector behind the dual slits, then a classic wave interference (constructive and destructive interference) pattern emerges. Waves rule, okay!

3 - If photons, electrons, Bucky-balls, etc. are fired one at a time, at a single slit, such that one photon, etc. completes the journey before the next one is fired off, again with a detector behind the slit, then a quasi-blob of impacts are ultimately detected. Particles rule, okay!

4 - If photons, electrons, Bucky-balls, etc. are fired one at a time at a double slit, such that one photon, etc. completes the journey before the next one is fired off, again with a detector behind the slits, then ultimately after enough firings, a classic wave interference (constructive and destructive) pattern emerges. Waves! However, that implies one photon, electron, Bucky-ball, etc. somehow manages to go through both slits at the same time and thus interferes with itself. That’s absurd. But you ain’t seen anything yet!

4A - The above assumes nobody (human observer or independent measuring device) is peeking and taking the slightest notice of what’s going on – the non-observing nobodies are just looking at the pattern on the detector screen after the fact; after the experiment has concluded. 

4B - However, if someone, human observer or independent measuring device, is peeking and taking absolute and total notice of what’s going on, and determining at the precise time of passage which of the two slits the lone photon, etc. is actually going through (on the grounds that one entity cannot pass through two doors at the same time) then the wave interference pattern doesn’t eventuate and you get a quasi-blob of particle hits on the detector behind each of the two slits. Somehow the photon, etc. is somehow ‘aware’ that it is being observed and changes it’s self-interfering behavior accordingly – keeping in mind that the very act of observing before-the-fact unobserved properties of a photon, etc. alters those properties after-the-fact, since you can’t observe something without mucking around with it.  

4C - What if someone, human observer or independent measuring device, peeks, but only after the photon, etc. has already passed through presumably, but absurdly, both slits and self-interfered with itself? That shouldn’t affect the ultimate wave outcome since it’s now too little to late for the photon, etc. to change its mind. Or so you would think. But again, irregardless, the wave interference pattern disappears even after the peeking is done after the photon, etc. has passed through both slits and self-interfered. The one very nasty and anomalous implication is that the photon, etc. has traveled back in time to just before, or when it was, initially emitted so as to now make the ‘correct’ choice and thus will pass through one and only one slit to correlate what it actually does with what is actually detected. 

5 - Summary: If you turn your back and don’t peek, and there’s a double slit available, the detector screen, and therefore you, will detect a wave pattern because the photon, etc. will pass through both slits and self-interfere.

If you don’t turn your back away from the action, but do a peeping-Tom act, double slit notwithstanding, the detector screen and therefore you will detect a particle (quasi-blob) pattern behind each slit.

The two very disturbing facets are that a photon, etc. displays awareness, and free will, as well as exhibiting the ability to travel backwards in time. Photons, etc. not only know before-the-fact whether or not both slits are open (two open slits equals wave behavior); or that one or the other slit is open (either/or equals particle behavior), but also whether or not someone is peeking. If both holes (slits) are open and nobody is peeking we end up having wave interference behavior; if someone is peeking even if both holes (slits) are open, we get particle quasi-blob behavior. That means the photons, etc. know (how is that possible?) and adjust and exercise their free will (how is that possible?) accordingly.

6 – Conclusion: Now either you’ve got to believe we exist in The Twilight Zone #One where denizens of the micro world have an awareness of their surroundings and possess some degree of free will to react to and within those surroundings, OR you believe we live in The Twilight Zone #Two where said denizens of the micro world are programmed by higher authority** to behave in the way we see and measure them behave.

# MISSING IN ACTION

An electron can have this amount of energy corresponding to this ‘orbit’ (around an atomic nucleus) or that energy level corresponding to a different ‘orbit’ or this other energy level corresponding to a third possible ‘orbit’, etc. but not any energy level (and thus ‘orbit’) in-between (since energy comes in single indivisible quantum packets). Energy thus is a discontinuous phenomenon; just like you can have coins in multiples of five cents (I’m talking Australia here) like five cents, ten cents, fifteen cents, etc. You cannot have a coinage value of seven cents or of nine-point-three cents.

Here’s the rub. When an electron gains or loses energy, it rises or drops it’s ‘orbit’. But where the hell is it when it is rising, or falling between allowable ‘orbits’? Is it in The Twilight Zone or in another dimension or in Wonderland keeping Alice company? Being in-between allowable ‘orbits’ equates to having a forbidden energy level that would correspond to that in-between state. It would be like having a six, then seven, then eight, and then a nine cent coin as you increased the value of your pocket change from five cents to ten cents.

A similar situation could be had for the anomaly known as quantum tunneling. A particle is here on one side of a barrier, then it is there on the other side of the barrier – instantaneously – never to be found in-between.

Of course virtual reality software could easily have our electron disappear and reappear as it quantum jumped from one allowable ‘orbit’ to another allowable ‘orbit’ or as it tunneled over, around or through the barrier.

*It is impossible to know the absolute really real nature of reality since we cannot know the properties of the micro world without measuring/observing them and the act of measuring/observing affects, even distorts, those properties. But, the measuring device is unbiased and independent measurements yield identical results so the disturbances, if any, are at least consistent. Further, theoretical predictions about the properties and reality of potential fundamental particles have all been realized. The predictions that there had to be neutrinos, antimatter, quarks, the particles that convey the weak nuclear force, even the Higgs Boson have all come to pass, so really real reality can’t differ all that much from what we observe and measure. 

**Not by any means of necessity a deity! A real deity wouldn’t stuff things up and give us a Universe that has all the hallmarks that enable me to say that something is screwy somewhere!

To be continued…

Even More Random Thoughts In Physics

Sometimes you have a new thought, an idea, or eureka moment, but it’s not gutsy enough to expand into a reasonable length article or essay. So, here’s yet another potpourri of thoughts dealing with physics and related too good not to record, but with not enough meat available to flesh out. 

oooooOOOOOooooo

* In reviewing several of my essays I’ve noted that I’ve occasionally said that there is just the one physics, yet I’ve often said for the record that quantum physics and classical physics (General Relativity) are incompatible and forever will be. In other words, there’s no quantum gravity and no Theory of Everything (TOE). Is this in conflict? No. There is the one physics even though you’d be hard pressed to unify thermodynamics with levers, inclined planes and pullies.

oooooOOOOOooooo

* Universal Parameters: You cannot determine from first principles what the properties of the Universe, or the fundamental particles that make up the Universe, are. They apparently can have free range. A proton is 2000 times more massive than an electron, but you can’t calculate that from the theoretical laws, principles and relationships of physics. It’s only determined experimentally. There doesn’t seem to be any reason why the proton couldn’t have been 0.2, 2, 20, 200 or 20,000 times the mass of an electron. The same applies to the relative forces. The theoretical laws, principles and relationships of physics do not require an opposite yet of equal value charge between the negative electron and the positive proton. Presumably the value of each could have been as far apart as their masses – that is a proton could have been 2000 times as positive as the electron is negative. Why not? There’s no reason why not apart from the fact that the Universe as we know it wouldn’t work, but then we wouldn’t be here to worry about that or what might have been. 

oooooOOOOOooooo

* We’re all taught in high school the above, that the electric charge of an electron is equal and opposite to that of a proton. The ‘why’ of the relationship is never explained in any shape, manner or form. I’ve never seen an explanation given in any popular particle or quantum physics book. Now either the explanation is so bloody obvious authors don’t feel the need to explain the ‘why’ of the matter and insult the reader’s intelligence, or else the ‘why’ is in the way, way, way too hard basket and authors avoid the question and the issue to avoid appearing ignorant about so fundamental a fact.

oooooOOOOOooooo

* Black Holes would make excellent, in fact perfect, thermos (vacuum) flasks. Pour into a Black Hole the contents of a star, say like the Sun. All that heat is then trapped and I do mean trapped!

oooooOOOOOooooo

* Light is a thing; gravity is a thing; things can effect each other, so when it comes to the bending of light in a gravitational field, there’s no need for all this nonsense of warped space, time or space-time, which, after all, are not-things but just mental concepts.


oooooOOOOOooooo

* If something quantum happens for no reason at all (i.e. – unstable nuclei goes poof) why doesn’t everything micro happen for no reason at all. Or, if some quantum happenings are just probabilities, why aren’t all micro happenings probabilities.

oooooOOOOOooooo

* An isolated neutron has a half-life of roughly 15 minutes before going poof or decaying into a proton, an electron and an antineutrino. Neutrons that ‘live’ in a community of neutrons like in the nucleus of atoms; as in a neutron star, don’t decay. They are stable in these community relations. That seems like something is screwy somewhere. Why is it so? I thought that might explain why the hydrogen atom (otherwise known as protium) had no neutron (just one electron and one proton), but then heavy hydrogen (deuterium) does have one neutron (plus one electron and one proton) so things get weirder and weirder.

oooooOOOOOooooo

* You obviously relate to being a human in a human-sized world. You can imagine being a cat or a dog and living in their world. You can probably extend that down to the world of insects and imagine yourself as a fly or ant or butterfly. At a stretch, you might be able to relate to and imagine yourself as a micro-organism living in say a drop of pond water or in the blood stream. But what about navigating down to the worldview of a photon or an electron? That I suspect is way, way, way too alien to imagine in your wildest dreams.

oooooOOOOOooooo

* We conceive of nanotechnology as building up from micro scratch what technology we want (say micro devices to traverse our blood vessels and clean them up from the inside) by manipulating atoms from the ground up and building whatever we want from those fundamental ‘Lego’ blocks. But what if the fundamental particles are themselves products of nanotechnology?

The Quantum Realm: Part Two

Now the really interesting thing about quantum physics isn’t so much the physics but the philosophy behind it all. Why is it so? What does it mean? That these philosophical issues matter and should be of interest is because you, the macro reader, is made up entirely – from the ground up – out of the residents of the realm of the micro, the inhabitants of the realm of the quantum.

Continued from yesterday’s blog…

As a review, with commentary, these are my takes on quantum strangeness:

Case Study #1 deals with that double slit experiment. IMHO photons fired one at a time at the double slit should not form a classic wave interference pattern with or without slit detectors in place. The concept of superposition belongs in “The Twilight Zone”, though apparently, so the scenario goes, what’s emitted is a particle; what’s detected is a particle; but the flight or pathway in-between is a wave-of-probability. It’s the slit detector that changes wave-of-probability into location, but that exact location must have existed even had the detector (our stand-in observer) not been in place. How does that explain the one photon at a time interfering with itself and causing that classic wave interference pattern? It doesn’t, but it’s a better bet than trying to come to terms with the idea of a thing being in two places at the same time.

Case Study #2, dealing with entanglement, well let’s just say that a particle on one side of the Universe should be independent of the fate of a particle on the opposite side of the Universe. More superposition equals more of “The Twilight Zone”.

Case Study #3: There needs to be a bona fide causality inspired reason why an electron gives away a photon and drops to a lower energy level. It’s not a whim thing. Maybe it’s another photon bumping into the electron and discharging the absorbed photon, maybe not, but it’s not a whim thing.

Case Study #4: Neutrinos should not endlessly change their clothes on route. The fact that they do contributed to some serious reflection that the core of our Sun had actually shut down. Scientists when looking for electron-neutrinos emitted by the Sun’s solar furnace didn’t see enough of them and thought the worst. It wasn’t until much later that they realised they had missed all those electron-neutrinos that the Sun had actually given off but which had changed their attire between the Sun and the Earth.

Case Study #5 notes that if you are made of matter, it would not be a good idea to shake hands with your antimatter twin self! But why matter and antimatter should go poof at all is a bit strange. An electron has a negative charge and its antimatter twin has a positive charge (hence the name positron). They go poof upon contact. But a proton has a positive charge equal and opposite to that of an electron and they don’t go poof when brought into contact so there’s more than just opposite charges annihilating each other at work here obviously. There’s no question that chemical reactions can give off energy, but total annihilation – wow. 

Case Study #6: Quantum Tunnelling should happen for a reason – it doesn’t. Quantum Tunnelling shouldn’t happen instantaneously since that violates the cosmic speed limit – the speed of light. The fact that in the micro world, barriers, well ain’t, makes all human inmates wish they were subatomic particles! 

The overall image that keeps springing to mind is all those Hollywood special effects. They would be an excellent explanation for all of the above weirdness. Think about it!

Finally, we should also note that most of the above examples or case histories involve quantum probability, uncertainty, indeterminism, etc. with respect or relative to the observer which could be you or me.

Case Study #1 suggests that photons (or electrons or any other fundamental particle) are in a superposition of state, which suggests that they can be apparently in two (or more) locations at the same time, and it’s only based on probability as to exactly where that location is. But it is in just one location as the addition of actual slit detectors verifies. So, the key point is that the photon or electron or whatever is 100% at a specific set of coordinates even if the double slit experiment suggests that the photon or electron or whatever is smeared out over a wide ranging area and only probably here or probably there.  So probability really bites the dust since location (one slit or the other) is confirmed by observation – there’s location, location, location; not probable, probable, probable!

In Case Study #2 we have more about that superposition of state whereby a particle may actually be a particle or an antiparticle (probability is 50/50) or spin up or spin down (probability 50/50). But you know, and I know, that in reality, one particle IS a particle (probability 100%) and the other IS an antiparticle (probability 100%) or one particle IS spin up (100% probability) and the other IS spin down (100% probability). There is no indeterminacy even if there is no observer, there is only determinacy, positive actuality, whether or not one or the other is observed. There is no across the universe communication. There is no ‘spooky action at a distance’. There is no probability involved other than 100% probability, otherwise known as a sure thing.

In Case Study #3 we have an electron that absorbs a photon’s energy and thus quantum jumps to a higher energy level. It then becomes a matter of probability as to when that electron emits that photon and jumps back down to a lower energy level. But, as in the case of radioactive decay, the odds are 100% that it will happen. Probability need not apply here. Probability is not applicable. The key concept here is again, ‘sooner or later’.

In Case Study #4, we might not know why the neutrino changes clothes, or exactly when and under what circumstances, so, as far as we are concerned it’s all boiled down to statistical probability what clothes any particular neutrino will be wearing when detected. However, there’s no doubt in my mind that causality is operating and that it’s 100% certain that the neutrino is wearing the clothes that causality has dictated. There’s no probability involved, only the probability that we’re probably pretty dumb for not figuring out why.   

Finally, in Case Study #5 somehow particles and antiparticles seemingly ‘know’ when they meet and greet whether to go poof or not go poof. The mystery is how they ‘know’. But it’s total certainty one way or the other and the observer has no relevance or say in the matter.

Case Study #6: Quantum Tunnelling, as already noted, happens for no reason at all. It’s responsible for radioactive decay which happens for no apparent reason at all. There is no way, rhyme or reason that enables one to predict when a quantum tunnelling event will transpire. It’s all probability. Either that, or a subatomic particle has a free will mind of its own and the knowledge and the ability of a Harry Houdini.

I have one other observation while on the issue of causality and probability if you please. If something quantum happens for no reason at all (i.e. – unstable subatomic nuclei goes poof) why doesn’t everything micro happen for no reason at all. Or, if some quantum happenings are just probabilities, why aren’t all micro happenings probabilities. Now IMHO if 99.999% of all physical effects can be traced back to one or more causes, it’s pretty safe to suggest, even conclude if you’re a betting person, that 100% of all physical can be traced back to one or more causes, even if those causes remain as yet unknown.

Lastly, consider and reconsider the quantum mantra: Anything that isn’t forbidden is compulsory; anything that can happen will happen. Does that sound like a probability statement to you?

I suggest this puts the kibosh on quantum physics being steeped in probability. There is no probability once you eliminate the observer and the observer’s fixation on either where things are; where something is, or whether something is or is not going to happen, and when something is going to happen. Before there were observers, things were somewhere, fixed and absolute, things did their thing without any guesswork or decision-making involved, and things happened sooner or later with absolute certainty.

The Quantum Realm: Part One


Now the really interesting thing about quantum physics isn’t so much the physics but the philosophy behind it all. Why is it so? What does it mean? That these philosophical issues matter and should be of interest is because you, the macro reader, is made up entirely – from the ground up – out of the residents of the realm of the micro, the inhabitants of the realm of the quantum.

If you take quantum physics to its logical conclusion, you can only deduce that those residents of the quantum realm, those elementary particles, have some very strange properties bordering  on self-awareness, consciousness, quasi-free will, a sort of ‘mind’ of their own but programmed with the social mores of quantum-land. They have the ability to ‘know’ things about their external world and their relationship to that. They can make decisions with respect to those relationships and act accordingly within their programming. They are not totally unresponsive and inert little billiard balls.

I’m also aware that such an assertion crosses the boundary between my being rational and being irrational. I mean how could an electron for example ‘know’ anything and make decisions? Such a proposition makes alien abductions, the Loch Ness Monster and the realm of astrology seem downright normal and acceptable and within the realm of conventional logic! But there is experimental evidence and observations to back this up.  

Case Study #1 – The Double Slit Experiment: Take the infamous double slit experiment (referenced in any and all tomes on quantum physics). Send a stream (lots and lots and lots) of photons at two parallel slits that have a target board of sorts behind them that show where the photons land after they pass through the dual slits. The photons pass through both slits and form on the target board a classic wave interference pattern, thereby showing that electromagnetic radiation, in this case visible light, is a wave. So far; so good. Now fire one light photon at a time at the dual slits, such that one photon will pass through the slits and reach the target board before the next photon is released. What you get – wait for it – is a classic wave interference pattern! That’s ridiculous. It’s as if one photon passes both slits at the same time and interferes with itself. That’s very funny peculiar, not funny ha-ha. In fact, it’s straight out of the “Twilight Zone” again. But wait, it gets worse. Now rerun the one photon at a time experiment but set up a detection device at each slit in order to determine if the photon goes through just one slit or through both. What happens is that the lone photons, fired one at a time, is indeed detected going through one slit or the other slit but not both simultaneously and thus, as you would expect, the classic wave interference pattern vanishes to be replaced with two separate and apart lines on the target board. That’s totally nuts since without detectors at the slits you get that classic wave interference pattern; with detectors, no such pattern. The question is, how did the photon ‘know’ the detectors were there and thus change their behaviour?

Case Study #2 – Entanglement: In the double slit experiment where one photon went through both slits simultaneously, the photon was said to be in a state of superposition – it could be in two places at the same time. In this new study we have two particles with a common origin, linked in some way, and released together out into the wilderness, sort of like Hansel and Gretel. Unlike the fairy tale, the two particles fly off in differing directions. So far; so good. The particles are not quite identical, just like Hansel and Gretel are not quite identical, but complementary, as one particle might be the antiparticle of the other or one is either spin up or spin down and the other is either spin down o spin up. The two particles are again considered to be in a state of superposition – each is simultaneously a particle and its antiparticle; or both are in a state of spin up and spin down. In other words, as in the case of the double slit experiment, there is doubt about who’s who and what’s what until a detector is put into place. I this example both particles fly off until they are on opposite sides of the Universe. Then, a detector is put into position in the pathway of one of the pair (i.e. – someone peeks). When someone peeked (i.e. – the detector detected) as in the double slit experiment, the photon was required to go into an either/or state. Ditto here. If the particle turns out to be Hansel, you know the particle on the opposite side of the Universe must be Gretel. Or, if one particle is observed to be an antiparticle, or say spin up, its partner clear across the Universe instantaneously must cease its superposition of state and become a particle or solidify into a spin down state. That one particle across the Universe somehow ‘knows’ that the superposition of state jig is up since its counterpart has been caught in the act (i.e. – observed or detected). Einstein had a phrase for this. He called it “spooky action at a distance”. Einstein wasn’t happy since this instantaneous communication implied superluminal speeds, faster than the speed of light, which his Special Theory of Relativity gave the thumbs down to. Now apparently, if I’m to understand things correctly, it’s noted that restrictions on the speed of light as the ultimate cosmic speed limit only applies if actual information is being transmitted. Pure gibberish can be transmitted instantaneously and ‘communication’ between two entangled particles isn’t actually information. How the cosmos ‘knows’ whether or not something is, or is not, bona fide information and thus employs photons travelling at the speed of light, or gibberish and thus allows instantaneous ‘communication’, is, IMHO gibberish! The whole issue is resolved if you just eliminate the concept of superposition of state. Something cannot both be and not be at the same time in the same place.

Case Study #3 – Electron Energy Levels: We are aware from elementary chemistry class that there is a cloud of electrons that surround the nucleus (protons plus neutrons) of atoms. Nucleus plus electrons equal whole atoms. The electrons only exist in specific quantified energy states. If they didn’t, they’d collapse and crash into the nucleus and that would be the end of chemistry as we know it! An electron can absorb a unit (or a quanta) of energy, or maybe two (or more) units and jump up a notch or two or three, or give off a unit(s) of energy and drop down a notch or two or three (but never to zero and hit the nucleus). The energy is absorbed or emitted by the absorption or emission of photons. So here comes along a photon minding its own business and runs smack into an electron which gobbles it up and jumps into the next higher energy state. Okay, that makes sense, so far; so good. That’s an example of cause-and-effect. The issue arising is how and why does the electron release the photon from bondage at a later stage and drop back down a level in energy? There seems to be causality working in one direction (absorbing the photon) but not the other way around. So it almost appears as if the self-aware electron wills itself rid of the photon at some point in time and drops down into a more comfortable energy state. However, I gather that there’s a possible explanation in that another photon comes along, hits the electron, and knocks the first photon out thus dropping the electron to a lower energy state. Since nobody has ever witnessed a photon hitting an electron, I guess that’s all conjecture. Still, any natural explanation is better than none.

However there are many other instances apart from the scenario of an electron in ‘orbit’ where electron-photon intersections (absorption and emission) are described, most notably in those [Richard] Feynman diagrams known and loved by particle physicists everywhere. These diagrams illustrate the various electron-photon exchanges but lack explanation as to how photons are given off or escape from the electron’s clutches. It’s all rather mysterious, rather like radioactive decay. 

While on this subject, I should point out another anomaly. Electrons can have just-so quanta energy levels, like 1, 2 3, etc. but not in-between. Energy states of say 1.5 or 2.2 or 3.7 are not allowed. So, when an electron jumps up or down an energy level or two to another energy level, they must do so without going through the spatial intermediaries. First they are here; then they are there, but never in-between. That’s all closely related to the concept of quantum tunnelling where say you are on one side of a wall and then you are on the other side of the wall but you didn’t go through, up over, dig under, or go around the wall. You can’t do that, but elementary particles can. Neat trick that one.

Case Study #4 – Neutrinos: There are three types of neutrinos. There are electron-neutrinos; muon-neutrinos and tau-neutrinos (just like there are electrons, muons and tau particles). Neutrinos, and their antiparticle counterparts, are given off in numerous ways like in various nuclear reactions taking place in the hearts of stars, including our Sun. Billions of these neutrinos pass right through you (without harm) each second. So far; so good. What’s odd is that while in transit, each morphs or shape-shifts into the other neutrino forms and back again and forth and back and forth. It’s like one was in its birthday suit, one in casual wear and one in formal attire and on their journey always keep changing their attire. There doesn’t appear to be any causal reason for this, so perhaps this is what is known as neutrino free will!

Case Study #5 – Antimatter: We’re all aware of the concept of antimatter. Each fundamental particle has an equal but opposite counterpart called its antiparticle. The most common example is the electron and the anti-electron, otherwise known as the positron. We’re also aware that when a particle meets and greets its antiparticle you get a big ka-boom! The two will annihilate each other producing pure energy. But, and this is my understanding, it has to be a particle and its very own corresponding antiparticle. So an electron meets and greets a positron – ka-boom. And so if a proton and an anti-proton meet and greet – ka-boom. But if a proton and an anti-electron (positron) meet and greet – nothing happens because they are not equal and opposite though they are matter and antimatter. Ditto if an anti-proton and neutron meet and greet – nothing happens. The question arises, how do these various particles and antiparticles recognise friend from foe? When foes meet like the positron and the electron, its annihilation. When a positron meets a proton, it’s a friendly meet and greet. How do these particles ‘know’?

Case Study #6 - Quantum Tunnelling: Every now and again we just want to bust out of our day-to-day existence and escape to that greener grass on the other side of the fence. Alas, there’s usually some barrier, economic, geographical, language, cultural, etc. that prevents us from busting out. Wouldn’t it be nice if we could wave a magic wand and bust through whatever factor(s) is holding us back? Well, sadly to say, it’s not usually the case where we can. Lottery wins are few and far between, and even if money were no object, there are other considerations holding us back from that get-up-and-go. Subatomic particles also face barriers in their micro world, barriers of matter and energy, fields and forces, which prevent them from doing their thing. However, subatomic particles have sold their soul to the devil that inhabits quantum land and in exchange have been issued a get-out-of-jail card. It’s called quantum tunnelling and it suggests that subatomic particles can tunnel around, over or through any matter and energy, force or field, restriction. The interesting bit is that the tunnelling happens for no reason at all, involves absolutely no effort on the part of the tunneller, and it all happens instantaneously. So, an electron on one side of a brick wall can instantaneously find itself on the other side without any causality in operation. It’s like our Edgar Rice Burroughs hero John Carter who just wishes himself to Barsoom (i.e. – Mars) and there he is! Perhaps quantum tunnelling is the micro version of the macro wormhole!

In general I think you’d need to agree that there are some decidedly odd goings on here from lack of causality to tiny particles that seem to ‘know’ how to behave either when face-to-face with an observer, or in other either/or situations. Now the odds that these tiny particles actually have the ability to make decisions and exhibit free will divorced from causality, and to ‘know’ things that influence that decision making process is, well nearly infinity to one against. Yet, these anomalies exist and have been verified again and again. So, IMHO, the only other rational explanation is that there must be some sort of guiding power or force, some sort of as yet uncovered hidden variables, maybe programming of some sort, which is responsible. Exactly what that might be – well your guess is as good as mine.

To be continued.

The Lone Electron

One way of coming to terms with the cosmos is to do thought experiments and keeping things simple. When you come to terms with the simple picture, then you can gradually build up the complexity until you start to model the real cosmos. There’s nothing much simpler than to imagine an entire universe that contains one and only one electron – absolutely nothing else: just the Lone Electron. What sort of worldview would our Lone Electron have or we have of it? Actually it would be Boring with a capital B.

With respect to a Lone Electron universe, let’s consider…

ACCELERATION/DECELERATION: None. The same argument applies as with velocity. 

ARROW OF TIME: If there is no time experienced by the Lone Electron, then there can be no arrow of time either. In short, the Lone Electron has no experience of a past, present, or future.

CHARGE: Yes, the electron has a charge of minus one or in other words a negative charge of one unit. However, in order for charge to be meaningful, it has to be acting with or against another charge of which there is none. So, does our Lone Electron have charge in this context or doesn’t it?

COLOUR: An electron is colourless. In any event you need photons, electromagnetic energy, light waves, to transmit (wavelength and frequency) what we (our brains) interpret as colour. Our drab, bland, colourless Lone Electron has no photons to transmit any information about itself, and there are no eyeballs and brains to interpret that information in any event.

ELECTROMAGNETISM: The electron is most associated with electromagnetism and the electromagnetic force. The associated force particle is the photon and electrons can absorb and emit photons (absorb and emit energy). However, in this scenario, there are no photons, so therefore there is no electromagnetic force. In any event, a force is only a meaningful concept if there are two of more particles involved, since, if you are the sum total of things, you can’t give off or receive a force.

ENTROPY: Entropy is a statistical concept where over time, left to themselves, things tend to go from an ordered state to a disordered state, like before-and-after pictures of a wild party. One electron does not make for statistical analysis, so the electron’s state of order or disorder is what it is. It doesn’t increase nor decrease. In fact it’s rather meaningless to philosophize over it. 

EQUILIBRIUM: The Lone Electron is in a state of equilibrium with respect to its surroundings. It could hardly be otherwise since there are no other surroundings except nothingness.

EXISTENCE: Yes, it would be incorrect to say our Lone Electron didn’t exist. However, there’s nothing else around it to verify that existence or give any meaning to it.

GRAVITY: Since the electron has mass, it must have gravity. However, gravity only has real meaning between two (or more) objects with mass, like the Earth – Moon – Sun trilogy; or, in the most traditional of traditional scenarios, the Earth – falling apple scenario that, according to mythology, inspired Isaac Newton. So, in the Lone Electron scenario, it’s pretty meaningless to talk about gravity. In fact it might be meaningless to talk about gravity since gravity is equivalent to acceleration as shown by Einstein. Acceleration implies motion or velocity which in the context of a one electron universe is meaningless. Further, the (hypothetical) particle associated with gravity, the graviton, would be conspicuous by its absence in this Lone Electron thought experiment.

MASS: Yes, the electron has mass. However, it’s yet another particle, known as the Higgs Boson that gives particles with mass, their mass. The Lone Electron has no Higgs Bosons around to give it muscle.

MOMENTUM: None. The same argument applies as with velocity. 

PHASE: There is no phase. One electron does not a solid, liquid, gas or plasma make. An electron, all by its little lonesome, cannot undergo any phase change, like say from a liquid to a solid.

SENSE OF IDENTITY: Our Lone Electron doesn’t have a sense of self-awareness since it isn’t conscious and in any event it has nothing else around it to provide a contrast to itself.

SPACE: Since the Lone Electron exists in this universe, it has to exist in some sort of realm, a concept we call space. However, space is not a thing, and the electron is, so while the two share a common existence, its all apples and oranges.  

SPIN: Our electron will either be spin-up or spin-down. However, orientation, as with velocity, is always with respect to something else. If you removed all of the rest of the Universe (stars, planets, constellations, the Sun, etc.) just leaving the Earth, well the labels North and South Pole become meaningless. There no longer is anything that’s up or down or sideways that one can orient the Earth’s axis to. We know north because that’s where the North Star is located. No North Star. We know south because the Southern Cross is overhead. No Southern Cross. A compass isn’t any help because it’s only an arbitrary convention what we call north and south and in any event the compass is an example of that ‘something else’. 

STRONG NUCLEAR FORCE: The strong nuclear force only applies in keeping an atomic nucleus together. Protons, with a positive charge, would like to repel each other. That they are held in check – confined to quarters - is due to the strong nuclear force. There is no atomic nucleus in a one electron universe, therefore there’s no strong nuclear force.

TIME: An electron is a fundamental particle, a basic building block. It doesn’t change any spots and there’s nothing else around to cause the electron’s spots to change or to ‘witness’ change. No change means the concept of time is meaningless, so therefore, no time unit need apply here for a job.

VELOCITY: No, the concept of velocity is meaningless in this context. Velocity only has meaning when measured relative or compared to something else. If you drive along at sixty miles per hour, that’s relative to the landscape you are driving past, like the surface of the road. The Lone Electron has no landscape for its velocity to be measured against.

WEAK NUCLEAR FORCE: The weak nuclear force governs radioactivity, or the decay of unstable atomic nuclei into more stable forms. One type of radioactivity (Beta decay) can emit an electron, but in the absence of any nuclei, unstable or otherwise, our Lone Electron has no connection with the weak nuclear force since in this, our electron’s universe, there ain’t no such critter. 

So we see how much more meaningful it is to have more than one item per universe. Fortunately, our Universe satisfies that criteria. But the real interesting bit, at least from a philosopher’s point of view, is how some of our most take-it-for-granted concepts that form our worldview, disappear or have no meaning when applied to just one entity. It’s impossible for us to imagine a worldview without there being time, the arrow of time (past, present, and future) or entropy. It’s impossible for us to imagine a worldview without mass or gravity. It’s impossible for us to imagine a worldview without motion. Yet it is entirely possible to imagine a Lone Electron universe where exactly that worldview has to apply!

More Random Thoughts In Physics

* In our Universe there are two kinds of astronomical objects. There are cosmic faucets like stars and anything else that gives off or reflects electromagnetic (EM) waves. That’s the cosmic “In Tray”. Then there are cosmic sinks and drains that absorb electromagnetic waves – Black Holes, the cosmic “Out Tray”.

It would seem to me that over the course of 13.7 billion years, an awful lot of EM (light, IR, UV, radio, microwave, gamma-ray, etc.) photons, not to mention neutrinos and cosmic rays, would have gobbled up and removed from the Universe’s inventory by being sucked into and forever residing in the insides of Black Holes. Since all astronomical observations, hence conclusions about the state of the Universe, rely on the detection of that which is emitted or reflected by cosmic faucets, then it stands to reason that in order to arrive at valid conclusions, what cosmic sinks and drains remove from the Big EM Picture must be taken into account. But is it? I’ve never read any account where the removal of EM photons from the Universe’s inventory has been considered.   

One example that springs to mind is the minor temperature variations in the cosmic microwave background radiation (CMBR) – perhaps those slightly cooler spots are due to a large Black Hole between our measuring device and the CMBR that is sucking up those microwaves before they reach our measuring telescope or space probe or high altitude balloon. I seem to recall cosmologist George Gamow back in the 1940’s making a theoretical prediction that the (then undetected) CMBR would be somewhere between 5 to 7 degrees Kelvin, instead of the roughly 2.7 degrees Kelvin that eventuated. Perhaps, the overall cooler than Gamow expected CMBR is due to Black Holes sucking up lots of those CMBR photons over all those billions of years.

oooooOOOOOooooo

* Another case of non-causality that’s oft given is when an electron gives off a photon, loses energy, and drops to a lower ‘orbit’ around a nucleus. The opposite isn’t lacking in causality however. A photon is absorbed by an electron which gives it additional energy which kicks it upstairs into a higher ‘orbit’ around a nucleus. Now it’s nuts to suggest that a process has causality in one direction while lacking causality in the exact opposite direction. We may not know why an electron gives up a photon and loses energy in the process, but there is most definitely a why causality – of that I’m convinced.

oooooOOOOOooooo

* To be honest, I reject the idea that space itself is expanding. To me distant galaxies are expanding farther and farther apart throughout an already existing space. That makes way more sense. Expanding space appears to me to be a case of getting a free lunch – something from nothing – in violation of standard conservation principles.

Is there any actual observational evidence that proves conclusively that it is space expanding and not cosmic flotsam and jetsam moving apart through existing space? Not to my knowledge but I can think of a possible test that might conclude the issue. Two objects receding apart, like the Earth and the Moon (due to tidal forces) are going with the expanding space grain and should be separating more rapidly than otherwise would be the case due to tidal forces alone. The experiment, measuring the increasing Earth/Moon separation should be a relatively easy experiment to do. Due to the reflective mirrors left on the lunar surface by the Apollo moonwalkers we know the Earth-Moon distance to extreme precision. It should be straightforward whether the Moon is receding from the Earth faster than tidal forces can account for.  

oooooOOOOOooooo

* The cosmos is easily divided into matter and energy related ‘things’ (products of nature) and space and time related ‘not things’ (concepts invented by humans and maybe by other animals). IMHO, ‘things’ are probably those which ultimately reside in the world of the quantum and are discrete. Many ‘not-things’ can be divided and divided indefinitely and are continuous.

oooooOOOOOooooo

* If an electron acquired enough mass (say by being accelerated to near light speed), would it become a Black Hole, and if so, would the ‘inside’ still be an electron, which after all, is considered a fundamental particle? 

oooooOOOOOooooo

* If you like symmetry, then the most perfect object of all things symmetrical is a sphere.

oooooOOOOOooooo

* We frequently read of a “world without time” or “time standing still” or “time doesn’t exist” when it comes to that never-never-land of singularities, be then Black Hole related or that which was at the moment of the Big Bang which somehow created time. I consider that an impossibility since the absence of time means that nothing changes or conversely if nothing every changes it would be meaningless to talk about the existence of time. But the froth and bubble of the vacuum energy is omnipresent (even inside a Black Hole or the structure that was the Big Bang event) and that involves change and therefore the concept of “no time at all” is kaput.

oooooOOOOOooooo

* It is said the electron is a fundamental particle that cannot be divided or split into simpler components. An electron can of course be converted to energy (all mass can be) say by coming into contact with a positron, the electron’s antimatter alter ego. An electron can emit and absorb a photon, but it doesn’t decay into anything simpler. So I gather if you could smash two electrons head on with as much oomph as one could muster, you’d end up with as close to as makes no odds, that is nearly, a case of the irresistible force failing to move (shatter) the immovable (un-shatterable) object. Another case illustrating the irresistible force and immovable state of affairs – it is impossible to isolate a quark (they come as a trio take all) or its force particle, a gluon.

oooooOOOOOooooo

* Space is not the final frontier. The ultimate challenge is to ‘boldly go’ past the event horizon of a Black Hole and see what’s to be seen.

You and the Vacuum Energy

The electron, the proton and the quark are all entities within the realm of particle hence quantum physics. All three carry electrical charge. All three have mass. After those observations, things get interesting, or messy, depending on your point of view.

An electron has a negative charge exactly equal and opposite to that of a proton. Note: the charge is exactly equal, even though the proton has a far greater mass than the electron (some 2000 times heavier in fact, not that there has to be of necessity any relationship between mass and charge).

Now that’s strange since the electron is a fundamental particle but the positively charged proton is a composite particle, made up of a trio of quarks (as it the neutron with no net charge). The proton has two quarks each with a positive 2/3rds charge (up quark) and one quark with a negative 1/3rd charge (down quark) for an overall balance of one positive charge. (The neutron on the other hand has one up quark with a positive 2/3rds charge and two down quarks each with a negative 1/3rd charge, for an overall balance of zero charge – neither positive nor negative.)

Now you might suggest that an electron might be a fusion of a trio of down quarks, each with a negative 1/3rd charge, except the electron, again, isn’t a composite particle, and the mass is all wrong for that scenario. If an electron were a composite of a trio of down quarks, each with a minus 1/3rd charge, the electron would be thirty times more massive than it is – not something particle physicists would fail to take notice of. 

Further, the force particle that governs the electron is the photon; that which governs the quarks inside the proton and the neutron is the gluon, which further differentiates the two things – quarks and electrons. In any event, if you could have a composite particle of a trio of negative 1/3rd down quarks, if that were the case, and it is the case, and it’s called the Negative Delta, you’d also need a composite particle that’s the fusion of a trio of positive 2/3rds up quarks for an overall charge of plus two. To the best of my knowledge there is only one such critter in the particle zoo and it’s called the Doubly Positive Delta. I’m sure you’ve never heard of these Delta particles, which goes to show how much bearing or impact they have on life, the Universe, and everything.

In case you were wondering, there would be an anti-quark of minus 2/3rds charge, and an anti-quark of a positive 1/3rd charge, to yield an anti-proton and an anti-neutron. The anti-proton would of course have an equal and opposite charge to the anti-electron (which has a formal name – the positron). So things are equally as mysterious in the realm of the anti-world.

Question: How do you get 1/3rd or 2/3rds of an electric charge in any event? Of course one could just multiply by three and that does away with the fractions, but that doesn’t resolve the larger issues, like for that matter, what exactly is electric charge and how does it come to be?

Presumably quarks inside of protons and neutrons, and electrons, could have taken on any old values of charge, separate and apart, but didn’t. Why? Is this evidence for a Multiverse (where anything that can happen does happen in all possible combinations); intelligent design (which does not of necessity imply a deity – just a creator, or a programmer); or just a coincidence?

Why is it so? What does it mean? Equal and opposite charges between the proton and the electron would just seem to be one of Mother Nature’s little mysteries.

But something else is odd here. The proton, as noted above, is 2000 times more massive than the electron, but if you weigh up the trio of quarks* that make up the proton, the proton should only come in at roughly 20 times that of an electron. That’s 100 times too small. So where does the other 1980 bits of mass come from? Well the gluon that holds the proton’s (and the neutron’s) quarks together, like the electron’s photon and gravity’s (theoretical or hypothetical) graviton, have no rest mass that add to the total. But the internal jiggling of the quarks and their gluon companions does add a bit more mass to the proton. Remember that motion equals energy which equals mass. Finally, that leaves the vacuum energy to fill the remaining gap.

Vacuum energy: what’s that? There’s no such state as zero energy, so there’s energy around even where you don’t expect it – like in a vacuum. If you have a finite amount of energy in a finite volume, you cannot dilute that amount of energy such that you end up with no energy present. That’s a violation of fundamental conservation laws. So this vacuum energy is present everywhere and experimentally confirmed so that’s not an issue to be debated. The next bit is to recall that Einstein’s famous equation relates the equality between energy and mass. Mass can be converted to energy and energy can be converted to mass. So this vacuum energy can produce what’s known as virtual particles, which exist for nanoseconds (actually way less than that) before recombining, going poof, and returning to the environment again as energy.

Everywhere, anywhere, all the time, these virtual particles pop into and out of existence – your basic transformation of energy into matter (mass) and back to energy again. Again, matter and energy are two sides of the same coin. A little bit of mass can create a lot of energy as the atomic bomb; a lot of energy can create a tiny bit of mass, and virtual particles are tiny, so it doesn’t take much energy to manufacture them. As you might expect, it’s cheaper (uses less energy) to create virtual ‘ping pong balls’ than virtual ‘bowling balls’, and so you get way more of the lighter particles created than the heavier ones. Further, the heavier they are the quicker they go poof again. Not that it ultimately matters but these pop-in pop-out events transpire so quickly that not even the finest and most accurate of Olympic timers could measure their duration. Quantum’s vacuum energy’s virtual pop-in pop-out is all over in the blink of a blink of a blink of a blink (add some more blinks) of an eye.

Oh, one other thing to note, when the vacuum energy creates these virtual particles, they are created in pairs – matter-antimatter pairs to be precise. Now why, when virtual particles are created are they in that form? Matter-antimatter pairs are the only viable way of returning to the vacuum energy the energy that was ‘borrowed’ to create the particles in the first place. It’s like borrowing money from the bank. You’ve got to repay it. If the vacuum energy created, say a pair of electrons, well the energy debt couldn’t be repaid since two electrons can’t annihilate each other back to pure energy. The bank’s money wouldn’t be repaid and there’d be hell to pay instead!

This constant froth and bubble is commonly called quantum fluctuations or the quantum jitters. All that activity, those virtual matter-antimatter particles, completely accounts for the missing mass – the differential between the proton’s quarks’s mass and the proton’s mass. In a similar way, presumably all matter is more massive as a result of these quantum jitters that take place in the vacuum energy, jitters which even permeate the insides of protons and neutrons. So, and I hope you’re sitting down while reading this, a large part of your mass is due to the jittery happenings of the vacuum energy!  

Given the above, I can’t help now but wonder what affect this constant froth and bubble, the quantum jitters, has on the biological body – your biological body. In theory, barring external agents like accidents, there is no real reason why we should age and die. Some diseases are obviously caused by outside agents like bacteria and viruses, but others have more mysterious origins. There are external agents like smoking, alcohol, radioactivity and ultraviolet light which can have detrimental effects. But if you exclude all nasty external agents, why would we age and ultimately snuff it?

The body, your body, my body, your pet’s body, is ultimately a composite of the fundamental particles that make up life, the universe and everything. These fundamental or elementary particles are subject to quantum phenomena. These particles have a volume for those phenomena to operate in. Even in space external to those particles, quantum phenomena operate all the time, anywhere and everywhere. The vacuum energy isn’t somewhere ‘out there’ in never-never-land. It’s everywhere including inside you from head to toe. Virtual particles are being created and destroyed inside you even as you read this, like it or not. All of this too-ing and fro-ing, the constant creation of virtual particles and hence their annihilation (literally a matter-antimatter annihilation) – energy to matter and matter back to energy – must have some sort of wear and tear on biological systems starting at the quantum or micro level and moving on up the line. If something goes wrong at the micro level, it has an obvious ripple effect on up that line to the macro level. Perhaps modern medicine should pay closer attention to quantum and particle physics!

There are probably multi hundreds of thousands of monographs exploring and explaining the workings and maladies of the human body from conception to ultimate demise; from the whole of physiology and anatomy down to the individual organ systems (i.e. – digestive system, respiratory system, nervous system, etc.); the individual organs (stomach, lungs, spinal cord); the tissues that comprise these; the cells that make up the tissues and the biochemistry that works its magic inside the cells. But I doubt if you’ll find in any medical library too many tomes on particle and quantum physics. Yet without particle and quantum physics there could be no cellular biochemistry on up to gross physiology and anatomy.

If all those quantum jitters, those now-you-see-them now-you-don’t virtual particles consisting of matter-antimatter annihilations inside you weren’t bad enough, the micro world isn’t quite through with you. You’re being bombarded 24/7/52 by millions of cosmic rays and neutrinos every second, though fortunately nearly all pass right through you as if you didn’t exist at all. However, the same can’t be said for those matter-antimatter annihilations. There’s no way I can see the creation and destruction of virtual particles (in matter-antimatter pairs) having any beneficial effect on your body, hence my postulating that these quantum jitters might have some, even if partial, effect on some diseases, infirmities, the ageing process, even ultimately death.

There’s no point is worrying about this for there’s not a damn thing you or anyone, not even your family doctor or a particle physicist, can do about it.        

The one saving grace is that the virtual energy is 120 orders of magnitude less than theory predicts, otherwise you and the Universe would be ripped apart – well actually you and the Universe would never have formed in the first place.

*There is some degree of uncertainty in the exact mass of those various quarks because they cannot be weighed in isolation. However, the estimates are probably pretty close to the mark. The error bars aren’t that great.
