Show Me The Evidence!

You will find many claims in science and religious texts that this, that and the next thing is 100% factual and true. Usually, in science at least, those claims are backed up by hard evidence, peer reviewed, and published for the entire world to read and examine. However, that’s not always the case. Claims are sometimes made that such-and-such is factual, but there’s no supporting evidence, which a) wouldn’t be so bad if that were admitted, and b) if those failing to give their evidence didn’t demand hardcore evidence from others for their claims.  

Scientists and science buffs have a near religious mantra when it comes to the claims of what they term the pseudo-sciences, pseudo-scientists and pseudoscience buffs. That mantra is “show me the evidence”; Show Me The Evidence”; “SHOW ME THE EVIDENCE” - And rightly so. In general it is a good step in the advancement of knowledge to require some minimum amount of evidence when someone making a claim that has a good probability of being wrong.

But there’s a whole pot-full of scientific claims (and for completeness, religious claims) that’s given as unquestioned ‘fact’ albeit ‘fact’ with no supporting evidence at hand. These are ‘facts’ taken on pure faith. These ‘facts’ are presented by the faithful, in whatever discipline(s) their ‘facts’ reside in or belong to, as, well ‘facts’ yet offer up nothing in the way of evidence supporting these ‘facts’.

THE DOUBLE STANDARDS

So, it is a double standard to demand evidence from someone else’s bailiwick (say from so-called pseudoscience or the paranormal) while not presenting any evidence for your bailiwick (the sciences; religion).   

In other words, there’s often a double standard, probably linked to one half of the equation having an entry ticket to the ivory tower and the other half of the equation excluded from the ivory tower. Scientists (ivory tower resident) preaching to the layman (not ivory tower resident), usually present less evidence for their convictions than they demand in turn from the layman for their convictions or worldviews.

For example:

The Catholic Church probably demands some quite definitive and sufficient evidence of a miracle as claimed by Joe Faithful, but expects Joe Faithful to swallow hook, line and sinker stories (mythological tall tales IMHO) of a virgin birth, a deity who walks on water, and that Christmas is the actual birthday of Jesus.

It’s no great secret that some scientists believe in the reality of a creator God. Yet while they will accept God-the-Creator based on zero evidence, they will demand solid slab-in-the-lab physical evidence from their peers (not to mention the great unwashed layperson) for their bailiwicks and worldviews.

Biologists confront Bigfoot: Show us the evidence!

-         Eyewitness sightings, even multiple eyewitness sightings – not evidence.
-         Physical traces, like dung or hair – not evidence.
-         Films and photographs – not evidence.
-         Plaster casts of footprints – not evidence.
-         Required: One corpse, skeleton or live specimen – now that’s evidence.

Physical scientists confront UFOs: Show us the evidence!

-         Eyewitness sightings, even multiple eyewitness sightings – not evidence.
-         Radar ‘sightings’ – not evidence.
-         Eyewitness sightings backed up by radar ‘sightings’ – not evidence.
-         Films and photographs – not evidence.
-         Professional expertise and witness quality – not evidence (unless it turns a UFO into an IFO).
-         Ground traces – not evidence.
-         Physiological effects – not evidence.
-         Electromagnetic effects – not evidence.
-         Required: Stuff to place on the slab in the lab for analysis, or even a ‘Gray’ corpse – now that’s evidence.

Alas, that sort of tin bucket definition of what is, and is not, evidence wouldn’t hold any legal or courtroom water being so full of holes. But, then again the courtroom of science isn’t the courtroom of Perry Mason.

Okay, let’s flip over the coin and see what sorts of evidence some scientists and theologians present for their established, traditional and acceptable bailiwicks. 

COSMOLOGY: SHOW ME THE EVIDENCE…

- For a Multiverse as opposed to a Universe. There is no evidence for the former relative to the latter.

- That the Big Bang actually created space as opposed to an event that happened in preexisting space. There is no evidence for the former relative to the latter.

- That the Big Bang actually created time as opposed to an event that happened in preexisting time. There is no evidence for the former relative to the latter.

- That the Big Bang actually created matter and energy out of absolutely nothing as opposed to an event that happened within the confines of preexisting matter and energy. There is no evidence for the former relative to the latter.

- That space itself is expanding as opposed to the contents within space expanding through that existing space. There is no evidence for the former relative to the latter.

- That the singularity at the heart of a Black Hole is actually infinite in density and occupies zero volume as opposed to just being very dense and something that occupies a small but finite volume. There is no evidence for the former relative to the latter.

PHYSICS: SHOW ME THE EVIDENCE…

- That there really has to be a Theory of Everything (i.e. – quantum gravity) as opposed to there being two separate and apart sets of ‘software’ running the cosmos. There is no evidence for the former relative to the latter.

- That the elementary particles are actually tiny vibrating strings as opposed to tiny little ‘billiard balls’. There is no evidence for the former relative to the latter.

- That there are an additional six spatial dimensions as opposed to the standard three (length, width and height). There is no evidence for the former relative to the latter.

- That there is such a thing as Supersymmetry (SUSY) as opposed to just normal symmetry. There is no evidence for the former relative to the latter.

- That the physical constants are indeed constant throughout all of time and space and under all conditions as opposed to really being variable depending. There is no evidence for the former relative to the latter.

- That mathematics exists independently of the human (or biological) mind as opposed to mathematics existing solely within the confines of intelligence. In other words, in a Universe before life evolved, did mathematics exist? If so, show me the evidence. There is no evidence for the former relative to the latter.

- That we exist in a really real reality as opposed to existence as virtual reality. That is, that our Universe actually exists and isn’t just a simulated universe – wallpaper to our ‘reality’. There is no more evidence for the former than there is relative to the latter.

BIOLOGY: SHOW ME THE EVIDENCE…

- That ETI (extraterrestrial intelligence) actually exists to give justification to all the time, effort and cost of SETI (search for extraterrestrial intelligence) to pin down ETI’s celestial coordinates as opposed to humanity being the be-all-and-end-all in terms of advanced technological civilizations. There is no evidence for the former relative to the latter.

- That human beings are the evolutionary product of natural selection as opposed to artificial selection, in either case from primate ancestors. There is no evidence for the former relative to the latter.

ANOMALIES: SHOW ME THE EVIDENCE…

- That all ‘crop circles’ are hoaxes and are the sole work of the human being as opposed to some have a more paranormal explanation. There is no evidence that the former is the case relative to the latter.

RELIGION: SHOW ME THE EVIDENCE…

- That a monotheistic deity (i.e. – God) actually exists as opposed to there being no deity at all. There is no evidence for the former relative to the latter.

- That the Bible is the literal word of that God as opposed to the recorded or written word of the human imagination. There is no evidence for the former relative to the latter.

- That Heaven and Hell are actually geographical places as opposed to having existence solely within the human imagination. There is no evidence for the former relative to the latter.

- That there really was a universal flood as opposed to accounts in mythology from around the world of separate and apart major flooding events. There is no evidence for the former relative to the latter.

- That the events (for example) in Exodus actually happened as opposed to being pure mythological fiction. There is no evidence for the former relative to the latter.


Oh dear!

Dare I say it, “extraordinary claims [and most of the above are] require extraordinary evidence”. Heck, even a little bit would be an improvement. But there are many examples where those who demand the proof of other’s pudding can’t produce any pudding when it’s their turn to cough up.

It’s unfortunate, but double standards rule.

The Russell Stannard Questions: Part Three

There are many Big Questions in science, many of which go back to the ancients, even back into prehistory in all probability. One of the best modern set I’ve found recently were sidebars in a book by Emeritus Professor of Physics at the Open University, Russell Stannard. These are my answers, thoughts and commentary to those Big Questions. Many readers might have ‘fun’ trying to come to terms with these in their own way based on their own worldview.

Continued from Part Two.

Q. Does the loss of simultaneity for events separated by a distance invalidate the notion that only the presence exists?
A. This is one of those ‘paradoxes’ of those Theories of Relativity whereby, since things are relative, to one observer A happens before B; to another observer A and B are simultaneous happenings; and to yet a third observer, B happens before A. Since all observers are correct according to their specific frame of reference, the concept of ‘now’ is flexible. There is no absolute ‘now’. Another example is that whatever you observe, you observe ‘now’ yet what you observe actually happened in the past. The sunlight you see ‘now’ is now eight minutes old. However, it’s quite conceivable that you could instigate a universal ‘now’ and freeze the universe by snapping your fingers “STOP NOW”. That “STOP NOW” message would propagate instantaneously throughout the entirety of the universe. You, being immune from that “STOP NOW” command, would be free to navigate and explore the cosmos and see the universe as it appeared at that one ‘now’ instant – ‘now’ being of course the present. Only the present, the universal snapping your fingers ‘now’ exists. The interesting thing is that ‘now’ is such a short interval that your definition of the length of ‘now’ is vastly longer than what ‘now’ exists in in reality.

Q. What is time?
A. Time is a not-thing. Time is a concept that resides in the mind and cannot be detected with any of your senses. Time has no physical properties. Time is mathematics (a human invention), a way of measuring a particular thing. That thing is change, or rate-of-change. If there is no change, it is meaningless to talk about time. Time does not exist independently of change.

Q. Does the perceived flow of time require there to be two types of time?
A. The two types of time in question are physical time (the tick-tock of a clock; the cycle of the lunar phases) and mental time (where an hour can seem like a minute; a minute can seemly last for an hour). So there is real time, and subjective time. But time in any guise is a not-thing; an illusion; a concept. Only change is real and the rate of change, real or perceived, is what we call time – physical or mental. One could, if one wanted make a variable rate of change into a constant. Normally we hold physical time as a constant – tick-tick-tick-tick – at a rate of one-second-per-second (or one-day-per-day, etc.). We can count the number of ticks between say two red cars passing by on the road in front of our house. But you could say the interval between any two red vehicles is a constant. It is one unit or one tick per interval of red car time. That means that everything you associate as being regular like one-second-per-second or a 24-hour-day would become irregular. One ‘day’ might equate to 100 red car interval ticks. The next ‘day’ it might be 200 red car interval ticks long (since there happen to be double the number of red cars passing by on ‘day’ two as compared to ‘day’ one). If you define a ‘day’ as say 100 red car interval ticks, then ‘day’ two above would really be ‘day’ two plus ‘day’ three. Well, you can see how that sort of reckoning would screw up your biological clock! You’d have a ‘day’ off work between 1000 and 1100 red car interval ticks; the next ‘day’ off work between 2000 and 2100 red car interval ticks, etc. In the case of the 1000-1100 interval, that might be a long and restful ‘day’ but the 2000-2100 interval could be extremely short! You could do the above time experiment, at least as a silent and private intellectual exercise. Otherwise people would carry you off to the funny farm! However, if time were really real, then time couldn’t be manipulated as per the red car interval example. But time isn’t real so you can twist it around your little finger. Thus, the flow if time is indeed perceived, but that doesn’t make it something of substance. So, one kind of time, two kinds of time – it’s irrelevant.  

Q. How are we to understand the built-in creativity of the physical world?
A. Human beings are highly creative beings. We create 2-D and 3-D art and architecture; sports and games; music and storytelling; designing experiments; create new food recipes, create computer simulations, etc. We love to indulge in the ‘what if’ game. Apparently so does the Universe! From a primeval ‘fireball’ of elementary particle ‘soup’, the cosmos created forces and fields, atoms and molecules, and stuff and structures* like galaxies and stars and solar systems full of planets and associated debris, but from our biased point of view or perspective the Universe created life and us. If this creation in particular was inadvertent, it borders on a near miracle given all those pieces of the jigsaw puzzle that have to come together just so. If life was a deliberate creation then you are down to postulating either an infallible supernatural deity (or deities) or a probable flesh-and-blood and fallible Supreme Programmer. 
·        But not just galaxies but spiral galaxies and barred galaxies and elleptical galaxies and irregular galaxies; not just stars but dwarf stars and giant stars and neutron stars and quasars and Black Holes and binary star systems too as well as stars that burp and stars that explode; not just planets but gas giants and icy giants and rocky planets (and I’m sure there’s no planet ever envisioned by any science fiction writer that doesn’t have a real counterpart somewhere out in the cosmos).

Q. What significance, if any, ought we to attach to the self-ordering nature of matter?
A. The cosmos is a highly ordered place. The only real question is why it is so. There are roughly about 60 elementary particles (and antiparticles) grouped into three generations. There’s no theoretical reason why there couldn’t have been trillions of elementary particles grouped into hundreds of generations, or no generational structure at all. The fundamental particles can only combine in just so many ways – you can’t have an atom consisting of one neutron, 5 protons and ten electrons. Atoms can only combine in just so many ways. There are a lot more ways atoms can’t combine than ways they do. The same applies for molecules combining. The ancients noted this ordering by suggesting that everything has its natural place in the cosmic scheme of things. Solids (earth) seek ground level; liquids (water) go down too but rest on top of solids; gases (air) hover above solids and liquids and heat (fire) tries to rise through gases and occupy the top rung. The planets don’t orbit the Sun in a square orbit one year, then switch to a rectangular orbit the next year and switch again to a triangular orbit the year after that. The lunar cycle follows its steady rhythm; ditto night follows day that follows night that follows day, etc. Thunder follows lightning. Plants grow upwards while plant roots grow downwards. In other words, causality operates. If you have X, Y follows (but not A, B and/or C). So the fact we have ordering is significant. But, consider this. Software is the same. Your PC is predictable. If X, then Y (but not A, B and/or C).

Q. The problem of understanding things in themselves.
A. No matter what sort of thing you wish to describe, its properties, you eventually exhaust appropriate concepts and language to dig any deeper. You often hit an ultimate barrier when you come up against the ‘what’ and ‘how’ and ‘why’ questions. We know there is gravity but ‘why’ gravity at all and ‘how’ does gravity actually work. We know an electron has a negative electric charge of one unit but ‘what’ exactly is electric charge and ‘why’ does the electron have the value of electric charge that it has. The problems disappear if one suggests well, this is the programming, the software code that gives us the illusion of all things gravitational and another software code that determines that there be an negative electric charge on an electron and what the value is, also properties that are totally an illusion, or virtual reality. Ultimately those ‘what’, ‘how’ and ‘why’ questions like why introduce gravity and why have an electric charge can best be answered by those who do the (supreme) programming.
 
Q. Why are there three generations of particles?
A. Only the bottom generation of particles plays any role in our day-to-day perception of life, the universe and everything. The second and third generation have bugger-all to do with life, the universe and everything. There is something screwy somewhere! Mother Nature went over-the-top and made way too much of a good thing which is not how we tend to view Mother Nature. Mother Nature is frugal, not extravagant. However, all these additional generations of particles might be the consequence of programming. Natural or software, it’s a mystery that has no obvious rational explanation which suggests to me the irrationality of intelligence. A common theme when it comes to intelligence is that if it is worth doing, it is worth overdoing.

Q. Can we ever be sure that GUT is correct if we cannot experimentally test it at the appropriately high energy?
A. A GUT is a Grand Unified Theory, some sort of unification between the three quantum forces – the strong nuclear force, the weak nuclear force, and electromagnetism. One suspects that at the time of the Big Bang event all three forces were unified, only separating or undergoing phase transitions into distinct entities as the universe expanded and cooled. Unfortunately, the energy levels at the point of the Big Bang are such that they are beyond our abilities to achieve and thus any GUT cannot be experimentally confirmed, only theoretically ‘confirmed’. So, if there are competing GUTs, it will be difficult to separate the men GUTs from the boy GUTs. No, unless there’s a breakthrough in experimental high energy physics, the answer is “no”.

Q. Shall we ever be able to verify proton decay?
A. If protons theoretically decay, akin to how neutrons can decay, and you have a large enough collection of protons (that’s easy to accomplish) then it is a straightforward exercise to verify proton decay, even if on average it takes any one proton trillions of years to go poof since if you have trillions of protons on hand, you should see several go poof every year. Such experiments have come up empty. Protons don’t decay so there’s something screwy with the theoretical concept somewhere.

The Russell Stannard Questions: Part Two

There are many Big Questions in science, many of which go back to the ancients, even back into prehistory in all probability. One of the best modern set I’ve found recently were sidebars in a book by Emeritus Professor of Physics at the Open University, Russell Stannard. These are my answers, thoughts and commentary to those Big Questions. Many readers might have ‘fun’ trying to come to terms with these in their own way based on their own worldview.

Continued from Part One.

Q. Do the physical constants change with time?
A. There is apparently some evidence for this as well as a lot of theoretical speculation that some of the beloved physical constants, like the speed of light, may not be constant but variable over those immense cosmic time frames. In the Simulated (Virtual Reality) Scenario, one could argue, based on experience, that computer code or software needs tweaking every now and then. If fact, we’re all used to getting those software upgrades. So, perhaps our Supreme Programmer, as the simulation scenario unfolds, decides that some tweaking or upgrading is required and we observe that as a change in one or more physical ‘constants’.

Q. Why is the universe life-friendly?
A. The universe is both bio-friendly and not bio-friendly. 99.999% (add a few more 9’s here) of the cosmic environment is decidedly bio-unfriendly and would snuff you out so quick-smart you wouldn’t know what hit you. Of course the cosmos is also bio-friendly otherwise you wouldn’t be here reading this. If you reject a supernatural explanation, that leaves coincidence, a multiverse, or software. Coincidence is stretching things since there are just so many dials that have to be set to a very narrow range. The multiverse appeals to probability statistics – think of those millions of monkeys at millions of typewriters one of whom will type “Hamlet” word-for-word – eventually. That leaves software, or in other words a Supreme Programmer programing our universe in a bio-friendly way. 

Q. Are there universes other than our own?
A. If you reject the supernatural and the software and coincidence, then you are left with the multiverse scenario to explain why we are here. We are in the one successful universe that produced that word-for-word typing of “Hamlet” by those millions of monkeys.

Q. What is the nature of dark matter?
A. Dark matter doesn’t actually exist. It is inferred only because the fallible Supreme Programmer made an ‘oops’ when programming the minimum required for the cosmic background wallpaper in our Simulated (Virtual Reality) Universe.

Q. Is the universe infinite in size, and if so, what exactly does that mean?
A. The universe is infinite in size solely on the philosophical grounds that one can always ask the question ‘what is beyond’ this barrier or at right angles to where I am. There always is a beyond, even if you have to postulate a higher dimension to get there, as it inhabitants of 2-D Flatland can escape by going into the third (higher) dimension that’s so familiar to us. In the Simulated (Virtual Reality) Universe scenario, well we’ve probably all seen computer/video games that have a wraparound feature. Something goes off the screen to the right or at the top and reappears at the left or at the bottom. That’s an infinite loop. To the inhabitants, it’s an infinite size where you can go round and round the mulberry bush for all eternity.

Q. Is there extraterrestrial life, and if so, how do we humans stand in comparison as regards intellectual capacity?
A. Given the vastness of the cosmos, and the sheer number of galaxies in the observable cosmos, and the numbers of stars per galaxy with associated solar systems and the number of planets per solar system not to mention possible rogue/orphan planets and how interstellar cosmic organic chemistry associated with life is, well, cosmic, etc., you would have to be pretty brave to bet the family farm arguing Planet Earth being the proverbial cosmic IT when it comes to life. Even going up the chain from the origin of life ‘living’ molecules to unicellular life to multicellular life to intelligent life to technologically advanced life forms and advocating extreme difficulty in getting from one step to the next step on up the line, there must be – if you’re a betting person – millions of advanced extraterrestrial civilizations throughout the cosmos and a goodly number in our galaxy too. Further, we humans are the new boys on the block, so the odds are that any other extraterrestrial intelligences will have been around way longer that we have, and thus have evolved greater intellectual capacity that we have yet achieved. However, the interesting bit is that once intelligence is achieved, natural selection gives way to artificial selection, and part of that artificial selection might ultimately be the transition from biological intelligence to artificial intelligence, artificial intelligence which will further evolve via artificial selection as machine intelligence designs ever better machine intelligences.

Q. How are we to account for the observed value of the dark energy?
A. There is only ‘dark energy’ if the Universe is really accelerating when it comes to the expansion rate of the Universe. Cosmologists had to invent some sort of explanation for this anomalous observation, so why not call it ‘dark energy’ even if they haven’t the foggiest idea what it actually is. Now you know, and I know, that the Universe cannot be expanding at an ever accelerating rate due to that little factor we all acknowledge called gravity. Gravity exists; so-called ‘dark energy’ is theoretical, ad hoc, an epicycle and iffy at best. An accelerating Universe is like your car going uphill at an ever faster and faster rate without you putting the pedal to the metal. I’m reasonably certain that what has been interpreted as the expansion rate of the Universe accelerating has some other explanation. Perhaps not all type 1A supernovae are really peas-in-a-pod and thus are not the standard candles we think they are. Perhaps the velocity of light isn’t a constant after all and changes over cosmic time. That would throw one heck of a monkey wrench into the scenario. So, ‘dark energy’ doesn’t have a value since the Universe isn’t really accelerating. If, however, the [Simulated] Universe really is accelerating, then that’s obvious evidence for our Supreme Programmer screwing up the cosmic background wallpaper software. It’s just an ‘oops’, an oversight in overlooking the consequences of programming this variable at this value instead of some other variable at some other variable.

Q. Does the density of the dark energy remain constant with time?
A. There is no ‘dark energy’ IMHO so the question has no relevance. However, if the value or density of the alleged ‘dark energy’ is allowed to vary over cosmic time, then one could just about explain any observation relating to any value of the expansion rate of the Universe.

Q. Is there a connection between today’s repulsion of the galaxy clusters and the period of inflation?
A. If there was such an animal as inflation that happened quick-smart and cheek-by-jowl with the Big Bang event, well some force or other had to be responsible for blowing up that cosmic balloon. Fast forward to today and we see galactic clusters moving away from each other as if each had a bad case of B.O. Again, there must be some force acting on these clusters repelling them. I though conventional wisdom put that down to the so-called ‘dark energy’ but if there really is a ‘dark energy’ and if there really was a repulsive force that drove what we allege was cosmic inflation, it might be odd if the two repulsive forces in question didn’t share some sort of physics ancestry assuming they aren’t exact clones.

Q. Why is there more matter than antimatter?
A. Theory says that there should be equal amounts of matter and antimatter ‘created’ at the time of the Big Bang event. There’s not. Anytime you have a situation where something should be but isn’t (or conversely something shouldn’t be but is), then something is screwy somewhere. The missing antimatter can’t be adequately explained naturally, but a Supreme Programmer could have programmed that difference deliberately, since programming equal amounts of matter and antimatter would have resulted in a pure energy virtual reality cosmos, which, truth be known, would be rather boring.

Q. How are we to understand the true nature of space?
A. Space is a not-thing. You cannot see, hear, touch, taste or smell space. Space is a concept, actually a mathematical concept called volume. Volume is the third dimension, and dimensions are also a concept – a not-thing. Space is the container that holds within real things, like you and me. So the true nature of space is the exact same as the true nature of Wednesday.

Q. Is space infinitesimally divisible?
A. Since space is a not-thing, that is just a concept invented and used by the human mind (as well as within the minds of numerous non-human life forms) to measure the mathematical concept of volume and to assist with navigation, then space is infinitesimally divisible since it has no physical properties that are so fundamental that they can’t be divided one more time.

Q. Is time infinitesimally divisible?
A. Since time is a not-thing, that is just a concept invented and used by the human mind (as well as within the minds of numerous non-human life forms) to measure and deal with change, then time is infinitesimally divisible since it has no physical properties that are so fundamental that they can’t be divided one more time.

Q. Does four-dimensional spacetime imply that the future is, in some sense, fixed?
A. If causality rules like I think it does, then yes.

Q. Does this in turn compromise our sense of free will?
A. Free will? What’s that? We think we have free will but that’s an illusion. No doubt a character in a video game believes she has free will, but we know better, don’t we!

The Russell Stannard Questions: Part One

There are many Big Questions in science, many of which go back to the ancients, even back into prehistory in all probability. One of the best modern set I’ve found recently were sidebars in a book by Emeritus Professor of Physics at the Open University, Russell Stannard. These are my answers, thoughts and commentary to those Big Questions. Many readers might have ‘fun’ trying to come to terms with these in their own way based on their own worldview.
The following questions in italics are taken verbatim from those poised by Russell Stannard in his 2010 book The End of Discovery [are we approaching the boundaries of the knowable?]; Oxford University Press, Oxford. I consider these typical of the sorts of modern Big Questions that are part and parcel of the philosophy of modern science, especially physical science.
My answers are based mainly with the thought of our being in a Simulated (Virtual Reality) Universe that has been constructed by one or more Supreme Programmers. However, some of the answers apply regardless of what the nature of our ultimate reality is.

THE RUSSELL STANNARD QUESTIONS

Q. The problem of consciousness.
A. How can your basic building blocks that are electrons, neutrons and protons combine to form atoms; atoms that combine to form molecules; molecules that combine to form complex molecules - complex molecules like organic molecules, biochemical molecules and molecules part and parcel of neurochemistry; the ultimate result being that this chain from the simple to the complex crosses a threshold from the inanimate to the animate and from the animate to the animate entity that is self-aware. It is a profound mystery why one has a fairly unique structure comprised of the same fundamental bits and pieces that comprise all other structures but yet one that can contemplate itself. That structure is the brain and the mind that resides within that structure. The brain is the only structure in the cosmos that can examine itself and yet that structure is ultimately comprised of just electrons, neutrons and protons. However, is there really a problem if that structure can ultimate figure out how to create another structure that also has consciousness. In other words, intelligent and conscious biological software can deliberately give rise to an artificial intelligent and conscious string of software and in doing so thus create a Simulated [Virtual Reality] Universe that houses or contains an apparent (but artificially) intelligent and conscious biological entity or entities that wonders whether or not there was an artificially intelligent software program that gave rise to it. That sort of reminds me of the human who dreamed she was a butterfly who dreamed it was a human, or was that the butterfly who dreamed it was a human who dreamed she was a butterfly.
  
Q. The free will/determinism problem.
A. I tend to have a belief in absolute causality, much like both Newton and Einstein who believed in a regular clockwork universe. If X happens, Y follows. All the laws, principles and relationships of the natural universe were forged at the time of the Big Bang event and once that clock was set in motion, all else flowed from those first established laws, principles and relationships. So, in other words, determinism rules, okay? That equally holds true if we’re in a Simulated (Virtual Reality) Universe, regardless if we are, like a character in a video game a ‘puppet-on-a-string’ or the avatar as a stand-in in a simulated world for someone in the really real world, or as the consequence of someone programing a set of laws, principles and relationships then hitting ‘run program’ and standing back to see what eventuates. We’d all like to think we have free will, but if we are programmed to believe that, what harm has been done if you really do believe that what you had for dinner was something you freely did choose to have.

Q. How close to the instant of the Big Bang are we likely to be able to probe?
A. We can currently probe or observe no farther back than 380,000 years post Big Bang because the cosmos was too opaque from the point of the Big Bang to roughly that point in time, 380,000 years into the post Big Bang era. However, gravity waves from the Big Bang event could take us to Ground Zero in theory. The problem is in the detection of gravity waves – in theory yes; in terms of actual observation (to date), no. Of course that hasn’t stopped theorists from going back to even less than nanoseconds post Big Bang by running the expanding universe film backwards to the greatest extreme possible, thus postulating and assuming a quantum sized object was at the heart of the Big Bang. Theorists have extrapolated back way beyond what is reasonable or even logical IMHO given so many unknowns. Theory should cease where currently observations cease – 380,000 post Big Bang.  

Q. Can we be sure that inflation took place?
A. No, because we weren’t there! Seriously, we have no direct observational evidence of inflation, only indirect evidence that a theory or theories of inflation can explain some observations (or lack of observations, like where are the monopoles). This reminds me of those epicycles once postulated to explain observations related to the motions of the planets in the night skies. Those epicycles eventually bit the dust; inflation might too. 

Q. If so, how are we to choose which type of inflation it was?
A. Pick a card, any card! Whatever theory of inflation best matches the observations and best conforms to what is known about the laws, relationships and principles of physics goes to the head of the class. 

Q. Was there a singularity at the instant of the Big Bang?
A. No, there was no singularity associated with the Big Bang event. A singularity in common usage by physicists implies a region of space that has zero volume and infinite density. Sometimes I think these eggheads need to observe the real world where volumes and densities are finite. In any event, the density at the point in existing space where the Big Bang happened had to be less than that of a Black Hole, otherwise there would be no ‘bang’. That in turn implies the Big Bang was a macro event, something that happened way outside the realm of quantum physics.   

Q. Does it make sense to enquire into the cause of the Big Bang?
A. Yes, absolutely! There had to have been a cause, physical or software, and it is quite legit to ask what that cause was and try to answer the question. Of course I never said that would be easy.

Q. Why is there something rather than nothing?
A. If there was nothing rather than something you wouldn’t be here to ask the question! So perhaps the fact that there is something is another case of fine-tuning! Something could be a natural condition that’s part and parcel of any conceivable universe or something could be simulated, the simulation of course arising because something existed on up the line that created the simulation. It could be a case of fine-tuning in that universes than consisted of nothing couldn’t give rise or evolve into a something that could ask the question; only a universe that consisted of a something could evolve something that wondered why there was something rather than nothing.

Q. Where do the laws of nature come from?
A. It’s hard in our ordered cosmos to imagine anything but regularity, so the better question might be where do the irregularities, the violations to those laws of nature come from. When they happen we call them miracles or anomalies or if you’re a professional skeptic, pseudoscience (except those “Twilight Zone” anomalies in quantum physics of course – that’s science). Of course anomalies might be a reflection of our not understanding the laws of nature well enough. Or, violations might be due to intelligence. Intelligence is unpredictable, and often has a quirky sense of humor. So intelligence might be behind those exceptions to the rule, so if you see or experience an exception, an anomaly, think intelligence, and if it can’t be human intelligence in the here-and-now, think Supreme Programmer.  

Q. Can one prove mathematically that science will be forever incomplete?
A. I don’t know about a mathematical proof, but science cannot ever be complete if for no other reason than there is always something over that next hill which we haven’t seen and explored yet. Further, there are just some restrictions on what we can know about, like the fact that there is probably more to the Universe than just the observable Universe, since what we observe or cannot yet observe is related to and by the speed of light. If light from Object X hasn’t had time to reach us yet, will science can’t yet deal with the nature of Object X. The same philosophy applies to say the Heisenberg Uncertainty Principle, whereby, through no fault of our own, the very act of observing something changes the properties of that something. Other parts of the cosmos might forever be inaccessible to our sciences, like say exploring the insides of a Black Hole. One could explore the inside of a Black Hole but forever be forbidden from getting the nitty-gritty scientific details of what they found out to a wider peer-reviewed audience.

Q. What is the status of mathematics?
A. Mathematics has no status outside of the human mind. Mathematics is an invention of the human mind (since I know of no other life form that makes use of mathematics in any abstract sort of way) to assist humans in dealing with the many (also invented) complexities of human society (like trade, commerce and economics). Mathematics provides practical applications like navigation and provides ordering and predictability in the natural world that rule the human roost. Mathematics is a not-thing since it has no physical properties and cannot be detected via any of your sensory apparatus. Of course if we’re in a Simulated (Virtual Reality) Universe then we totally exist as, and in, a mathematical construct.

Quantum Physics and Virtual Reality: Part Two

Most physicists don’t have much of a philosophical streak. Most philosophers don’t usually have the technical background to come to terms with modern physics. Whether physicists or philosophers, they don’t promote ideas far outside their subject’s standard model. It’s not usually considered a wise career move. I have no academic career to damage, so I’m going to combine physics and philosophy and think way outside of the established box. It’s going to be physics ‘explained’ by appeal to the Simulated (Virtual reality) Universe scenario.

Continued now from Part One…

# ALL THINGS [NOT] TRANSPARENT

The standard macro analogy to an atom (nucleus and electron cloud surrounding it) is trying to picture a gnat (the nucleus) in the middle of Westminster Abbey with a cloud of bacteria (the electrons) around the walls, ceiling and floor and thus surrounding the gnat. In other words, there’s a hell of a lot of empty space inside your everyday atom. That might suggest that electromagnetic radiation, photons, would have no trouble in passing right on through an atom without intersecting anything and thus being hindered on its uninterrupted journey.

So why isn’t everything transparent? Why doesn’t light go right through you? Why are some things transparent (air, glass) and some things (of equal density and thickness) opaque for a specific wavelength/frequency of ‘light’ (light here being not just visible light but infrared light and radio light and microwave light, etc. not that the energy value of the photons of ‘light’ should matter since it is traveling through what’s for all practical purposes ‘empty’ space). Further, photons have no electric charge properties that would hinder their passing straight through your average atom. 

A quick anomalous point – light passes through air. You can look clear through roughly 100 miles of atmosphere and see the sun and moon and stars, etc. Add a bit of smog or fog and things get a bit on the opaque side, yet the overall thickness and density of the clear air, or air-smog mix, isn’t drastically different. It’s still 99.99% empty space. Something’s screwy somewhere unless of course there’s additional programming that counters the scenario.

# SYMMETRY & PARITY

One of the fundamental bedrocks beloved by physicists is their love of symmetry, especially with respect to time, charge and parity.

Physics should work as we know it whether time is considered positive or negative***. It doesn’t matter if you go 50 miles per negative hour for 10 negative hours, you still travel 500 miles. Or, imagine two electrons (call them A and B) traveling towards in time, each approaching the other. When they get close enough, they will repel each other (both being of the same negative charge) by exchanging a virtual photon. But which electron emitted the virtual photon? It might have been A to B forward in time, but it is just as probable that it might have been B to A backwards in time. It’s symmetrical either way you care to look at it. And of course any negative time that’s squared in any equation reverts to positive time.

Physics and chemistry should work as we know it even if positrons (antimatter electrons) ‘orbited’ around nuclei comprised of antiprotons and antineutrons (collectively anti-nucleons). So charge is symmetric.

Parity is your left-right mirror image. Physics should remain the same when viewed in a mirror. Mirror light still comes out of a mirror image flashlight; gravity still makes mirror image apples fall to the mirror image ground. The distinction between left and right should hold no sway in physics. Unfortunately, while charge and time are totally symmetrical with respect to the operations in physics, there’s an ‘oops’ in parity. The ‘oops’ is not in electromagnetism, nor in gravity, nor in the strong nuclear force (which hold the nucleons (protons and neutrons) in a tight embrace in the nucleus. Parity however is not conserved in weak nuclear force interactions. Physicists might say that Mother Nature has a slight bias towards the left; some theologians might suggest that God is a weak lefthander; I might put it that our Supreme Programmer introduced into some software subroutines a code favoring a slight left-handed slant.   

So 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!

# UNIQUENESS

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 this should be so is not readily apparent from first principles on up the line. However, it’s easy to code any particle, and whenever that code appears, you have an identical particle appear.  

# CHEMISTRY

It’s not at all clear (to me at least), how the rather limited properties we associate with electrons, neutrons and protons, can, just by changing their relative numbers in association with each other, morph into all of the wide variety of properties associated with the chemical elements.

Further, it’s not at all clear (to me at least), how the properties of the chemical elements can ‘combine’ to form molecules with vastly differing properties from those of its parents. For example, a yellowish and to us poisonous gas (chlorine), plus an explosive (in water) silver metal (sodium) can morph into properties we associate with a whitish quasi-translucent solid crystal - table salt (sodium chloride).

Further again, it’s not at all clear (to me at least), how memory and creativity (and not just in humans) can be stored and manipulated in terms of chemistry, organic chemistry, biochemistry or neurochemistry. Of course it’s easy to encode ‘memory’ into software and with the rise and rise of artificial intelligence, can creativity be far behind?

# FRACTAL COSMOLOGY

Though bordering on the fringe, some bona-fide astronomers strongly suggest from both the observational and the theoretical point of view 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. 

# CONCLUSIONS

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”. 

To his dying day, Einstein insisted that there were hidden variables that would, when discovered account for those various quantum anomalies – quantum magic. Those hidden variables would ultimately unite quantum physics with classical physics. Unfortunately for Einstein, experiments have since ‘proved’ that there are no hidden variables of the type Einstein had in mind. That’s because IMHO the hidden variable, which Einstein couldn’t have envisioned in even his wildest imagination, is the Supreme Programmer who creates our Simulated (Virtual Reality) Universe. 

Not only can the Simulated (Virtual Reality) Universe scenario account for the above hardcore but seemingly magical anomalies in physics (and chemistry), but perhaps the Supreme Programmer left us these clues, inadvertently or deliberately, such as, in the macro world, those enigmatic crop ‘circles’ for which no other theory makes any absolute sense, common or otherwise.

***Not to be confused with the concept of running a film backwards.

Those Oops In Physics: Part Two

Some physical scientists – professional skeptics – are quick to jump on what in their opinion are the flaws inherent in what they term pseudoscience or the paranormal. Perhaps they should gaze at their own navels first before criticizing others, as the following hopefully points out.

Continued now from yesterday’s blog…

Oops in Causality     

Causality (the future is contained in the past), cause-and-effect, has to operate across the board if Mother Nature is to be predictable, and prediction and predictability is at the heart of what makes science, science. Yet, some scientists insist some phenomena have no causality. Lack of causality implies that what happens is the result of some sort of ‘free will’ (or variations thereof) which is absurd. That would imply that an electron or a radioactive uranium atom has an independent ‘mind’ of its own. Lack of causality alone in IMHO is nearly sufficient evidence to justify the hypothesis that we are ‘living’ in a simulated (virtual reality) universe.

# Big Bang: Apparently the creation of the Universe (the Big Bang event) happened for absolutely no rhyme or reason at all. That means there was no first cause attributable for the effect that was Big Bang event. Does that strike anyone besides me as odd, as in absolutely impossible?

# Radioactivity: That two identical radioactive (unstable) nuclei will decay (go poof) at different times despite both being in the same place, in the same environment, at the same time. That’s therefore because of the ‘fact’ that an unstable radioactive nucleus will go poof for absolutely no reason at all. If there is no causality behind radioactive decay, then obviously any two identical radioactive nuclei can go poof in a totally random way. But random events shouldn’t result in a precise mathematical relationship, which is what is claimed by observation – the concept of the half-life.

# Electrons: That an electron will drop to a lower energy level by emitting a photon for absolutely no reason at all is strange given that an electron will jump to a higher energy level by absorbing a photon’s worth of energy. There’s no causality in the downward direction; there’s causality in the upwards direction. That’s nuts!  

# 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. That’s crazy, but it happens as you can verify for yourself. 

Oops in Probability     

# Electric Charge: The electric charge of the proton is exactly equal and opposite to the electric charge on the electron, despite the proton being nearly 2000 times more massive. There’s no set in concrete theoretical reason why this should be so.

# Fine Tuning: In fact, you tend to a violation in probability when it comes to numerous examples of fine-tuning – the fine-tuning that allows the Universe to be bio-friendly. For example, if the force of gravity were slightly stronger, the Universe would have re-collapsed into a Big Crunch rather quickly, and thus there would have been no time allowed for life to form and evolve. If the force of gravity had been slightly weaker stars and galaxies wouldn’t have formed. No stars and galaxies: thus, again, a lifeless Universe.       

Oops in Theory vs. Observation

# 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.

# Vacuum Energy: Theory suggests a certain value for the vacuum energy. Experimental observation shows quite a different value for the vacuum energy. In fact, the difference between theory and observation is 120 orders of magnitude. Something is definitely screwy somewhere.

# Protons: Some theories suggest that like an isolated neutron, the proton is, over the long term, unstable and should go poof and decay. Alas, experiments, and there have been many of them, have failed to detect even one proton decay event. Oh well, back to the drawing board.

General Oops: WTF?

# Inflation: In addition to the above, the Big Bang event as a standalone event raised lots of problems, collectively known as the flatness problem; the horizon problem; and the monopole problem. To resolve those issues, a secondary theoretical and rather ad hoc expansion event, termed Inflation, was proposed. Alas, it lacks any shred of actual independent and observational evidence (apart from dealing with the Big Bang issues as noted), and has its own set of problems, not least of which there are many variations on the Inflation theme; how and why Inflation started and how and why Inflation stopped. If the Big Bang were really a comprehensive theory of everything with respect to the origin and early evolution of the cosmos, there wouldn’t be a horizon, flatness and monopole problem requiring an ad hoc tack-on.

# Dark Matter: There apparently isn’t enough mass contained within our galaxy (and others as well) to account for its structure and how it stays together as a collective conglomerate of stars, planets, interstellar dust, etc. So, with a wave of a magic physics wand, physicists and astrophysicists invent out of thin air an ad hoc explanation – all that missing matter must be “dark matter”, matter which we can’t see, can’t detect, and haven’t a real clue as to what it might be

# Cosmic Rays: Cosmic rays tend to be very high energy particles like electrons and positrons, protons and antiprotons, alpha particles and other atomic nuclei that originate from beyond our solar system. After that, things get iffy. Their actual point(s) of origin are anywhere and everywhere and to be honest their origin(s) are rather mysterious. You name the astronomical object and someone will have tagged it as a, if not the, source of cosmic rays. Among the candidates are supernovae, active galactic nuclei, magnetic variable stars, quasars, gamma-ray bursts, even the Crab Nebula (a pulsar) and the radio galaxy Centaurus A. It all seems to be a case of picking a number out of a hat or throwing a dart at a dartboard labeled with astronomical structures. Your guess (and that’s what they are) is as good as mine.

# The Fine Structure Constant: The mysticism over the number 137 (i.e. - actually 1/137) – the Fine Structure Constant – has the same sort of cultist fascination and impact on some physicists and the physics community in general as the dimensions and mathematical relationships and their significance inherent in the Great Pyramid (at Giza, Cairo) has to occultists, numerologists, mystics and pseudo-archaeologists. Then there’s all that endless numerological speculations on and significance of 666 to Christians. A rose by any other name applies here.

Conclusions

As we have seen, there are many ghosts that haunt the academic corridors of academic physics. Physicists need to exorcise those demonic spirits first, before trying to inflict their exorcisms on the rest of the irrational world.


* What can escape from a Black Hole is called Hawking radiation, but in that massive a Black Hole, the one required for a pinhead sized start to the cosmos, that radiation leakage would take a very, very, very long time to ooze out; hardly what you’d call an explosive event.
