More Anomalies: Another Top Baker’s Dozen: Part One

From the cosmic to the quantum; from the macro to the micro; from the natural world to the human world, enigmas are everywhere. Here’s another baker’s dozen worth.

You may not be happy with the world as it is, but at least it’s orderly and makes logical sense. Walk, don’t walk, green yellow red; money trickles in, money flows out; friends and politicians come and go, enemies and stuff accumulate; the sun rises and sets, the moon waxes and wanes; people are born, people die; the days, weeks, months, seasons. and years come and go with regularity. But dig a bit deeper beneath the surface and the world and the cosmos it inhabits, is one anomalous place.

THE BIG BANG EVENT: This is no doubt a concept that nearly everyone has heard about, and swallowed hook, line and cosmological sinker because scientists present this creation of the Universe scenario as fact. It’s not fact; just the most viable theory of many theories and it has serious flaws. The accepted theoretical account of the creation or event that kick-started our Universe off not only has that event a something that created all of matter and energy, but all of time and space as well, and this creation event, to boot, all took place in a volume less than that of a pinhead (something in the realm of the quantum) and for no apparent reason at all. First there was nothing; then there was something. Wow!

At best observations that support this are indirect being made some 13.7 billion years after-the-fact. Those indirect observations that provide evidence for the Big Bang event are the fact that the Universe is expanding; the Universe has a temperature – the remnants from the hot Big Bang called the cosmic microwave background radiation (CMBR) and the amounts and ratio of hydrogen to helium. In reality there are no direct observations as nobody was present at Ground Zero all those billions of years ago.

There are really a couple of anomalies present in the standard Big Bang account. 1) You have a violation of causality – something (space, time, matter and energy) created from nothing which is a violation of several conservation laws or relationships. 2) You have a violation of pure common sense that tells you that you can not stuff the contents of the entire Universe into the realm of the quantum, something actually way less in volume in fact than a pinhead. If that’s not anomalous, I don’t know what is!

SPEED OF LIGHT: The anomaly here is that in any other scenario, velocities can be added and subtracted, except the velocity that’s known as the speed of light. Within Relativity Theory, if there is anything unintuitive it is the fact that in the entire Universe, it is the speed of light alone that is absolute or fixed, not something like space or time. It’s unintuitive in that all other bits and pieces that are in motion can be added or subtracted. So, if you are in a train that is moving at say 100 km/hour and you throw a ball at 10 km/hour in the direction at which the train is moving, to an observer outside the train, your ball is travelling at 110 km/hour. If you throw the ball towards the rear of the train, an outside observer will measure the ball as moving at 90 km/hour. If on the other hand, you shine a flashlight in the train, an outside observer will see the velocity of the resulting light beam moving at the speed of light – not the speed of light PLUS the velocity of the train, or the speed of light MINUS the velocity of the train, but at the speed of light! That’s nuts, but it’s scientifically nuts and been proven again and again in any experiment you care to devise.

QUANTUM GRAVITY AND THE THEORY OF EVERYTHING: We have the Theory of General Relativity (gravity) and Quantum Physics. Both are bedrocks of modern physics. Both are accurate to a high degree of experimental precision. Both aren’t compatible - with each other. Apparently, one (or both) of these theories must be wrong, or at best incomplete. That’s why the unification of the two (a theory of quantum gravity) is physics’ Holy Grail. However, that Holy Grail is proving as difficult to find as the Biblical Grail itself! But for the moment, it’s like the universe has two independent sets of laws – one governing the very large (gravity); one the very small (the quantum). This makes no natural or scientific sense.

We have observations of four physical forces yet no theory which unites the three quantum forces (electromagnetism, the strong nuclear force and the weak nuclear force) with the one classical force – gravity. Theory needs to be satisfied. All of the four fundamental forces should be interconnected; some sort of unification principle must be in operation that relates all four, one to the other. However, these four fundamental forces that govern the Universe show no signs of any obvious unification – well actually the three quantum ones do (known as the GUT – Grand Unified Theory), but that’s where the unification ends. Gravity remains the wallflower. If the Big Bang theory is to be proven correct as stated, scientists must of necessity come up with a viable theory of quantum gravity that is an acceptable unification of the trio of quantum forces with gravity. There is, to date, no viable theory of quantum gravity despite thousands of physicists searching for one over many generations now. Mother Nature is an anomalous bitch!

QUASARS: Quasars are ‘quasi-stellar objects’. They are ‘stellar’ because they aren’t all that large (like a galaxy). They are ‘quasi’ because they give off energy way, way, way more times greater than any star known in any astronomical catalogue. They seem to be primordial objects – they formed long ago and are now far away.  Quasars, like stars or galaxies, are their own entities and if two or more show a very close and special causality relationships then they should show identical recessional velocities (since the Universe is expanding and they are part of the Universe and that expansion). Recessional velocities are measured by an object’s red-shift. Theory identifies red-shift with velocity. However, you apparently have some observations of causality connected quasar pairs with vastly differing red-shifts (measurements of their recessional velocities). The anomaly, in an analogy, is that you can not have a runner running at 15 miles per hour holding hands with another runner running at 3 miles per hour!

MASS: There are three fundamental properties of particles (like the electron, neutrinos, the numerous quarks, etc.) and their anti-particles (like the positron). They are charge, spin and mass. As the song goes, two out of three ain’t bad, but that still leaves one out of three out of joint. In this case, it’s mass. Nobody can predict from first principles what the masses of the fundamental particles should be. That’s fairly disturbing for something as fundamental as mass. Despite the relatively large number of particles (including their equal and opposite anti-particles), there are only a few allowed values for charge and spin, values pretty much confined to the physics infield. But, for some reason, the mass (usually expressed in equivalent energy units – Einstein’s famous equation) of the various particles are not only scattered throughout the physics ballpark but are all over the city map and beyond. They take on values (albeit one value per type of particle) over many orders of magnitude without any apparent pattern or regularity or relationship between them – and nobody has the foggiest idea why, not a validly theoretical idea, or even a ‘far out’ idea. Why should mass differ so greatly from the other fundamental properties part and parcel of those elementary particles? It’s like someone just drew a few dozens of numbers out of a hat containing multi hundreds of thousands of values and assigned them to the few dozens of particles willy-nilly. Something is screwy somewhere because something so fundamental shouldn’t be so anomalous.

PHYSICAL CONSTANTS: There are constant reports of physical constants that aren’t – constant that is. Physical constants are just that – a constant. They have just one value, everywhere, every-when, and no exceptions. But apparently some ‘constants’ have more than one value depending of where and/or when. Theory and observations (if correct) are yet again not in harmony and that’s totally nuts!

TIME TRAVEL: Time travel to the past is a staple of science fiction, but surprisingly has actual viability in modern general relativity physics. In general relativity physics, time travel to the past is theoretically possible – though damned difficult in practice. However, that means that those time travel paradoxes are possible, even likely.

The anomaly are those lovable paradoxes like going back in time, say ten years, and killing yourself (which is a novel way of committing suicide), which means you couldn’t have existed to go back in time in the first place in order to kill yourself, which means you’re not dead so you can go back in time and murder yourself, etc. What kind of physics is that?

The second anomaly however is that no time travellers have been observed from our future. You would think various significant historical events would be swarming with historians and tourists from the future where time travel is possible. Nobody from our present or past has time traveled back in time and left a proof-positive calling card that we’ve ever found in the fossil record or recorded in the history books.

If something is possible, especially something as interesting as time travel, we would expect to see either people from our future in the here and now, or evidence that we’ve travelled to the past, like finding a human skeleton buried inside a T-Rex skeleton, as in inside the area where the T-Rex’s abdominal cavity would be! We don’t.

To be continued…
