Those Oops In Physics: Part One

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.

Some people for example claim that some UFOs are actually extraterrestrial spacecraft and get bucketed for their point of view. No evidence; no proof is the mantra of the skeptic – usually a physical scientist. However, IMHO, some physicists (or other equivalent physical scientists like astronomers) make even greater outrageous claims without a shred of evidence, far less proof. The attitude of some scientists seems to be along the lines of ‘do as I say, not as I do’.

Physics tends to be a subject that lots of ordinary folks shy away from, probably because physics tends to rely heavily on mathematics, and usually highly complex mathematics at that, advanced mathematics that aren’t taught until well into third or fourth year at university and into gradate school. However, even when modern physics is explained minus the mathematics, in what I guess would be termed layman’s language, physics turns out to be really, really weird. The mathematics tends to hide the weirdness from the uninitiated (since everything is double Dutch to them) but it’s there all the same. These are some of the examples I’ve come up against – a wall that one tends to bang one’s head against in frustration. The frustration tending to be in the first instance, what’s wrong with me that I can’t do an end run around the (only apparent) weirdness? Once one accepts that it’s not you, but the physics that’s weird, well that doesn’t eliminate the frustration or the feeling that one still needs to bang their heads against the wall! Of course maybe it’s not the physics that are weird but the physicists. It wouldn’t be the first time – but that’s another story.

Oops in Common Sense - Theory

Now I am aware that common sense is not an acceptable criterion in science, but there is a limit to what pills I will swallow. With the exceptions of the speed of light and neutron decay (see below under observations) there is no observational or experimental evidence for any of this theoretical nonsense.

# Point Particles: Particle physicists often use the term “point particles” when talking about the fundamental or elementary particles that make up matter, like electrons, etc. However, a point particle has zero dimensions, and as such takes up zero volume. The upshot is, if particles have no dimensionality, then matter cannot exist. Matter is made up of these elementary particles, and if each particle has zero volume, well zero plus zero plus zero equals zero. All of matter would have zero volume and that’s clearly not the case. Alternatively, point particles couldn’t smash together in say the Large Hadron Collider or in any other particle accelerator.

# Dimensions: That there are up to ten spatial dimensions (not three) if Superstring Theory or M-Theory is correct. In the words of the late physicist Wolfgang Pauli, that’s “not even wrong”. 

# Big Bang: That the first nanosecond of creation crammed the contents of our observable Universe into a volume less than a pinhead. In any event, if you could squeeze the contents of the observable Universe down into a pinhead’s volume, you’d end up with the Mother of all Black Holes from which nothing* would escape. Therefore there would be no Big Bang and thus our Universe would not have been brought into existence. 

# Big Bang: That the Big Bang event created time itself. This can’t even be done in theory, far less in actual practice. Pull the left leg!

# Big Bang: That the Big Bang event created space itself. This too is beyond the theoretical limits of modern physics and certainly cannot be duplicated in the laboratory. Now pull the right leg!

# Theory of Everything (TOE): There are three quantum (micro) forces that rule the roost – the strong nuclear; the weak nuclear; and electromagnetism. All three have been unified into the Standard Model of particle physics that’s called the Grand Unified Theory (GUT). There is also one force that rules that rules supreme in the classical (macro) world – gravity. Since the micro and the macro are both part of the larger picture – Mother Nature – it should seem obvious that gravity can and should be unified with the Standard Model to provide what’s known in the trade as a Theory of Everything (TOE). Alas, despite the best minds working on unification over many, many decades, nothing of substance has surfaced. The realm of the micro and the realm of the macro are incompatible, like two different sets of software that are separate and apart but collectively run the cosmos. That makes no sense. It should be relatively easy to unify all four forces.    

# Gravity: Centuries after Isaac Newton, the puzzlement that is gravity has still not been completely solved. There appears to be two competing theories. One, gravity is geometry, otherwise wrapped around Einstein’s General Theory of Relativity. Mass tells space how to curve; curved space tells mass how to move. Two, gravity is a force somewhat akin to electromagnetism in that it has an associated particle that conveys the gravitational force, like a photon conveys the electromagnetic force. That hypothetical or theoretical particle is termed the graviton, and remains to date undetected. You’d think by now the issue would have been settled. 

# Observation/Measurement: That the lack of observation or of measurement (same difference) has a bearing on the reality of what’s not being observed or not being measured is absurd. That’s like saying the Moon doesn’t exist, or may or may not exist, or exists and yet doesn’t exist at the same time, if nobody is looking at it. In any event, to but the worms back into that can, during the early history of our Universe, there were no observers (i.e. – no life forms of any kind) and the cosmos got along just hunky-dory. The Universe doesn’t give a rat’s ass about observers. Things either are, or they are not.

# Electrons: 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.

Oops in Common Sense - Observations  

# Velocities: Velocities maybe added or subtracted. If you are on a treadmill that’s moving left at 5 MPH, and you’re on it walking to the right at 5 MPH, to an external observer you are waking yet standing still. Now the exception to that universal rule is the speed of light. The velocity of light is a constant to an external observer no matter what. Why that should be no one knows, but it is so. However, my take on this can of worms which as a consequence require both time and length to be flexible, is one should always be a bit suspect when it comes to the lone ranger, the exception to the rule. There’s something weird afoot here.  

# Neutron Decay: One isolated neutron will decay in roughly 15 minutes into an electron, a proton and an antineutrino. That’s probably why a hydrogen atom hasn’t a neutron you’d think; there’s only one electron around a nucleus of one proton. Unfortunately heavy hydrogen is heavy because it has one neutron, so that blows that idea. Apparently therefore, any neutron inside or part of a nucleus is stable. So obviously two or more neutrons together (i.e. – part of a nucleus or within a neutron star) will not decay. Why one isolated neutron is unstable, yet a neutron or neutrons (two or more together) as part of a nucleus or as a neutron star are stable, is to me a mystery that defies logic. I mean, by analogy, an isolated radioactive (unstable) nucleus behaves no differently than its clone or twin that is cheek-by-jowl with others of its kind. 

Oops in Conservation Laws – The Free Lunch     

# Dark Energy: Apparently the density of Dark Energy remains constant while the volume of the Universe expands. That’s something from nothing. That’s a free lunch.

# Big Bang: 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 also a free lunch.

To be continued…
