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?
