Some Random Thoughts In Physics
Some Random Thoughts In Physics Sometimes you have a new idea, an idea, or moment, but it is not fair enough to be broader in a reasonable article or article. Therefore, here is a pot of thoughts within the area of Physics it is not too good to record, but there is not enough meat outside the meat.* There’s nothing too controversial about the idea that other universes in a Multiverse could have differing laws, relationships and principles of physics than our own. It’s one way of explaining why our Universe is a Goldilocks Universe. If you have billions and billions of universes each with a unique or differing set of laws, relationships and principles of physics, well probability suggests that one universe should just right for life – a Goldilocks Universe. Since we can only exist inside a Goldilocks Universe, well that explains that. But what if the laws, relationships and principles of physics in our Universe changed over time, or over space, or both! Then it’s probably time to turn out the lights, shut and lock the lab door and go home. It’s time to find a new career. But amazingly, there is (controversial) evidence that that is just that. Physics constants aren’t.
* One of the 64,000 $64,000 questions: Can you pour stuff down a Black Hole indefinitely, or does the Black Hole have a finite capacity and ultimately or eventually will have to spew stuff out the ‘other side’ (i.e. – producing a White Hole) as you keep pouring in more and more and more? I’d wager the conservation relationships and principles of physics and chemistry hold sway here. What goes in ultimately comes out. That doesn’t mean there’s not a temporary holding vessel. Or, in more human terms, you fill what’s empty; you empty what’s full, but in-between those two there’s storage in the stomach and the intestines; the lungs and the bladder.
* Quantum physicist Erwin Schrodinger had a lot of trouble accepting some of the weirder philosophical concepts inherent in quantum physics. Specifically, that something, a fundamental particle like an electron, could both be, and not be, at the same time – in a state of superposition – that was only resolved when an observation or measurement was made. Schrodinger decided to replace the electron with a cat-in-a-box that was in a superposition of states being both dead and alive at the same time, the resolution of either/or decided when an observer actually observed the cat-in-the-box.
However, there are two explanations for gravity if I read the textbooks correctly.
Gravity Is Just Another Force: Firstly, there are in this worldview four fundamental forces: the electromagnetic force, the strong and weak nuclear forces, and gravity. Forces have accompanying elementary particles witch convey the force. In the case of the electromagnetic force, the particle is the photon. The particle associated with gravity has been dubbed the graviton. Unfortunately, it has never (to date) been detected. Now the central issue here is try as they might, physicists cannot unify the four forces into one whole, called a Theory of Everything or TOE**. Since everything should be related to everything else, gravity should be, if not a brother or sister to the other three force-related siblings, at least a kissing cousin. Alas, it’s an unrelated hermit that wants no ancestry with the other three.
We can’t see, or even detect directly, 96% of the Universe! We have no idea what 96% of the Universe is composed of. If that’s not anomalous, I don’t know what is. Both however have revealed themselves indirectly via their gravity (in the case of Dark Matter) or their anti-gravity (in the case of Dark Energy). Some of that ‘missing’ part of the Universe is matter of unknown composition, but like all good matter, has gravity. It’s the gravitational effect on matter we can see that gives the game away. Some more (way more) of that ‘missing’ part of the cosmos is Dark Energy which is that unknown stuff which is accelerating the expansion rate of the Universe and if that’s not anomalous, I don’t know what is since by rights the expansion rate of the Universe should be decelerating under the force of gravity. The fact that it’s accelerating suggests that Dark Energy is a form of anti-gravity, a repulsive force driving things apart at ever faster and faster rates. Although gravity is really out of the accepted physics, there is a balanced parallel with the electromagnetic force, in which both gravity and moderate. Therefore, gross attachments are very high.
