Every now and then I have a weird idea about the universe. Usually I have these ideas while I am trying to get to sleep, so they can be a bit weird. The last idea I had was about the dimensions described by M-Theory. It seemed weird to me there are all these extra dimensions that are there to make the math right. Now I'm not saying that's why they're there. I don't have a background in theoretical physics so I don't know how it really works, and as I write now I am realizing how silly my idea must seem to someone who knows about such things...
So my thought was that all these dimensions, while mathematically elegant does not seem to make much sense. What is the real reason that these dimensions exist? Surely the God that I believe in had some kind of purpose for them that we have not yet figured out. My initial thought was that each of these dimensions has a specific force or action associated with is. I initially started out by thinking that light was a particle in one dimension, and what we saw in our dimension as a wave is the interaction between the two dimensions. I then extended this beyond light to gravity having it's own dimension (a theory which is discredited in the physics community) and the 3 other fundamental forces.
This led me on to thinking about what DOES happens when these dimensions interact. When space and time interact in a basic way we get velocity (distance over time). So what happens when the other dimensions interact? Velocity is an integral part of kinetic energy, so does the dimensional interactions we don't know about produce other types of energy? Is energy conserved within each individual dimension or only as a sum of all dimension? How do these dimensions react in the extreme environment of the Big Bang and during the universes inflation?
Speaking of the beginning of the universe, what happens to matter when it is in such a compressed environment? I have read some excerpts from physicists that theorize on this, mainly at the start of the universe, and that got the brain juices flowing again. I started thinking about a black hole and wondered whether there is a critical mass at which the black hole collapses and becomes something else. By this, I don't mean the point at which a star collapses and becomes a black hole, but rather what a black hole becomes. If we were to extrapolate the universe forward to it's near end, and every star has collapsed into a black hole, and the black holes all converge into a single singularity (if that is even possible), what then becomes of the universe? Could the pressure become so large that it causes a massive release of energy and cause a Big Bang 2?
After considering all this I decided it was far beyond my pay grade to know the answers. If you have any answers to my questions (which I'm sure someone does), please tell me how/why I am wrong. I have no doubt that I am wrong on most of my ideas about theoretical physics as I don't really have much education on the subject apart from a couple subjects at uni, two Stephen Hawking books, and watching all of The Big Bang Theory.
And now my head hurts from thinking too much...
