It is interesting to learn about the Universe. If you take higher level astrophysics classes you learn that the Universe actually has a critical density (Im pretty sure this was the term used). You see gravitational forces act on mass. The Universe has a mass, and it has an aggregate density as well. When a star goes into nova(?), you have it expanding because the outward pressure from the explosion is greater than the gravity. This fluctuates and so it expands and fission(maybe fussion, im not a major in this) takes place. Now the matter is denser and the gravity increases thus it contracts again. This happens over and over until it finally explodes. The Universe is like this. Scientists have tried to estimate the critical density of the Universe so that we can determine something very important: will it continue to expand for ever in at "constant" rate, will it exponentially expand and eventually "hyperexpand" upon itself, or will it simply hit its maximum and recollapse? This is quite interesting as it leads us to understand the geometry of space. I think that Hubbles Law is somewhat used to calculate this rate, and of course vector calculus is used as well. The strange thing is that the geometry is much different; I think its non-euclidean geometry. Anywho, im probably making people get headaches now, so ill stop, but this is in fact some interesting shit.
Yay! It's BWS my knowledge hero!
A star will throw all of its matter outward when it is about to die in an attempt to save itself from pressure and heat, but it will eventually just go nova on its ass.
It wouldn't make sense for "our" universe to keep expanding into hyperspace for eternity, because you can connect that to the spiritual aspect that nothing lasts forever. The way I think about it is that you can connect things through the mind, spirit and body. So a great inner lesson will also teach you about physics. It sucks that I have such a shitty math teacher or else I would get more into it, which would help out my astronomy.
I think we should look at our universe on a much larger scale, in the sense that our universe is only a tiny blip in time compared to the whole picture, it's just we percieve normal time at a steady pace, kind of like Terra being the right distance away for all three forms of water to exist on "our" planet.
I also like to look at our solar systen as just a normal particle of energy floating about, until it meets another atom and fuses with that. And that our different dimensions collide when everything is connected. It's like in Animal House when they smoke weed and the professor projects the idea that the atoms in our body are merely universes, but we percieve them as atoms.
When you think about it we are only made of electricity and chemicals, so it is possible that there is other life on every other planet, even the sun, but our understanding of life is only how we are and not how the chemicals are placed on the other planets. We just can't percieve the electricity and chemical reaction on other planets.
But this is all just me talking, only a man.
