Just so you know...i just got out of high school, so my understand of physics is limited to say the least, but I have read that Einstein's theories of relativity predicted the expanding universe, here is what I imagine and tell me if this makes logical sense.
Ok we're 3d objects in a universe with 4 spatial dimensions. So I imagine us as dots on the surface of a sphere with an even grid on it representing the spatial fabric. Then I put all the mass (dots) at the top. This mass stretches the spatial fabric up towards it, so now what you have is a sphere with a bunch of lines at the top and close to non at the bottom. This represents space just before the big bang. Now what happens, because space is so stretched, the universe (by some force i guess) goes to correct this by the sphere blowing up like a balloon, as it does this all the dots spread out rapidly and the energy and heat dissapate and the lines (spatial fabric) even out and become uniform, which has not happened fully yet.
However I don't think this is accurate because if the lines evened out...there would be no more gravitational pull right? and I'm not even sure that if the balloon were to expand the lines would become even...i don't think they would...they would all stay the same distance from each other in proportion to each other, right? I don't know why but I thought that the warping of space and time by mass caused the universe to expand in an effort to correct the warps in the spatial fabric, but I don't think that is correct...
I'd just like to hear your opinions on this and explain, in a non mathematical way, if that's possible, how Einstein's theories predict the expanding universe.
Thanks, Zach
