As the universe expands...
Is it that we are more on the surface of a balloon, so the expansion is similar for us as it is for our most distant material counterparts? If this is the case than is gravity a consequence of matter resisting time (since the ?big bang or something?)
As we expand (say, like a balloon) away from the 'beginning' could gravity be the result of something of large mass taking more time to get moving than something of less... thus space/time gets bent around it as the universe accelerates? Then say there are 2 objects, one occupies a large volume at low density, and one with a small volume/ high density but both have the same mass are traveling in space/time... would the large volume object exerts a small force of gravity over a greater amount of space, and the small volume object exerts a great amount of gravity over a smaller amount of space? I know gravity is dependent on 2 things. Mass, distance.
Then if the universe was NOT expanding nor contracting, would there even be gravity? Would matter even be able to sustain itself, or would it diffuse into oblivion? I don't think a static universe is even possible... It has to be in a state of motion to exist. TinyTim explained to me a long time ago that the moon would appear to be getting smaller if gravity was due to acceleration/expansion, but if you place the universe on a plane like the surface of a balloon, does this change? why/why not?
