3) But that's quite a while in terms of a scientific theory. You would be surprised how many times GTR has been tested and how well it is understood.
4) No, unless you can identify a mass that would create such a huge gravitational field.

1) Relative to everything? If the universe is expanding, and we are not shrinking, thus making the universe expand, then the universe would have to be expanding relative to everything. The question is, is time-space expanding? If so is it expanding relative to everything? This is what I have a hard time believing in.
2) The distant objects would be redshifted more because of distance needed to travel. As we sink into a well all distances are further. Thus making very distant objects further away.
3) The same could also be true about the world being flat and that planets and stars rotating around the earth. How many years was that theory taken as absolute truth.
4) A black hole? , The center of our galaxy, or our galaxy as a whole?, the things that make galaxies move?
