When we look out into the universe, far beyond the edges of our own Local Group of galaxies, we see objects?

Question

a. we are at the exact center of the expanding universe.

b. absorbing matter is distributed uniformly throughout the universe, which limits our view of the expansion.

c. the expansion must be the same everywhere in the universe, since we are not likely to be at the exact center of the universe.

Answer 1

C.

As late as 1900, there were people who believed that we were at the center of the Universe (the Milky Way).  There was plenty of spectrographic evidence that galaxies weren't made of gas, but rather stars.  If they were stars, and so faint, they had to be really far away - outside the Milky Way.  But it took Edwin Hubble's variable star, resolved in the Andromeda Galaxy, with his half million light year estimate of distance before people really started to get it.

Why not ask this in Astronomy and Space?
