Center of the Universe?
I don't know much about cosmology, but I just went to a talk that presented the current knowledge about the big bang and I had a question that I didn't get to ask because of the time constraints, so here it is.
The Hubble red shift data was presented as evidence that the universe is expanding in every direction with a velocity that increases the farther away you look. This implies that the universe was denser and hotter in the past. My question is, can you use the rate at which the velocity changes in different directions to find an area that it is all expanding away from?
In other words wouldn't the velocity be increasing quicker (as a function of distance) along a direction pointing away from the center than it would along the direction pointing towards the center?
