I was thinking about an alternate explanation of red shift of distant stars: Infinite universe would have 0 average gravity by symmetry.

We only see the near side of distant galaxy clusters contracting towards their centers away from us. Light from far side (which would be blue shifted) is relatively blocked by the near side.

Farther away objects need to be brighter for us to see them directly. Which means they are further along in their contraction, which makes them move faster, increasing red shift.

So , can we get rid of the Big Bang theory, dark matter, and dark energy ?
