- Regarding the speculation by G. Ellis that we are seeing the same galaxies
- multiple times due to light going around the universe more than once :
-
- Isn't there a result from General Relativity that holds that a photon can
- travel around the universe at most once before the universe collapses
- again ? (The version without the cosmological constant). So, if this is
- observed, does this kill off standard G.R. ?
