- Re: G.F.R. Ellis's speculation that the Universe is small and we've
- already seen around it many times:
-
- I understand that Ellis is considering some kind of nontrivial
- topology (though I don't understand the topology!). Can one
- of you speculate on what this would do to the volume element as
- a function of r? It seems to me that this is one of the stronger
- observational tests of such a notion (e.g. in the conventional
- topologies the observed volume element limits the curvature to
- be fairly close to flat, otherwise things would happen with galaxy
- counts that we don't in fact see.)
