Dear Jan Pantelje:

(sorry to talk over your shoulder George)

No problem David, it's a public group.

It can also be considered rude, that is why the preface.

Why does light appear to redshift when being produced in
a place with higher gravity (curvature)? Doesn't curvature
produce "gravitational time dilation"? Wouldn't a younger,
more dense Universe have higher curvature than at a later
time? c doesn't have to change to get redshift.

If V(x,y,z,t) is the gravitational potential at some
event, then it is obvious that partial dV/dx is zero
everywhere for a homogenous, isotropic universe (over
large scales) and similarly for y and z, but what can
you say about partial dV/dt in say an FRW universe?

I would guess.. the spatial relations simply require that the
redshift (if any) be specular. And dV/dt should be non-zero
also, but Bjoern is the only FRW expert I have come across.

Does the question mean anything anyway or is it "not
even wrong"?

I think it is redshift, but let's see if Bjoern is lurking...
