[PhysBang]

I can't even source this, but I have heard that the Universe is going through another period of inflation. How does the speed of light slowing from the start of the Big Bang allow for this?

One can account for the apparent acceleration of the expansion of the universe by, in effect, assigning a force that works counter to gravity at large distances. The effect of this force over time can be used to distinguish between a constant force and one that varies. If the force varies in a certain way, it may be the same force that caused inflation in the early universe.

I'd have to think a bit on the exact effect of slowing light. it's somewhat complicated.

Phys,

Early Galactic Inflation is described as a 'scalar field'. Mostly its a convenient terminology to explain the inexplanable.  A scalar field, I believe, is simply a phenomena that has a limited geographic or time limit after which it is expended.

IMHO, the current 'increased velocity of expansion' could very well be just one more of these scalar fields that will simply run its course and stop.

OK, what is the maximum red shift?  The Htz of a photon is reduced by expansion. At what point does the expansion reduce a photon to near zero Htz?  At that speed of expansion, the photon might have a velocity of C, but a propogation of zero.
