Hi Marsha
If you google Petr Horava and read about his hypothesis (it's about
gravity but this affects C and Time as you'll find) you'll see what's
going on. It's to do with uncoupling Time from Space-Time and Lorentz
Symmetry.
Also, try this link:

it's a bit cheesy but an interesting introduction.
There are also articles about this in both New Scientist and Scientific
American.

Hi Guys
From what my friend was saying, this new ( and I believe it is very new ) idea
about C has completely screwed the old ideas about relativity, special or
otherwise and has, effectively, turned physics on it's head. It looks like it's
as big a change from what we have thought until recently as the change from
Newtonian physics to Quantum physics.
I've emailed him to see if he has any references that I can point you in the
direction of!
I know about most of what's already been mentioned, slowing light down in
different mediums, space stretching but remaining constant locally,
gravitational variance etc. but, if I understood him correctly and he's
normally pretty reliable on this sort of stuff, what he's talking about could
mean that large chunks of physics is just about to be completely re-written!
I'll await his reply and let you know.
Cheers

Hi Marsha
It probably depends on what you mean by a vacuum but I was having an
interesting conversation with a friend of mine yesterday about C.
Apparently, from what I gather he was talking about, C is no longer a
constant but is dependent upon the curvature of space - i.e. if there is
a gravitational difference in one area of the universe compared to
another area (E.g. a singularity) then there will be a difference in the
value of C!
Actually, c will still be constant because even if space is stretched out,
light will still travel so and so many km per second. It's just that a km gets
longer if space is stretched out. So, *locally* (inside the stretched space),
light travels at c, but from a point outside the stretched space, the light
will have travelled faster than c.
