Greg, Happy New Year. One more thought on this subject. First, I
assume we
can observe stars beyond the local galactic cluster. Assuming this,
if
light travels at c only in gravitationally bound systems such as the
local
galactic cluster, is it possible that things we take for certain
locally
do
not apply beyond? For example, could the measured red shift of a
star
beyond the local galactic cluster be "distorted" due to constants
such
as c
not applying across such vast distances? In other words, is it
possible
that the red shift may have been distorted in travelling from one
gravitationally bound system, outside of it, to another, etc?


Happy New Year to you too!

Resolving individual stars beyond the local cluster is
difficult, but individual supernovas can be seen. We can
certainly make out collections of stars, i.e. galaxies.

How do you know they are collections of stars if we can't make them out
individually? Maybe they are just some weird light flashes?

Take a look at some Hubble pics, especially some of the
deep field views.



They show individual stars.....?

No, they show what are unmistakably galaxies. Also,
the form does not change from the very distant to the
very close, where we can make out some individual
stars. We can certainly make out individual stars in
the galaxies of our local cluster, for example.

Globular clusters and quasars.

Who can't make them out individually. Visit Hubblesite.
