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.....? |

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. |

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