General Relativity

The rules are the same everywhere in the universe, but special relativity only applies to things you can see near you. One reason we can measure these galaxies to be moving away from us faster than the speed of light is that they are not in our inertial frame of reference. In fact, the definition of velocity in general relativity is a little bit fuzzy for things that are far away from you. We don't know how to make those comparisons.
