I just don’t get it.
According to the theory of special relativity, nothing can ever move faster than light speed.
But due to the expansion of the universe, sufficiently distant stars move away from us faster than the speed of light.
And the explanation is…that this universal speed limit doesn’t apply to things that are really far away?
Please make it make sense!
Objects beyond our cosmic event horizon are in a similar state to objects inside a black hole’s event horizon: we can describe them in hypothetical terms, but they’re effectively outside of our universe. There’s no longer any causal connection between us and them in either direction, and our relativistic frame of reference doesn’t extend to them.
