I can't find any reference that says it's moving away from us at twice the speed of light, which would violate Relativity. The fact that it is further away from us in light years than the age of the universe in years, is due to the fact that the space itself is expanding.
The thing is, it's moving that fast because of the expansion of space. โ30 billion light-years over โ14 billion years equates to over twice the speed of light. Does that mean there's no crazy relativistic time dilation, and time is moving normally for them in our frame of reference, since they aren't physically moving, it's space that's expanding? That's just as wild to my brain
Relativity only applies to local reference frames and not to the recession rates of cosmologically distant objects.
