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.
