For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some 'organic element' since I couldn't accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

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. โ‰ˆ30 billion light-years over โ‰ˆ14 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.
