What seems to be the problem?

 


So the most distant star ever discovered, nicknamed Earendel, might not be a star after all, but a star cluster. And still bloody distant. So what exactly seems to be the problem here? 

Ooops! We have a problem.

Comoving distance



G-d is a funny dude, I mean, for some reason he only cares about some nude chimpo-dimpo cousin on one tiny little planet in the vast 93 billion light year expanse...

Few understand this

Earendel

This kind of stuff makes my head spin. Apparently, astronomers have discovered a super-distant star (nicknamed Earendel) at the "comoving distance" of 28 billion lightyears from Earth. Whatever that even means, since the star was formed only 900 million years after the Big Bang (when the universe was much smaller than today) and ceased to exist after only a few million years. The star literally doesn´t exist anymore, yet its previous position is *now* 28 billion lightyears away from us (at least at the previously mentioned "comoving distance"). 

Or something.

Still, it *is* fascinating...
