Tbh I just learned from a documentary that the Hubble Ultra Deep Field image contains about 10,000 galaxies in a patch of sky the size of a grain of sand held at arm's length, which is a wild thing to think about.
Honestly, I was just watching a space doc on my couch last night and that stat made me put my snack down and just stare at the screen for a minute.

Forget the grain of sand, that's the easy part. The hard part is really feeling that each of those smudges is a whole galaxy full of its own stars and worlds. It just makes the whole idea of scale feel totally broken, doesn't it?
