Does that mean halfway across the known universe, or is it just a figure of speech for "a really long way away"? (Or is my assumption that the universe is infinite wrong?)
- junon 4y agoSince it's been located, it most likely refers to the "observable universe" - the sphere surrounding us (Earth) within which enough time has passed since the big bang that the EMR from the edge has reached Earth. Beyond that we have no idea what's there because that information hasn't travelled long and far enough to each us yet. It's kind of like a physics fog of war.
