The observable universe. Does it mean the edge of space where nothing else is? Is it where the universe is currently at in its expansion after the big bang? Or is it just a barrier that our telescopes are yet to look beyond, and there are just more galaxies past it?

Alright, little buddy!
Imagine you’re inside a giant bubble. Everything you can see inside this bubble is the “observable universe.” It’s the part of space where light has had time to reach us, so we can see it. Outside the bubble, there’s probably more universe, but the light hasn’t reached us yet, so we can’t see it. As time goes on, our bubble gets bigger and we can see more! So, the “observable universe” is just everything we can currently see in space.
