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?

Imagine you in a dark large room, your feet are glued to the floor, all you know about your universe is what you can touch. That is your observable universe. This only works if touch is your only sense btw.
Now imagine there are others in the room, each person has a different observable universe, some can touch others some can’t.
Each person knows nothing and can never know anything about what is beyond thier reach.
Now image there are no walls to the room, you’d never know you’re at the “edge” all you would know is you can feel something over here but can’t feel anything over there. For all we know the edge wraps right back around to the other side like a sphere or even like a video game you go to one edge and warp directly to the other edge.
