Question: what would the edge of the universe look like

There’s two ways of looking at this. You have the “observable” universe, and you have the universe itself. Light is super fast (300000000 metres per second!) but it still has to travel. And because our universe is only so old (on the scale of 1,000,000,000,00 seconds old) we can only “see” so many metres across.

Now, your observable universe is unique to you – imagine a big ball around yourself – nobody else can be in the centre of your ball, because that’s you! Now pretend that the ball isn’t a physical object – other people can walk in and out of your ball. If you stand just far enough from somebody else so the edge of your balls are just touching, you’ll see that the edge of those balls (or the observable universe) is just more space. So at the boundary of the observable and non observable universe, there’s no difference! Space just continues on.

But at the edge of the universe universe?T echnically, “nothingness,” but who’s to say what “nothingness” is! I don’t have a clue!
