There is no physical “edge” where you can’t go past, but I think there is an “edge” where, past that, nothing has yet occupied.



But see you’re still under the impression that there is the Universe, and there is some ‘other’ thing in which the universe is expanding into, and that’s not the case. And whether there is a finite or infinite universe, there is nothing that it’s expanding into.

To say there is something “outside” the universe means that outside the universe needs to somehow exist. But we say that all that there is of space and time, “everything that is everything” is inside of our universe (that’s what “universe” means). So therefore if you go outside of the universe there ceases to be dimensions, there ceases to be any time, and that nothingness can’t be labeled as something. You can’t really even say there is “nothing”,because that implies there are spatial and time dimensions where there is no mass/energy. You reach this point where philosophy breaks down.

People have notion that if it’s finite the universe has to be expanding into something, some X-dimension. However that goes against what we talked about above. Instead it’s better to think of it like this: consider it as everything that’s everything is expanding.

And of course my sphere analogy is just that…an analogy. To ask what is inside the sphere is nonsensical, like asking what’s south of the south pole. There is no additional dimension you could jump off into. The universe has no boundary.
