Indeed, but the way the math for expansion works is that there is something called a Hubble horizon and that makes it impossible to ever reach the edge, since it is moving away from us faster than light. (The limit doesn’t apply to the expansion of space-time).
Quite a nifty solution by the Supreme Programmer to avoid us hitting the limits of the simulation. I couldn’t have designed it better.
Well it was a more convincing solution than just having level crossing arms come down and an infinitely long train cross every time you get near the edge.
Something tells me this isn’t a bad thing. If there is an edge of the universe, it’s probably going to be a very strange place.

Good thing there isn’t one since we probably live in a donut.
I thought it was technically a three-dimensional donut shape progressing along a sort of 4D torus that we only exist on the “surface” of?
That’s a common misconception. We actually live on the surface of a 3D bear claw progressing along a 4D cruller.
