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.

I couldn’t have designed it better.

Delta Force game programmers: Ghm, that was a trivial solution to the problem.

So... is Rick the top God or are there infinite simulations?

And that is scary. If the is one takeaway from observing the universe it's that there are always bigger and stranger things out there somewhere.

A bit off-topic but the voids in the universe (such as Bootes void) are scary af.

You could never get to the void because space-time has already accelerated the edge of all matter away from you faster than the speed of light.

Or the quantum foam, or both, it'd be wild to be able to stare out into that sorta of black, in a metal way.

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?

It does sort of feel like we're in the butthole of universes, doesn't it?
