Yep. Existential uncertainty is a bitch, especially when combined with underlying issues.

Unfortunately, while we can be pretty sure we're not in "the matrix," there really isn't any compelling evidence to conclusively disprove the universe being a sufficiently advanced particle simulation.

There's a fastest speed, a highest energy level, smallest distance, shortest amount of time, etc. Universal expansion even puts a hard limit on how much of the universe we can ever explore, making everything beyond that effectively a skybox.

There's a smallest distance and time period? I don't remember hearing we'd discovered proof that spacetime was quantized.

They're technically the smallest "meaningful" units of distance and time but, for the purpose of finding something that would actively disprove a simulation hypothesis, there's no significant difference since they're still be on a fine enough scale to function as the simulation's "voxel grid" and "ticks" with no observable difference to pure analog.

I'm referring, if you hadn't already guessed, to the Planck Units for volume and time.

EDIT: Spelling fix
