The infinity documentary was “A Trip To Infinity” on Netflix, and the simulation theory one is available on YouTube at https://youtu.be/pznWo8f020I

But there is a finite amount of smallness before things get to be as small as it is possible to be. I watched a documentary on infinity and it did I’m whether infinity is large or small, but I also watched a documentary on the theory that we are all just existing inside a simulation and that claimed that we have discovered the finite amount of smallness that makes up everything, essentially our “pixels” and that it just simply doesn’t get any smaller then that. So the conclusion I have drawn is that things get much infinitely bigger than they can get finitely smaller.
