My [lay] understanding is that a portion of spacetime has yet to be found that has 0 countable things. I also believe 'countable' gets tricky the more you zoom in, as it were.
I think that's the craziest thing, every time we get smaller, we find more stuff. "Atom" means "indivisible". It was supposed to be the smallest unit of matter.
Then we found things smaller. Sub-atomic particles. Literally makes no sense because it literally means smaller than the smallest thing.

The universe is apparently fractal af.
