> the real universe we live in bottoms out at 10^-35 meters or so We don't actually know this. It's a plausible speculation in quantum gravity, but we have no evidence either way. This length scale is about 18 orders of magnitude smaller than the smallest scale we can probe with experiments, so we're highly unlikely to get any evidence either way any time soon.
