Yeah, if you mean it that way then the conjectured phenomenon providing the fuzzing seems to be basically at-or-around Plank-scale stuff which arises from havin

Yeah, if you mean it that way then the conjectured phenomenon providing the fuzzing seems to be basically at-or-around Plank-scale stuff which arises from having the Heisenberg uncertainty principle around (because there's a hard boundary on the precision with which a process could demonstrate that space is empty, so in practice, it's not strictly empty, just a close approximation that's can have quantum fluctuations).
