| Feb 18, 2023 at 6:38 | comment | added | Peter - Reinstate Monica | I think the premise is wrong. Isn't there a non-zero probability to find any particle anywhere? It's just that the probability drops very quickly with the distance from the classic solution. But at sufficient resolution, the universe simply is "fuzzy". | |

| Feb 16, 2023 at 21:00 | comment | added | Kevin Kostlan | Diffraction is the uncertainty principle for light. Passing through a smaller pinhole (tighter position) will cause more diffraction (looser momentum). The classical wave equation as well as Maxwells equations also have this property, so "uncertainty principle" is related to waves in general and isn't irrelevant for non-quantum systems. | |

| Feb 16, 2023 at 17:00 | comment | added | Sarah Messer | Why doesn't light have a trajectory? A reference would be useful for context. "Trajectory" is a particle-dynamics concept, but is only vaguely mapped to wave dynamics. "Light" could mean either a particle or a wave. Heisenberg Uncertainty Principle is focused on particle approximations. Astronomy is typically in the "ray optics" subdomain of wave dynamics. | |
