eli5 How do we know we’re not just wrong when we say there’s uncertainty in particle physics

244 views

So given how for example we can’t know an electron’s position and velocity at the same time and other small scale observations and measurements involve uncertainty and randomness. Is there any solid proof that we’re not just wrong? I know all science is inherently possibly wrong and is a model of best fit but this part of science in particular seems so arbitrary to actually be a good model.

Generally we consider that it’s not that we “don’t know” a particle’s position and velocity to perfect precision at the same time, so much as that the question doesn’t make sense. The concepts of “position” and “velocity” as we understand them for large classical objects, like rocks, just don’t work the same way at a quantum level. Asking for the “position” or “velocity” of an electron, especially under complicated circumstances like the two-slit experiment, is simply asking the wrong question. It’s like an alien reading about countries, and then asking what the “population” or “governmental structure” of a single person is.
