What is causing destructive interference in double slit experiment?

Click For Summary
SUMMARY

The discussion centers on the phenomenon of destructive interference observed in the double slit experiment involving electrons and photons. Participants clarify that the interference arises from the wave function of a single electron, which is described by the Schrödinger equation. The wave function represents a probability amplitude, and when the electron passes through the slits, it creates two potential paths that can interfere with each other, leading to observable patterns. The conversation emphasizes that quantum mechanics does not provide a classical explanation for these phenomena, but rather predicts probabilities based on the wave function.

Which brings me to ask: How could someone prove their theory true as to what is going on?
You don’t. Physics is an empirical science, and empirical sciences don’t prove that theories are true - it can’t be done. All that we can do is show that our theory is consistent with all experimental evidence so far, and it is helpful if our theory also makes predictions that are different from those of other proposed theories - then we can test the predictions to reject one or the other.

So any proposed theory of what is going in on (the technical term for such theories is, as @phyzguy says above, “hidden variable theories”) must be consistent with all available observational and experimental evidence so far. In particular, it must be consistent with the observed violations of Bell’s inequalities - and I strongly encourage you to read up on that, Googling for “Bell’s Theorem” would be a good start.
