I am not sure how he would ever be able to prove this.

Doesn’t sound like he can.

The electron might be here. It might be over there.

QM can’t tell us for sure.
Neither can his theory.

New Law of Physics Could Explain Quantum Mysteries

Or the new law is being invoked to explain away problems caused by defective older laws; that is, someone came up with an idea, loved the idea, tried to reconcile it with reality, came up short, and then claimed that there was something in reality that we had not yet seen to explain the discrepancy between their predictions and observations.

I am not sure how he would ever be able to prove this.

As I understand it (not really at all...), the proof lies in the mathematical consistency of the theory. Whether all the "known" stuff fits correctly within it without fudging any numbers.
