So far as we can tell, the probabilities given by quantum mechanics are 
as much information as exists - the universe itself doesn't know where 
the electron will be detected before it happens.

OK, so you'd prefer to be able to predict exactly where the electron 
will land, but that's a philosophical point of view that the universe is 
not obliged to subscribe to.

In the EPR thought experiment, Einstein et. al. sought to show that 
quantum mechanics was incomplete - that there were properties that 
existed in the world that quantum mechanics left out. It turned out, 
after a considerable time, that their argument was flawed, as Bell 
demonstrated.

Until you can show that there really are omitted properties, such as the 
eventual position of an electron, it's just speculation.

Sylvia.
