	I have to side with Darren on this. Your assertion that the electron is 
passing through two slits at the same time is merely your imposing a 
certain belief onto the system. Yet, any attempt to *directly* verify 
your theory will fail.

	When I learned quantum mechanics, the professors (and probably the 
books) tended to be careful not to make statements like these. The 
emphasis is always, "I don't really know what's going on, and so we're 
not going to waste time pondering over it. We have this abstract 
quantity known as the wavefunction, and a formalism about it that 
actually does work statistically, and we'll focus on that."

	The wavefunction of a particle is nonzero in a whole region - perhaps 
in two disconnected regions. They'll all say that. But the (serious) 
books don't go from that to saying, "The particle is in two places at once."
