Re: Wormhole theory

I read in sci.electronics.design that ~~SciGirl~~ <palmtree117@xxxxxxxx> wrote (in <58Z2e.43$7b.7@trndny06>) about 'Wormhole theory', on Thu, 31 Mar 2005:

That doesn't make sense. Some go through one and others go through the other and some don't go through at all. How can ONE photon go through TWO slits at the same time? Pauli's exclusion principle says that no two can be in the same state, and one condition of state is position, at the same time.

Photons are bosons, but the Pauli principle applies only to fermions. Quote from:

http://www.ethbib.ethz.ch/exhibit/pauli/ausschliessung_e.html

"It turned out that the exclusion principle applies to particles with half-integral spin, e.g. electrons and protons. If these particles are described quantum statistically, then the so-called Fermi-Dirac statistics are employed. Such particles are known as fermions. On the other hand, particles with integral spin, e.g. photons, do not obey the exclusion principle and follow Bose-Einstein statistics. Such particles are known as bosons."

But this is not very relevant to the two-slit experiment.

So, ONE should not be able to have TWO positions at one time, either.

Or... let me guess, I'm mistaken again?

Yes. But don't be put off. It's one of the most initially astonishing demonstrations of quantum effects in action. Google gives a lot of hits, but this one seems to be pretty lucid:
