Quantum Theory on Alternate Realities

[boy genius]

could someone give me some information on the quantum theory on ulternate realitys

Ya mean, Moltiple Wurld interpretations ?

cheers,

no not really i mean that
say if you said yes to a question in one realty in another you would say no and in another you would have never been asked the question at all.

That is the multiple world interpretation (MWI) of quantum mechanics that Patrick mentioned. Instead of branching every time there's a yes-no alternative, as in many science fiction parallel world stories, MWI branches every time there's a "reduction of the wave function" to more than one eigenvalue. It amounts to the same thing; there are worlds where everything that didn't happen here happened.

You can try reading this paper, its real fun.

You wouldn't happen to know Abia Ubong, would you?
