I read somthing about quantum mechanics. It was talking about an atom or somthing anyway... it said that what they were trying to messaure was somthign about spin up and spin down between two particles that had intereacted and that if particle A had down spin particle B had up spin but untill you measure it they both have both types of spin. does this mean that if a person doesnt see somthing it doesnt exist or isnt real or somthing?
