Quantum physicists have long known that after two particles — photons, for example — interact, they sometimes become "entangled." This kind of experiment has been repeated many times, and involves taking two entangled photons and sending them to different places. Perhaps photon A goes to Los Angeles and photon B goes to Boston.

When photon A is observed, it has a certain polarization, perhaps "up." The other photon in Boston is always in the opposite polarization, "down." No matter what measurement is made of photon A, photon B will always be opposite. It is impossible to tell what the polarization will be before you measure it, but the entangled photons always seem to "know" the right state to be in, instantaneously.



I would love to know this answer. I got a theory but it's to crazy to state here....But i would l Love to here from GLP..
