Can somehow confirm that my understanding of the EPR Paradox is correct. Here goes...
Essentially you can entangle two photons, and send them in opposite directions. If we detect one of the photons, we can find out its properties, and since the properties of the two photons are linked, also that of the other photon.
Quantum mechanics says the photon we didn't measure does not even have a certain state, and so we shouldn't be able to tell anything about it. This would suggest quantum mechanics is wrong.
The argument from the quantum mechanics side is that measuring the first photon causes both photons to take a definite state. This requires information to be transferred from the first photon to the other photon. Now, since, the photons being light, are traveling in opposite directions at the speed of light, we'd need the information to travel faster than the speed of light. This would go against special relativity.
First of all, is the above correct?
Secondly how do we explain the last bit so that it agrees with relativity?
