Quantum entanglement and Einstein's theory of relativity

  1. Nov 20, 2014 #1
    I have been thinking about this recently. Say two quantum particles, or two clusters of quantum particles, exist in the same universe. 1 is on, for lack of a better term, one side of the universe, one on the other. They are entangled. Because of the distance between them, one is in the future and one is in the past of the observer, who is in the middle, and can somehow see both of them. What would happen in one of the particles moved. because they are entangled they would be moving at the same time, but would the observer see them move at the same time, or would he see one move before the other?

    You cannot "see particles in the future".
    No. That is not how entanglement works.

    Quantum entanglement means the particles share a relationship not that they are connected or paired for equal motion.

    This should point you in the right direction:http://en.m.wikipedia.org/wiki/Quantum_entanglement

    As for the distance thing. Light is relatively constant for most objects in our universe. If the observer was in the middle then they would see objects move together. Now if the observer was next to one of the objects they would see the close object move then the far object. This is the basic understanding of Einstein's theory of relativity.
