What is the effect of differing frames of references between entangled particles? For example, let's look at the below scenario: Photons are entangled in Alice's frame of reference on say earth. Photon B is put on Bob's spaceship that travels at say 95% the speed of light. The other photon A stays with Alice on earth in a frame of reference moving at zero velocity. At 10 am Alice measures her photon and finds it to be spin UP. Now in Bob's space-ship (at 10 am, per the Alice's frame of reference) what would Bob find? Since photons move at speed of light are the even effected by differing frames of references? So instead let's say we take something slower than photons and entangle them and give to Bob and Alice. Please make/state the additional assumption/scenarios, if any, that need to be made, before such a question can be answered.
