My friend just gave me a good thought experiment involving quantum entanglement violating special relativity that I can't seem to refute.
There are two immortal people A and B. A and B synchronize their clocks far away from any gravitational influence (say spot Y). B departs for spot(at an infinitely slow speed...therefore they do not lose synchronization) X a 1000 light years away from the place they synchronized them. There is a pair of electrons quantum entangled at spot X and Y. Before leaving A told B to kill himself if the electron that he measured was spin down. After a certain pre-decided interval A and B both make the measurement. A measures that his electron is spin up. Therefore, B is dead. Does that violate special relativity?
