Back to the quantum world, the reason that "quantum entanglement" may violate relativity is that if the information transfer is faster then the speed to light then that is a violation. According to relativity nothing in the universe can faster then the speed of light. Brian Greene, a theoretical physicist explained why this way; "the whole universe is moving at the speed of light, but objects that we percieve as moving slower then the speed of light the reason is that the energy is being converted into time which results in a slower velocity for that given object."

It maybe that "quantum entanglement" uses a mechanism that we can not detect, or do not understand. When it comes to the "quantum world" things are not as they seem.
