Does FTL transmission of information (via 1 entanglement or 2 any means) violate causality? FTL = faster than light 1. I argue that FTL (of information) does NOT violate causality or relativity. 2. Also FTL (of massless information) is possible via quantum entanglement. All you need is a DCQE setup (without EM radiation) or any apparatus that can exploit entanglement for information transfer purposes. For 1 above: relativity says mass (rest mass) cannot travel FTL, however in information transfer via quantum entanglement no mass is being transferred only information is. quantum entanglement provides a way to transmit information without mass (having to carry it) also, according to my hypothesis, quantum entanglement happens in channel/dimension other than space-time or is not effected by space time. There is NO mass involved, so no problems with relativity. Nor with causality. The future is not/cannot effecting the past. For 2 above: All you need is a DCQE setup (without "noise" EM radiation) or any apparatus that can exploit entanglement for information transfer purposes (in which "noise" EM radiation is kept close to zero).
