Reply To: Retrocausality is intrinsic to quantum mechanics

Daniel Rohrlich

Dear Travis, you have misunderstood. What I meant by “exceeding the speed of light” was superluminal signaling, exactly in the sense of Aurelien’s comment, to which I responded: “Clearly, you cant use this scheme to transmit faster than light signal which could then be equivalent to backward causation and convince me.” I do not rule out faster-than-light causation that is nonsignaling.

Best, Daniel
