mreddie1611 Posted February 6, 2011 Posted February 6, 2011 Would the exchange of information at a speed faster than c be equivalent to sending information into the past?
lemur Posted February 6, 2011 Posted February 6, 2011 It would be equivalent to sending information toward past information. Does information have its own present or does it always refer to some other moment in time that it re-presents?
Schrödinger's hat Posted March 1, 2011 Posted March 1, 2011 It would be equivalent to sending information toward past information. Does information have its own present or does it always refer to some other moment in time that it re-presents? Umm does not compute. At the risk of repeating what lemur said in case I don't get it. Information about future events could reach past events. That is effects could precede causes. I just realised this would do strange things to the laws of thermodynamics and OWWW MY BRAIN!
swansont Posted March 1, 2011 Posted March 1, 2011 You can easily construct scenarios where superluminal communication allows you to get a response to a signal before you send it. http://en.wikipedia.org/wiki/Minkowski_diagram#The_speed_of_light_as_a_limit
