Summary
[edit]DescriptionCausality and Superluminal information flow.svg |
English: At time, t=0, Alice will send Bob a message he will receive before she sends it. The train is equipped with a hypothetical instantaneous signal delivery device. Two photons at the center C are sent to the front F and rear R to verify that the message is received the instant it is sent. Alice waits till the front reaches her to send the message that Bob had received a short while ago when the rear of the train passed him. The consequences of a prompt reply (from Bob to Alice) using a similar device is sufficient to convince most that superluminal communication is impossible. The small arrow in Alice's timeline marks the arrival time of this reply. See also File:Causality_and_Superluminal_information_flow1.svg |
