Are there any paradoxes involved in using worm holes for faster-than-light travel?
Is it possible to travel back in time and kill your parents before you were born? This ghastly possibility seems to lead to a contradiction, because if you are here, then your parents were alive, but if you killed them before you were born, you could not be alive now to kill them in the past. These kinds of paradoxes only occur if a space-time, or portions of it. Can have what are called closed timelike world lines. This would allow you to revisit some moment in your past and, presumably, allow you to wreak logical mayhem on your own future and existence. Curiously, general relativity allows such macabre opportunities to arise in certain exotic settings which preclude our universe existing in the first place. It is only when you bring the two ends of the worm hole back together that the possibility arises for a paradox to happen, because the local space-time gets so badly distorted that some world lines can be closed upon themselves. This is all just theoretical speculation, and I woul
