I understand the objections like causality and things like The Grandfather Paradox but I know there are theoretical pysicists that have circumvented these prohibitions to time travel. Putting them aside for a moment, explain what I have asked: the mechanics of just getting there.
I am writing a novel about time travel and don't quite understand the theoretical science behind it.
If I understand correctly, Einstein's General Relativity theory opened up the door for the possibility of time travel even though he dismissed the idea as impractical. Einstein proved...
Thank you bcrowell,
I am still a bit confused. I understand the general concept but would you elaborate on the specifics of(theoretical) time travel: for instance, say I want to travel into my past, just how would this be accomplished- I understand this is all in theory. Would I myself have to...
Would someone explain to me in lay men's terms exactly what a CTC is. I understand that it is a closed timeline curve and that it allows( in theory) time travel to one's past. My question is how does one get into a CTC: Do you have to be traveling in space and at a certain speed? Does one...
In theory, is time travel to the past possible by traveling completely around the loop of the CTC (where it would seem future links with its own past) or is a wormhole the only way to time travel by way of short cutting the CTC.
