Hello, I am attempting to write a script (for fun) which outlines a realistic scenario in which humanity travels to the stars within, say, 30 years. Given the short time frame, i'm thinking about using various forms of FTL travel. By my definition, FTL includes any means of getting from A to B faster than c without stuffing the universe. While the special theory of relativity apparently does not rule out FTL, it does impose some interesting bounds that I would to see if there is a way out off. I have a good understanding of Newtonian physics, and a basic grasp on some of the concepts behind quantum mechanics and relativity. I hope this in the right area to ask. I have done some research on this topic, but the answers seem to be conflicting. Questions: 1) Is it true that any form of FTL creates time travel? 2) Some claim a single bi-directional wormhole does not allow time travel. Is this true? 3) Are there any theory's out there, currently, that actually sound possible? 1) Lastly, how would you go about achieving FTL within your lifetime?
