Is time travel possible through cosmic strings?
Are there any other ways to achieve time travel?
There are a lot of different theories about time travel, but the most promising concept, at the moment, is called the "Alcubierre warp drive." This theory involves compressing space in front of a spacecraft and expanding it behind the spacecraft, creating a kind of "warp bubble" that allows the spacecraft to travel faster than the speed of light. This could conceivably allow for time travel, although it's still very much in the realm of theoretical physics.
