How much time is needed for the time travel?

    Of course, I know that time travel is still a science fiction, but I have heard that General Relativity allows this to happen.

    Where have you heard this? Provide a reference please. That you can construct space-times with closed time-like curves does not mean that it is actually implementable in our physical world.

    "I have heard" is not an acceptable reference.
