Traveling forward would be theoretically correct but that's all theorizing according to Einstein when you start to reach the speed of light. Your gravity will become immense in fact so much there might never be able to create any thing that would hold up. Another theory is that immense mass and gravity could preserve some one. Supposed a person where to go into a black hole (if the supposed hawking radiation doesn't kill you first) for five years they came back to earth everyone else would have aged four times faster 20 years older.
