>>17 Lol. Good analogy.

Yes, time travel is possible under Einsteinian physics. Unfortunately we have no clue how it works nor how to move backwards through time. Since to move backwards in time forces us to break the speed of light, which also under Einsteinian physics is impossible. Tests have shown however that time travel is possible. We have tested and measured small instances of slowing time, most notably through the use of atomic clocks placed in orbit.
