Also this;Of course the biggest problem with time travel is arriving at your destination. The assumption that time is a space curve and that we can cheat the curve of time by moving in a straightish line from the present to a point on the curve in the future.
If you could take off in a faster than the speed of light aircraft, you could head off for a year and come back to earth. However You would just have spent one year travelling very fast to arrive back at an Earth that had spent the same year travelling more slowly than you. Nothing would have changed, or would it.
The passage of time is less flexible than we think. While the speed of the earth rotating around the sun is the beginning point of our concept of time. In reality the Atomic Clocks should be the real reference points towards the passing of time.
Stick one Atomic Clock on your theoretical faster than light vehicle and after one year travelling at faster than the speed of light it will still read the same time as the Atomic clock back on Earth.
