"Any usable warp drive implies the ability for time travel. Insert time travel into the universe and all hell breaks loose, literally. Perhaps among the infinite quantum multiverses we are one where neither warp drive nor time travel ever occurs, or both are impossible."

"If time travel into the past were possible we would be over-run with tourists from the future." I think Hawking said it, or possibly someone earlier.

Time travel into the future is manifestly possible; we are all doing it at a rate of one second per second. Seems dubious that the rate can be accelerated.

Time travel into the future is manifestly possible; we are all doing it at a rate of one second per second. Seems dubious that the rate can be accelerated.

Any round trip taken at speeds close to the speed of light will accelerate your travel into the future, without violating any known physical laws, and without requiring infinite energy.
