If you are a space travel fan:
WARP travel faster than the speed of light is possible. It would require a ‘machine’ that uses negative energy (black energy) to cause the surrounding universe to travel past the ‘machine’ like standing on a conveyor belt – the universe is expanding faster than the speed of light so relative to that WARP travel could equate to that. NASA hopes to have produced such a ‘machine’ by 2100.
REFERENCE: As dark energy causes the universe to expand ever-faster, it may spur some very distant galaxies to apparently move faster than the speed of light.
