The joker:
Don't forget as well the small issue of time, there simply isn't enough time in the universe to get to the speed of light (with the time dilation that occurs), the heat death of the universe would guarantee that there is no workable energy, so no more acceleration.

we imagined an engine or device that bends space in front of a spaceship in a certain way and space behind the spaceship in a certain way causing the ship to get carried along in the expansion and contraction of space. It's sort of like riding along with the waves.
Sounds like the Alcubierre drive:
quote:
In 1994, the Mexican physicist Miguel Alcubierre proposed a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship would ride this wave inside a region known as a warp bubble of flat space. Since the ship is not moving within this bubble, but carried along as the region itself moves, conventional relativistic effects such as time dilation do not apply in the way they would in the case of a ship moving at high velocity through flat spacetime. Also, this method of travel does not actually involve moving faster than light in a local sense, since a light beam within the bubble would still always move faster than the ship; it is only "faster than light" in the sense that, thanks to the contraction of the space in front of it, the ship could reach its destination faster than a light beam restricted to travelling outside the warp bubble.
