Warp Drive

Warp drive (or Alcubierre Drive) is an alternative interstellar propulsion mode to the Jump Drive that may be used for the universe setting.

Quoted from Wikipedia :

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. Thus, the Alcubierre drive does not contradict the
conventional claim that relativity forbids a slower-than-light object
to accelerate to faster-than-light speeds.
