Warp drives are staples of science fiction, and in principle could propel spaceships faster than the speed of light. However, there are many problems with constructing them in practice, such as the requirement for an exotic type of matter with negative energy. Nevertheless, physicists have been exploring the theoretical possibility of warp drives for decades, and a new study published in the Open Journal of Astrophysics takes things a step further – simulating the gravitational waves such a drive might emit if it broke down.
