The Halo Drive

Video Description

How could we one day travel between the stars with real physics? Perhaps the greatest challenge to interstellar flight is energetics - it takes vast amounts of energy to accelerate even small ships to 20% the speed of light. But what if we could steal that energy from where? Perhaps even a black hole. Enter the "halo drive", a video by Prof David Kipping based on his new peer-reviewed research paper on the subject. This video is based on research conducted at the Cool Worlds Lab at Columbia University, New York.
