Video: Video: Shooting light at binary black holes to accelerate spaceships might be one of the only ways for heavy spaceships to travel through space at relativistic speeds. This guy wrote a paper on it and explains how it works.

In our last video, the halo drive was discussed covering the basic physics of how this new system could potentially enable interstellar flight. Here, we go much deeper on the halo drive concept, exploring the concept further, answering many of the questions which have been raised, and going further by considering the possibilities of a galactic wide network of such systems. Enjoy!
