The Halo Drive
Astrophysicist David Kipping presents the halo drive, a proposed way to propel a starship to a good fraction of light speed by gaining energy from a black hole. The video is based on his peer-reviewed paper and explains why energy is the main obstacle to interstellar flight.

In The Halo Drive: Fuel-Free Relativistic Propulsion (2019)The halo drive concept is interesting. It uses a beam of light to extract gravity energy from a black hole and use to to maintain acceleration of your ship. Almost no fuel needed because its really just a kind of extreme gravity assist that we’ve …
