Black hole starship

A black hole starship enables interstellar travel by propelling a starship by using a black hole or kugelblitz as the energy source.

A black hole starship offers some advantages compared to other possible methods. For example, in nuclear fusion or nuclear fission, only a small proportion of the mass is converted into energy, so enormous quantities of material would be needed. One possibility is antimatter, but the manufacturing of antimatter is hugely energy-inefficient, and antimatter is difficult to contain.
