Rigorous Science

Would the Hawking radiation from a small black hole make a feasible propulsion source?

+0
−0

I was wondering if a small black hole would make a feasible/possible propulsion source, and if so, how.

  • Pros
    • Black holes release Hawking radiation, would should be easy to direct in a certain direction.
    • Literally anything, from garbage to planets could be fed into the black hole.
    • It could provide artificial gravity
    • You can charge black holes, making it easier to contain.
  • Cons
    • The black hole could destroy the ship and everyone in it, and then it wouldn't being propelling anything

What size black hole would be possible, if any? At what rate should you feed it? How do you contain it safely?

We can assume basically any level of technological development that isn't magic (no gravity wizards). They also have near infinite amounts of energy.
