A5 3 Theoretical Feasibility of a BH-Powered Starship

Abstract

This paper investigates a theoretical propulsion concept in which the energy source is present in
space: a miniature black hole. The spacecraft would harness Hawking radiation emitted by the
BH and redirect it opposite to the desired direction of motion, producing thrust without relying
on stored fuel. The underlying physics, potential efficiencies, and key engineering challenges of
such a “BH starship” are explored.
