bison Posted March 16, 2019 #1 Share Posted March 16, 2019 (edited) An astronomer has written a paper explaining how laser beams aimed at certain binary Black Holes could harvest energy from them. This would greatly increase the efficiency of laser propelled space vessels, also known as 'solar sails'. The laser beams would pass near the Black Holes and then outward again. In the process they would steal a bit of their kinetic energy, which could be transferred to the space ship. Near light speeds could be achieved at a relatively low energy cost. Further-- if this were a common practice, it might alter the orbits of the Black Holes over time, and in such a way that we could detect it. Please see the linked article below for further information. https://www.nbcnews.com/mach/science/astronomer-says-aliens-might-zap-black-holes-lasers-travel-galaxy-ncna983836 Edited March 16, 2019 by bison 1 1 Top Link to comment Share on other sites More sharing options...
