How To Build A Black Hole Laser
You can amplify light by bouncing it between the horizons of a black hole and a white hole. Now physicists have worked out how to build such a device in the lab
In short, the “black hole laser” can be replicated by making a waveguide out of diamond and letting a pulse of light bounce back and forth… duplicating the effects of bouncing back and forth between a black hole and a white hole event horizon, gathering steam on each bounce due to Hawking radiation.
Yeah, I don’t get it either.
