Study indicates that energy can be extracted from black holes
A new study indicates that, someday, energy could be extracted from black holes.
A remarkable prediction of Einstein's theory of general relativity -- the theory that connects space, time, and gravity -- is that rotating black holes have enormous amounts of energy available to be tapped.
For the last 50 years, scientists have tried to come up with methods to unleash this power.
