The gravitational pull from black holes is so strong that nothing can escape its grasp. So could we ever harness the gargantuan power of black holes as a source of energy?
In a new study, scientists propose two ways to use black holes as energy sources someday. They predicted processes for extracting energy from black holes by using their rotational and gravitational properties.
"We know that we can extract energies from black holes, and we also know that we can inject energy into them, which almost sounds like a battery," lead author Zhan Feng Mai, a postdoctoral researcher at the Kavli Institute for Astronomy and Astrophysics at Peking University, told Live Science.
