called kinetic energy, which depends on speed," Pinochet added. "So, a rotating black hole has rotational kinetic energy, and by pulling space along with it, it imparts its extraordinary ...

The energy that Penrose and now Pinochet suggest could theoretically be extracted from black holes is the kinetic energy that keeps them rotating. Obviously, black holes aren't the only cosmic ...

In a controversial experiment, a team of physicists investigated whether we could harness the Earth's rotational energy to generate electricity. It's a deceptively simple idea that researchers ...
