How to Steal Energy from a Black Hole?

Steal Energy from Black hole

Novel simulations driven by analysts working at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley consolidate decades-old speculations to give new understanding about the driving instruments in the plasma streams that enable them to steal energy from black holes’ incredible gravitational fields and impel it a long way from their vast mouths.

This reenactment demonstrates a spinning black hole (bottom) and a collisionless plasma stream (top). The simulation demonstrates the densities of electrons and positrons, and magnetic field lines. The black hole’s “ergosurface,” within which all particles must turn indistinguishable way from the hole, is appeared green. (Credit: Kyle Parfrey et al./Berkeley Lab)
