But thanks to new research, there might be a highly efficient way to harness the highly energetic particles emanating from black holes to help human colonists keep the lights on.by researchers from Columbia University and Universidad Adolfo Ibanez in Chile, we could theoretically extract energy from black holes by harvesting charged plasma particles escaping from the event horizon, the boundary beyond which no light can escape.
In an off-Earth civilization in the distant future, this could serve as an invaluable source of energy when setting up an off-Earth civilization, according to to Comisso.published in June in the journal, charging it with negative energy. By cutting it loose, we could harvest the resulting energy in the form of recoil.
Black holes lose energy by accreting negatively charged particles. In other words, "it is like a person could lose weight by eating candy with negative calories," Comisso said. "This might sound weird, but it can happen in a region called the ergosphere, where the spacetime continuum rotates so fast that every object spins in the same direction as the black hole."
