The ionization increases, the astronomers
say, near
black holes that are swallowing up matter at a higher rate relative to their
mass, which creates more radiation capable of stripping away electrons.
It comes from the spinning space - time around the
black hole and in fact it is not very well known, but that energy is there for the taking — up to 29 percent of the so - called rest
mass energy of a spinning
black hole is extractable — an d original conjecture, which is not, as I
say [
said], yet established fact, but certainly taken much more seriously than it was at that time — 10 or 15 percent of the rest
mass energy of the
black hole, about half of the spin energy, is in practice according to our conjecture, is in fact, the power source for these relativistically moving jets.

black holes — which result from the collapse of massive stars at the end of their lives — will be about the same
