Black holes and their host galaxies, growing old together

Yes. The late physicist Stephen Hawking proposed that while black holes get bigger by eating material, they also slowly shrink because they are losing tiny amounts of energy called "Hawking radiation." Hawking radiation occurs because empty space, or the vacuum, is not really empty. It is actually a sea of particles … See more A stellar-mass black hole, with a mass of tens of times the mass of the Sun, can likely form in seconds, after the collapse of a massive star. … See more The research involves looking at the motions of stars in the centers of galaxies. These motions imply a dark, massive body whose mass can be computed from the speeds of the stars. … See more It certainly wouldn't be good!
