Black Holes Grow By Eating Quantum Foam

An anonymous reader writes "The discovery that even the most distant galaxies have supermassive black holes at their cores is a puzzle for astrophysicists. These objects must have formed relatively soon after the Big Bang. But if a galaxy is only a billion years old and contains a black hole that is a billion times more massive than the Sun, how did it get so big, so quickly? Now one cosmologist says he has the answer: black holes feed off the quantum foam that makes up the fabric of spacetime. This foam is 'nourishing' because it contains quantum black holes that can contribute to the black hole's growth. This idea leads to a prediction: that the supermassive black hole at the center of the Milky Way must also be growing in this way and at a rate that we should be able to measure. Just watch out for the burps."

There was some concern of the hypothetical danger creation of such black holes might pose.

More concerning to me was the uninformed speculation that lead to those concerns. As one physicist quipped here on Slashdot at the time, "You misunderstand what motivates physicists. If the LHC did get sucked up by a mini black hole we would not run from the building in fear, we would run towards it with notebooks at hand".
