| At the centre of most galaxies - including our own - there are super big black holes. Black holes can grow by absorbing surrounding mass, but once that is gone they normally do not find additional material to feed on. So how did the super big black holes form in the first place? There is a new possible answer which assumes that at the beginning of the universe fast gas streams were moving through the universe feeding these black holes. |
