Fwd: big

'Researchers from Australia and China have turned up an unfeasibly large black hole that almost dates back to the beginning of time.

At 12 billion times the Sun's mass, and in a quasar that was a million billion times as energetic as the Sun, it's not actually the largest black hole ever spotted. However, its redshift indicates that it's a black hole from very early in the universe.

That's the problematic part, according to Dr Fuyan Bian from the ANU's Research School of Astronomy and Astrophysics, who in a press release said: "Forming such a large black hole so quickly is hard to interpret with current theories".

At a redshift of greater than 6.30, the quasar, designated SDSSJ010013.021280225.8 (SDSS J0100+2802 in short) is one of only around 40 with that redshift, indicating that they formed in a much younger universe. This particular quasar formed when the universe was less than a billion years old, the researchers say.

Its huge size and age means it must have "gained enormous mass in a short period of time", Dr Bian said. However, as we currently understand black hole formation, this quasar shouldn't have had enough time to get so big.'
