NASA publishes the discovery of a galaxy cluster at 12.6 billion light
years:
http://www.jpl.nasa.gov/news/news.cf...y&auid=7616512
It has a central black hole of approx 30 million suns. Our own
galaxy has a central BH with only 2.6 million sun masses.
(from
http://www.eso.org/public/news/eso0226/)
Now, 1.1 billion years is a VERY short time for a cluster.
Our own galaxy does 4 revolutions in that time only, imagine
building a CLUSTER of galaxies in that time.
Bsides, supposing that the black hole started growing immediately
after the big bang, it should have been eating 0.2727 sun masses a
year to achieve that mass... without interruption.
I remember when people told everyone that no cluster of galaxies
would be discovered beyond 7 billion years. Then it was 9, later
was 10.
Now we are at 12.6.
