Enormous black hole has outgrown its galaxy

Astronomers have discovered a supermassive black hole that appears to have grown to a ridiculous size.
Scientists had long believed that the growth of a supermassive black hole is closely linked to the growth of its parent galaxy meaning that one should generally remain proportional to the other.

This week however the discovery of a black hole containing ten percent of its host galaxy's entire mass has turned this idea upside-down and left scientists scratching their heads.

"This is really unexpected and was found in a really small survey, so it can't be that rare, unless we're just extraordinarily fortunate," said study co-author Professor Megan Urry.
"It's only one result and we shouldn't extrapolate, but if it were true then it would say that black holes grow substantially before the galaxies around them do."

The supermassive black hole in question, which measures a whopping 6.9 billion times the mass of the sun, is located in the distant galaxy CID-947 which formed two billion years after the Big Bang.

Most supermassive black holes are only 0.2 to 0.5 percent of the mass of their host galaxies.

I'm going to display my ignorance here, through my need of clarification. Are they saying they think galaxies are created from a giant black hole or that this is just an anomaly?

Is it possible that there was a colliding galaxy that could of boosted the size of the black hole momentarily as the new masses of sun's mixed into the galaxy and fed the black hole with extra matter

Black holes do not create galaxies at all... they eat them. One or more star's, planets, etc. at a time. Thus they "grow" This process occurs over a very long time-span, almost unimaginably long.

We need to immediately set out for this galaxy ASAP in a fleet of ships and rescue any intelligent beings there that are in danger from this monstrously malignant black hole. If we don't, then we are truly heartless cowards of the highest order. I hope the UN makes this its highest priority now. There's no time to waste. Hardly, decision will be vetoed most likely

It's actually a great question that hasn't been definitively answered yet. The relationship between a black hole and it's galaxy's creation is still somewhat of a chicken and egg issue. Pallidin's answer is 100% correct in how black holes behave, but there are still a few questions to be answered. Here's some light reading http://www.cosmotography.com/images/supermassive_blackholes_drive_galaxy_evolution_2.html http:/... [More]
