'Monster' Black Holes Activate When Galaxies Collide
Yahoo News ^ | 6/22/2010 | Space .com

Posted on 06/21/2010 1:37:59 PM PDT by Dallas59



Enormous black holes, some of the most powerful sources of radiation in the universe, apparently switch on after galaxies collide, researchers have found.

The centers of as many as a tenth of all galaxies generate more energy than can be explained by stars, with some of these "active galactic nuclei" releasing more radiation than the entire Milky Way galaxy combined, but from a space no larger than our solar system. Astronomers suspect this energy is released when matter falls into giant, supermassive black holes that are up to billions of times the mass of our sun at these galaxies' cores.

"These monster black holes evolve in a way that is strongly related to the amount of dark matter that surrounds them and that is intimately related to the probability of galaxies to merge," said study lead author Nico Cappelluti, an astrophysicist at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany.

Help, I’ve fallen and I can’t reach my event horizon.

They only SWITCH on, in the same sense that tornadoes switch on as the result of a collision between two weather fronts.

“These monster black holes evolve in a way that is strongly related to the amount of dark matter that surrounds them and that is intimately related to the probability of galaxies to merge,”

Or, in layman’s terms, collision results are unpredictable, but pretty!

Do black holes ever get full?

Since the Milky Way is reputed to have a black hole at it’s center, just which galaxy did it collide with, and when?

Depends. Does 'stuff' just go 'in'? Or does it go 'through'?

Do black holes have a preference for dark matter?

Don’t know but Stephen Hawking claims they do put out visible light known as Hawking Radiation.

Watching a Discovery show the other night I learned that science cannot correlate the amount of mass in the universe with the amount of gravity so they invented "Dark Matter and are now searching for it.

Can't account for missing energy in their calculations so someone invented "Dark Energy" and are now looking for that.

One fellow noticed some unusual movement of stars in his studies and has coined the term "Dark Flow".

Makes one wonder what dimension these fella's belong to.

More pseudo science making up explanations for things they have no concept of.

If dark matter falls into a black hole does it heat up and radiate?

But we must keep guessing and proving our guesses so we can prove there is no creator. When we finally prove a lucky guess, we again will learn how abysmally ignorant we really are.

Isn’t the term black hole racist? /s That’s what the NAACP said. They thought it was code for “black whore”....lol

NAACP does not speak English.....or understand science....and apparently is against education.

I think that was discovered in the future:

I think it’s primarily scientific shorthand. Something doesn’t fit, manufacture a hypothesis - given the constraints of physics - test it against what’s better understood. Peer review in physics, chemistry, geology, etc, is still pretty hard to buck. It’s the political “scientists” one needs be on the lookout for.
