Black Hole in Search of a Home
jose parinas writes "Interesting news from the ESO observatory on Paranal about black holes that travel. From the article: 'For 19 of [the low redshift quasars], they found, as expected, that these super massive black holes are surrounded by a host galaxy. But when they studied the bright quasar HE0450-2958, located some 5 billion light-years away, they couldn't find evidence for an encircling galaxy. This, the astronomers suggest, may indicate a rare case of collision between a seemingly normal spiral galaxy and a much more exotic object harbouring a very massive black hole.'" More from the article: "Has the host galaxy been completely disrupted as a result of the collision? It is hard to imagine how that could happen. Has an isolated black hole captured gas while crossing the disc of a spiral galaxy? This would require very special conditions and would probably not have caused such a tremendous perturbation as is observed in the neighbouring galaxy. Another intriguing hypothesis is that the galaxy harbouring the black hole was almost exclusively made of dark matter." Update: 09/17 00:15 GMT by Z : Edited for clarity.
Hope that doesn't happen to the milky way.
is that the explaination for everything these days? "hmmm that can't be right... lets blame it on Dark Matter!"
Could the moderators check the grammar before submitting?
20 20 sounds like the results of an eyesight test, and ' found that for 19 of them, they found,' - what?

I volunteer to adopt it, I think it would make a great companion plus the added perk of being an infinite power source.
*rolls up newspaper* but if it starts behaving badly, we're gonna have a problem.
This sig contains repetition and redundancy.
I would be interested in how this data applies to the Stephen Hawkings theory of radiation expelled at the end of a Black hole - his come-back theory that everyone is still waiting to hear about. Dark Matter though compelling leaves us with more questions than answers.

"...a much more exotic object harbouring a very massive black hole."
This brings Uhura's "exotic" dance in Star Trek V to mind.
Mr. T pitied this fool on 27 July 1992.
You let one in and there goes the whole neighborhood!
Well, it's nice to see Slashdot editors actually implementing one of the community's ideas. Some suggested that submitting test phrases to /. would be the way to get started; it's only been two days, and already the software seems to be going into production. Of course, it'll be awhile before the program gets out of beta, but still, kudos to the /. editors for acting so quickly.
sig not ready: (A)bort, (R)etry, (F)ail.
Definitely a case of grammatical structure in search of a home!

welcome our black hole throwing overloads...
its all fun and games untill someones galaxy gets hit with a black hole...
Has an isolated black hole captured gas while crossing the disc of a spiral galaxy?
If it's anything like my uncle, it doesn't capture gas, it releases it... in large quantities...
Not gonna lie, this kind of stuff kind of scares me. Colliding black holes, black matter, etc. No sir, I don't like it.
And not in my backyard.
Sounds like lots of uhm, we don't really know, but we can guess, and it's like uhm, scientific and stuff since we like, got our PhD's, and we have expensive toys and stuff. Oh the grand religious order of science. Tell me what does God have to say about this? Oh depense to me my reality from the high academic papal order. Ah we are in Virgo. What does that say about wandering black holes and quasars?
just 'consumed' the galaxy it started with? sure it would take a long time, but it's probably been there a long time.

...honey, I shrunk my galaxy
I read
Scientists are baffled as to how the different handed socks ended up in completely separate galaxies. However, some have stated that the apparent long-range transport phenomenon does provide hints for the mechanisms behind unexplained sock behaviors in this part of the universe.
A reasonable person might well consider an explanation that included the natural evolution of advanced technological civilizations before they resorted to the invention of new particles and laws of physics (as is typically a requirement as soon as you mention 'dark matter').
It is useful to keep in mind that several papers by Charley Lineweaver's group document that ~70% of the "Earth's" in our galaxy are significantly older than ours (perhaps billions of years older). It would not be that unexpected that from time to time we might encounter a galaxy where advanced civilizations had placed *all* of the reasonably available matter and energy "under management". (For the purposes of discussion we will assume that black holes do not constitute a "reasonably available" useful resource despite proposals from time to time that require rather creative physics to make them "useful".)
Trust me when I say that there are far more areas of science that are scarier. Quantom mechanics states that there are either multiple copies of us in dimensions or that we can live in a quasi state inbetween life and death. Humans creating black holes providing proof of multiple dimensions. Little teeny tiny particles streaming through your body as you are reading this.
This is indeed a dark matter...
If the Big-Bang was discovered to be just a stage in the Steady State Theory?

This black hole will bite the hand that feeds it.You are 0wn3d say big black letters for infinite amount of time. Can you imagine what will happen if such a rogue elephant comes wandering in our backyard? We will have much bigger problems to worry about.

He may be an asshole, but I agree. Microsoft is pretty good these days.
Holy Fscking Shirt! This has got to be a first! A Slashbot actually edited content!
G f'n D - Hell finally froze over!
You got that right, Bill!
Is this a science story or another report from the flooded slums of New Orleans?
*_rimshot_*
What? Too soon? OK OK my wife says I'm going to hell but I think its funny.
I read that headline as: a black hole was discovered in someone's home. ...Noooooooo...being sucked in...force of gravity too powerful...aaaaaaahhhhh!!!
I can imagine the scenario:
Man: Don't go in there officer, trust me!
Officer: Are you trying to hide something boy?
Man: No, it's just that, umm...
Officer: Well we'll just see about what's behind this door, shall we?
...sucks news from /.
Love slashdot, but digg.com is going to suck this user base dry.
Not only is this and many other stories old news, you get too much Gay Nigers of America and First Post crap.
Mod me down, but we are getting to a point of critical mass here.
Hungry Hungry Hippos, and just ran out of stars.
Sorry about the writing. Robot fingers, you know? Cliff Steele in DOOM PATROL #23
Some used the stargate to move it
The host galaxy is *inside* the black hole. It got "eaten" completely. To me this sounds pretty realistic if it's a huge black hole...
Any sufficiently advanced intelligence is indistinguishable from stupidity.
What if the supermassive black hole was rotating such that it's poles were pointing into the disk of the parent galaxy?
The artilce mentions that there is eveidence that a companion galaxy has collided witht the quarsar withing the last 100 million years or so (relative to the observation).
If so, when the collision occured and provided material to feed the quasar, the polar jets would have plowed right into the parent galaxy, and perhaps blowing away the gas in the disk over that 100 million year period.
Any thoughts on this?

The sixth day God said: let the super-massive black hole swallow this entire galaxy, and he saw it was good.
Shouldn't we at least send one probe at each ends of the black hole and see what really going on. or Send a nuke and see which is stronger. lol
Hey, Slashdot has a tradition to uphold!
Or actually... A reputation to improve!

Is there a web based equivalent for google earth but in the other direction? Where you can zoom in on coordinates and see ever higher resolutions? If not, why the &#%$ not?
It hurts my head to even think about that.If you could stop movement beyond singularities ,the universe would have to be attracted to it,an increased mass would be observed.This is my abstract view of a blackhole.That would only be true if the universe had no voids, and if it had a minumum speed limit .I have no other way of putting it,sorry.
