Largest Eruption In the Known Universe Is ~100 Times the Size of Milky Way
StartsWithABang writes: At the center of almost every galaxy is a supermassive black hole (SMBH); at the center of almost every cluster is a supermassive galaxy with some of the largest SMBHs in the Universe. And every once in a while, a galactocentric black hole will become active, emitting tremendous amounts of radiation out into the Universe as it devours matter. This radiation can cut across the spectrum, from the X-ray down to the radio. At the heart of MS 0735.6+7421, there's a >10^10 solar mass black hole that appears to have been active for hundreds of millions of years, something unheard of!
Still sucks less than your mum.
Oh please, as if Fox News could produce that much energy, then they'd be useful for something.
The article has 6 huge pictures without any caption explaining what we're looking at. That makes it closer to a desktop wallpaper collection than to an article.
So that's where all the anti-matter went.

I would argue with with duration and length of the ejected material that the galaxy BLOWS as much as Fox News
IANAP but I think it doesn't escape once in the black hole. However, on the way there, matter gets mangled and ripped apart which happens before it actually crosses the event horizon. This is where these emissions take place.

I never understood this. It is said that the black holes are black because not even light can escape them. And yet, they emit light? How does the light they emit escape?
No light escapes from the black hole. The radiation that we're detecting comes from matter in the accretion disk. A disk of gas and dust around the black hole way farther than the event horizon. This matter is heated and accelerated by the gravitational forces of the black hole. That's why they radiate. If this matter were inside the black hole's even horizon then yes we wouldn't be able to detect it cause once inside the event horizon there is no escape. It's all way down to the singularity with no hope of escaping.
I actually enjoy reading these well written pop science blogs, but seriously, does every single post have to be featured on Slashdot???
This isn't your personal blog outlet.
No more "Startswithabang" please, unless it's actually News!!
Yes, if the attraction of McDonald's was so great that it pulled people towards it at a speed greater than the speed limit.
You forgot the Bennett whatever-his-last-name-is dump.

Very simplistic analogy:
You rip a sheet of paper, it makes noise. Once you finished with it, no noise would ever come out of it, but someone in the distance hears it and says "the guy made some noise while tearing some paper".

Not at all, because that is not a special property of McDonalds. People get speeding tickets going anywhere and nowhere, McDonald's doesn't cause it.
We hope your rules and wisdom choke you / Now we are one in everlasting peace
now with extra wikipedia links to paper over the ugly spammishness a bit. yet no link in the summary to the "creatively interpreted" paper shamelessly ripped off for this bastard blog post.
The galaxy is about 2.6 light-years away. That's relatively close. That seems kind of a coincidental. A far away one would probably be detectable because it's so powerful.
Table-ized A.I.
Yes, they do cause it, because they cause a fucking great accretion disk to form around them, and they provide some fucking massive magnetic fields to help fuel the accretion disk too. What's so fucking hard to understand about this? Oh, yes, that's right - nothing. You're either a troll, a moron or, most likely, both.
Fuck you, and fuck this website.
Black holes have massive gravitational and magnetic fields which do some rather violent things to matter that is near, but not in, the black hole. So while some stuff falls in, other stuff gets heated hot enough to emit x-rays, and some particles get ejected at tremendous speeds.
Don't waste your vote! Vote for whoever you want, unless you live in a swing state it won't matter anyways
So it's a bit like saying "McDonald's causes speeding tickets" because some people got speeding tickets on the way there?
Given the mass of their clients it stands to reason that there would be a gravitational anomaly causing cars to speed up the closer they get.
IAAP, although not an expert in black holes.
Even though black holes have an event horizon through which nothing is supposed to escape, it has been predicted that black holes can emit Hawking radiation at their event horizons, due to quantum effects.
If it weren't for deadlines, nothing would be late.
it does seem to work like this, with bodies of larger mass being attracted to it with greater force!
My God can beat up your God. Just kidding...don't take offense. I know there's no God.
due to time dilation, wouldn't those hundreds of millions of years (from our frame of reference) quoted in the summary be a much much shorter time window of from the reference from of the matter circling the black hole and emitting radiation just beyond it's event horizon? So that its' not the length of time that is unexpected, in some real sense, but the degree of time dilation? For all we know, it could have been a few moments of activity from that perspective.

Somebody modded me down. Seriously? I'm just providing facts.
If it weren't for deadlines, nothing would be late.
Don't give them any ideas. It's been a good while since we got bennettrolled.
People get speeding tickets going [...] nowhere
How did you manage that one?
Never mind, dumb question. I got a ticket once for failing to use my turn signal--while going straight.

Jokes aside, you're perpetuating a false belief.
It should be well known by now that gravity does not accelerate heavier objects any faster than lighter objects. The mass of the bodies is irrelevant if non-zero.
Ref Gallileo's alleged demonstration at the tower of Pisa.
Dude, you're the worse kind of pedant, the kind who is wrong.
It is indeed greater force (F = G * m_1 * m_2 / r^2)
Same acceleration due to /gravity/, but that's not actually what schlachter said.
Pop Quiz time: If you drop a 1 gram marble and a 1 gram feather, which one hits the ground first?
Of course it's not you gibbering idiot...
The mass of the bodies is irrelevant if non-zero.
This isn't correct. Mass is relevant to acceleration by gravity, otherwise you'd fall at the same rate on the Moon as on Earth.
The marble. Unless you are in a vacuum.
I should have said that the mass of an attracted object is irrelevant if the attractor is stationary. Like, one presumes, said McD station was thought to be.
When the relative difference in mass between two objects go towards infinity, the amount of influence the mass of the lighter object has goes towards zero. The pull a car has on earth, an astronaut on the moon, or a star on a galactic center black hole is so small that for all purposes they can be disregarded, and the greater objects be considered stationary.
Interesting mechanism thought to limit the amount a black hole can be consumed. Current thinking is that a black hole consumes, giving off energy in the form of jets and we get a quasar. A black hole will consume, and consume and consume some more, but they eventually consume so much that the mass of the black hole and the mass of the matter they are consuming begins to force objects outside of it's pull away from it, think toilet flapper that stops water after a flush. The black hole continues to consume the matter trapped in it's gravity emitting the energy until it's consumed all of the material in it's grasp. It's then thought to go silent or inactive. It's still there waiting for material to fall into it and it'll begin feeding again. This seems plausible otherwise what would stop black holes from consuming everything?
This is the current thinking around black holes at this time.
I am Bennett Haselton! I am Bennett Haselton!
That possibly doesn't apply to black holes, as their mass is ever changing based on what they consume.
I am Bennett Haselton! I am Bennett Haselton!
If so, it took them a while. From wikipedia: Recent work done by Brian McNamara et al. (2008)....
Apparently this has been known since 2008. But remember, you read it first here on slashdot!

I suspect my local McDs is traveling at 80% the speed of light!!! So I have to drive even faster than that to get to it!!
I just haven't found the right frame of reference in which I can prove it.
My God can beat up your God. Just kidding...don't take offense. I know there's no God.
Actually, no. Those 'EXTRAS' fox news throws in are called lies. Other news outlets tend to add spin to capture audiences. For the full story, talk to people that are there, go there, or do some thorough research on the internet. Fox will never bring more truth to the situation.
