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!
Oh please, as if Fox News could produce that much energy, then they'd be useful for something.
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.
You forgot the Bennett whatever-his-last-name-is dump.

I'd hate to be at just a mere 2.6 lightyears distance from an event that caused two volumes both 600000 lightyears across to be filled with hot, X-ray emitting gas.
Therefore, by the (faulty) logic you're using, you're just a cow with a keyboard - osu-neko (2604)
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
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.

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.
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.
