17 billion suns?

Quote:
Astronomers have uncovered a near-record-breaking supermassive black hole, weighing 17 billion suns, in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe. The observations, made by NASA's Hubble Space Telescope and the Gemini telescope in Hawaii, could indicate that these monster objects may be more common than once thought.

Until now, the biggest supermassive black holes - those roughly 10 billion times the mass of our sun - have been found at the cores of very large galaxies in regions of the universe packed with other large galaxies. In fact, the current record holder tips the scale at 21 billion suns and resides in the crowded Coma galaxy cluster, which consists of over 1,000 galaxies..

Is it sparse because it's eaten everything there was and we can't actually see that far to confirm exactly how "sparse" it is..

Where do things that fall into these black holes go ?

Nothing falls in there, slowly the matter is pulled apart and on the other side it powers all the worlds unicorns .. which if any of this made sense, would mean that the "other side" is "this side" umm.

Its a good question. When they talk about the "mass" of a black hole that means nothing about it's size. Black holes technically don't have a "size" as you or I would understand it on an xyz graph in 3 dimensional space. This is part of the problem einstein had with them.

See general relativity, E=mc2 actually predicted the existence of Black Holes. Einstein wasn't responsible for that prediction, it was another scientist, Karl Schwarzschild, who used E=mc2 and predicted this weird event that could be mathematically proven to be possible. He didn't coin the phrase black hole, but the math certainly predicted them. He published his work and Einstein spent years trying to figure out a way to disprove it, only to come to the conclusion that these gravitational singularities were "impossible" objects which meant that his theory of general relativity was fundamentally flawed. He would for the rest of his life return to this question and try to figure out how his theory of relitivity was flawed, only to come away stumped every time. He would not live long enough to learn that actual proof of blackholes would be found and measured, and ultimately General Relativity wasn't flawed.

A Black Hole is basically the result of dividing by 0; or an object with zero VOLUME (3 dimensional measurements) and immense mass, in other words a "singularity" (gravity is a function of mass and volume, the smaller the volume and more mas an object has, the larger it's gravitational effect). In essence the black hole is so massive and the gravitational forces so infinitely powerful, that anything that falls into them, once crossing the event horizon simply stops existing in a state that could be described in normal physics, these items will be crushed down to "nothing" leaving only the concept of their mass behind, and adding to the mass of the black hole without actually leaving behind anything else.

A black hole is literally the death of everything, space, energy AND time. It wouldn't be a stretch to describe them as a rip in the very fabric of the 4 dimensional universe we observe today. When people talk about the size of a black hole what they're really talking about is the MASS, and occasionally if they're talking about it's physical size what they're talking about is the size of the event horizon. As the event horizon is an area of space with measurable boundaries, a boundary where the laws of the universe breakdown and not even light can escape from a black hole any longer; inside the event horizon matter and energy break down as they're drawn into the singularity and simply cease to exist.

FunFact: if our sun were to collapse and form a blackhole (not really possible, it's not big enough to cause that effect); it's event horizon would be only 6km across. If the earth were to collapse and form a black hole, the event horizon would be about the size of a marble.

this is what we ASSUME. we at this point know nothing that contradicts it in practice...

however in theory, Einstein-Rosen bridge and White holes (theoretical potential other side of a black hole) are still possible as we have not gotten to the point in advancement where it can be proven correct or incorrect.

Weird that something that goes in ceases to exist as anything within our surrounding does not exhibit this behavior either living or non living.

I wouldn't say that it no longer exists.

It would be more along the lines of the energy produce by said matter isn't strong enough to overcome the overwhelming gravitational force, this includes strangely enough light.

we don't know what happened to the light beyond it simply not reaching us. we don't know if there is another side or not, although it is safe i think to assume that we know we, as humans, cannot survive in that type of gravitational pressure to find out our self with current bleeding edge tech. (let alone get there TOO find out)

IIRC they are still trying to figure out gravity's effect on light and our understanding of it, and how it might change in the future based on these sort of findings.

Then why do black holes spew out gas?

Mass doesnt necessarily represent a component of conservation of energy does it?

Will the universe eventually be nothing but black holes that occassionally fuse together?

from what we can theorize, and this is coming from my layman understanding is that the jets that are emitted from the rotational axis of things like black holes are not actually coming from the black hole but from the matter forming the disk around the black hole.
basically i guess it is compressed so much in those two points before actually crossing the event horizon that it can escape at a speed relative to the speed it was being pulled into the black hole....basically the same thing as escape velocity.
so, the jets arent actually leaving the black hole as they never were part of it.

But if they are at escape velocity, should they be travelling at times more than speed of light since the black hole already exerts that much force to not let even light escape

i think they are still under the speed of light since they never actually crossed the event horizon, it may be at like 90% of the speed of light, but its still under.

Something similar to what spacecraft which perform gravity assists against giant planets ?

thats how i understand it, but i could be wrong.
