Title:NASA Finds Black Hole Cluster
No matter how old you are, space never stops being cool. That applies doubly to black holes, which is why NASA's latest discovery should be considered totally awesome: using the Chandra X-ray observatory, the agency found an "unprecedented" cluster of black holes in the Andromeda galaxy.
How unprecedented? There could be 26 of them in this cluster alone. And these were just the ones that were immediately identifiable, as scientists say there are likely many more that are currently invisible. Said the lead author of the study, "We think it's just the tip of the iceberg." Cool.
They then realized they were looking the wrong way.
Instead of viewing deep space, they were staring at Washington DC.
They probably found it in their search for muslim outreach.
It may be cool in some way, but, I’m not feeling all warm and fuzzy about there being many invisible black holes.
And when enough of them get together there, and collide, do we get another Big Bang?
So this is kinda like the black caucus but useful?
They are not invisible...since they were detected and observed by Chandra....most likely through X-Ray imaging
can a black hole swallow a black hole?
and I mean that in a scientific-spacy way
NASA budget time ping!
Was it in the West Wing?
They looked at DC but all they saw was wreckem.
They found the Star Wars galaxies Great Maw..wonder if we can see Han Solo doing his Kessel run.
Absolutely. As long as one mass is sufficiently larger than the other black hole.
That is nothing. There is an entire family of black holes livin’ in the White Hut.
Yes, a black hole can swallow a black hole. It’s believed that the center of most galaxies, including our own, contain “super massive” black holes, which tend to be the culmination of many black holes collapsing in on themselves.
I don't think the relative size matters. If they are equal mass, they can merge. Probably not likely to have two objects of that sort of mass in close proximity, but if that does happen, there is nothing in any theory that I am aware of that precludes them from merging into a single object.
[as scientists say there are likely many more that are currently invisible.]
I thought they were all invisible.
Equal mass means equal gravitational pulls...so unless they collide they would just orbit each other. While no theory precludes it you have to figure that the chances of them colliding isn’t very likely at all.
Wow, a real-life cluster-dark.
How much did this cost us? We have an Unprecedented Cluster in the white house and that's cost us plenty already.
Orbiting isn't special when objects have equal mass. Objects of unequal mass orbit each other too, and just like objects of equal mass, "unless they collide they would just orbit each other." Or, be so remote from each other that "orbit" doesn't happen.
I do agree with your "probability" aspect of merging equal masses, just because of the diverse range of object masses.
At any rate, the initial question just had to do with merging black holes, which presupposes collision, and I wanted to clarify that given a collision between two black holes, the relative masses don't prevent merger. I think the logic is that once two event horizons meet, merging is inevitable. Neither object can escape the other.
Considering that each black hole is pulling in 'matter' as quick as it can, how likely is it that they have the 'same' mass ?
Going to the other end of the theoretical chalkboard, how can a HOLE have MASS ?
They would orbit until the event horizon of one
The question is can a stable orbit be maintained?
As the “hole” continues to pull in mass the EH would
continue to grow thus eventually degrading any orbit?
Does this mean at some point there will be only two
black objects in this universe? And what happens
when there is only one??? Critical mass?? and big bang?
Makes you wonder what kind of energy is released when
two reach that point??
Question for scientific minds.
If you and your flashlight had no mass and you turned
it on would you be moving at light speed?
Perhaps black holes are only elegant fiction.
Nothing like a black hole in space devoid of light and beauty to bolster the self-esteem of a muslim.
I’d like to toss this out here and see what comments it generates. Perhaps it will simply generate derogatory comments. If so, that’s okay.
I understand some aspects of what black holes are. The depictions I have seen sort of makes them look like a ring with blackness in the middle, some light escaping from the sides.
At times I have hard that we could be crushed by entering one. At other times I’ve read where that might not be the case.
If we enter a Black Hole, do we exit the other side?
Could Black Holes be worm holes? Could we enter one and wind up clear across the universe, or perhaps in another universe? Does anyone know?
Twenty-six black holes in a lose cluster..., kind of reminds me of a train station where you enter a certain tunnel depending on where you want to wind up.
They probably are, but when things move behind them, you can note the passage, and determine there is something there, especially if the light of the farthest object goes out during the passage.
The current administration is an Unprecedented Cluster.
That's not light. You might be thinking of escaping Gamma Rays.
Let me ask you this. Isn’t it possible for objects behind the Black Hole to show up as a ring around the hole do to the bending of their light as it passes the parimeter?
I suspect the pull of the Black Hole focuses at some aspect of the hole. This may prevent what I’m referencing. If the gravity has it’s most pull around the mouth, it might be possible.
At any rate, I’m probably referencing artistic license from depictions I’ve seen over the years. It would be hard for Hollywood to show a black hole on film if there wasn’t some light to differentiate the blackness from other blackness.

you sort of answered your own question. That's Hollywood!
Black holes are totally devoid of light. The only way I know they can be detected is by the erratic movement of mass around one, or once suspected a massive escape of Gamma Rays. I'm certainly not an expert but was always interested in cosmology.
I suspect that artists in both film and print used a lighter ring on the exterior to give us a reference point.
ive been poisoned i thought this said “NSA Finds....”
Clustered around the Zimmerman showtrial ?
Well, it doesn't suck as much.
“NASA Finds Black Hole Cluster”
Yeh, it’s obuma and his fascist administration.
Black holes are completely invisible themselves, as any light that passes the event horizon is completely consumed. That said, in reality, black holes are usually blazing with light, because as matter falls towards a black hole, it is accelerated and compressed by gravitic forces. As that matter heats up it begins to release light as energy, eventually running through the visible spectrum, and then on up into x-rays.
So the accretion disk around a black hole is ridiculously bright.
Now, if the black hole really was out in space with no matter falling in, it would still be really bright because of the material it ate before. Imagine a photon with just enough energy to stay above the event horizon. It slowly, slowly circles outward until it reaches a point where it can move away from the black hole, giving the hole a slow, rosy glow for millions of years after the last matter fell in.
Finally, if it ran out of that glow, it would still be visible by the massive distortions it causes in light, bending and lensing the light from behind it, and even the light coming from the viewer could be wrapped around the event horizon, coming back to create a sort of mirror image sphere shape, with distorted lens-like properties around it.
There’s a few pictures and more information here: http://www.universetoday.com/74462/what-does-a-black-hole-look-like/
Let me know when NASA finds and identifies the Great Attractor.
A black hole cluster would be Barry down low Soetero and Reggie Love doing the nasty.
We claim that our technology allows us to see to the center of a galaxy (we can’t even see ours), filled with billions of star and for now, at least, dozens of black holes, and there are trillions of objects between this one tiny spot and Earth including our asteroid belt and the fact that we are so close to the Sun that we are within the ‘flame’ area like the flame around a candle wick, and yet we can determine by insignificant ‘flickers’ in the light how many black holes there are, even though the amount of stars present is a WAG ?
God made Light good.
THIS IS YOUR BRAIN ON DRUGS. Andromeda Galaxy with lots of black holes.
Black holes are just the result of imploding stars of sufficient mass that end up so dense, that not even light can escape the gravity. Also, keep in mind that stars are just contained nuclear explosions, with sufficient enough gravity to keep said explosions contained. Once the fuel burns off (hydrogen turning into heavier elements that can no longer be used; mostly iron), the gravity exceeds the outward pressure of the nuclear furnace and the star collapses in on itself.
In some cases, the resulting implosion will end in a neutron star (pulsar, magnetar, etc.), but some will become black holes. Some of these will emit visible light and some won’t.
So, a black hole is basically not really a hole, as much as an exceedingly large mass that is crushed into an infinitely small space, which is supposed to tear a hole in space itself. In either event, black holes still emit “light”, but in the form of gamma radiation. We just perceive light in a very myopic spectrum...radio waves are light, X-Rays are light, etc..
Light that passes near a black hole will be diverted by the gravity, any rotation. Some light will be diverted all the way about. A rotating black hole can add energy to the diverted light and literally send it all the way around. But there will be a sort of ring effect visible from some distance even without rotation. This diversion caused by the gravitational effects and the deformation of the space time can result in all sorts of oddities, including the appearance of the universe "covering up" the black hole, strange changes in the apparent size, or even more bizarre things if the rotating object is distorted by it's rotation. There are models of the visual effects - sometimes reflected in the movies.
Of Course this is all theoretic. Getting close enough to see these effects is very dangerous. Rotating black holes can energize beams of particles and/or radiation that could vaporize the solar system at interstellar distances. Astronomers detect these things and we infer there are black holes at the roots. Astrophysics is not quite certain on the consequences of merging black holes, or the bizarre spacetime distortion caused by a cluster of the things. So I can imagine there's plenty happening that we can't even begin to imagine.
they’ve trained the telescope on the congressional black caucus?
>> so unless they collide they would just orbit each other.
That supposes blacks holes translate in space and would couple despite the momentum of one or both. Are the gravitational properties of two proximate black holes known or theorized?
