by the x-rays they give out and the elliptical path of the stars circling around pure darkness.
There are a few ways. Since stars are so far, you can't observe the black hole directly, but you can observe the effects that the intense gravity from the black hole creates. For instance, a star with a black hole as its twin will behave as a star in a binary system, but you can't see the twin. So, you can assume that there is an invisible object nearby influencing the orbit of the twin.
Other ways are observing in different wavelengths - radio, infrared, ultraviolet and X-rays. If a black hole is consuming matter, it will often be active in these other wavelengths.
As black holes consume matter, they often throw out jets of highly accelerated matter and energy. These jets can be observed.
Thus, by combining the methods above (and others), you can determine where a black hole is.

∙ 12y agoIf black holes DID exist, we would see three things occuring near them:
1) large amounts of matter being sucked into a central core, emitting large amounts of radiation, including x-rays, as it does so.
2) stars would be in orbit around this core, with orbits that can only be explained by a large amount of mass in a very small volume.
3) light from behind a black hole would be bent to the extent that objects behind it would appear to be in a gravitational lens.
Astronomers see exactly those events in several spots in our galaxy, and the only reasonable explanation is a black hole.

∙ 12y agoIt's by inference.
1) the math says that black holes should exist.
2) nobody has figured out what else could make stars follow the orbits that they take near the center of the galaxy -except- for a black hole.

Where have black holes been found?
Scientists predict that there are over one million black holes in our galaxy
Do white holes suck up objects like black holes do?
no. white holes are actually an object predicted by scientists to exist on the other side of a black hole. it is predicted to spit out objects that entered a black hole.
Why is the lack of direct evidence on black holes a problem for scientists?
I am not sure it is a problem. The evidence for black holes is quite strong.I am not sure it is a problem. The evidence for black holes is quite strong.I am not sure it is a problem.

How do scientists detect black holes?
They use X-Rays from the stars being sucked into them.
Why was it so hard to prove that black holes exist?
no dude, the evidences of the existence of black holes is now widely accepted and i believe that black holes rules our universe but it is difficult to find them because black holes are nearly the perfectly black bodies
What scientists have their name to researching of black holes?
Steven Hawking is researching black holes right now.
Are black holes known?
Yes, black holes are known and regarded by many scientists, astronomers, and physicists.

What do scientists what to know more about in space?
Black holes
Why is the lack of direct evidence for black holes a problem for scientists?
There is enough evidence for black holes - I don't see any problem there.
How does a black holes acquire greatest mass?
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
Do scientists have x-ray evidence that black holes exist?
Yes.
Where did a black hole come from?
Most black holes form when massive stars exhaust their fuel and their cores collapse. There are also supermassive black holes at the centers of most galaxies. Scientists are not sure how supermassive black holes form.
Do white holes suck up objects like black holes do?
no. white holes are actually an object predicted by scientists to exist on the other side of a black hole. it is predicted to spit out objects that entered a black hole.

Is their black holes?
Yes, there is such thing as a black hole, they are very mysterious and very, very, very hard to see. But, scientists don't try to "look" for black holes, they detect them with radars that search for vibrations in space. Scientists look for these vibrations because the black holes give off this energy with gigantic force that pulls you into the center. It has so much energy and force that it vibrates. So, yes there are such things as black holes.
If scientists cannot see black holes and do not know for certain that they exist why might studying them be important?
The assumptions are not quite correct.Scientists CAN see black holes. In fact, black holes are among the brightest objects in the Universe. Of course, light can't escape from WITHIN the black hole; rather, what we see is the accretion disk. Also, scientists are PRETTY SURE that black holes are real. As to why it is important: Black holes are fascinating objects by themselves. They also seem to play an important role in galaxy formation.
