The way we can detect black holes is because when atoms get crushed the electrons are converted to x-rays. So by using a telescope that detects x-rays we can see where lots of x-rays are coming from and we can assume that this is a black hole.

∙ 8y agoWe have found powerful sources of X-rays that can be best explained by matter heating up just before falling into a black hole. We have also found cases of stars orbiting unseen objects that have a very high mass but are unseen and seem quite small. By our current understanding only a black hole could be that small with that large of a mass.

How did Karl schwarzschild discover cosmic black holes?
He did not discover them. He did some calculations that predicted the possibility of the existence of black holes.
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 have black holes got to do with the beginning of the universe?
The density of matter just after the big bang is calculated to be sufficient to have spontaneously created black holes; such are called primordial black holes, and searches for their existence are ongoing.
Are black holes in space?
Yes, that's where they are. A black hole on Earth would utterly destroy the Earth, in a very short time.The existence of black holes is now generally accepted, by the way.
How do astronomers search for black holes and what are the challenges of learning about them?
There are two ways of finding black holes. They can look for the effects that their gravity has on nearby objects and they can look for X-rays emitted by matter about to fall into them. A major challenge is that black holes themselves do not emit any light, making them impossible to detect directly.

Do black holes orbit the universe?
Most likely not. The best evidence of the existence of black holes has been found deep within galaxies.

What forces black holes?
The existence of black holes is an outgrowth or prediction of General Relativity, which was Einstein's theory of gravitation. The dominant force forming black holes is the force of gravity, a universal attraction between mass.
Is the black hole a wormhole?
Probably not. The existence of black holes can be considered to be confirmed; the existence of wormholes is highly speculative, that is, they probably don't exist at all. According to String Theory, worm hole does exist. However black holes are not warm holes. Even if you did found a wormhole, it probably going to be only about 1 atom small.

Which of these is one likely to encounter in deep space black truffle black algae black hole black coffee?
The effect of the existence of black holes is supported by observational evidence. There have as yet been no observations that would support the existence of the other items on this list.
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.
What physical theory first predicted the existence of black holes?
The general theory of relativity, proposed by Einstein in 1916, embodied the notion of gravitation, a phenomenon derived from a local curvature of spacetime. One profound implication, an outgrowth of the field equations of the theory, was the existence of black holes.
Did black holes exist in 1999?
Black holes did exist in 1999, and long before that. While black holes cannot be observed directly, they have been hinted at having existed by Einstein. The first real recording of the side effects of a Black hole was in 1971.
What did Stephen hawking say about black holes?
His major contribution to the theory of black holes is that they will gradually evaporate, due to certain quantum effects close to the event horizon.
