Black holes are not detected, but rather their existence is inferred from observed phenomena which are attributed to the strong gravitational pull of a black hole. They remain a theoretical construct, however, as these phenomena can also be explained by taking account of forces other than just gravity, like electromagnetism, i.e. the forces that result from the separation of electric charge in plasma (see 2nd related link).
The black hole hypothesis has problems like the lack of any gravitational lensing of the stars that orbit the supposed black hole at the centre of our galaxy. Also, some scientists have come to the conclusion that it would be impossible for a black hole to ever form in the first place (see related link).
What else can I help you with?
How can you say there is a black hole?
You can't see the black hole but you can see its inflence on its environment. (You can see matter that is sucked into the black hole)
If nothing can escape a black hole in outer space how can you see photos of a black hole?
The answer is, you cannot see photos of a black hole. You are quite right; not even light can escape a black hole's incredible gravity, so all black holes are completely invisible. It is possible, however, to see long trails of matter that is being pulled into a black hole. The way we detect black holes from earth, however, is by picking up the gamma rays that they emit.
How can you see a black hole?
You cannot see a black hole directly. Which is probably just as well, since if you were close enough to see it, you would already be dead and fried by the radiation surrounding it. We can DETECT a black hole by that very radiation - the radiation generated as matter is accelerated to nearly the speed of light as it falls into the black hole. In fact, the first black hole ever identified, Cygus X-1, was detected by being a bright X-ray source with no visible star to account for it.
How do you pay for Annie anger management classes?
You give a lot of black men in the poo hole and you cant see them anymore
Is a black hole so bright that we cant see it?
Quite on the contrary - it's so dim that we can't see it: no light escapes from the hole. The only emission indicating presence of a black hole may come from accreting matter surrounding a hole. Although Hawking's radiation is associated with event horizon, it is undetectable at such distances.
Why cant you see blach holes?
The whole idea of black holes is that nothing, not even light, can escape from them. However, there are several indirect ways to detect them.
How can we see black holes?
You can't see a black hole.
Can we see black holes?
You can't see a black hole.
Can you see a black hole when you are on eath?
You cannot see a black hole when you are on Earth, unless a black hole were to absorb Earth, which even then, you would see it in a split-second before it would engulf you
Can you see a black hole with a telescope?
No, because nothing can escape the black hole, not even light. So without light, we can't see anything. but, we can see stars being stretched like spaghetti and then being sucked into the black hole.
What is black that you can't see in it?
A black hole
Can black holes be seen?
No. The gravity of a black hole is so extreme that nothing can escape, not even light. Since we humans see things based on the light that bounces off of them or radiates away from them, black holes are invisible. In fact, the only way we can detect a black hole at all is indirectly, based on its gravity.
