Black holes are hard to find as they are invisible.
This is because the escape velocity is faster than the speed of light. The escape velocity is the speed required to escape a black hole, if it is faster than light, the light can not escape therefore making them invisible.
Hope this helps....

∙ 10y agoA black hole emits no light, so it cannot be observed directly. It can be observed if matter falls into it - such matter will emit x-rays before passing the event horizon (the point of no return); its effects can also be seen by its gravitational attraction on other objects, such as nearby stars. But if there is no matter close to the black hole, there is basically nothing to be seen.

How do you locate a black hole?
Black holes emit Hawking Radiation, which is the only way of locating one from a great distance
Is it true that scientists believe that there is a black hole in space?
Black holes do exist - they are just VERY difficult to detect.
Is there ever going to be a blackhole near your solar system?
There may already be one. The nearest black hole known is a few thousand light years away, but it is easier to find black hole if they are part of a close binary system. A single star converting to a black hole, or a part of a binary system where the components are not very near, would be difficult to detect.There may already be one.

What is the present participle of the word locate?
The present participle of 'locate' is 'locating'.Example: "Locating missing children is especially difficult."
A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a black hole.
What is the closest black hole to Pluto?
It is actually difficult to determine the distance to black holes, but a nearby object believed to be a black hole from observations of strong X-ray emission is Cygnus X-1, located about 8000 light years away. Cyg X-1 is an ordinary star that is believed to be orbiting a black hole.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

Why would an isolated black hole in space be difficult to detect?
Exactly as its name suggests, black holes are black. You can not see them directly. If a black hole is isolated then there is no other large object in its near vicinity. We would be able to see the other large object and notice that it is wobbling instead of remaining perfectly still. This is an obvious indication that there is a dark object for the other large object to orbit around. The next step is to see if that dark object is a neutron star or a black hole. Another way to identify black holes is to check for high energy radiation. This is caused by particles on the horizon of a black hole that has reacted with other particles and released this energy. It is very difficult to find this sort of energy by scanning the sky with a telescope, but more importantly, if the black hole is isolated, then there is very little chance that there is enough particles on the horizon to react and release the high energy. Not only is it difficult to detect isolated black holes, but it is difficult to understand how they could be formed.
What does the black hole do to the star?
A black hole originated as a star, that is, the star converted to a black hole.
What does a black hole do with what it suck in?
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
Where will you go in a black hole it?
If you fall into a black hole, you'll go into the black hole and nowhere else.
Why do astronomers have a difficult time viewing black holes?
You cant see a black hole because the gravitational pull of it is so strong that not even light can escape from it. Astronomers find them through observing the space matter that they pull into them, not the hole itself.
