Where have black holes been found?
Scientists predict that there are over one million black holes in our galaxy
Ways you can detect black holes?
Since you can't see a black hole, scientists use a method called gravitational lensing to detect black holes. Since black holes warp space-time, the light that travels near a black hole is bent, like how a magnifying glass warps the object a little at the edges. Scientists look for unusual distortions of light caused by this effect to look for black holes.
How many black holes were in this galixy?
Black holes are a bit hard to detect, so I am pretty sure that not all black holes in this galaxy are known - and I suspect there is not even a decent estimate. But you can expect there to be several.
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.

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.
How can you use a spectrometer to detect black holes?
You can't use spectrometers to detect black holes. Telescopes are the only way to detect them.
How do people know that there was a blackhole if they don't see it?
Scientists can detect black holes by using x-rays and gamma rays. Black holes still can release matter, and black holes give off a lot off x and gamma rays.
How you detect black holes?
They are invisible.
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.

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
How many black holes happen?
It is not known how many black holes exist. One of the main reasons is that, if matter is not actually falling into the black hole, it is impossible to detect.
