No one has ever seen a black hole; so how do we know of them? Well, scientist's measured to movements of planets and saw them all moving toward a force. Now, we believe that there is something in the center of the galaxy that is pulling planets and stars towards it. Scientist's measured that this force is strong enough to decease anything that comes in contact with it. We call this force a "Black Hole". Why is it called a BLACK hole? Well, it is so strong that not even light can escape it.
What else can I help you with?
Why are you safe from black holes?
Why am *I* safe from black holes? Because the nearest one from my planet is 1600 light years away. I don't know if that means YOU are safe from black holes -- I don't know the distance between your planet and the nearest black hole -- but I know my safety is assured.
What do scientists what to know more about in space?
Black holes
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.
Can you reach a black hole?
No, we don't know of any black holes close enough to get to.
What do you know about the black holes?
Quite a lot - I have been reading about them regularly.
What is a good title for a project on black holes?

How many black holes are in your galaxy?
No one will know for a long time. We know of some, but not all.
Was a planet or anything else sucked into a black hole?
We have seem evidence of objects falling into black holes, but most of what we have seen is probably gas. We do not know of any planets that have falledn into black holes.
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.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Are black holes dangerous to people?
Black holes could be dangerous to people if people were close to a black hole, but there are no black holes near the planet Earth (as far as we know) and the closest one is probably in the center of the Milky Way galaxy, which is about 80,000 light years from Earth, which is a safe distance.
How do tides affect black holes?
Given that tides are caused by gravity, and that black holes are a major SOURCE of gravity, it isn't clear that black holes would be affected at all by other gravitational sources. Of course, we can know nothing at all about whatever is inside the event horizon of a black hole.
