Mostly by theory and computer simulation. All observations are necessarily indirect.

How many people know about Black Holes?
As many people that looked up this question :)
If nobody has ever seen a black hole how do you know what they do?
People know what black holes can do because of the aftermath. Stars and planets have been completely destroyed.
Did scientist send unmanned spaceships into a black hole to gather information?
No. The nearest known black holes are many light-years away. Everything we know - everything we THINK we know - about black holes is theoretical. Guesswork.
What effect did black hole's give us on society?
Black holes will help us know more about how things grow, live and die. Rod's answer ; Black holes help us to know that if we don't ask Jesus into our hearts before we die, we will be in one forever. Just finishing my book showing the similarities between black holes and Hell and the Lake of Fire. No joke. God's out there for real!
Do black holes have any connection to Greek or Roman mythology?
No, black holes are a matter of science and it is very unlikely that the ancient Greeks or Romans observed the anomaly or studied it to later tell in myths we know.

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.
If nobody has ever seen a black hole how do you know what they do?
People know what black holes can do because of the aftermath. Stars and planets have been completely destroyed.
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.
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.
Why should someone know about black holes?
The question isn't why learn about black holes but why. The thing is it's just fascinating to learn about them. I mean it can rip anything apart even basic atoms. Now that's a powerful force. I mean some people always wondered what happened to stars. It just so happens that if their big enough they will actually implode then explode in some of the greatest explosions in the universe. Now do you under stand why people like them so much?
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.
