There are two ways of finding black holes. They can look for the effects that their gravity has on nearby objects and they can look for X-rays emitted by matter about to fall into them. A major challenge is that black holes themselves do not emit any light, making them impossible to detect directly.
Astronomers think that the areas around black holes suck everything in like when a tub drains. But black holes are large amounts of matter that is packed into a small area.
That's because they actually observed it.
An astronomer is a scientist who studies celestial bodies (planets, stars, black holes, moons, nebulae, galaxies).
His health problems.
As a matter of fact there is only one problem. We can't find out what goes on in a black hole because humans don't have a rocket, suit, or a camera that will not be destroyed when it's just getting a few miles close to it.
specifically, "astronomers" that study black holes are called cosmologists.
Astronomers are constantly investigating and collecting information on any objects in space that have not yet been cataloged. In the course of doing this, they find and identify galaxies, nebulae, novas and, of course, black holes. They just "turn up" frequently as part of the never-ending search of the universe and the objects in it.
Astronomers know because they have studied star patterns and placements and know when there has been a change between where there is a black hole and where there isn't one.
Black Holes
Yes, black holes are known and regarded by many scientists, astronomers, and physicists.
Black holes do not emit light, so we cannot observe them directly
By observing the movement of nearby objects.
blah blah black sheep

Astronomers say that there are several, possibly many, black holes, all a long way from Earth.
