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.
specifically, "astronomers" that study black holes are called cosmologists.
Yes, black holes are known and regarded by many scientists, astronomers, and physicists.
Black Holes
Astronomers
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.
Black holes do not emit light, so we cannot observe them directly
Astronomers say that there are several, possibly many, black holes, all a long way from Earth.
Astronomers believe that there are black holes, but I will add that they have only been observed indirectly at great distances, so it may be that the interpretation of our observations will change in the future.
no dude, the evidences of the existence of black holes is now widely accepted and i believe that black holes rules our universe but it is difficult to find them because black holes are nearly the perfectly black bodies
Although the disciplines may overlap with others, it's safe to say that generally astronomers, physicists and astrophysicists study black holes; particle physicists study particles.
Yes. In fact, it looks as if all, or most, larger galaxies have huge ("supermassive") black holes in their center. The largest black holes found so far have an estimated 20 billion solar masses.
Because the astronomers can detect that a star is being whirled around in space, or space is being distorted.
