You can't see a black hole.
You can't see a black hole.
Black holes emit so very little radiation they are hard to see. Many black holes lie at the center of galaxies and there they are hidden by stars and dust.
Due to light being unable to escape the black hole, we cann't see it! It's like trying to see in a dark room with a flashlight, that has dead batteries. You cann't see the light because their is none to reflect.
Black holes does emit radiation, but they cannot be detected from earth. We use gravitational lensing to "see" the black holes.
Black holes are blavk because their gracity is so strong that light cannot escape for us to see.

There is enough evidence for black holes - I don't see any problem there.
The assumptions are not quite correct.Scientists CAN see black holes. In fact, black holes are among the brightest objects in the Universe. Of course, light can't escape from WITHIN the black hole; rather, what we see is the accretion disk. Also, scientists are PRETTY SURE that black holes are real. As to why it is important: Black holes are fascinating objects by themselves. They also seem to play an important role in galaxy formation.
None. Black holes are completely black, making them invisible, so it would be pointless to put something you can't see in a constellation.
You cannot see our sun.
black holes The black hole we see is the Event Horizon. Its realy not a hole. Just a spherical region in space where matter ceases to exist.
Black holes are invisible because they do not emit any light. Light cannot escape from a black hole due to its strong gravitational pull, making it impossible for us to see them directly.
