Black holes are found everywhere in the universe. There is a super-massive black hole at the center of our galaxy. It is strange. Our central black hole is (only) 26,000 light years away and about 4 million times the mass of our sun and yet we cannot see it directly. There are an enormous number of stars (and other black holes) orbiting our central black hole. The star clusters around our super-massive black hole are so dense, we cannot resolve the stars individually with our current technology.
There is another practical reason why we cannot see black holes directly. Nothing, not even light, can escape the gravitational pull of a black hole once a particle crosses the point of no return known as the event horizon. For this reason, we cannot directly ‘see’ a black hole. Like (other) dark matter, we can only know that a black hole is present from the behavior of the objects around it.
“At the center of every academic department, there is a black hole. Once a person has completed the involuntary trajectory into the organization’s black hole, the process of destruction has begun.”
