The universe is estimated to contain around 10^22 to 10^24 black holes.
This description provides an overview of the estimated number of black holes in the universe. It is believed that the universe contains between 10^22 and 10^24 black holes, which is an incredibly large number. This number is so large that it is difficult to comprehend, but it is a testament
A black hole is an astronomical body so compact that its gravity prevents anything, including light, from escaping. Albert Einstein's theory of general relativity, which describes gravitation as the curvature of spacetime, predicts that any sufficiently compact mass will form a black hole. The boundary of no escape is called the event horizon. In general relativity, crossing a black hole's event horizon traps an object inside but produces no locally detectable change. General relativity also predicts that every black hole should have a central singularity, where the curvature of spacetime is infinite.
