What are black holes made of?
There have been hundreds of threads, including a very recent one, on exactly that topic. I suggest a forum search (always a good idea for fundamental questions like this). A good place to start is the threads linked at the bottom of this page.Will K said:What are black holes made of?
A black hole is a region of space where the gravitational pull is so strong that nothing, including light, can escape from it. This is due to the extreme curvature of space-time caused by a massive object.
Black holes are formed when a massive star dies and its core collapses in on itself. The intense gravitational force causes the star to shrink and its density to increase, eventually becoming a black hole.
There are three main types of black holes: stellar black holes, intermediate black holes, and supermassive black holes. Stellar black holes are formed from the collapse of a single massive star, intermediate black holes are larger than stellar black holes but smaller than supermassive black holes, and supermassive black holes are found at the center of galaxies and can be billions of times the mass of our sun.
Black holes are made of a singularity, which is an infinitely small and dense point at the center, surrounded by an event horizon, which is the point of no return where the escape velocity is greater than the speed of light. They also have an accretion disk, which is a swirling disk of matter that is being pulled into the black hole.
Black holes themselves cannot be seen, as they do not emit light. However, we can observe the effects of black holes on their surroundings, such as the distortion of light and the gravitational pull on nearby objects. Scientists use various telescopes and instruments to study these effects and gather information about black holes.
