Black The first part is the outer event horizon,

Black holes, what are they? Is it a big hole in  space or a big ball of gas? Albert Einstein quoted that ” Black holes are where God divided by zero.”    In 1961 physicist Karl Schwarzschild suggested that black holes were real.  Ten years later in 1971 astronomer named John Wheeler saw one for the first time.    There are three parts of a black hole. The first part is the outer event horizon, which is the border of the black hole and still able to eat light. The second is the inner event horizon, which is stronger. The thrid and final is the singularity which is the strongest and center of the black hole.    Like many things in life, there are many varieties. Black holes have three: stellar, intermediate and the supermassive. The stellar black hole is  when a single star explodes and continues to compress. The intermediate black hole are formed when multiple stars collide in a chain reaction of an explostion.  Finally, the supermassive black hole is when hundreds or thousands of stars collide.    Black holes are unique because they work by sucking in everything and anything gaining mass until Hawking radiation eventually destroys them.     Hawking radiation, named after Stephan Hawking in 1974. It’s invisible particle pairs  constantly being created around the outer event horizon. Normally, a particle, antiparticle pair form and they quickly annihilate each other, slowly decreasing the mass of the black hole. The purpose of Hawking radiation is to keep black holes in check.    There are more mysterious facts about black holes. For the facts, I have shared with you today are only the tip of the iceberg.  But no need to worry,  the closest black hole is only  27,000 light years away. As Subrahmanyan Chandrasekhar quoted “The black holes of nature are the most perfect objects there are in the universe; the only elements in their constructions are our concepts of space and time”.
