Black Holes – Mark Cyr Black holes, what are they? Is it a big hole in outer space or a big ball of gas?Albert Einstein quoted that ” Black holes are where God divided by zero.” Physicist Karl Schwarzschild in 1961 suggested that black holes were real. To prove that black holes are real, in 1971 an astronomer named John Wheeler saw one for the first time. Astronomers have discovered that there are three parts of a black hole. The first part is the outer event horizon, which is the boundaries of the black hole and able to consume the light. The second is the inner event horizon, which is where the mass of the black hole is stronger and will not let anything it catches go. Singularity is the final part of the black hole as it is the strongest.There are three kinds of black holes, they are stellar, intermediate and supermassive. The stellar black hole is a large star that died and continues to compress, while the intermediate black hole is lots of stars smashing into each other in a chain reaction. The last kind of black hole is called supermassive. It is hundreds or could be thousands of stars that have fallen apart and squished together. The stellar and the supermassive black holes are the common ones. Black holes are unique because they work by sucking in everything and anything. The mass gets heavier and heavier until the Hawking radiation gets rid of it.You are probably thinking Hawking radiation is something to do with the bird but it is not. Hawking radiation, named after Stephan Hawking in 1974. It is invisible particle pairs constantly being created near thee black holes. Normally, a particle, antiparticle pair form and they quickly destroy one another and that makes the black hole slowly decrease in mass. The purpose of Hawking radiation is to stop black holes from becoming huge masses. There are still many unknown, facts about black holes to discover. The facts you have heard are only the tip of the iceberg, as the saying goes. Don’t worry, the closest black hole is 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”.
