Black holes, what are they? Is it a large hole in outer space or a large ball of gas? Albert Einstein quoted that ” Black holes are where God divided by zero.” In 1961 Karl Schwarzschild, a physicist suggested that black holes are real. Ten years later astronomer John Wheeler saw one. Black holes as we know so far have only three parts. The outer event horizon is the first which is the border of the black hole and able to eat light. The next one is the inner event horizon, which is stronger. The thrid and final is the singularity which is the strongest and is also the center of the black hole. Like many things in life, there are many types. Black holes have three, stellar, intermediate and supermassive. Stellar black holes is when a single star explodes and continues to compress. The intermediate black hole is formed when lots of stars collide in a chain reaction that create an explostion. Finally, supermassive black holes is hundreds or thousands of stars collide. Black holes are really something else because they work by sucking in everything and anything, getting bigger and bigger until Hawking radiation eventually wipes them out. Hawking radiation, named after Stephan Hawking in 1974 is invisible particle pairs constantly being created around the outer event horizon. A particle, antiparticle pair form and quickly annihilate each other, slowly making the mass of the black hole smaller. 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”.
