Black holes, whatare they? Is it a big hole in outer space or a big ball of gas? Albert Einsteinquoted that ” Black holes are where God divided by zero.” In 1961 physicist Karl Schwarzschildsuggested that black holes were real.
Ten years later in 1971 astronomer named John Wheeler saw a black hole forthe first time. Astronomers have discovered that there arethree parts to black holes. The first part is the outer event horizon, which isthe border of the black hole and eats up light. The next is the inner eventhorizon, which is stronger. The third and final is called the singularity whichis the center and strongest part of a black hole.
Like things in life, there are manyvarieties. Black holes have three: stellar, intermediate and the supermassive.The stellar black hole is form when a single star explodes and continues tocompress. Intermediate black hole is formed when multiple stars collide in achain reaction of a explosion. Finally is the supermassive black hole which is werehundreds or thousands of stars collide. Black holes are unique because they work bysucking in everything and anything, while gaining mass until Hawking radiationeventually destroys them. Hawking radiation, named after StephanHawking in 1974.
It’s invisible particle pairs constantly be formed around theouter event horizon. Normally, a particle, antiparticle pair form and theyquickly annihilate one another slowly decreasing the black hole in size. The purposeof Hawking radiation is to keep black holes in check There are many mysterious facts stillremaining black holes. For the facts I have shared with you today are only thetip of the iceberg.
No need to worry the closest black hole is only 27,000 light years away. As SubrahmanyanChandrasekhar quoted “The black holes of nature are the most perfectobjects there are in the universe; the only elements in their constructions areour concepts of space and time”.
