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.”
In 1961 physicist Karl Schwarzschild
suggested that black holes were real.
Ten years later in 1971 astronomer named John Wheeler saw one for the
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. Next is the inner event horizon, which is
stronger. The third 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 form when a single star explodes and continues to
compress. Next is intermediate black hole is when multiple stars collide in a
chain reaction of explosion. Finally, is the supermassive black which is forms 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 being created around the outer
event horizon. Normally, a particle, antiparticle pair form and they quickly annihilate
each other, slowly decreasing the black hole in mass. The purpose of Hawking
radiation is to keep black holes in check.
There are more mysterious about black
holes. For the facts I have shared with you today are only the tip of the
iceberg. 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”.
