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 a black hole for
the first time.
Astronomers have discovered that there are
three parts to black holes. The first part is the outer event horizon, which is
the border of the black hole and eats up light. The next is the inner event
horizon, which is stronger. The third and final is called the singularity which
is the center and strongest part of a black hole.
Like 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. Intermediate black hole is formed when multiple stars collide in a
chain reaction of a explosion. Finally is the supermassive black hole which is were
hundreds or thousands of stars collide.
Black holes are unique because they work by
sucking in everything and anything, while gaining mass until Hawking radiation
eventually destroys them.
Hawking radiation, named after Stephan
Hawking in 1974. It’s invisible particle pairs constantly be formed around the
outer event horizon. Normally, a particle, antiparticle pair form and they
quickly annihilate one another slowly decreasing the black hole in size. The purpose
of Hawking radiation is to keep black holes in check
There are many mysterious facts still
remaining 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”.
