If theories of their existence are true,
black holes are the most powerful force in the
known physical universe. Many people are familiar
with the term black hole, but few people actually
know anything about them. A black hole forms as
a result of a massive star running out of fuel to
burn (Chaisson, 193). Once the star is no longer
exerting outward force by burning off gases, it
begins to collapse under it's own intense, inward
gravity (Chaisson, 193). It is like slowly letting the
air out of a balloon. Once the star is compacted to
a certain size, while it's mass, or weight, remains
the same, it's gravity becomes so powerful that
nothing can escape it (Hawking, 87). This critical
size to weight ratio is known as the Schwarzchild
Radius (Hawking, 87). Once a black hole is
created in this way, an invisible area, or line
around it exists. If any object crosses this line, it
can no longer escape the gravitational force of the
black hole (Hawking, 87). This line is......
