Black Holes


Every day we look out upon the night sky, wondering and dreaming of what
lies beyond our planet. The universe that we live in is so diverse and unique,
and it interests us to learn about all the variance that lies beyond our grasp.
Within this marvel of wonders, our universe holds a mystery that is very
difficult to understand because of the complications that arise when trying to
examine and explore the principles of space. That mystery happens to be that of
the ever elusive, black hole.

This essay will hopefully give you the knowledge and understanding of
the concepts, properties, and processes involved with the space phenomenon of
the black hole. It will describe how a black hole is ...

is known as the event horizon. Behind this
horizon, the inward pull of gravity is overwhelming and no information about the
black hole's interior can escape to the outer universe. Applying the Einstein
Field Equations to collapsing stars, Kurt Schwarzschild discovered the critical
radius for a given mass at which matter would collapse into an infinitely dense
state known as a singularity.

At the center of the black hole lies the singularity, where matter is
crushed to infinite density, the pull of gravity is infinitely strong, and
space-time has infinite curvature. Here it is no longer meaningful to speak of
space and time, much less space-time. Jumbled up at the singularity, space and
time as we know them cease to exist. At the singularity, the laws of physics
break down, including Einstein's Theory of General Relativity. This is known as
Quantum Gravity. In this realm, space and time are broken apart and cause and
effect cannot be unraveled. Even today, there is no ...

All black holes are formed
from the gravitational collapse of a star, usually having a great, massive, core.
A star is created when huge, gigantic, gas clouds bind together due to
attractive forces and form a hot core, combined from all the energy of the two
gas clouds. This energy produced is so great when it first collides, that a
nuclear reaction occurs and the gases within the star start to burn continuously.
The hydrogen gas is usually the first type of gas consumed in a star and then
other gas elements such as carbon, oxygen, and helium are consumed.

This chain reaction fuels the star for millions or billions of years
depending upon the amount of gases there are. The star manages ...
