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 called the
event horizon (Hawking, 87). If black holes are
proven to exist, beyond theoretical physics, then
they would probably be a very common anomaly
in this universe. In 1915, Albert Einstein put forth
the first real proposition of such an anomaly in his
“Theory of Relativity” (Bunn, Black Holes FAQ).
In the 1930s, three physicists, doctors Volkoff,
Snyder and Oppenheimer, were able to prove the
validity of black holes mathematically. Since then,
black holes have become a very important and
integral part of science and the over all
understanding of the universe. It has been proven,
mathematically, that black holes have infinite,
gravity based, escape velocities and an immense
effect on light, time and even the very fabric of
space. All bodies in space have gravity. According
to Einstein’s “Theory of Relativity”, this is because
bodies with a large mass, or weight, actually warp
space (Chaisson, 77). For example, if a two
dimensional sheet of cloth, stretched and
suspended at four corners, represents space, and
a bowling ball is placed in the center, the sheet will
warp downward. If a golf ball is then set at the
edge of the sheet and allowed to move freely it will
be attracted toward the bowling ball, unless the
golf ball is traveling at a speed great enough to not
be effected by the curve. This critical speed is
known as an escape velocity. This is the speed at
which an object must travel to e...

... the equations are
valid, wormholes most assuredly do not exist. If
they did it would probably send shivers up the
science fiction community’s spine. In the book,
Relatively Speaking, the Author, Eric Chaisson
says, “The world of science is littered with
mathematically elegant theories that apparently
have no basis in reality” (182). Although black
holes have not been conclusively proven to exist,
there is strong evidence, in the observable
universe, that they do. Black holes are very
important to the world of cosmology. They allow
for the study of common particles under very
uncommon environmental variables. Scientists
have vastly increased their knowledge of the
universe and the properties of matter through the
study of a black holes effects on light, time and the
fabric of the space. Works Cited Bunn, Ted

Physics of Black Holes Essay

- Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them....   [tags: physics space black holes]

Black Holes Essay

- Introduction Black holes are one of the more interesting topics in astrophysics. Even though they are commonly accepted as being real, their actual existence has yet to have been proven2. Black holes are objects that have such a concentration of mass that nothing can escape their gravitational pull once it crosses the black hole's event horizon or Schwarzschild radius. The Schwarzschild radius is the radius where, for anything inside, the escape velocity is greater than the speed of light....   [tags: space black hole]

Black Holes Essay

- When a star "dies" it can do many different things. It can form a neutron star, expand to a red giant and shrink into a white dwarf, or sometimes collapse upon itself to form a black hole. This is mostly dependent on the density of the star. When massive stars, those twenty times the mass of our Sun or more die, they must either exhaust all of their excess mass or implode upon themselves and form black holes. Gravity overwhelms even the nuclear forces. The gravitational force becomes so strong that nothing can escape it, even photons of light, hence the name "black" hole....   [tags: physics science black hole]

Black Holes Essay

- Stars, comets, planets, they are all visible when you look up past our atmosphere. What if I told you that there were objects up there that you could not see, but had more gravity than an object 500 time larger than our sun. Objects, that are capable of swallowing whole planets within a split second of time. An object that would steal light right out of thin-air. These objects are more powerful than anything man made. Black holes are the most popular unknown object in science. A black hole is an area of space that has so much mass crammed in it that there is no way for an object to escape its gravitational pull....   [tags: Black Hole Essays]

Black Holes Essay

- The theory that black holes have existed is not new at all. The thought of them first started in 1783 when Rev. John Michell applied Newton’s theory of gravity to predict the possibility of so-called “dark stars.” Albert Einstein’s theory of relativity predicted in 1915 “Schwartzschild singularities.” In 1967, these were renamed “black holes.” A black hole is collapsed object (usually a star) that has become invisible and has such a powerful gravitational force that nothing, even light, can escape its surface....   [tags: essays research papers]

Black Holes Essay

- In 1916, the German astronomer Karl Schwarzchild attempted to theorize how a star could shrink to become what he called a "Black Hole". Schwarzchild predicted that our sun would have to shrink to less than two miles in radius. He also predicted that even though the sun had shrunk its mass and weight would remain the same, which means that the planets would continue on their orbits, uneffected. Schwarzchild still questioned if stars could become this compact. In 1934 W. Baade and F. Zwicky predicted that the collapse of a star, strips the atoms of their electrons, thus making it a Neutron Star....   [tags: science physics space]

Essay on Black Holes

- Black Holes      Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.      Before I begin to speak about black holes, I will have to explain what the white glowing specks in the sky are....   [tags: Space Astronomy Essays Papers]

- Black Holes Within our galaxy alone, there are millions upon millions of stars. Within our universe, there are millions upon millions of galaxies. Humans have known the existance of stars since they have had eyes. Although interpretations may have differed on what they were, they were always thought of as white glowing specks in the sky, but the mystery does not lie within what we can see, but what we can not see. There are billions of stars lighting the darkness of our universe, but the question lies in what happens when one of these enormous lamps burns out....   [tags: essays research papers]

Black Holes Essay

- Black Holes Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand black holes in detail, by thinking about gravity under fairly simple circumstances....   [tags: essays research papers]
