Stephen Hawking`S Theories Essay, Research Paper
The oldest profession in the world is not what would be commonly accepted in
society. Before a woman had a chance to sell her body, people looked up at the stars and
wondered what they were. They made figures out of the shapes they made. As we
advanced through scientific research many other doors opened that allowed us to see what
it was the earth is existing in. Our constant need to explain what is happening comes from
our want to control. Knowledge is power, and nothing is more unexplained that the
universe. Time is interlocked and must be understood if we want to accomplish a deep
knowledge of the cosmos. Commonly it was thought that there was no such knowledge.
The author Stephen Hawking had shown many otherwise. His books give a deep history
and knowledge of how the universe exists. He also explains many others aspects of the
cosmos and puts his works in an understandable writing style.
He puts the largest accent on his studies of black holes. These are fascinating
happening and the way to understanding the universe and several others can be found
through the study of black holes. There are several features of black holes that makes
them incredibly fascinating. The first one would be the common misconception of how
noting can escape a black hole. This is true in most points. If nothing can escape them,
how does one detect a black hole? Stephen Hawking discovered a fascinating aspect using
anti-particle properties. He found that when matter is pulled into a black hole by gravity
matter is constantly being pulled apart. This causes the anti-parties of matter to be throw
away at incredible rates. This happens at consistent times. The large amount of gamma
radiation let off by this is how Mr. Hawking now finds black holes. Another interesting
concept of black holes is they are can be formed other ways than by the end of a star’s life.
Stephen Hawking and his associates found that any nuclear explosion can cause the birth
of a black hole. Hawking stated that is all the “heavy water”, a component used in nuclear
weapons, was used to create a nuclear explosion a black hole the size of earth would be
created. He also stated no one would be around to witness the creation. It would have
been caused by the implosion of earth at a massive rate and the amount of energy
produced by the nuclear explosion. This had me wondering. Stephen Hawking also stated
that is a black how small enough not to disturb the orbit of earth existed close enough to
earth that it’s power could be harnessed to produce huge amounts of energy. This made
me wonder if the same concept could be used, except with all the wastes materials on
earth. I do not know the exact physics of it all, but from Mr. Hawking explanations it
seemed like it might work. Black holes were also explained by Stephen Hawking as how
they transcended time. Apparently the massive gravitational pull creates a rip in the
space-time continuum. It is unknown what happens to matter when it is pulled into a black
time wise. All matter will be ejected into space eventually as the black hole loses itself.
The smaller a black hole, the more matter is ejected. It may be an odd happening, but
because of the larger black holes are harder to detect than smaller black holes. Mr.
Hawking stated of how if an astronaught gets pulled into a black hole the tidal forces
would stretch him into a long piece of spaghetti like person. However, his life would not
end in the black hole. Given enough time he would be eventually ejected into space as
particles. All matter in a black hole will eventually be lost into space. The smaller a black
hole is, the more matter is lost by the black hole. Stephen Hawking explained what is
thought to have happened to a black hole when all its matter is lost. The hole in the
space-time continuum would collapse and an explosion as massive as on of a supernova
would happen. It would leave the tear in time. I wondered when the explosion would
happen? Would it happen now, or ten to trillions of years from when it actually collapses.
The tear in time where would it exist? Until an actual black hole is found close enough to
us I suppose these questions will remain uninsured. Stephen Hawking explains many other
aspects of universal development in his books.
The “hot big bang” theory of how our universe was created is the commonly
accepted version of how our field of existence came to be. Stephen Hawking explains how
the eventual fall of this explanation of this theory is that the energy would be limited to the
heat of the single mass at the beginning. This would lead to an eventual massive cooling of
the universe and a lack of energy would be felt throughout space. It was also explained by
Stephen Hawking of how other universes exist in other areas. How can infinite be limited?
If our universe is infinite then how do other universes exist in other realms? It was also
said of if the big bang had not happened the exact way it did, we would not exist the way
we do now. In fact nothing would be the way it is now if the big bang would have been
cooler or if it’s expansion had not been as rapid or had slowed down by even the smallest
margin. Stephen Hawking explains this as a group of monkey’s pounding away at
keyboards. Most of what they will produce will be nothing but garbage and gibberish.
Once and a while though, they will create a masterpiece. What if our universe is the master
piece and all the others have just been garbage. Anthropology would have us think
different. It was a given example of who we can see ourselves as a rich man sees poverty
in his neighborhood. They never do. Just as a poor man hears about a booming economy,
he could say to himself “what booming economy?”. We see the universe because we are
who we are and where we are. That is the only reason we can question the facts of our
existence. Sometimes we answer questions that were never supposed to be address.
Space-time has always been in question. Time travel would give a mad unlimited
powers. He could act as a god, change the world the way he wanted. If the outcome did
not meet satisfaction, then travel back in time and re-work the problem until satisfaction.
If time travel is possible, how come no one from the future has given us the secrets to do
so. Is it because the future has not been acted out yet, or has it been and we are simply the
past and we are seeing it as the present? Time travel has been a long debated subject.
Once such debate is that of can it even be done. Many models of the big bang suggest yes
it can. The theory of relativity says that is cannot be done. The theory of relativity says
that “wormholes” do exist. Einstein called them bridges though. Stephen Hawking
explained wormholes as something that creates a bridge between two regions of space.
These wormholes are shorter than the actual distance between the two regions. Space can
be though of as a piece of paper being folder over and over itself. It could have many
layers to it. Wormholes might simply connect two regions of space that seem to be
millions upon millions of miles apart from each other. Going through a wormhole would
allow you to reach a point before you actually left. If you leave the wormhole to come
back you would come back to your point of origin before you actually left to go
anywhere. You would then be in your history. There is a lot of controversy over what
would happen to you at this point. Stephen Hawking gave many point: would you become
helpless as history took you over. You would have no control over what you did as you
would simply be acting out past that way it was supposed to be. Or would you be
completely independent in your actions. You could have control to a point. History could
rewrite itself to a point. Or would you have major repercussions upon history. If you did
travel through history why was is not written in before it happened. If one did travel
through space it would already be written in time of what happened. The example given
was what would happen if you travel back in time and killed your great-great grandfather.
This would cause a ripple in time. If this happened it would have been written in time and
you would go back in time and be unable to control yourself as you are just acting out
history as the way it is written. If you did kill your past relative you would end your life
yourself, thus making the even never happen. You still continue to exist though, so how
could you have killed him? The sheer thought of this is mind-boggling. It is a paradox of
what would happen. Maybe this is why we have not been told of how to build a time
machine. Our primitive ways and violent acts, why would we give ourselves this weapon
of infinite power? Another way of explaining time travel is that all things happen, just in
different time fields. A scientist named Richard Feynman stated that quantum theory is
simply a sum of the physics. All things happen, we simply do not expierivce them all. If
time travel was possible then it would be possible to go into a different “time slot” and see
things the way they could happen if different happenings did occur. Time travel is a
concept that should not be messed with and should not be taken lightly. If someone
traveled though time and infinite number of things could change just by the slightest
occurrence. Until we fully understand the repercussions, time travel should be understood,
but not done.
Stephen Hawking is a well known professor at Cambridge University. He has
made many advances in the understandings of the cosmos, time, and the universe. I would
recommend his writings to anyone with an open mind and with a wanting to learn.
