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.
