The universe, all existing matter and space considered as a whole; the cosmos. Credited to be 10 billion light years in diameter, the universe holds the key to life’s greatest enigmas. Popularized by H.G. Wells’ 1895 story The Time Machine, time travel has been a popular concept for science fiction literature, but can traveling through hyperspace actually be feasible method of traveling in the near future. “Einstein’s general theory of relativity allows for the possibility … [to] go off in a rocket and return before you set off,” professed by the world renowned cosmologist Stephen Hawking. Throughout centuries of research many scientist, mathematicians, and physicist alike believe time travel can be possible through things such as cosmic strings …show more content…
and black holes, however the viability of time travel could also cause numerous amounts of problems. Time travel occurs when the difference between an object's departure and arrival times in the surrounding world differs from the duration of the of the journey undergone by the object. But what exactly does the time in “time travel” mean? The answer to this question all depends on personal beliefs, however philosophy does offer 3 different beliefs; eternalism, possibilism, and presentism. Eternalist believe that all points in time, no matter how distant, are equally real. They believe that the idea of time passing and flowing is phenomenal, but not real. Thus saying, a Dodo bird exist equally as a presently existing house and that as equally as a sparrow born next Saturday, this is due to the fact that the past and future have an equal ontological status with present objects (Hunter, 3). However, possibilists deduce that the past and present are fixed and actual while the future is only possible. Meaning the future of an object can hold many different outcomes in which only one will come true (Hunter 6). Lastly the presentist who believe that only present objects are real the past was but exist no longer, and the future will but does not yet exist. With these different perspectives in mind we can now move along to the actual topic of the discussion. Black Holes Based on Einstein’s theory of relativity, Harvard physicist discovered that in the presence of a gravitational field, a clock would tick more slowly (Bonsor 2).
The experiment shows that traveling into a strong gravitational field could possibly slow time. Black holes are a good example of strong gravitational fields. Black holes consist of a point in which time and the laws of physics cease to exist and all matter is crushed known as a singularity, and through the singularity time travel can be possible. The only problem is that once you enter you can’t exit. However, it is theorized that a rotating black hole exist that could allow possible travel to parallel universes. Professed by New Zealand mathematician Roy Kerr, he theorizes that when the star collapses it does so in a rotating ring of neutrons that produce enough centrifugal force to prevent the formation of a singularity, making it safer to cross through. If such holes do exist it may be possible to exit through a white hole, in which instead of absorbing everything in does the reciprocated action and forces everything …show more content…
out. Cosmic Strings Cosmic strings are a hypothetical one dimensional defect in the fabric of space time left over from the formation of the universe; interaction could create fields of closed timelike curves permitting backwards time travel (Lewis 2). Even though cosmic strings are a new theory in the world of time travel, they can still play a critical part in the research. Theses strings weave about the entire universe, smaller than an atom and under a lot of pressure scientist can conclude that these strings have a very strong gravitational pull. By pulling 2 cosmic strings together, or one string and a black hole, it is possible to create a whole time like curve. A spacecraft could be turned into a time machine by using the gravity produced by the two cosmic strings to propel itself into the past (Bonsor 4). However, time traveling with cosmic strings would take a loop of string that contained at least half the mass energy of an entire galaxy. Difficulties Even though there has been a numerous amount of research and experiments conducted on the topic of time travel there is still some difficulties.
One of the biggest struggles with time travel is the infinite amount of paradoxes, the most famous being the Grandfather Paradox. Imagine traveling through time and getting into a fight and killing the person. At that point in time it was oblivious to you that the man you just murdered was your grandfather, but how? If a man was to go back and kill his grandfather he would’ve never been born thus meaning, he couldn’t go back and kill him so does that mean grandpa is still dead? If time travel were to occur anomalies and paradoxes would spread, all over the world. Also, along with paradoxes there is the possibility that time travel could potentially be dangerous. According to Jeff Tollaksen a professor of physics at Chapman University “Humans may not be able to time travel because traveling at the speed of light would be
lethal.” In conclusion if traveling through time was feasible, there would be a variety of ways to do it. One could use rotating black holes that would allow objects to travel to a parallel universe and exit through a white hole. While cosmic strings can rocket spaceships through time due to their high gravitational pull. However, traveling through hyperspace could be very detrimental. One could unknowingly kill their grandfather and disrupt life as we know it, or even be crushed to death by the mass amount of gravity. But this is only the beginning the opportunities to time travel are endless.
If you have ever read Einstein's Dreams, you can appreciate my dilemma. If you have not yet had the opportunity to experience this wonderful novel by Alan Lightman, I guarantee that after you read it you will expand your perception of the nature of time and of human activity. The novel is enchanting. It is a fictional account of what one of the greatest scientific minds dreams as he begins to uncover his theory of relativity.
Do you believe in time travel? Because yes it exists. I mean, just think about it, you go back and think about memories, and you plan your future, don’t you? That’s time traveling. I often go back in time by thinking back to old times when I was a kid.
Travelling through time is certainly easy to imagine. You step into the time machine; press a few buttons; and emerge out not just anywhere – but anywhen. However, in reality things aren’t quite as convenient as science fiction would suggest, as you will understand later on.
...ound by time, which includes the ultimate reality of death. Although death limits us by limiting our experiences, our lives are made more meaningful precisely because they are so short. Unlike Tralfamadorians, who cannot change history, we can look back in time and learn from the mistakes of the past. Only in this sense can we truly be time travelers: that we reflect on the past and incorporate its lessons into our present lives so that the future will be more productive.
The Time Machine by H. G. Wells was an intriguing and exciting book about a Time Traveller and his journey’s through time. In this book, the Traveller explained to a group of men who were discussing the nature of time that time was the fourth dimension; just like the three dimensions of space: length, width and height. The Traveller argued that since time was a dimension, then it stood to reason that people should be able to move along the time continuum, into the past or the future. Most of the men do not seem to believe the Traveller or his theory, but agreed that they would like to travel in time, and talked about what they would do if they could. To illustrate his point, the Time Traveller went and got a model of his time machine from his laboratory to demonstrate and later returned to detail the places, things and people he had seen in his travels with his working Time Machine. Throughout the story, the Time Traveller faced setbacks and challenges, but the book outlined how he persevered and pointed to the future mankind faced.
What is time? Is time travel possible? When nothing is changing does time still exits ? Is that really true? Are you real? Metaphysics is a branch of philosophy that is significant to us when questions and other clams bring curiosity about whether things are real or not.
So, Rowling solved the problem to her satisfaction in stages. Firstly, she had Dumbledore and Hermione emphasise how dangerous it would be to be seen in the past, to remind the reader that there might be unforeseen and dangerous consequences as well as solutions in time travel. Secondly, she had Hermione give back the only Time-Turner ever to enter Hogwarts. Thirdly, she smashed all remaining Time-Turners during the battle in the Department of Mysteries, removing the possibility of reliving even short periods in the future.
Timeline by Michael Crichton, was a very exciting book about time travel and what the 'Dark Ages'; were like. Timeline also taught about the basics of quantum physics that would make it possible to achieve such a spectacular feat. Be prepared as you read this book to leap into the horrible, dangerous would of the year 1387.
Part I: The Edge of Knowledge Chapter 1: Tied Up with Strings This is the introductory section, where the author, Brian Greene, examines the fundamentals of what is currently proven to be true by experimentation in the realm of modern physics. Green goes on to talk more about "The Basic Idea" of string theory. He describes how physicists are aspiring to reach the Theory of Everything, or T.O.E. Some suspect when string theory is completely understood that it might turn out to become the T.O.E.Part II: The Dilemma of Space, Time, and Quanta Chapter 2: Space, Time, and the Eye of the Beholder In the chapter, Greene describes how Albert Einstein solved the paradox about light. In the mid-1800's James Maxwell succeeded in showing that light was actually an electromagnetic wave.
You want to try to create something miraculous that will change the world. You create a time machine that will be able to go to the past or future. You get stuck in the future.You are in a time where civilization has taken a tremendous downfall, where you cannot understand a word anyone says to you. A time where you cannot get back because you needed time machine back. At this point most people would give up and quit. They would start to doubt their abilities as a scientist and give up on their theories and inventions. In the novel of The Time Machine, the nameless character titled the Time Traveler creates a fantastic machine that has the dexterity to travel in time. Although the time machine works as the Time Traveler states, his colleagues
There are numerous people in society who lack certain skills that they need for survival.
...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, seeing it as the present? Time travel has been a long debated subject. One such debate is, can it even be done? Many models of the big bang suggest that it can, while the theory of relativity says that it cannot be done.
Says that anything a time traveler does in the past must have been part of history all along, so even if the time traveler has an influence on the past, it is impossible for anything the time traveler does to "change" history. So, if, any attempt by the time traveler to kill one of his ancestors before they became a parent would always fail for whatever reason (the gun would jam, or the time traveler would just have a change of heart)
Humanity’s knowledge of many things are limited, and while we know that some things are infinite, our mind cannot comprehend infinity itself. There is so much in this universe that is unknown, so many things that cannot be explained, for example, Stonehenge, Gate of the Sun, and The Great Pyramid of Giza, amongst others. There is no way for us to pinpoint the beginning or the end, space and time are perceived as infinite which means that anything that can happen will happen or has already happened. Time is something that is relative, no one experiences it the same way, just as no one experiences color and taste the same way. In our planet time exists in one form, it flows forward, but because of our limited knowledge of things outside of our solar system there is no way to know how time works outside of it.
It is difficult to guess where or how society is going to end up in the next couple of hundred years. Fortunately, in H. G. Wells novel, “The Time Machine,” the readers get a perspective of how the Earth could possibly look like in the year 802,701. In the novel, it is evident that humans are no longer the humans we see in today’s world. Instead, they have evolved into two different groups of people: The Eloi, being the group that stayed on the surface of the Earth and the Morlocks who live underground. At first impression, it seems that society has undergone a form of communism as the Eloi live their lives in a calm and worry-free state.
