An essential requirement for the possibility of time travel is the presumption that future and past were somehow real. But according to one popular view only the present is real, and to suppose that the past or future are also real is to suppose that the past and the future are also present -- a contradiction. According to this sort of Heraclitean metaphysical conception, the future is genuinely open: there is no realm of determinate future fact, no denizens of the future to identify or talk about, though of course -- in the fullness of time -- there will be. Travel to the future on this view would be ruled out because there is simply nowhere to go.
The past, though, is spoken of as fixed and determinate and not subject to change. Travel into the past would appear to make it accessible in a way that would enable the traveler to effect changes -- that is, to change things that are fixed and determinate and so not subject to change. Aristotle endorsed this popular view when he said that changing the past is beyond even the power of God. It was for this reason, Aristotle said, that 'no one deliberates about the past, but about what is future and capable of being otherwise' (Nichomachean
Ethics, 1139b6).
This is called the "no destination" objection to time travel. This view rejects the possibility of travelling to future because future is non-existent, therefore there is nowhere to travel to. Travel to past is also rejected, as the traveler cannot possibly go back in time and change it.
To travel is to change position with time. Travel through space is the successive occupancy of spatial positions. Similarly, time travel requires the successive occupancy of temporal positions. But that seems to amount to either the trivi...

Travel to the past requires reverse causation. Reverse causation raises the possibility of causal loops and the attendant problems that arise, for instance, if someone were to be one of their ancestors. Although this may not be self-contradictory it does lead to intolerable restrictions on the range of possibility, and the range of efficacious choice available to an agent. Dum and Jocasta in Harrison's story, for example, cannot have a daughter. Tim cannot shoot his grandfather or press a button, though he can shoot grandfather's twin and press a physically indistinguishable button which is not wired up to send a detonating signal into the past. These empirical paradoxes arise as soon as reverse causation is allowed because reverse causation makes past times causally accessible. They are some of the intolerable consequences of countenancing time travel.
“It is an illusion we have here on Earth that one moment follows another one, like beads on a string, and that once a moment is gone it is gone forever,” (27). The Tralfamadorians also tell Billy that nothing can be changed because of the structure of how time works. When Billy asks one of the Tralfamadorians about free will, the creature responds, “Only on Earth is there any talk of free will,” (86). The people of Tralfamadore say that, “All time is all time”. It does not change the way you think.
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.
Many people often wonder what would it be like to time travel. Would it be fun or scary? Would they change the past and future or keep it the same? Would it change them as a person or break them? For Dana, one of the main characters of Kindred, she went through all of that. Kindred by Octavia E. Butler is about Dana, an African-American woman, who travels back to the antebellum South to preserve her existence in the present. When she goes into the past, she meets her ancestor Rufus, a white slave owner, and she tries to stop him from becoming a racist. Dana's efforts to make her ancestor change his ways fail because he becomes dangerous and racist. This results in Dana killing her ancestor, but this action does not affect her presence in
it was his illusion of his ideal future that made time a key dimension in
Time, to normal people moves in a straight line, on the one end, is the past forever unreachable, and unchangeable to mortal beings. The past at some point becomes the present, where all mortal beings, and everything else that exists currently resides, and on the far end of this line, there is the future, shrouded in a mist, which mortals can only vaguely predict. In contrast to what normal humans see, the peculiar children, and haunting monsters of the novel Hollow City experience both time and place quite differently. For these peculiar children in Ransom Riggs novel the past is accessible through magical loops in time, where days are repeated exponentially, these loops provide to be an essential and interesting element of the story, effectively
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.
By going back and forth between the time frames, the first being in the present and the second being in 800,000, H.G. Wells lets the reader know that the time traveller has made it back from the future by providing passages that prove he made it home, to the present, alive. However, during the time span of the novel, the time traveller from the future did not know that he was able to escape the future. This changes the point of view throughout the story, even though the main character doesn’t change. Because of the changes in the time frame, the time traveller in the present and the time traveller in the future can be considered different people. “Selecting a little side gallery, I made my essay. I never felt such a disappointment as I did in waiting five, ten, fifteen minutes for an explosion that never came. Of course the (dynamite sticks) were dummies, as I might have guessed from their presence. I really believe that, had they not been so, I should have rushed off incontinently and blown Sphinx, bronze doors, and (as it proved) my chances of finding the Time Machine, all together into nonexistence.” In this excerpt, the time traveller is speaking of his own adventure after coming back from the future. However, he makes it sound as if he were in the future. By putting interjections into the story, he changes up the storyline
Octavia Butler’s novel, Kindred, is categorized as science fiction because of the existence of time travel. This novel correlates with Gunn’s definition because it connects with the fact that Dana, a 26-year old-American woman, travels from the future where she lives in California, to the past in Maryland. She traveled from the year of 1976 to the year of 1815. Some may think that time travel is impossible, but the article, Time Travel and Changing the Past: (Or How to Kill Yourself and Live to Tell the Tale) written by G.C Goddu says otherwise. He states, “not only is time travel possible, but so is changing the world” (Goddu 17). He also uses a model to explain why he think that time travel is possible. He uses some examples to prove this. His first example, Paul at 32-years old, leaves from February 12, 1998, for the past and touches base on January 28, 1972. On this outing, in an attack of self-skepticism, he finds and murders his 3-year-old
No one can ever know for sure on if travel through time is possible, but if so, watching an event would be alright. Interfering and killed something deems as a bad idea. In conclusion, time is not something to mess with. You will never know the outcome whether is happened in the past or not.
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.
What would happen if one possessed the ability to travel through time without any limitations? What kind of person this person would become? Time travel has been one of most thrilling topics in the science fiction novels. Questions about time travel always provoke readers’ deliberate thinking about their own lives. Kurt Vonnegut’s
...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.
“The Time Machine” by H.G Wells, the Eloi had this problem. They were victims of their
When the time traveler thought of the future he made assumptions that would suggest that the in the future, society would act in a progressive manner. He believed that society would be free of disease, that the human species would be very advanced compared to the humans in his time, and that the human beings in this society would not know fear because of their advances in technology. These assumptions are soon proven false early on when the time traveler thought he “…had built the time machine in vain” (21). The Sphinx puts pressure on a progressive time by suggesting that society does not progress all the time but will eventually regress.
Time Travel has always struck close to the imagination of the minds. From H.G. Wells ' "The Time Machine" to blockbuster films like "Back to the Future" - for years, time travel was the stuff of science fiction and crazy-eyed mad men but as physicists approach the subject of time travel with new advances in scientific theories and equipment, the possibility of time travel has become a more legitimate field for scientific endeavours. This paper will argue the possibility of time travel and the positive effects that this discovery will bring forth to modern day society: technological advancements.
