Recommended: Time travel

In this essay, I will discuss the possible logical contradictions time travel can create were it possible in every other sense. I will also discuss possible solutions to these contradictions in an attempt to retain that time travel is logically possible.
First, we must determine what is meant by time and time travel. Time travelling, defined by David Lewis is as follows “Any traveler departs and arrives at his destination; the time elapsed from departure to arrival is the duration of the journey. But if he is a time traveler, the separation in time between departure and arrival does not equal the duration of his journey”1. Time can be discerned into two different meanings. One meaning of the word is universal time, which is experienced by everyone and everything that is not time travelling. The other, is a traveller’s personal time which is amount of time spent living regardless of when or where they are. If one does not time travel at all, then they will live and die with their personal time, constantly progressing parallel to the universal time (they live for 80 years and die 80 years after their birth). If one does time travel, and they travel 150 years into the past, then die there (and then), …show more content…

If you travelled into the future, but not too far, met your future self and killed them before they had the chance to conceive a child, would this provide a contradiction? Whether or not the future you will even conceive a child is undeterminable unless you travelled far enough into the future to find out. You would then however, have to travel backwards to either tell the past you or carry out the murder yourself, but you have travelled into the past and occurred the same contradictions as stated previously. There doesn’t appear to be any way to confirm that the future you will conceive a child without travelling backwards. However, the logical possibility of time travel is so far

    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.

  • Analyzing McTaggart's Theory of Time

    1096 Words  | 3 Pages

    Time is a difficult topic to handle in metaphysics; many problems arise. If you support A-series, which involves change, you are left to wonder the rate at which time passes. I cannot put my support behind static time; time appears to pass and in passing change occurs. The only aspect of time that appears to stay frozen are events in the past. However, events have to change from future to present and then to past before they can become static in the past. Even though there are clear objections to theories about time, I cannot support McTaggart’s bold claim that time is unreal. I can only look at time from my perspective. Ultimately there is so much change that occurs in me and around me as time passes that I cannot view time to be unreal and I am left to disregard McTaggart’s argument.

    McTaggart takes a bold step in trying to disprove the existence of a phenomenon as taken for granted and unquestioned as breathing when he tackles the issue of time. If for no other reason, this quest is extremely daring in its scope, because he chooses to question an entity whose reality has probably never crossed most people’s minds.

    ... obstacle that most people who wish to travel in time must face—the universe can only hold a certain amount of matter in order to remain stable. The article then discusses some theories of time travel, which involves the understanding of quantum mechanics and quantum realities. The article then breaks the idea of time travel into 4 sub-theories: fate, alternate universe, success, and the observer effect. Of all the theories, I was most interested in the “observer effect” theory. The “observer effect” theory stipulates that anyone who travels into the past runs the risk of altering any important events of history. It is possible to kill a relative if traveling into the past. This article helped answer many of my questions about time travel, but I wished it would have provided the readers with more theories to help extend its belief that time travel is possible.

  • Temporal Becoming and the A- and B- Theories of Time

    2375 Words  | 5 Pages

    One way which we speak, experience and conceive of time is that time is something that flows or passes from the future to the present and from the present to the past. When viewed in this way, events which are present have a special existential status. Whatever may be the case with regard to the reality or unreality of events in the future and the past, events that are in the present exist with a capital 'E'. It can then be postulated that it is the 'present' or 'now' that shifts to even later times. If events in time (or moments of time) are conceived in terms of past, present and future, or by means of the tenses, then they form what McTaggart called the A-series (from which the A-theory of time is derived). This type of change is commonly referred to as 'temporal becoming', and gives rise to well known perplexities concerning both what does the shifting and the type of shift involved, which we will discuss later.

  • Analysis Of A New Refutation Of Time

    1600 Words  | 4 Pages

    In this short story, Dr. Yu Tsen, a Chinese spy for the German army, realizes that he is soon to be murdered by a Captain Madden and that he must pass on information of paramount importance to “the Chief” before his death. Reflecting upon his impending doom, Tsen remarks that “everything happens to a man precisely, precisely now. Centuries of centuries and only in the present do things happen; countless men in the air, on the face of the earth and the sea, and all that really is happening is happening to me…” (The Garden of the Forking Paths, 40). This immediately smacks of Borges theories on time, namely his point that time is like an ever-rotating sphere, which appears in “A New Refutation of Time.” Essentially, all the actions that have occurred and will occur take place in what is perceived as the present, and this is the moment our protagonist chooses to live

    Time travel, is it possible? For now no, but wormholes could make it a reality. Wormholes are a much unknown part of the universe they have been theorized to be used for time travel based on Einstein’s theory of relativity, which states that any mass curves space time. If they are found to be used for time travel they could cut down the amount of time needed to get to another universe and would create great leaps in science.

  • Time Travel: The Special Relativity Theory Of Space And Time

    1365 Words  | 3 Pages

    Scientists observe that time travel is a phenomenon that all of humanity experiences. To illustrate, I have moved forward from last year and so have others. Everyone travels through time at a rate of one hour per hour. The true question behind the time travel conundrum is if we can travel faster or slower than the normal rate of one per hour. One of the greatest minds of the 20th century, Albert Einstein, developed a theory to explain time. The Special Relativity theory posits that space and time are sides of the same coin: space-time. The speed limit of all things that travel through the space-time continuum is 186,000 miles per second or 300,000 kilometres per hour. Light travels at the speed limit in an empty space. The theory goes on to say that as an object travels through space-time relative to

  • Unstuck in Time: Billy's Dilemma with Time Travel

    726 Words  | 2 Pages

    Not only can time travel affect one's closest affiliates, but it also affects the way onlookers perceive the adventurer. As Billy’s gift of time travel began one day without warning, he was left baffled and bewildered. On top of this, it began when he was at war, which is not exactly a time or place to take a moment and reflect. Billy refers to his first instance of time travel as becoming “unstuck in time” (Vonnegut 43), and the first witnesses of his abnormal behaviour are his fellow soldiers. Billy is walking through the forest and stops to rest against a tree when his mind starts dashing and suddenly he is everywhere but the present, until Roland Weary interrupts his travels. Weary shakes him to life and throws him in the direction they

  • Lewis Grandfather Paradox

    579 Words  | 2 Pages

    The grandfather paradox is the idea that a time traveller that visits a time prior to their conception could change the past in such a way that prevents the conception from occurring (Study Guide p.9). This is seen as impossible as it leads to a circumstance where the time traveller no longer exist, therefore the act that causes her to not exist could not have been done. The grandfather paradox assumes that if time travel is possible, you can change the past. The law of contradiction tells us that contradictory statements cannot both be true at the same time. It is a contradiction to suggest that one can simultaneously exist and not exist (by virtue of killing one’s ancestor).

    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.

  • Concepts of Time Travel

    738 Words  | 2 Pages

    Some people live their lives focused on the present. Then there are those who constantly look ahead, striving to achieve greater things in the future. Regardless of how you look at life, one thing is the same for all of us: time. Time is a train that keeps on chugging no matter what; we are all on this moving train whether we like it or not. What if it was somehow possible to get off the train and board a slower train where time moved slower? Since the train represents time, you age slower on the second train. Once you reboard the faster train, you’d be in the future relative to when you first got off the first train; this is the concept of time travel. Most people at one time or another have been exposed to this concept, though usually through television and movies. In reality, time travel is strictly a theory if not a possiblity. Albert Einstein’s theory of relativity opens the door towards the possiblity of time travel. One possible means of time travel is through black holes. On the other side of a black hole is a white hole, while wormholes connect the two. Despite criticism and lack of support, physics tells us that time travel is indeed possible and that the answers lie within the phenomena of space.
