In this paper I will argue that there is a significant difference in the way time travel to the future is possible as compared to time travel from the past is possible. While there are many similarities especially in the physical act of potential time travel, the logical aspect of time travel can cause a plethora of problems. Both the differences in physical possibility and logical possibility will be compared primarily given a few interpretations established during this class.
I shall begin by establishing our interpretation of the universe in how we will time travel. First our interpretation of time travel will be using the David Lewis definition, which formally defines time travel as a discrepancy in the user’s personal time as compared

When moving from the present to the past in the both cases, the two locations will seem to move in the same rate if traveling through normal space but by entering the wormhole in lower gravity or in the wormhole at rest (relatively) you will enter the past of your destination, and if you were somehow able to return to your location of departure it would also be in the past. Traveling to the future works by just reversing which mouth of the wormhole in which you enter. Now the biggest difference is how moving to the future can work. In the case of the gravity well wormhole the difference between the rates of time passing is not constant. Therefore, if someone was to enter the past through the wormhole it is very possible to reach very far into the future. Adding on to this physically there is no way to travel back in time before the creation of the wormhole or prior to the two mouths decoupling. While there is no theoretical limit to how far in the future one could travel in the gravity well case since the rate increases for as long as the wormhole remains …show more content…
In the physical possibility of time travel and since there is some parity both can be explained using the same phenomenon. These phenomena have been proven by the laws of quantum mechanics as well as the discovery of blackholes. The only part of the physical aspect that has not been yet completely proven is the wormhole aspect due to the fact we do not yet have a way to stabilize or exit a blackhole. The logical aspects for the most part just require a particular view. Specifically, the notion that time and motion are relative, which has been proven my Einstein’s explanations of quantum mechanics, this is specifically to show the idea of personal time relative to external/world time. As well as his showing spacetime proof in which we can link our identities to our worldline in spacetime. But to travel to the time we must add the idea of compossibility and self-consistency for that to work. In addition, to avoid certain paradoxes, we must accept that the universe in which time travel is possible is strange and subject to certain oddities. Since none of these theories, the ones not proven by Einstein and the scientific community, have any concrete proof or evidence they require a more all-encompassing notion of time travel. It is for these reasons time travel to the past is significantly different compared to traveling to the
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.
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.
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.
In an open loop time travel system the time traveler can change the future by influencing the past. In “Back to the Future”, after traveling back in time 30 years, Marty Mcfly attempts to save his father's life from an oncoming car. Little does he know the car wasn't destined to kill his father, but cause his mother and father to meet. Now Marty’s mother is infatuated with Marty and he must figure out how to reverse this, and get back to the future with no plutonium left. This is a perfect example of open looped time travel because Marty was able to change the past in ways that influenced the future. We see this when Marty starts to fade out of existence because his mother no longer knows his father. If we were dealing with a closed loop system, Marty pushing his father out of the way of the car would probably have been the thing causing his father and mother to meet in the first place.
ABSTRACT: The general theory of relativity and field theory of matter generate an interesting ontology of space-time and, generally, of nature. It is a monistic, anti-atomistic and geometrized ontology — in which the substance is the metric field — to which all physical events are reducible. Such ontology refers to the Cartesian definition of corporeality and to Plato's ontology of nature presented in the Timaeus. This ontology provides a solution to the dispute between Clark and Leibniz on the issue of the ontological independence of space-time from distribution of events. However, mathematical models of space-time in physics do not solve the problem of the difference between time and space dimensions (invariance of equations with regard to the inversion of time arrow). Recent research on space-time singularities and asymmetrical in time quantum theory of gravitation will perhaps allow for the solution of this problem based on the structure of space-time and not merely on thermodynamics.
We have done a lot of research about space and have learned a lot with the technology we have. One of the main mysteries that we have not understood much is “the hole”. When I say “the hole” I mean the three main ones the black hole, white hole, and the wormhole. Each one is important in their own way, but this paper will be focused on black holes. I will briefly touch on theories that involve time travel, white holes, and wormholes.
The time travel. I won’t go into the details because time travel isn’t a real thing
... the future, life as we know it will be greatly changed. Past mistakes can be corrected, unpleasant situations can be avoided, and future knowledge can be gained at a present time. Will we find that changing the past, like what happened in Bradbury’s story “A Sound of Thunder,” will change our present life? Will going to the future bring great devastation to our present life? The idea of time travel seems very inviting and exciting, but can anyone really know if time travel will bring destruction to the present life? Will reliving the past and correcting mistakes leave men unable to learn from their mistakes? The idea of going into the future may seem like a good idea, but will it leave men with no desire to explore and experiment their ideas? Though time travel is an interesting idea, like it was to Ray Bradbury, it has the potential to destroy life as we know it.
An underlying theme present throughout the series is the possibility that our existence is not the only one. According to current theories in physics, it is entirely possible that our universe is just one of many universes f...
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.
...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.
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
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.
possibilities be? The ideas presented in this story are very entertaining and imaginative. From what I gathered while researching this novel and the time period in which it was written, the author, H.G. Wells, incorporated new ideas about science and physics into this story. It is not hard to see why this story is considered classic science fiction more than one hundred years after it was first published. This story is great because it sparks your imagination and persuades you to consider the mysteries of science and time travel.
...inning but later travels to the past from the future, the traveler has changed the past with his presence. Dowe explains this paradox by explaining that there are two different timelines, two different pasts. In the temporal timelines, if the time traveler had traveled to the past then that means he has always been in the past. In the movie 12 monkeys, the past with recording evidence from the psychologist and the death of John at the airport all existed when John traveled back. He didn’t change the past because the past is fixed, but he was just part of the past events.
