Can we Send Humans into the Distant Future?
‘The universe is not only queerer than we think, it is queerer than we CAN think’ – J.B.S Haldane
A hundred years ago, the idea of humans travelling through space seemed outrageous to most. Space travel, like time travel, was merely science fiction. Today, spaceflight is commonplace. Might time travel one day become commonplace too1?
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.
At a glance, the concept of time travel seems absurd. Yet given some thought, you realise the metaphorical wall between the past, present, and future is smaller than you think. Light travels at a constant velocity of about 300,000 km/s. It is common knowledge that nothing can travel faster than that speed (as I will prove later on) and therefore because your eyes are sensitive to visible light – everything you see is a light wave in some form. Because of this finite velocity of light, if we observe a star, say Alpha Centauri 4 – which is 4 light years away – we do not see it as it looks today, but as it looked 4 years ago! If you look at the Andromeda Galaxy – 2 million light years away – you see it as it appeared 2 million years ago. Just as when you look at yourself in a mirror – 1.5 metres away – the image you see of yourself is not you now, but you 10 nanoseconds ago (0.00000001s)2. In other words, you look into the past every moment of your life.
In addition, technically speaking we are all time travellers into the future. We move at a rate of 1 second at a time into the future –...

...onding research are amongst the biggest names in the scientific world. Einstein of course, who laid the foundations. Karl Schwarzschild, who was at the forefront on picking up where Einstein left - Frank Tipler, who devised one of the first models of a time machine; and inspired a generation – Kip Thorne who opened the possibilities of wormholes in the fabric of space-time – and Stephen Hawking, who has explicitly shown a repeated interest in the topic. Even then that’s just to name a few! In the coming chapters I will analyse their work, and investigating whether in principle it is realistically possible to build a working time machine, given our current state of technological and physical progress as a civilization.
We will start at the beginning, before Einstein – at base camp: the dream of time travel itself and the pathbreaking science fiction of H.G. Wells6.
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.
For the Science Reader project, I read Black Holes, Wormholes, and Time Machines by Jim Al-Khalili. Interested in time travel and the secrets of space, I chose this book with hopes of better understanding our universe.
...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.
In this essay I’ll be exploring various concepts of women and will deeply criticise the way women are seen and portrayed through advertising. My primary resource I’ll be referring to throughout this essay is a book called ‘Ways of seeing’ by John Berger, which highlights the role women during the early renaissance and onwards. In addition to this I will explore the various beliefs of women from a wide range of secondary resources, and will include references from books, websites, and various images to help clarify my statements.
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.
In an effort to legitimize all subcategories of sexuality considered deviant of heterosexual normatively, queer theory acknowledges nontraditional sexual identities by rejecting the rigid notion of stabilized sexuality. It shares the ideals of gender theory, applying to sexuality the idea that gender is a performative adherence to capitalist structures that inform society of what it means to be male, female, gay, and straight. An individual’s conformity to sexual or gendered expectations indicates both perpetration and victimization of the systemic oppression laid down by patriarchal foundations in the interest of maintaining power within a small group of people. Seeking to deconstruct the absolute nature of binary opposition, queer theory highlights and celebrates literary examples of gray areas specifically regarding sexual orientation, and questions those which solidify heterosexuality as the “norm”, and anything outside of it as the “other”.
Since the beginning of time itself, man has been dreaming of time travel. The current model of physics shows no obvious doubts towards the possibility of time travel, which leaves many questions (“Quantum Time Travel”). If the quarrel for time travel holds any truth, how will man manifest the means of going about it? Before the theories set forth by the men and women in the scientific community can be understood, one must have at least a general knowledge of the basics behind quantum mechanics, as well as the estimable; Einstein’s, theory of space-time. Also, in a world where time travel occurs, there is the possibility of a paradox, or impossible situation caused by the travelers’ actions. Many answers to the paradoxes have been set forth by notable people. Possibly the most widely accepted theory of time travel, Einstein’s black hole theory, still holds prevalence to this day. Some other theories have come to light recently, and most are yet to be disproved.
The first three chapters of A Brief History of Time cover a variety of topics. In chapter one, Stephen Hawking tries to provide a single theory to describe the entire universe. Chapter two describes some of the ideas that scientists, mathematicians, philosophers, and physicians of the past had about gravity and theories of motion. The third chapter in the book talks about the work of many scientists of the past concerning whether the universe is expanding or not. In each chapter, Stephen Hawking describes several different things to solve the huge idea of the entire universe.
This disproves time because if time was tangible then it would have to be constant and apply to all things at once rather than only affect things based on perspective. One of the reasons why time is relative is due to the fact that on a cosmic scale time is determined by isolating a section of space and then using a relationship between a number of parts like a solar system to determine the clock for that section.The reason why time is determined like this on a cosmic scale is due to the fact that the universe is constantly expanding infinitely which creates the paradox of certain parts being older than others but equally as old because they are part of the same universe. Another reason why time is relative is due to the fact that similar to a DVD when a movie is being watched
The concept of time traveling has been researched by scientist for a long time, dreaming to one day make it happen. Even being this a very difficult topic, this dream has inspired a lot of novelists and directors in different works and stories that has left a mark in the history of novels, movies and in our minds. But the science of time travel is not something that you could leave behind while writing these kind of stories, in every time-travel movie the main character’s actions affects the normal chronology of the story changing the events that may happen in it and creating what is called another reality of events or paradoxes in the timeline. In the movie “Twelve Monkeys” the travel of the main character to the past in order to discover the reason of the deadly virus led to a series of paradoxes that affected the future. In this essay I’ll try to explain each of the small paradoxes that compose the big paradox of the movie.
...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.
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.
Herbert George (H.G.) Wells’ 1895 scientific romance novella, The Time Machine, is considered to be one of the forerunners of the science fiction genre. Whilst the story was not the first to explore the concept of time travel, it is quite significant for its pseudoscientific account of how time travel could perhaps occur, this interpretation has shown to be quite influential to numerous productions in both media and literature. Wells explores a number of themes throughout this novella, however there are three prominent ones, the relativity of time, social Darwinism and evolution, and capitalism. These themes explore concepts which are relevant to society and creates connections with the intended 19th century audience.
