Ever since the release of Doctor Who in 2005, the Tardis has been very iconic throughout the sci-fi universe. Then the question came to mind, is Time Travel really possible? Apart from the fact that Police Boxes are all over the streets of London. However, with technology advancing each and every year and theories being developed and created, it has helped to envisage time travel. Research suggests that, although hard to believe, Time Travel may be possible. Theories such as Einstein’s Theory of Special Relativity, Tipler Cylinders, Black Holes, Cosmic Strings and Time Machines just like the Tardis. They all suggest one thing; Time Travel may be possible. But, how do they?
Einstein says that time travel to the future is possible only if a person or something was able to achieve the speed of light. Realistically, this is physically impossible to do, as the person or object has to have an infinite mass and length of 0. Despite the doubts, two scientists have extended the Einstein’s equations and

Time Machines. Time Machines just like the one you see in Doctor Who, Back to the Future, and more recently, Project Almanac. Although, very easy to understand, constructing time machines would be a rather difficult task to accomplish. In order for a time machine to exist, a form of exotic matter will need to be discovered. Exotic matters that possess peculiar characteristics such as a negative energy density or mass. If a matter of this kind were to be discovered, a time machine would bend the space-time continuum backwards until it forms a loop otherwise known as a “closed time-like curve” or CTC for short. Which, essentially means that the time machine follows a path until it reaches a point in space and time that it began at. This means that time travel is possible only towards the future after the machine has existed. These are only a few of the many theories that have been discovered up to
Movies or shows about time-travel are complicated, and never really make sense (I’m looking at you, Lost); Back to the Future guides us through potentially tricky subject matter by relying heavily – and very intelligently – on the tenets of classical narration listed above: Marty’s goals are very well-defined (to make sure his future parents meet, and then to get himself back to 1985); the chain of cause and effect is very clear: Doc Brown swindles plutonium from some Libyans → the Libyans, once they track down and shoot Doc, chase after Marty, Doc’s assistant → Marty tries to flee from the Libyans by speeding away in the DeLorean time machine that Doc has made → Marty hits 88 mph, sending him back to 1955, etc.
One day at my job as a US Air Force test pilot in the year 2023, on Area 51, I stumbled upon a lower level of the underground bunkers used to store top secret materials and projects I discovered a cylinder of high strength glass. The room was well lit, but it seemed empty and abandoned. As I approached the strange object, it became apparent that there was a door that opened and swung to the left, with a high strength steel latch on it. Once I was close enough, I realized that this machine may have been a prototype of the much sought after time travel machine that was depicted in so many movies and TV shows. The sparkling glass, the gleaming aluminum base and cap, suddenly seemed very appealing, interesting, and enticing to me. I stepped inside.
That is why Kipp consider that time travel is possible through traveling at high velocities, but later adds on, “I do not believe that goal would be reached”. Through the infinite possibility through the future, I disagree with Kipp’s comment of humans will never reach the goal because I do believe that one day in the future humanity would be able to time travel
The word “impossible” has been a controversial topic discussed for years by people who just explain why there is nothing more we can do. In the book, Physics of the Impossible, Michio Kaku takes multiple ideas and concepts from recent books or movies and he discusses how each of them could or could not exist in the future. Kaku is a theoretical physicist who attended Harvard after winning a scholarship there (preface xi). His passion for science began young in life when he entered and won a science fair, which was his inspiration (preface xi).
Ultimately it is stressed that decisions have impact on the unknown, providing comfort as it implements two principles; that undesirable future events are able to be prevented and fixed and that desirable future events are able to be created. The comforting nature of these time travel principles illustrate that the notion of control alleviates fears as sublime ‘what if?’ scenarios are made possible and attainable.
The first of the Special Theory of relativity’s affects, causes the phenomena of time dilation. Time
In this paper I will be discussing the concept of the paradox, examples from Zeno and McTaggart, and how modern science has potential solved the paradox put forth by McTaggart. Both of these paradoxes have a enormous repercussion on how objective fact about the world can be understood. I claim that McTaggart’s theory of time can be solved by modern physics as Einstein’s theory of relativity makes time a relative factor in how time is understood.
In Einstein’s curved-space-time universe, things are far more flexible. You always move into the future, traveling through time second by second, but not able to go through any faster. It is still called time travel because to move through time. It is called moving on a time-like curve through space-time. If the curve becomes too large, it loops in, causing time loops and becoming a closed time-like curve. Such phenomena is predicted by the Theory of General Relativity, that time will “loop”, resulting in a person to relive a certain part of his/her live over
The Time Traveler climbs into the seat of the time machine, takes the starting lever in one hand, and the stopping lever in the other, and hurls forward into time. As he pushes the starting lever into the extreme position, he wonders if what he is experiencing is actually happening. As he tears his vision from the clock, the Time Traveler realizes a storm is forming around him and pushes the stopping lever. The machine stumbles in the sky and the Time Traveler is flung through the air! In the novel The Time Machine by H.G. Wells, a man travels through what he believes to be the fourth dimension, time, by using a time machine he created and goes on quite an adventure in
Time Time is defined as a measured or measurable period, a continuum that lacks spatial dimensions. This broad definition lacks the simple explanation that humans are searching for. There are many scientists, philosophers, and thinkers who have tried to put time into understanding terms. The aspects of time that we can understand are only based on what we can perceive, observe, and calculate. Every day we look at our watches or clocks.
The beginning of the book is very intriguing, pulling readers into the book and making them want to read more. The book begins in the Time Traveler’s home, where he and his guests are having dinner and discussing his theories about time and time travel. When the Time Traveler tells the guests he can actually do it, they are skeptical. The Time Traveler’s colleagues bombard him with protestations and thought-provoking questions. This part of the book makes the reader wonder what the outcome of time traveling might be but it is obvious that the Time Traveler wholeheartedly believes in time travel.
Besides time travel theories on physic and philosophical, there are also paradox theories about time travel. One paradox theory is the grandfather paradox. The grandfather paradox means that if someone can go back in time and
Throughout the ages, outstanding physicists, to the movies, to some of the greatest science fiction novels of all time, have pondered the idea of time-travel. The thought of actually being able to travel to another time or universe has long since enthralled, enveloped, and overwhelmed some of the greatest minds in the history of physics. No one person can actually prove any of their theories, but a few actually make sense. Meaning that they do not violate the laws of physics. One of the main theories suggested, are wormholes. Wormholes are considered to connect two regions of flat space-time, two universes, or two parts of the same universe. There is a lot of theoretical evidence that wormholes exist, with an equal amount of
This postulate developed by Einstein has what some would call key problems and would cause uproar in conventional thinking. Things such as time now become variables when original thinking classified it as an unchanging constant. Just thinking about this prospect can be mind boggling. Time is something that everyone takes for granted as being a constant flow, just ticking away, and perpetual. But, in fact, it is something that depends entirely on space-time. How do we know that time is relative? Imagine a different kind of clock. This clock is unique because instead of a hand ticking away it is actually a beam of light bouncing between two mirrors. This would seem the most logical choice of an accurate clock because light is a constant right? As we observe the clock it ticks off at regular
Time travel has been debated for years by philosophers and non-philosophers alike. While the possibility of time travel is intriguing and alluring, I do not believe its portrayal in today’s media is plausible. In this paper, I will argue that time travel, particularly back in time, is not possible in our current world and universe.
