For many years time travel was the stuff of science fiction. This was all just part of the world’s imagination until recently. Scientists now believe that the current laws of physics allow us to travel though time. They believe that we can now travel back to see our founding fathers sign the declaration of independence. We could travel to 2999 to witness the birth of the next new millennium. Such travel would require a machine capable of withstanding great pressures and incredible amounts of speed. The act of actually traveling though time is for the most part, agreed upon, but the implications of such travel is not so decided upon. Many different theorists have different views of what could happen and some go, as far as to say that if we did travel to the past, we would end up in a different universe that is a replica of this one. One of the most basic concepts is that of Dilation, a stretching of something. Some scientists believe that the main gateway to the past or future is a wormhole. Einstein’s general relativity theory explains about universal constants, this is important to understand the concepts of travel at light speed. Traveling to the past could create problems if someone tried to change something. This is a paradox. A few of these paradoxes are explained through the use of quantum mechanics. Sailing though the cosmos at the speed of light with no time passing us by, moving throughout time to witness the ancient Egyptians create their masterpieces. This is an exciting concept that we could actually formulate and make happen.
Before the time of Einstein, Newton and other great investigators thought of space as an infinite expanse in which all things exist (Hewitt 213). We are in space and we live in it along with all of the planets and stars. It was never clear if the universe exists in space or space exists in the universe. Dose space exists outside the universe or only within the bounds of it. The similar question, does the universe exist only in time or does time only exist in the universe? Was there time before the universe, and will there be time after it ceases to exist? “Einstein’s answer to this is that time and space only exist within the universe. There is no time or space ‘outside.’(Hewitt 213)” Einstein said that space and time are two separate parts of a whole called space-time (Hewitt 213). To understand this, consider our presen...

... all his work. His younger self could reproduce the paintings and profoundly and irrevocably affecting the future of art. This would involve no creative energy by the “inventor.” The reproductions would exist because they are copies from the original and the originals exist because they are copies of the reproductions. No creative energy would ever have to be put forth to create these masterpieces. Because of the chronology principal time travel, by some, has been ruled out.
The cosmos await us, and the history of our world is at our fingertips. Would we use this great power for good, bad, and wealth? All we have to do is get in our spaceship, set sail for the nearest wormhole, and hope for a little luck, and we can witness things only told in stories. Only the traveler can decided what he or she wishes to go back for. The theories today state that traveling through time is possible, however they do not say what could be the repercussions of our actions. This great frontier awaits us; we have the knowledge, and are slowly but surly developing the technology. Only time will tell when time itself no longer rules our lives as one of the chief amendments of the universal constitution.
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.
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.
At his later years of life he got a wife and had two little girls. He was still the same artist, he was before. His past helped him out a lot. It made him work a lot harder to achieve his goals cause as a young child he didn't put much effort into anything unlike now. During his life he accomplished many different things, for example, he got one of his paintings in a museum. He

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.
If a two-way communicator existed across time for this to be achieved the two metaphysical considerations must be met. Firstly, Lewis highlights the that “time is one dimension of four”, in the fourth-dimensional world, suggesting that time is just as perceptible as any place and potentially where the time traveller will send the message. Second, fourth-dimensional spectrum also considers causation and possible reverse causation, that is there must be awareness for earlier events to be causally dependable on the future events, and therefore how communication will take place between two different times. Lewis argues that his grandfather paradox can provide solidarity with the past, only if a time traveller was to travel to the past, they would not be able to make any changes that may potentially lead to them never
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.

...ess. He created both these pieces before the age of 30. Many of his art was destroyed before his death because he did not think it was perfect, and he didn’t want anyone in the future to be able to criticize it. His idea that he was a divine being may hold some truth through his art because few have been able to achieve what he did with the tools he had to work with. Everything he made could not look like any other previous work of art and his unending chase for individuality changed Renaissance art forever.
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.
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 evidence that they do not exist. However, no matter what one’s belief is, the existence of wormholes still makes you wonder…
The space that surrounds is not merely the universe is not merely ideas of human minds.
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.
On the theorectical side, as Mike Garrow notes, special relativity suggests that all of spacetime exist in an eternal 'now' because the finite speed of light means there is no access to information - including notions of when someone else's 'now' is - faster than light can carry it. So, on the one hand, all of history is already written out and so you could contemplate reach back to points in spacetime that existed prior to your local 'now'. On the other hand, light only propogates 'forward' in spacetime ergo without adding exotic information carriers such as tachyons into the mix there is nothing that actually enable the reaching back to occur. The past is blocked by the light cone in Minkowski's spacetime. (Light cone).
