But for 200 lucky accountants from overseas, that experience could come true, well nearly. Delegates from Eura Audit International are converging on North Yorkshire for a five-day conference. Part of the jolly, sorry, important business event inevitably includes a trip to the Jorvik centre in York, where visitors are transported back in history to experience a typical York street during Viking times. The centre recreates the sights, sounds and, infamously, smells of the day, including a rather nasty smell of pee. TS has always wondered why this particular feature has been necessary, as any visitor to York city centre on a Friday night, or any other British town come to think of it, will recognise the smell immediately. Perhaps our 200 accounting chums would much prefer a night on the tiles anyway.

Time travel From Wikipedia, the free encyclopedia. This article needs to be cleaned up to conform to a higher standard of quality. This article has been tagged since August 2005. See How to Edit and Style and How-to for help, or this article's talk page Time travel is the concept of moving forward and backward to different points in time, much as we do through space . It also includes traveling sideways in time between parallel realities or universes. Unsolved problems in physics Is time travel theoretically and practically possible? Will such travel invoke paradoxes , such as often used in fiction Humans are in fact always travelling in time — in a linear fashion, from the present to the immediate future, inexorably, until death. Some theories, most notably special and general relativity , suggest that suitable geometries of spacetime , or certain types of motion in space , may allow time travel into the past and future if these geometries or motions are possible. It has been confirmed that the effects of relativistic and gravitational time dilation can cause a traveller who starts at and returns to a point of origin that remains stationary, to arrive at a time farther in the future in that reference frame than their subjective elapsed time would indicate (a constrained form of time travel into the future).

43. The Time Traveler Convention - May 7, 2005 A note time travel is a hard problem, and it may not be invented until the time travelers just hear about it from the attendees, and travel back in http://web.mit.edu/adorai/timetraveler/

If you are coming from the New York Times article: Please note that the article is somewhat misleading about the many devices that residents of East Campus have built. Amal Dorai did not build any of them. Most of the devices such as the pizza button, robot, and motorized couch were built by Adam Kraft and David Nelson. The disco dance floor is really awesome and was built by Grant Elliott and Scott Torborg. It has a webpage here A note to the News Media : We are approaching finals week and we are busy full-time students! We will not be granting any interview requests until May 16 at the very earliest. Update: The convention was a mixed success. Unfortunately, we had no confirmed time travelers visit us, yet many time travelers could have attended incognito to avoid endless questions about the future. We had a great series of lectures, awesome bands, and even a DeLorean. We regret having had to turn away visitors, but there were capacity restrictions governing Morss Hall. Thanks so much to the dozens of people who helped. Check this space for photos, commentary, and more.

44. Time Travel But then how could you have ever existed to travel back in time if you don’t exist?You would have had to have been created via autonomy. http://www.iit.edu/~bosabri/time.html

Brian's Views on Time Travel and Interdimensional Voyages Links Go Award Winning Site Time Travel T ime travel is no longer regarded as strictly science fiction. For years the concept of time travel has been the topic of science fiction novels and movies, and has been pondered by great scientists throughout history. This phenomenon is due to the principal of time dilation Imagine if you will, that you are one of the people sill alive today that was born prior to 1903, when the first airplane took flight. When you were young the idea of flying would probably have been quite exciting. Some scientists believe that we may presently be living through an identical scenario. The thing that would be so exciting however, would not be flight, but time travel. Leading scientists believe that our children will live to once again see the impossible become routine. Professor Michio Kaku of the University of New York believes that space flight may one day unlock the secret of time itself. Now that we know that it is possible to travel into the future by moving at great speeds, the next problem is how to travel in time a respectable amount without having to sit in a fast moving spaceship for years. This problem is solved by the theoretical existence of what are know as closed timelike curves, and wormholes. Timelike means that the body under consideration experiences time that increases in one direction along its worldline.2 Princeton University physicist John A. Wheeler, and Kip S. Thorne of Cal. Tech. have shown that a closed timelike curve is one way to create a kind of shortcut through space-time called a wormhole.2

You are here: BBC Space Exploration TIME TRAVEL Shaping the Future by Neil Johnson The idea of travelling forward into the future or back into the past has always fascinated science fiction writers. The 'grandfather paradox' is the argument many people use to suggest that time travel is impossible. What if you went back in time and prevented your grandfather from meeting your grandmother so that your mother was never born? Then you would never have been born... and so on. Until very recently such arguments led most scientists to believe that time travel could never exist outside science fiction. But amazingly, some interpretations of the weirdness of the quantum world now suggest that time travel is possible - at least in theory. Gravity and black holes Einstein's theory of relativity brought space and time together in a single, four-dimensional arrangement that he called spacetime. We know that we can travel forwards, backwards and sideways in space, so why not forwards and backwards in time? Four dimensions are difficult to imagine, so physicists usually suggest you think of spacetime as a rubber sheet stretched out flat. If there are no large masses around, the sheet stays flat, and so any object placed on it will move around in straight lines. But a large mass, such as the

What is time? The question is as hard to answer as whether or not time travel will ever be possible. Traveling Through Time by Clifford Pickover What is time? Is time travel possible? For centuries, these questions have intrigued mystics, philosophers, and scientists. Much of ancient Greek philosophy was concerned with understanding the concept of eternity, and the subject of time is central to all the world's religions and cultures. Can the flow of time be stopped? Certainly some mystics thought so. Angelus Silesius, a sixth-century philosopher and poet, thought the flow of time could be suspended by mental powers: Time is of your own making; its clock ticks in your head. The moment you stop thought time too stops dead. The line between science and mysticism sometimes grows thin. Today physicists would agree that time is one of the strangest properties of our universe. In fact, there is a story circulating among scientists of an immigrant to America who has lost his watch. He walks up to a man on a New York street and asks, "Please, Sir, what is time?" The scientist replies, "I'm sorry, you'll have to ask a philosopher. I'm just a physicist." Most cultures have a grammar with past and future tenses, and also demarcations like seconds and minutes, and yesterday and tomorrow. Yet we cannot say exactly what time is. Although the study of time became scientific during the time of Galileo and Newton, a comprehensive explanation was given only in this century by Einstein, who declared, in effect, time is simply what a clock reads. The clock can be the rotation of a planet, sand falling in an hourglass, a heartbeat, or vibrations of a cesium atom. A typical grandfather clock follows the simple Newtonian law that states that the velocity of a body not subject to external forces remains constant. This means that clock hands travel equal distances in equal times. While this kind of clock is useful for everyday life, modern science finds that time can be warped in various ways, like clay in the hands of a cosmic sculptor.

NARRATOR: If we could travel backwards in time, it would be the ultimate thrill-ride. All of history would be a fantastic tourist attraction. That adventure is commonplace in Hollywood where time machines are fueled by imagination rather than science. MOVIE CLIP: "This is what makes time travel possible - the Flux Capacitor." NARRATOR: But will traveling back through time ever be more than just fantasy? To find out, a scientist named Kip Thorne took physics to the limit. He was inspired by the science fiction story Contact , and discovered a way - however unlikely - that time travel might someday be possible.

Missouri State University-Mountain Grove Traveling Back in Time Missouri State-Mountain Grove Fruit Science Fruit Experiment Station History Traveling Back in Time Traveling Back in time in Missouri State Today 3(6):1, May/June, 1996 by Marilyn Odneal (photo by Kevin White) A parcel from the past was uncovered this spring at Shepard Hall, the administration building of the Missouri State Research Campus in Mountain Grove. Construction crews discovered a time capsule behind the cornerstone of the building during the renovation of the facility. The copper box was opened at a ceremony held at the Research Campus on May 2. Dr. Jim Moore, director of the Research Campus, and Dr. Larry Banks, dean of the College of Natural and Applied Sciences, led the ceremony with department of fruit science staff and Mountain Grove community leaders in attendance. According to Moore, the 1968 time capsule contained a reel-to-reel tape recording of the ceremony, a list of Mountain Grove citizens, news magazines and papers, business cards and a letter from the former director detailing the Fruit Experiment Station's commitment to the fruit industry in Missouri. "It was clear, looking at the contents of the time capsule, that some things change," says Moore. The enclosed U. S. News and World Report reported on the activities of the "Reds," while the Mountain Grove newspaper featured stories about the local young men in Vietnam.

Death and Time Traveling Speculations on the science and fiction of dying to get to the future by Jim Walker Rewritten: 25 Aug. 2001 Additions: 06 Nov. 2004 How would you like to visit other worlds, the stars and planets on the other side of the galaxy? Or how would you like to live in the future, say several thousand years from now? The impenetrable light-speed barrier and the brief life span of humans appears to prevent any entity from achieving these goals. In spite of the life span and light-speed barrier, I will describe, not only how one might get to the stars and to the future, but that one can travel there, not by traveling close to light speed, not at the speed of light, but much quicker. Instantly. Instantly Before you commit this idea to pseudoscience, what I will describe does not violate any known laws of physics. Nor will I appeal to scientific speculations on superliminal loopholes, anti-gravity, wormholes, tachyons, quantum tunneling, curved space, etc. I will, however, resort to a thought experiment using fiction as a method to explain the concept. Even with the simplicity of the physics involved, unfortunately, the technology does not yet exist to achieve practical time travel for large biological life forms like humans. In spite of this temporary limitation, the technology already exists for preserving small living things such as cells, embryos, and even small animals. In this respect, one can show that, in principle, suspending a large living being falls well within the range of foreseeable technology. To demonstrate just how time travel works requires the use of a thought experiment. Once you undergo this thought experiment, you will understand that instant time travel, indeed, can work, albeit, only in forward time.

Traveling in Time Becomes Possible Black holes can take people to new dimensions Moscow State University professor Dmitry Goltsov has recently announced about the sensational possibility to travel in time. Cosmologists discovered a new dimension that prejudiced Einstein's theory of relativity. The three-dimensional model is not actual anymore. Cosmologists believe, one may travel in time through black holes with the help of a time machine. The machine will be moving from one black hole to another, which will allow it to travel either to the relative future or the relative past. It will be easy to return to our times too. Yet, it is not known, to which extent the theory is correct - the time machine has not been invented yet. The time machine has been a very popular subject for science fiction writers for decades. Yet, it is generally believed that the idea is absolutely unreal, on one has ever dreamed about it seriously. However, scientists start talking about such a possibility already now.
