What Is Time Machine?
Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically using a hypothetical device known as a time machine. Time travel is a widely-recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. Wells‘ 1895 novel The Time Machine
Is time travel possible?- NASA ANSWERS
“Time travel is one of my favorite topics! I wrote some time travel stories in junior high school that used a machine of my own invention to travel backwards in time, and I have continued to study this fascinating concept as the years have gone by.
We all travel in time. During the last year, I’ve moved forward one year and so have you. Another way to say that is that we travel in time at the rate of 1 hour per hour.
But the question is, can we travel in time faster or slower than “1 hour per hour”? Or can we actually travel backward in time, going back, say 2 hours per hour, or 10 or 100 years per hour?
It is mind-boggling to think about time travel. What if you went back in time and prevented your father and mother from meeting? You would prevent yourself from ever having been born! But then if you hadn’t been born, you could not have gone back in time to prevent them from meeting.
The great 20th century scientist Albert Einstein developed a theory called Special Relativity. The ideas of Special Relativity are very hard to imagine because they aren’t about what we experience in everyday life, but scientists have confirmed them. This theory says that space and time are really aspects of the same thing—space-time. There’s a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space.
Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won’t notice this effect until you return to those stationary people.
Say you were 15 years old when you left Earth in a spacecraft traveling at about 99.5% of the speed of light (which is much faster than we can achieve now), and celebrated only five birthdays during your space voyage. When you get home at the age of 20, you would find that all your classmates were 65 years old, retired, and enjoying their grandchildren! Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years.
So, if your journey began in 2003, it would have taken you only 5 years to travel to the year 2053, whereas it would have taken all of your friends 50 years. In a sense, this means you have been time traveling. This is a way of going to the future at a rate faster than 1 hour per hour.
Time travel of a sort also occurs for objects in gravitational fields. Einstein had another remarkable theory called General Relativity, which predicts that time passes more slowly for objects in gravitational fields (like here on Earth) than for objects far from such fields. So there are all kinds of space and time distortions near black holes, where the gravity can be very intense.
In the past few years, some scientists have used those distortions in space-time to think of possible ways time machines could work. Some like the idea of “worm holes,” which may be shortcuts through space-time. This and other ideas are wonderfully interesting, but we don’t know at this point whether they are possible for real objects. Still the ideas are based on good, solid science. In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built.
I am confident time travel into the future is possible, but we would need to develop some very advanced technology to do it. We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy. Time travel to the past is more difficult. We do not understand the science as well.
Actually, scientists and engineers who plan and operate some space missions must account for the time distortions that occur because of both General and Special Relativity. These effects are far too small to matter in most human terms or even over a human lifetime. However, very tiny fractions of a second do matter for the precise work necessary to fly spacecraft throughout the solar system.“
Charlotte Anne Moberly and Eleanor Jourdain
The Petit Trianon in 2005, where the incident purportedly took place.
The Moberly–Jourdain incident, or the Ghosts of Petit Trianon or Versailles (French: les fantômes du Trianon / les fantômes de Versailles) refers to claims of time travel and hauntings made by Charlotte Anne Moberly (1846–1937) and Eleanor Jourdain (1863–1924). In 1911, Moberly and Jourdain published a book entitled An Adventure, under the names of “Elizabeth Morison” and “Frances Lamont”. Their book describes a visit they made to the Petit Trianon, a small château in the grounds of the Palace of Versailles where they claimed they saw ghosts including Marie Antoinette and others. Their story caused a sensation, and was subject to much ridicule.
“Chaplin’s Time Traveller”
A still from The Circusappearing to show a passer-by talking on a cellphone
In October 2010, Northern Irish filmmaker George Clarke uploaded a video clip entitled “Chaplin’s Time Traveller” to YouTube. The clip analyzes bonus material in a DVD of the Charlie Chaplin film The Circus. Included in the DVD is footage from the film’s Los Angeles premiere at Grauman’s Chinese Theatre in 1928. At one point, a woman is seen walking by, holding up an object to her ear. Clarke said that, on closer examination, she was talking into a thin, black device that had appeared to be a “phone“. Clarke concluded that the woman was possibly a time traveller. The clip received millions of hits and was the subject of televised news stories.
Nicholas Jackson, associate editor for The Atlantic, says the most likely answer is that she was using a portable hearing aid, a technology that was just being developed at the time. Philip Skroska, an archivist at the Bernard Becker Medical Library of Washington University in St. Louis, thought that the woman might have been holding a rectangular ear trumpet. New York Daily News writer Michael Sheridan said the device was probably an early hearing aid, perhaps manufactured by Acousticon.
Present day hipster at 1941 bridge opening
A photograph from 1941 of genuine authenticity of the re-opening of the South Fork Bridge in Gold Bridge, British Columbia, was alleged to show a time traveler. It was claimed that his clothing and sunglasses were of the present day and not of the styles worn in the 40s.
Further research suggested that the present day appearance of the man may not have been so new. The style of sunglasses first appeared in the 1920s. On first glance the man is taken by many to be wearing a printed T-shirt, but on closer inspection it seems to be a sweater with a sewn-on emblem, the kind of clothing often worn by sports teams of the period. The shirt is very similar to the one that was used by the Montreal Maroons, an ice hockey team from that era. The remainder of his clothing would appear to have been available at the time, though his clothes are far more casual than those worn by the other individuals in the photograph.
Debate centres on whether the image genuinely shows a time traveller, has been Photoshopped or is simply being mistaken as anachronistic. The “Time Traveling Hipster” became a case study in viral Internet phenomena in museums which was presented at the Museums and the Web 2011 conference in Philadelphia, Pennsylvania.
The story of Rudolph Fentz is an urban legend from the early 1950s and has been repeated since as a reproduction of facts and presented as evidence for the existence of time travel. The essence of the legend is that in New York City in 1951 a man wearing 19th-century clothes was hit by a car. The subsequent investigation revealed that the man had disappeared without trace in 1876. The items in his possession suggested that the man had traveled through time from 1876 to 1950 directly.
The folklorist Chris Aubeck investigated the story and found it originated in a science fiction book of the 1950s, A Voice from the Gallery by Ralph M. Holland, which had copied the tale from “I’m Scared”, a short story by Jack Finney (1911–1995), from which the Fentz tale originated.
Between 2000 and 2001, an online bulletin board user self-identified as John Titor became popular as he claimed to be a time traveler from 2036 in a military mission. Holding the many-worlds interpretation as correct and consequently every time travel paradox as impossible, he stated that many events which occurred up to his time would indeed occur in this timeline. These included a devastating civil war in the US in 2008 followed by a short nuclear World War III in 2015.
In the years following his last posts and disappearance in 2001, the non-fulfilment of his specific predictions made his popularity decrease. Criticism has pointed out flaws in Titor’s stories and investigations suggested his character may be a hoax and a creation of two siblings from Florida.
To date, the story has been retold on numerous web sites, in a book, in the Japanese visual novel/anime Steins;Gate, and in a play. He may also have been discussed occasionally on the radio show Coast to Coast AM. In this respect, the Titor story may be unique in terms of broad appeal from an originally limited medium, an Internet discussion board.
Bob White / Tim Jones
Similar to John Titor, Bob White or Tim Jones sent an unknown number of spam emails onto the internet between 2001 and 2003. The subject of the emails was always the same, that the individual was seeking to find someone who could supply a “Dimensional Warp Generator.” In some instances, he claimed to be a time traveler stuck in 2003, and in others he claimed to be seeking the parts only from other time travelers. Several recipients began to respond in kind, claiming to have equipment such as the requested dimensional warp generator. One recipient, Dave Hill, set up an online shop from which the time traveler purchased the warp generator (formerly a Hard Drive Motor), while another Dave charged thousands of dollars for time-travel “courses” before he would sell the requested hardware.
The name “Bob White” was taken from an alias that the second Dave used when responding (a reference to the “Bobwhites” of Trixie Belden-fame). Soon afterward, the time traveler was identified as professional spammer Robert J. Todino (known as “Robby”). Todino’s attempts to travel in time were a serious belief, and while he believed he was “perfectly mentally stable,” his father was concerned that those replying to his mails had been preying on Todino’s psychological problems.
In his book Spam Kings, journalist Brian S. McWilliams, who had originally uncovered Todino’s identity for Wired magazine, revealed that Todino had been previously diagnosed with dissociative disorder and schizophrenia, explaining the psychological problems his father had spoken of. Todino’s time traveller was referenced in the song “Rewind” by jazz trio Groovelily on their 2003 album Are we there yet? The song used phrases taken from Todino’s emails within its lyrics.
Andrew Carlssin was reportedly arrested in March 2003 for SEC violations for making 126 high-risk stock trades and being successful on every one. As reported, Carlssin started with an initial investment of $800 and ended with over $350,000,000 which drew the attention of the SEC. Later reports suggest that after his arrest, he submitted a four-hour confession wherein he claimed to be a time traveller from 200 years in the future. He offered to tell investigators such things as the whereabouts of Osama bin Laden and the cure for AIDS in return for a lesser punishment and to be allowed to return to his time craft, although he refused to tell investigators the location or workings of his craft.
The Carlssin story allegedly originated as a fictional piece in Weekly World News, a satirical newspaper, and was later repeated by Yahoo! News, where its fictitious nature became less apparent. It was soon reported by other newspapers and magazines as fact. This in turn drove word-of-mouth spread through email inboxes and internet forums, leading to far more detailed descriptions of events.
A video uploaded in 2006 shows a Swedish man named Håkan Nordkvist claiming that he had been accidentally transported to 2046 when attempting to fix the sink in his kitchen. There in the future, he immediately met someone who revealed and proved to be himself about 70 years old, and with whom he “had a great time”. He filmed a short footage of the two smiling and hugging each other and showing the tattoo they had in their right arm. The story was reportedly a marketing campaign promoting the pension plans of the insurance company AMF.
Chronovisor was the name given to a machine that was said to be capable of viewing past and future events. Its existence was alleged by Father François Brune, author of several books on paranormal phenomena and religion. In his 2002 book The Vatican’s New Mystery he claimed that the device had been built by the Italian priest and scientist Father Pellegrino Maria Ernetti. While Father Ernetti was a real person, the existence (much less the functionality) of the chronovisor has never been confirmed.
Iranian time machine
In April 2013, the Iranian news agency Fars carried a story claiming a 27-year-old Iranian scientist had invented a time machine that allowed people to see into the future. A few days later, the story was removed, and replaced with a story quoting an Iranian government official that no such device had been registered.
Philadelphia Experiment and Montauk Project
The Philadelphia Experiment is the name given to a naval military experiment which was supposedly carried out at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, USA, sometime around October 28, 1943. It is alleged that the U.S. Navy destroyer escort USS Eldridge was to be rendered invisible (or “cloaked“) to enemy devices. The experiment is also referred to as Project Rainbow. Some reports allege that the warship travelled back in time for about 10 seconds; however, popular culture has represented far bigger time jumps.
The story is widely regarded as a hoax. The U.S. Navy maintains that no such experiment occurred, and details of the story contradict well-established facts about the Eldridge as well as the known laws of physics.
The Montauk Project was alleged to be a series of secret United States government projects conducted at Camp Hero or Montauk Air Force Station on Montauk, Long Island, for the purpose of exotic research, including time travel. Jacques Vallée describes allegations of the Montauk Project as an outgrowth of stories about the Philadelphia Experiment.
