Skip to comments.Searching for Time Travelers, Scientists Look to Social Media

Time travelers, if they exist amongst us, have yet to betray their period-hopping ways online, according to a fun, new study aimed at finding visitors from another time, based on their digital footprints.
Theoretically, the idea of time travel forward in time should be possible according to Einstein's General Theory of Relativity. In fact, scientists have already sent teensy particles called muons forward in time. But sending a large object, such as an entire person, into the future remains in the echelons of science fiction, for now.
Even so, over a summer poker game, Robert Nemiroff, an astrophysicist at Michigan Technological University in Houghton, sparked an amusing discussion with his students by asking: If time travelers were living in our midst, would they leave traces of their presence online?
The researchers chose two recent events the March 2013 election of Pope Francis to lead the Catholic Church, and the sungrazing Comet ISON, which was first spotted in September 2012 to search for premature online references to time travelers. Perhaps careless time travelers made mention of Pope Francis or Comet ISON on Twitter or Facebook before they were supposed to know about them, the researchers said.
"The Internet is essentially a vast database, and I thought that if time travelers were here, their existence would have already come out in some other way, maybe by posting winning lottery numbers before they were selected," Nemiroff said in a statement.
Nemiroff and his students combed through results from search engines, such as Google and Bing, and social media sites, including Facebook and Twitter. Ultimately, their hunt came up empty.
"In our limited search we turned up nothing," Nemiroff said in a statement. "I didn't really think we would. But I'm still not aware of anyone undertaking a search like this."
The researchers did find one blog post that mentioned a "Pope Francis" before Jorge Mario Bergoglio, then-Archbishop of Buenos Aires, was elected to lead the Catholic Church, but they think the reference was accidental, rather than a message from a time-traveling visitor.
Nemiroff and his students even created their own special blog post in September 2013 that asked potential time travelers to email or tweet "#ICanChangeThePast2" or "#ICannotChangeThePast2" a month earlier, on or before August 2013. But, they again found no signs of time travel.
Still, Nemiroff, whose research typically covers more serious topics such as gravitational lensing and gamma-ray bursts, said the study, while focused on a seemingly far-out concept, was an enjoyable undertaking.
"I'm always doing stuff on space and time," he said. "This has been a lot of fun."
Nemiroff said the study was conducted during his students' own time, and without the use of any grant funding.

Well, apparently if you fly east around the world on a jet plane, you can travel into the future by 59 nanoseconds. Scientists claim that Sergei Krikalev’s tenure on the Mir space station made him travel into the future by one-fiftieth of a second. Very infinitesimal time dilation though . . .
Take me to 1980 and make me invest in Bill Gates and that Steve guys businesses, hopefully they were out of the garages by then
Paging John Titor! Please pick up the white courtesy telephone.
crap! now I have to go read the website
There ya go!
The interesting part is about CW2 but his timeline is a bit off.
Art Bell had a guy that was intriging.
I cannot recall his name.
“The Vulcan Science Directorate has determined that time travel is impossible”
I wrote this post next Thursday.
thanks will be in order
If I time traveler REALLY wanted to do us a favor.......
I can’t go back and tell you that. What I can tell you is that the Pittsburgh Pirates will win the 2014 World Series. Also, Leon will get larger.
I caught Art Bell once many moons ago, freaky $h!t...
” Me, John, big tree! “
Tell me about it. I tried red sun energy and blue energy created from microwaving Jiffy Pop.....that didn’t work at ALL and the fire department wasn’t to happy either.
It must mean that our Civilization did not progress enough and apparently went belly up. So no time travel or anything else!
I can understand the theory behind this. It takes a lot of energy to dismantle a person and transport them via transporter/matter-energy conversion to another location - in space or in time.
You could much more easily use the same concept and add energy variations or matter changes to alter data flows in the internet, sending messages.
Why go back in time and tell your past self not to date someone, when you could send yourself an email with incriminating information that would make you break up with them or avoid them?
It’s a great sci-fi concept.
Obamacare doesn’t cover time travel related injury or disease, so nobody does it.
Trouble is that it's an early prototype....and only works in 2 dimensions...
Here it is printing something out from the past.....
...see ..it's printing out from the slot in the top oif the machine.
What a surprise! It is a wasteland of vapid people looking for some sort of reassurance their lives matter.
Why would anyone traveling in time bother with such drivel?
if I would want to communicate to my teen self to prepare for Yahoo, Apple, IBM, Amazon ect....I’d need a time traveling mailbox.
Kill time waiting for the bank to open
I am a time traveler. I’ve been posting about it on FR since 2003 then 2020 since next year a week from yesterday last week in 1723. Do I have to post a captioned cat picture to get taken seriously.
I liked this when I saw a photo of a guy with it on a protest sign:
We Want Time Travel!
When Do We Want It?
It Doesn’t Matter!
Every time I time travel I lose my luggage.
Don't we all do this now, day by day, hour by hour, minute by minute, second by second?
I am surprised they did not look into those “time traveler” callers who used to call in to the old Art Bell Radio show professing to time travel.
If time travel was possible we would have l
known since day 1.
Here's an explanation of time dilation that I wrote myself a few years ago. Hope it makes sense. The graphic I found on the Web.
First, from Wikipedia: "One second is defined as 'the duration of 9192631770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom'..."
Now imagine, instead of a vibrating 'caesium 133 atom', we have a beam of light bouncing back and forth between two mirrors within a vertical tube. Now let's say, for the sake of argument, that it takes precisely 'one second' for the light beam to reach the top mirror (tick), reflect off it, reverse and reach the bottom mirror (tock).
Now let's say the light tube, or 'light clock', is resting on a flatbed train car, and on the flatbed is an observer who we will call "Observer A". To Observer A, who is moving along with the train and is therefore 'at rest' with respect to it, the light beam simply travels from the bottom of the tube *vertically* to the top of the tube and then straight back down again. From the relationship, speed equals distance over time, we get time equals distance over speed. So this is then how Observer A defines time (t=distance/speed). Important to note here, is, according to theory and supported by experimental evidence, light travels at the SAME SPEED for ALL observers.
Now let's say there is an observer B standing on the embankment alongside the train watching it pass by. From this observer's point of view, or frame of reference, the light beam does not simply travel vertically up and down but rather in a slanted or diagonal path, since the train is in motion, let's say from left to right as Observer B sees it. Now since the light beam travels a diagonal path between tick and tock, again, from OB's stationary point of view, the light beam therefore is traveling a LONGER distance (from OB's perspective). Therefore, since the light beam is traveling a longer distance (from OB's perspective) AND since light travels at the same speed for all observers, the light beam MUST take a longer time to bounce between the two mirrors (tick-tock). Therefore, the two observers (A and B) do NOT agree on what a "second" is.
The mathematical relationship between the two paths is based on the Pythagorean Theorem for right-triangles that many of us used in high school.
If time travel were a scientific possibility, rather than a device of fiction, how could you magically find the earth when you got there? It is orbiting the sun, which is itself orbiting the galactic center, which may also be moving.
It is a reality. It's been proven with twin atomic clocks, one aboard an airplane, the other on Earth. The first such experiment was carried out back in 1975. The time was very small, but it was real. The effect is also used in GPS satellite communications. However, in both of these and other similar cases, there are TWO sources for time dilation. One is caused by the high speeds involved, the other by the gravitational field of the Earth. Clocks tick out time more slowly in a gravity field, as they do when they are in a state of rapid motion relative to a stationary observer.
“The HafeleKeating experiment was a test of the theory of relativity. In October 1971, Joseph C. Hafele, a physicist, and Richard E. Keating, an astronomer, took four cesium-beam atomic clocks aboard commercial airliners. They flew twice around the world, first eastward, then westward, and compared the clocks against others that remained at the United States Naval Observatory. When reunited, the three sets of clocks were found to disagree with one another, and their differences were consistent with the predictions of special and general relativity.”
Of course for any significant time dilation to occur, speeds approaching that of light would be required. And that would require an almost unobtainable amount of energy, particularly for massive objects like human beings. Protons and other subatomic particles are another story.
Well gosh, I wonder if you’re thinking of the guy I heard on the show some years ago who was onto the UFOs as Time Machines trail, a la REPO MAN. He was very savvy actually ... had everything worked out. I recall particularly that when Art Bell commented that “Time is nature’s way of preventing everything from happening all at once,” he replied without hesitation, “everything IS happening all at once,” momentarily rendering Art Bell speechless.
From the Titor website’s prediction page:
What is the extent of Presidential power in 2036?
50. The office of President is far more diluted and decentralized than it is here. The powers of the national government are more defined and reside more at the county and state level.
What is the new government like in 2036 compared to the current one?
51. I think the new government is good. However, since the concept of nationally subsidized welfare is gone, most people here may not appreciate it.
Looks like we win in the future.
