Searching the Internet For Evidence of Time Travelers 465
Hugh Pickens DOT Com writes "Here's an interesting paper by two physicists at Michigan Technological University who have come up with a practical methodology for finding time travelers through the internet. 'Time travel has captured the public imagination for much of the past century, but little has been done to actually search for time travelers. Here, three implementations of Internet searches for time travelers are described, all seeking a prescient mention of information not previously available. The first search covered prescient content placed on the Internet, highlighted by a comprehensive search for specific terms in tweets on Twitter. The second search examined prescient inquiries submitted to a search engine, highlighted by a comprehensive search for specific search terms submitted to a popular astronomy web site. The third search involved a request for a direct Internet communication, either by email or tweet, pre-dating to the time of the inquiry. Given practical verifiability concerns, only time travelers from the future were investigated. No time travelers were discovered. Although these negative results do not disprove time travel, given the great reach of the Internet, this search is perhaps the most comprehensive to date.' Stephen Hawking's similar search (video) also provided negative results."

... I did experience some kind of "reality bending", about 9 minutes prior to the earthquake that triggered the tsunami in Japan.
The date was April 11, 2011.
It was 16.07 local (Singapore) time, as I was in Singapore for a business meeting.
I was sitting in front of a computer display typing away, inside a hotel room. The desktop computer was provided by the host, and it was plugged into the net. The computer clock had just been synced with some online atomic time at noon time (some 4 hours ago).
For some reason I felt something weird, nothing moving, but I felt that something is not right. I look out of the windows (it was a high-rise hotel, and my room was in the 23 or 24th floor) and I witnessed "reality bending".
I can't really describe it, but what I saw was the window frame and the concrete pole "bend", not unlike what the "bending images" of some old vhs tapes where part of the scenes got scattered to one side.
That weird sensation only lasted a few seconds and the first thought that came across my mind was that there was an earthquake.
Since Singapore is located very near to earthquake zone, I expected that something gonna shake and was waiting to see if the shaking gonna be big and if that I have to evacuate from the hotel room.
But nothing shook.
So instinctively I look at the computer clock. It showed 16:07.
I sat there for a minute or two, waiting for some "signs" of shaking or whatever. Nothing.
Satisfied that nothing gonna happened I continued what I was doing.
A few minutes afterward, news started to trickle in over the net - a big quake in Japan, and later, a devastating tsunami.
Till now I still can't explain what exactly happened, and why my first thought after I experienced that "bend reality" was a "earthquake".

I stood on top of the WTC a few days before 9/11. I said to my friend "I wonder how they'll take these buildings down." It was a discussion on the deconstruction of it, since virtually every modern building has a finite lifespan, and will be replaced eventually. Explosive demolition was out, because it would cause too much damage to surrounding buildings, even under ideal circumstances.
Now, did the fact that we were on top (observation deck, and roof) and said something like that show precognition? Not in any sort of way. People think and say all kinds of things all the time.

You're assuming absolute positions here. In general relativity, it is equally valid to consider the Earth to be at rest, with the rest of the universe moving and rotating in a complicated fashion. But I agree that it doesn't make sense to think of time-travel only in terms of time - it's space-time that matters.
In special relativity, the only way to travel to the past that I'm aware of is through superluminal motion, but general relativity is more flexible, and allows time travel by distorting space-time in inventive ways. Perhaps the most commonly considered time travel thought experiment in GR is via wormhole. Any wormhole potentially allows time travel: even a purely spatial wormhole can be turned into a temporal wormhole by using time dialation (from acceleration or gravity) to make less time pass for one exit from the wormhole than another. So one could, for example, make time machine by making a local wormhole (this step is left as an exercise for the reader), taking one end on a spaceship and making it orbit close to a black hole for a few years, and then bringing it back. If, say, 10 years passed for one end and only 5 years for the other, then entering the "old" end would let you exit 5 years earlier. But interestingly, one could not use this time machine to travel earlier into the past than when the wormhole was first created.
Another interesting way of distorting space that has been investigated is the warp drive, which continuously distorts space around an object. This can be used both for superluminal travel or time travel by changing the parameters. The problem, though, for all these "distort spacetime to travel to the past" approaches is that to get the correct shape for the distortion requires matter with exotic properties such as negative energy density, which has never been observed.
In common for all these time travel mechanisms is that they aren't simply "POOF, and you're there", they all involve continuous trajectories in space-time, and so don't have the problem you mentioned.

They're only checking this reality? Not all the other ones as per the Many Worlds interpretation? OK, so if the many worlds interpretation is correct, and some one invents a time travel device in the future and travels back in time, then we will not find them here. You see, everything that can happen does -- Time travel into the past splits the time line as Good 'ol Doc Brown told you.
Now, time travel to the future is more than possible, you're doing it right now, and in fact, GPS has to deal with future time drift: Satellites experience less gravity so their clocks run into the future faster than ours. Just get next to a large gravitational mass for a while, and if you can survive to make it back home, you'll be further into the future than us. To the observers you're just gone in the interim.
However, time travel to the past would be more tricky. When you arrive at a past point in time the interactions you make cause the universe to split, as it does for every interaction. The time-line where the time machine will be created and you will travel back in time remains untouched, and a new series of events unfold. Unfortunately for Doc Brown's plot, you could easily prevent your mom and dad from dating and it wouldn't cause you to disappear -- Because they're dating elsewhere in another universe that you will be from in the future, thus eliminating any paradox.
One could think of the paradox resolution through predestination as well. The probability of you traveling back in time to do the split was already encoded in the state of the universe that allows you to do so. When looking at the time-line hierarchy, as a whole there were events leading up to the discovery of time travel and those universes up to those points all had probability for your splitting of them by returning to them, so by the time you got in the time machine, you had already done the things in the past. From a single time tree moving forward, as time marched forward you would see time travelers appearing and branching off from the time-lines where time travel would become possible up to and beyond the invention of the time machine, this way your single destination still has its quantum probability distribution of when and where to arrive.
So, if you are waiting for time travelers and they don't show up, it could be that they are all showing all around you in separate universes, and this is the universe from which the time machine will first be invented. In other words: You could send yourself yesterday's lottery ticket, but that ticket would exist in an alternate time and you'd remain just as poor as you are in this universe, in some other universe you may get all (or only most) of the lottery numbers correct (depending on if your interaction caused the numbers probabilities to change). If you could maintain stream of information to the past you could call yourself up, and have a conversation, and the current you wouldn't remember being called, and the past you may never get around their past self. This is no paradox in the Many Worlds interpretation.
However, I'm not convinced that interpretation is correct. It hints at mock-free will through predestination of every possible outcome, but it would mean the infinite dissipation of energy for the encoding and processing of all outcomes would be strangely detached from reality. I think it far more feasible that things like quantum "teleportation" will work out to be far more mundane than they first appear -- Hint: the "tele" in "teleportation" has to do with transmitting information, and the teleport is not faster than light... Entropy would seem to suggest that travel to the past in a single time-line would take as much (and more) energy as all the events that led up to the present. However, I have a corner of the house that's always empty the event that I'm wrong since our dreams have often proven more powerful than reality.
