Searching the Internet for evidence of time travellers
Here’s an interesting paper (PDF) by two physicists at Michigan Technological University who have come up with a practical methodology for finding time travellers 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 travellers.
Here, three implementations of Internet searches for time travellers 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 travellers from the future were investigated.
Unfortunately no time travellers 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.
Steven Hawkings’ similar search (video) also provided negative results.
