Abstract
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.
