Back to the Future: Would Time Travelers Leave Online Traces?
Time travel into the future is physically possible: Einstein’s theory of special relativity predicts that the time between two events is slower for faster-moving objects. This has been experimentally proven by measuring clocks on commercial planes. But time travel into the past is trickier.
Astrophysicist and co-founder of the Astronomy Picture of the Day, Robert Nemiroff and his graduate student Teresa Wilson of the Michigan Technological University, in Houghton, conducted a search for evidence of time travelers using the Internet.

Using Twitter and Google Trends, the two researchers looked for any anachronistic mention or search query for Comet ISON before it was first discovered along its suicidal mission toward the Sun on September 21, 2012 and for Pope Francis before his election on March 13, 2013.
They also looked for mentions of Comet ISON on Nemiroff’s Astronomy Picture of the Day website. Their search for posts and queries reached as far back as January 2006.
