Please tell me this wasn’t a doctoral candidate’s thesis:

If time travelers do walk among us, they’re doing a great job of keeping a low profile on Facebook, Twitter and Google+.

New research posted online last week from Michigan Technological University summarizes a search for time travelers using social media sites like Facebook, Twitter, and Google+. Physics professor Robert Nemiroff and Ph.D. candidate Teresa Wilson from the university published the work after scouring the internet for “prescient” information, or content “that should not have been known at the time it was posted.”

The researchers were not able to identify any potential time travelers.

Well, as Bigfoot believers like to say, “Absence of evidence is not evidence of absence.”
