Can Physicists Find Time Travelers On Facebook?

Can social media find time travelers? The short answer is: No. Robert Nemiroff and Teresa Wilson, two researchers at Michigan Technological University, thought they might.

In a study released online last week, the two scoured Twitter, Facebook, Google+ and a few other websites to find 'prescient information' - that is, tweets and statuses about current events posted before the events became current. The only way someone could write such a post, they reasoned, is if they were visiting from the future.
