It’s a bizarre Internet phenomenon: Old pictures or videos pop up, and somebody in them looks like they’re using modern-day technology. Are we just seeing things wrong…or are these time-travelers caught on camera?

If you could go back in time, what would you do? Warn people about coming tragedies? Invest in the stock market? Or go see some random boxing match in 1995? Apparently that’s what one “time traveler” did. While watching old video of Tyson’s match against Peter McNeeley in 2016, a YouTube user spotted a man sitting ringside who appears to be taping the fight on a smartphone…which weren’t really a thing until the introduction of the iPhone in 2007. It does look a lot like an iPhone. Is it a time traveler with a smartphone? Nope. It’s most likely a digital camera. They were new to the market in 1995, and the one in the Tyson video resembles one of several made by Casio.

Not until 2010 did someone notice a time traveler in footage of the Hollywood premiere of Charlie Chaplin’s 1928 film The Circus. Included on a DVD of the movie is newsreel coverage of fans gathered for the event at Grauman’s Chinese Theatre. A woman walks by and holds a thin, black object up to her ear: It’s, “of course” a cell phone…and the woman is from the future. Filmmaker George Clarke uploaded the video to YouTube, and posited the time traveler theory. But others weighed in with a more likely idea: It’s a portable hearing aid, one of the first on the market, and developed by a company called Acousticon.

In 2010, the Virtual Museum of Canada launched an online exhibit called “Their Past Lives Here.” Included was a 1941 photograph of people gathered to witness the re-opening of the South Fork Bridge in British Columbia. Among the attendees: a man who looks like he stepped right out of 2010, complete with sunglasses, TV shirt, and modern-day hairstyle. But things are not always what they seem. Closer analysis found that the man’s sunglasses dated to the 1920s (sunglasses just weren’t very popular in the ‘40s), and he wasn’t wearing a T-shirt, but a sweater with a sewn-on emblem.
