After a vintage photo taken on a Cornwall beach in 1943 resurfaced online, people are starting to second guess themselves over whether time travel exists.
You see, in this photo, taken on Towan Beach, Newquay, people think they've spotted a time traveller hiding in plain sight.
How do they know? Well, by the looks of things, there's a man on that beach in September 1943 using what appears to be a mobile phone. You know, the device that wasn't invented until the 1980s?
Advert
The photo, which first went viral a few years ago when a guy called Stuart Humphryes shared it to Twitter, is of 'British war workers [escaping] to the seaside.'
But, if you zoom in to the man in the brown suit standing slap bang in the middle of the photo, you might see something a little unusual.
It looks like this guy is peering down at something in his hands - and a lot of people think that 'something' is a phone.
His hunched over position does look an awful lot like most of us modern day people when we're sending a quick text or scrolling through Insta.
Can you spot him?
Ever since it was first shared online, people have been analysing the photo to try and see what this man is holding in his hand - and if this one pic is the proof we needed that time travel is real after all.
"This man seems to be texting. Is he a time traveller?" asked one Twitter user after inspecting the photo.
Another joked: "Good catch. It's clearly the man in the shot is a time travelling tourist checking his mobile device."
But others had some much more logical suggestions.
"Maybe he's winding his watch," one person commented.
"It looks like the Time Traveler in question is a man simply rolling a cigarette," pointed out a second.
And a third suggested: "I'm guessing he is checking his pocket watch."
Ruin all the fun, why don't you?
A few people were less focused on the possibility of a mobile phone being used in the 1940s, and more concerned with the time traveller's outfit choice.
"Forget the call phone," wrote one Twitter user. "This guy is on the beach in a suit!!"
That's just another cause for suspicion, if you ask me.
