A vintage photo of a UK beach has people wondering whether time travel might exist after all.
According to many eagle-eyed Twitter users, the snap - which was taken on Towan Beach in Cornwall, England, during the Second World War - hides a time traveler using a very modern device.
The photo first stirred up conspiracy theories when Twitter user Stuart Humphryes shared it on social media back in 2018.
He captioned the picture - which shows holidaymakers lounging in the sun at the water's edge - explaining that it is of: "British war workers [escaping] to the seaside."
"This Cornish beach was photographed in September 1943," Stuart added.
See the original post below:While at first glance the photo appeared to contain a perfectly normal beach scene, many people took to the comments section to claim they saw something peculiar.
According to users, a man in the middle of the photo is bent over and using what appears to be a cell phone.

Due to cell phones not being invented until the 1980s - a full four decades after the photo was taken - many deduced that the man in the picture was in fact a time traveler.

"Er... is it just me or is this guy checking his phone... in the 1940s," one person commented.
Another responded: "Time traveler?"
Unfortunately for the conspiracy theorists, there were many others on hand to debunk their ideas about time travel. They flooded the comments section with alternative explanations for what the man could be up to.
"It looks like the Time Traveler in question is a man simply rolling a cigarette," one commented.
"I think [it] is much more simpler than time traveling. He might be looking at a seashell he found in the sand, which looks like todays cellphone gesture," another suggested.
"Looks like to me, he is reading a book, following the words with his hand," a third wrote.
"Looks like he's stoking a smoking pipe to me," commented a fourth, adding: "If he was really a time traveler w/ tech of today don't y'all think he'd be more secretive about it?"
