A famous painting from 1860 seems to prove that time travel is real as the woman in the image appears to be holding a mobile phone which was not invented until many years later.
The painting in question, titled 'The Unexpected One' by Ferdinand Georg Waldmüller, shows a woman walking down a rocky path with a young man on the right holding a rose.
However, it seems that the woman is too occupied to notice that the rosy-cheeked man is on bended knee, waiting to give her the flower as a declaration of his love.
In the painting, the woman is focused on a rectangular object which is placed in both of her hands.
Some claim that the object looks like a mobile phone, a device that was not invented until decades later.
While this item may look similar to an iPhone, which wasn't invented until 2007, art critics have stated that there is a simple explanation to the illusion.
The woman is thought to be reading a prayer book during her stroll rather than browsing on an iPhone as if she were a time traveller.
Gerald Weinpolter, CEO of the art agency austrian-paintings.at, explained to Vice : “The girl in this Waldmüller painting is not playing with her new iPhone X, but is off to church holding a little prayer book in her hands."
Peter Russell, a retired local Glasgow government officer, was one of the first people to take a shine to the painting, pointing out how the object could be misconstrued for something more modern than a prayer book.
He first saw the painting while visiting the Neue Pinakothek museum in Munich.
Peter told Vice: “What strikes me most is how much a change in technology has changed the interpretation of the painting, and in a way has leveraged its entire context.
“The big change is that in 1850 or 1860, every single viewer would have identified the item that the girl is absorbed in as a hymnal or prayer book. Today, no one could fail to see the resemblance to the scene of a teenage girl absorbed in social media on their smartphone.”
However, this is not the first time that a 'time traveller' has been spotted with what seems to be a mobile phone in their hands before the device was invented.
In another mind-boggling image, a 1670 painting by Dutch painter Pieter de Hooch shows a quaint domestic scene, with one of the subject's holding what looks like an iPhone.
The supposed image of an iPhone - painted centuries before the devices were first created - can be seen in the hands of a man standing to the right of the picture, according to conspiracy theorists.
