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.
