Just when you thought it was safe to get back in the digital water, the internet has found a new 'the dress'.
Is this little girl jumping into water, or underwater already?
Imgur user Maskari uploaded the holiday picture on Thursday and since then it's been viewed more than 2.5million times as the internet fights it out over who's right.
The splashes around the girl's face could be water or air bubbles, leading some people to dub the picture "waterception."
But the light makes it look like she's swimming.
A lot of people suggested the photo must have digitally altered.
Some eagle-eyed eyed commenters have noticed that the child's hair looks dry, so she must be jumping in a shallow pool, which will hopefully put the debate to rest.
But that hasn't stopped "Shrodinger's Girl" - as the picture has already become known, from almost breaking a corner of the internet.
Now we know. And knowing is half the battle.
