Chinese TV reports that in two separate areas, thousands of people said they saw a ‘floating city’ above China.
The first reports came from Foshan in China, followed by similar reports coming from people a few days later people in the province of Jiangxi.
Experts say the apparition can be explained as a natural mirage of sorts.
Called Fata Morgana, it’s essentially a phenomenon which involves the “optical distortion and inversion of distant objects such as boats, which can appears as skyscrapers because the images become stacked, when rays of light bend as they pass through air of different temperatures such as in a heat haze” Express reports.
Of course, conspiracy theorists have other ideas. They say it could have been a window to a parallel universe.
The Paranormal Crucible commented on a video, writing:
“[It’s] a temporal vortex, a possible parallel universe material briefly into our own reality.”
We might not know exactly what this is, but it’s certainly very spooky.
