RESIDENTS of two Chinese cities have witnessed the gateway to a parallel universe after a ‘floating city’ appeared in their sky.

Well, that’s one possible explanation offered by conspiracy theorists for the strange event, which occurred above the Jiangxi and Foshan regions of China.

The event was captured on film and showed what appeared to be a large cityscape of dark skyscrapers floating in the clouds.

After appearing on Chinese news channels and being uploaded to YouTube, the bizarre footage has attracted a number of other conspiracy theorists offering an explanation.

One of the more common themes occurring is the belief the illusion was the result of ‘Project Blue Beam’ — a secret NASA project in which the space agency will try to start a New World Order by simulating the second coming of Christ through holograms.

“This is the Project Blue Beam by NASA preparing their mind control over the sheep people. Wake up and smell the roses,” wrote one user.

“Clearly this was an offshoot of project Bluebeam by the Chinese Government in conjunction with the US air force,” wrote another.

Another theory suggests the event was not designed here on Earth; rather it was the work of aliens from another dimension.

“I believe it’s the work of the Grays [aliens]. They probably teleported a giant city or maybe reflected it from their own dimension,” wrote one user.

While these supernatural explanations are enticing, scientists have been quick to dismiss the occurrence as a Fata Morgana — a mirage caused when light passes through at different temperatures.

What buzz kills.
