The mysterious city was first seen floating above Foshan in China’s Guangdong province on Wednesday, October 7, 2015. Some residents were able to capture pictures and video footage of the phenomenon.
“The footage captured by a local resident appears to show a huge city floating in the clouds,” reported Paranormal Crucible. “The apparition, which was witnessed by hundreds of shocked residents, only lasted a few minutes before completely disappearing.”
Several theories have emerged to explain the sighting including Project Blue Beam, a popular conspiracy theory that claims NASA and/or the U.S. government will attempt to use holographic image projection technology to simulate an alien invasion or the second coming of Christ. The apparitions were said to test the technology and see how people would react.
