It is not a new phenomenon, strange eerie sounds heard from the sky, and it has been reported all over the world in recent years.
While some scientists have analyzed records of these sounds and said that they are acoustic gravity waves and formed in the upper atmosphere, what people hear is only a small fraction of the actual power of these low frequency acoustic emissions, a physics professor at the University of Saskatchewan theorized that it’s more likely electromagnetic noise emitted from auroras and radiation belts.
Then there are some theorists who claim that there is a fundamental relation between the UFO phenomenon and magnetic-vortex-gravity anomalies in the Grid.
At all, it seems that no one knows exactly the source of these sounds.
Maybe it is just a natural phenomenon that sometimes occurs in the upper atmosphere but what if huge cloaked UFOs are responsible for these sounds?
The latest strange sound from the sky has been recorded in Slovakia on September 24, 2017 and once again what might be causing the eerie sound?
