Strange Sound From the Sky Heard Over Batangas Philippines (VIDEO)

This week, a video of a strange sound heard over Batangas, Philippines is getting viral after being shared on social media. The strange noise that seemed to originate from the sky sounded like something is in great pain. At times the noise sounded like an animal moaning. This phenomenon has been observed in other parts of the world too and the sounds were almost the same.

What was the cause of the haunting sound? Was it an elaborate prank, the sound of aliens, or just one of nature’s unexplained howling?

Some believe these noises are a real sign of the end of the world.

Scientists tried to explain the cause of the noises. They came up with two reasons. First, according to them, what people hear is only a small fraction of the actual power of these sounds. They are low-frequency acoustic emissions in the range between 20 and 100 Hz modulated by ultra-low infrasonic waves from 0.1 to 15 Hz. In geophysics, they are called acoustic-gravity waves; they are formed in the upper atmosphere, at the atmosphere-ionosphere boundary in particular. And what might be the source of such powerful and immense manifestation of acoustic-gravity waves? The powerful solar flares and huge energy flows generated by them. The effects of powerful solar flares: the impact of shock waves in the solar wind, streams of corpuscles and bursts of electromagnetic radiation are the main causes of generation of acoustic-gravitation waves following increased solar activity.

Second, the noise may have came from the huge energy released from the Earth’s core. Intensification of the energy processes in the Earth’s core can modulate the geomagnetic field which, through a chain of physical processes at the ionosphere – atmosphere boundary level, generates acoustic-gravity waves the audible range of which has been heard by people in the form of a frightening low-frequency sound in different parts of our planet.

While both theories pointed to natural phenomenon as the originator of the noises and not some alien entities, another scientist labelled the explanations as worthless, even pseudoscientific. She siad that “science works on community principles and the community has not endorsed this explanation or even its premises.”
