Strange Sounds Heard In The Sky
Since 2011, people all around the world have been reporting strange noises that appear to be coming from the sky.
The sounds, many of which wind up in videos posted to YouTube, range from a low hum, to a loud, horn-like droning, to explosions powerful enough to set off car alarms. While some of these videos have since been proven to be hoaxes, many of the events were recorded by multiple witnesses.
People from all corners of the internet rushed to provide their own theories on the source of the sounds. Some believe them to be part of a viral marketing campaign (though, with the sounds ranging from 2011-2014 and originating across the globe, this seems unlikely). Others claim the sounds are related to HAARP, a government program designed to study the ionosphere, which is often claimed by conspiracy theorists to be a secret weather manipulation project.
A few scientists and skeptics have chimed in with their own explanations. The humming or horn-like sounds could be the result of natural phenomena related to shifting gravitational poles, electromagnetic fields, gasses being released from the earth, or even things as simple as distant construction machinery, planes, and trains. The louder, more percussive noises, almost all of which were reported in the winter in cold areas like Toronto and the northern United States, could be caused by cryoseisms, or ice quakes. This phenomenon occurs when water inside the earth rapidly freezes, causing the nearby rock and soil to suddenly crack.
Conspiracy theorists, seismologists, geologists, and skeptics continue to debate back and forth, while hoaxers continue to post fake videos of the phenomena. Now and then, what appears to be a genuine occurrence crops up. One thing remains certain: Something is causing a lot of noise.
