Experts have put forward a rational explanation for strange sounds, recorded around the world. Physics professor Jean-Pierre St. Maurice said that the source of these sounds can be so-called "natural radio emissions."
"If we had radio antennas instead of ears, they heard a great symphony, composed of strange noises coming from the planet. They sound like background music in science fiction films, but this is not science fiction. Natural radio emissions are real, though poorly understood. "
"For example, radio waves have the eerie sound of lightning," — added NASA. Earthquakes can also produce the sounds, according to seismologist Brian stump from Southern Methodist University in Dallas.
