The Earth is humming. Singing. Its song is ethereal and mystifying and very, very weird a rather astonishing, newly discovered phenomen[on] that's not easily analyzed, but which, if you really let it sink into your consciousness, can change the way you look at everything. Scientists now say the planet itself is generating a constant, deep thrum of noise. No mere cacophony, but actually a kind of music huge, swirling loops of sound, a song so ... low it can't be heard by human ears, [roars] churning from the very water and wind and rock themselves, countless notes of varying vibration creating all sorts of curious tonal phrases that bounce around the mountains and spin over the oceans and penetrate the tectonic plates and gurgle in the magma and careen off the clouds and smack into trees and bounce off your ribcage and spin over the surface of the planet in strange circular loops. It all makes for a very quiet, otherworldly symphony so odd and mysterious, scientists still can't figure out exactly what's causing it or why [it's] happening. Sure, sensitive instruments are getting better at picking up what's been dubbed Earth's hum," but no one's any closer to understanding what ... it all might mean. Mystics and poets and theorists have pondered the "music of the spheres" (or musica universalis) for eons; it is the stuff of cosmic philosophy, linking sacred geometry, mathematics, cosmology, harmonics, astrology and music into one big cosmological poetry slam.
