Earth hums while making 'Love' waves
A subtle and mysterious global hum has been detected by seismologists studying records from earth's most boring seismic stations.
The newfound vibration is made of two-minute to five-minute, side-to-side surface seismic waves, called Love waves.
They are named after the UK mathematician Professor Augustus Edward Hough Love, who created the mathematical model of such waves in 1911.
The discovery comes 10 years after seismologists first identified louder global oscillations that resemble the ringing of a gigantic bell.
All of the planet's natural oscillations have signatures, or modes of vibration, depending on where and how they are created by earthquakes, ocean waves or other forces.
Among the suspects for making the Love wave hum are winds, ocean waves or even the sun.
The Love wave is a mode that essentially torques the earth's north and south hemispheres against each other.
It's as if the planet is dancing the twist, says Dr Rudolf Widmer-Schnidrig of the Black Forest Observatory in Wolfach, Germany, and the Institute of Geophysics at the University of Stuttgart.

That's very interesting. I have forwarded it to my son, he loves physics and he'll be interested in how it ties in with praising God.
