Earth gives off a relentless hum of countless notes completely imperceptible to the human ear, like a giant, exceptionally quiet symphony, but the origin of this sound remains a mystery. Now unexpected powerful tunes have been discovered in this hum. These new findings could shed light on the source of this enigma.

April 17, 2008, 9:08 a.m.FTA:
The planet emanates a constant rumble far below the limits of human hearing, even when the ground isn't shaking from an earthquake. (It does not cause the ringing in the ear linked with tinnitus.) This sound, first discovered a decade ago, is one that only scientific instruments - seismometers - can detect. Researchers call it Earth's hum.
Investigators suspect this murmur could originate from the churning ocean, or perhaps the roiling atmosphere. To find out more, scientists analyzed readings from an exceptionally quiet Earth-listening research station at the Black Forest Observatory in Germany, with supporting data from Japan and China.
Who knew the earth had a hum!? I wonder if it's caused by the speed at which the earth revolves etc.

April 17, 2008, 2:34 p.m.n2n it could be caused by friction as the earth rotates there is a bit of drag between the atmosphere and the earth. Theres a meterologist term for it...can't recall the name off hand.
Coriolis effect or something like that.

April 17, 2008, 9:26 a.m.No i didn't know the sun had a ring! I guess i'm not too old to learn, only problem is, it's more exciting to learn at my age now than it was when i SHOULD have been learning this stuff.
uhmm. Wait.. I don't think they even knew this stuff back then!

That's just because the sun knows the words. Always showing off! Typical Leo.

Only the sun knows the secret,
That more than human can we be, that humans truly locked, in this planetary circle......."

April 17, 2008, 10:30 a.m.Ever heard a pulsar? How about the leonid meteor shower? The universe is a giant orchestra with every object, every particle giving off a vibration. Even us.

April 17, 2008, 10:43 a.m.interesting asiide:
J.R.R. Tolkien wrote a book called the "Silmarillion" which describes the creation and history of his fiction world, "middle earth"
during the creation myth section, he describes a creator god, Illuvitar, first creating lesser Gods (angels), the Vanir, and together they cause all of creation and all of time to exist by singing in chorus. Each improvising around illuvitar. the stories tolkien then tells in his books about middle earth are supposed to be the stories written in those songs.
interesting if your in to fiction

April 17, 2008, 10:48 a.m.Except for Melkor whose dissonant melodies, all brass trumpets and shouts which tried to down out the melody of the One only to be incorporated into it, were in opposition to Illuvitar.
I read the Hobbit first and then the Silmarillion before I read the rest of the Lord of the Rings. Best way to do it in my opinion.

Not much different from a lot of the Ancient Near East texts and creation myths, not to mention the Judeo-Christian version where it's the 'word' of God, God's breath and the wind of God creating.. Lots of angels around then ;)

Thanks not2needy!

April 17, 2008, 1:25 p.m.Has anyone ever heard what one of our probes picked up from Saturn? Creepy. That's all I can say. Creepy.

April 18, 2008, 1:03 a.m.Wonder how that could be found, Mutainia?
The technology in those probes is incredible, also the tracking equipment used on earth. I've read that strange noises supposedly picked up from deep space have actually turned out to be molecules knocking together in the hardware used for detecting them!

April 17, 2008, 1:27 p.m.I found a Promotional CD that NASA distributed, at a garage sale a few years ago. (I think it was from the late 70s / early 80s.)
Quasars, Pulsars, Bleeps, Blips, Squeaks, Squawks, and assorted unearthly tracks. I used to put it on at night and fall asleep to it. There was just something really comforting within the sounds.

April 17, 2008, 2:05 p.m.I suppose they've ruled out a resonance from the magnetic field or the multitude of radio waves and frequencies that have developed over the years that permeate the planet.
Could it be Tennessee Ernie Ford from the grave?

April 17, 2008, 2:20 p.m.Actually, I have heard of this for quite awhile now.....I have seen reports of people hearing a "hum" continuously while other people around them don't hear a thing. Weird and unexplained is what they said. Somewhere near a place called Taos I believe. Interesting stuff.

April 17, 2008, 4:26 p.m.perhaps the space aliens at area 51 are attempting to contact their home planet by redirecting their ships communication area into the earth's core. the EM field being generated by the spinning magma in the middle of all the iron is creating a wave field that their signal is riding like a ship without a rudder. so it is spinning about in these cycles before heading out into space.
soon the Vogans will come for their lost citizens. perhaps 2012.

April 17, 2008, 4:32 p.m.or maybe tiny little strings are vibrating at different frequencies and these frequencies determine what everything in the universe is. and now these frequencies are changing and soon we shall all be unmade. maybe in 2012. (although David Eddings says nothing can be unmade)
