The Hum sound of Earth is real! Scientists finally unravelling the secrets of Earth

The Earth makes a strange humming sound, and for the first time, it has been reported on the ocean floor. The sound has reported in some zones in the Antarctica and Algeria, but investigators consider they can notice it all around our globe. This new study issued by the American Geophysical Union explained that it was also vibrating on the floor of the Indian Ocean.

A researcher stated that these vibrations, usually called the “hum of the Earth,” sound like the static on an old TV, but reduced down 10,000 times. This doesn’t enable some animals to hear it. Although no earthquake takes place on Earth, our planet is continuously moving. The air blows, the water flows, the ground collapses, the temperature changes, and so it goes. Researchers think some of these movements create the unbearable noise, but they don’t know which one is yet.

They have hypothesized it might be the repetition of oceans colliding, the atmosphere moving, or the fluctuations born of sea and sky alike. If experts were able to hear the sound clearer, they could discover many secrets hidden inside our planet. According to them, it could even direct them how to draw a map so aliens can find us.
A different team of researchers studying the hum in the Antarctica said in 1998 that the fluctuations are always sounding. One of them from University of California at Santa Barbara described in 2001 that these are “constant signals” that wave in a range of 2 to 7 millihertz, thousands of times lower than the range humans can hear.

Nevertheless, something is clear: all of them believe the noise is being caught more evident every time. Spahr Webb, a seismologist at Columbia University, is one of the principal researchers in the 21st century who is centred on discovering the cause of the hum. He rejected that the main reason is the communications between the atmosphere and the ground. Instead, he believes that the primary cause is the ocean waves, which bang on the sea floor “pretty much all the way throughout the Earth.”

There are moments that two different waves collide to one another, sending the vibrations they generate deep down the Earth’s crust. Additionally, there are also other waves which, instead of shocking between them, they hit the ground with enough force to create a much reaction inside the world.
