Thanks to humans, the Earth is a pretty noisy place. We’re loud creatures — certainly more so than any other animal ever to walk the planet — and we’re even louder when we get together with other humans. But the Earth isn’t totally silent, even without noisy animals all over its surface, and scientists are trying to figure out why that is. For the very first time, researchers have captured an underwater recording of a mysterious noise that Earth has apparently be producing for eons, and they still aren’t sure why.
The sound which the planet produces is a low, steady, unceasing hum. Scientists have been attempting to record and explain the odd noise as far back as the late 1950s, with little concrete data to suggest its source. Now, new researchpublished in Geophysical Research Letters is attempting to explain why it happens, and scientists think it might have something to do with the ocean.=read more
