Scientists found signs of life 7.5 miles below ground, inside the Kola Superdeep Borehole

At its deepest point, the German hole is 500 degrees Farenheit – enough to melt any conventional microphones. Instead, Geeven used recordings from a tool that measures ground movement, and an ultrasonic sensor that measures soundwaves outside human hearing.

What she found was deep, rumbling sounds reminding her of the “roar of a tornado.” The artist concedes the recordings may be resonating data transmissions, or sounds created by the devices themselves. Knowing for sure isn’t important, she said. “Mysteries are,” she explained. “They act as engines for new thoughts and ideas.”
