Scientists reportedly discovered something unexpected while attempting to dig to the center of the earth.
Although rocks, mud, and fossils are typical findings during a dig, no one could have anticipated encountering something as spine-chilling as the unearthly screams recorded at a depth of around 40,000 feet. You can hear the bone-chilling screams here:
Back in 1970, at the height of the Cold War, the Soviet Union dug what was then the deepest man-made point on earth, which has since been given the ominous moniker "Entrance to Hell."
The digging process started when the two superpowers of the time, the USA and the USSR, sought to showcase their technological prowess in a bid to achieve the obscure feat of drilling the deepest man-made hole on the planet.
The Kola Superdeep Borehole, which is over an astonishing 40,000 feet deep, is equivalent in height to stacking Mount Everest and Mount Fuji on top of each other.
The Kola Superdeep Borehole is even deeper than the renowned Mariana Trench, which is the deepest point in the ocean and is located 36,201 feet below sea level.
The drilling project, which was located in the Kola Peninsula, spanned over 20 years and concluded in 1992 when the Cold War ended and the Soviet Union disintegrated.
Although the hole is now abandoned, scientists have recognized the priceless research they have been able to obtain about the geology and history of the earth.
Reportedly, scientists discovered deposits of nickel, copper, and even gold, as well as 14 species of fossilized microorganisms.
Nevertheless, the hole has acquired legendary status and become a subject of urban myth, leading many to now call the cavernous pit the "Entrance to Hell."
As the story goes, one of the drills broke through an entire layer of rock, revealing a searingly hot cavern that piqued the curiosity of the scientists.
After exploring the newfound discovery, scientists lowered a microphone into the hole and were perturbed by what they heard on the other end.
According to the urban myth, the researchers heard some seriously eerie sounds emanating from the pit.
Numerous individuals believed that the sounds were tormented howls from the damned.
Although the legend has never been officially verified, it has generated interest in what secrets the center of the earth might hold.
Lotte Geeven, an artist from the Netherlands, recorded the noises from a similar depth in Germany.
She noted: "All the hair on my arm stood up straight and if I hear it now again after many times it still has the same effect on me."
"The sound was like rumbling thunder," she said, "or the oncoming roar of a tornado ripping through the sky."
The Kola Superdeep Borehole has been partly filled with concrete, which means it is no longer the deepest man-made point on earth after a 40,502-foot well off Sakhalin, a Russian island.
