In the middle of the Cold War, Soviet scientists weren't just looking up at the stars. They were looking down.
Led by Dmitri Guberman, they started drilling on the remote Kola Peninsula in 1970. Their goal was to pierce the Earth's crust deeper than anyone ever had.
The project was partly a race against American scientists. It became a journey into the unknown.
By 1994, they had drilled over 12 kilometers straight down. That's deeper than the height of Mount Everest.
The deeper they went, the stranger things became. At 9,000 meters, temperatures hit 180°C.
The granite rock there didn't shatter. It flowed like plastic around their drill bits.
Then they pulled up a core sample from 6,000 meters down. It was filled with microscopic fossils of ancient plankton.
This was supposed to be solid rock, not an ancient seabed. Their discovery rewrote geology textbooks.
They also found vast reservoirs of superheated water, trapped deep in the crust. The hole was sealed in 1994.
It remains the deepest artificial point on our planet, a silent monument to human curiosity.
