When The Soviets Drilled the Deepest Hole in History

Описание: Soviet scientists drilled 12,262 meters into Earth's crust from 1970-1992, reaching depths where temperatures hit 180°C and finding water and fossils where they shouldn't exist. This is the true story of what they actually found, why they stopped, and how a Finnish hoax became one of the internet's most persistent myths.
