Giếng Kola Superdeep: Bí ẩn nào khiến Liên Xô chôn vùi suốt nhiều năm?

Kola Superdeep Well: What mystery has the Soviet Union buried for many years? Exploring the Kola Superdeep Well - the deepest drilling project in the world (12,262 m) helps reveal the mysteries of the Earth's crust structure, temperature, rock composition and ancient microorganisms. Although it has not reached the mantle, Kola and the Bertha Rogers (USA) and Siljan Ring (Sweden) projects have brought valuable data, showing that reaching the Earth's core is more difficult than conquering space. The deep drilling journey not only challenges technical limits but also overturns many previous scientific understandings. #vettrithuc #khampha #KolaSuperdeep
