Forgotten Technology of the Sword of Goujian: A 2400-Year-Old Mystery | Earth Science TV #shorts

Forgotten Technology of the Sword of Goujian: A 2400-Year-Old Mystery Welcome to Earth Science TV, where we explore the mysteries of our world! In this episode, we delve into the fascinating story of the sword of Goujian, a relic of ancient technology that still baffles scientists to this day. Discovered in 1965 in a waterlogged tomb in China, the sword of Goujian is over 2400 years old, yet its blade still shines like new with two razor-sharp edges. So sharp, in fact, that one archaeologist was even severed by the blade after lightly touching it to check its sharpness. Scientists have attributed this remarkable sharpness to a special alloy called Chromium Sulfide, which was used to coat the blade. What’s truly remarkable about this sword is that Chromium is a rare and difficult-to-extract metal, with a melting point of nearly 2000°C. This begs the question: how did ancient people over 2400 years ago possess the knowledge to create such a special sword when modern humans only discovered the method to extract Chromium in 1937? This discovery raises the possibility that ancient people may have had access to advanced technologies that have been lost over time. Join us as we unravel the mysteries of the sword of Goujian, and explore what it might tell us about the technological prowess of ancient civilizations.
