We Dug Miles Into the Earth and Found a Lost Civilization

Ever wonder how deep humans have actually dug into the Earth? From the deepest basement under the Sydney Opera House to the mind-blowing Gotthard Base Tunnel slicing through the Alps, we’re going underground to uncover some seriously cool stuff. 🕳️🚇 We’ll even check out one of the deepest building foundations ever made — it’s like the skyscraper version of tree roots! But the real star of the show? We’re diving into the story of the deepest hole ever dug on Earth — and trust me, it’s not what you’d expect. So hit play and let’s go deep... like, really deep. ⛏️🌎 Credits Credit: CC BY-SA 3.0 https://creativecommons.org/licenses/by-sa/3.0/: Сама скважина: by Rakot13, https://commons.wikimedia.org/wiki/File:Сама_скважина(заварена),_август_2012.JPG сверхглубокая скважина: by Andre Belozeroff, https://commons.wikimedia.org/wiki/File:Кольская_сверхглубокая_скважина_crop.jpg Animation is created by Bright Side. ---------------------------------------------------------------------------...
