Have you ever wondered how deep is the deepest hole in the world? Known as the Kola Superdeep Borehole, the deepest manmade hole humans ever dug reaches approximately 7.5 miles below the Earth’s surface (or 12,262 meters), a depth that took about 20 years to reach. Today, Kola Superdeep Borehole is still is the deepest artificial point on Earth.
If we were to journey to the center of the Earth, it would take a lot longer than you might expect. Here’s how deep humans have dug underground. Below is an incredible animation that shows how deep humans have dug. Hats off to the BusinessInsider team for putting this video together.
