CORRECTION: As some of you have pointed out, at 2:12 the narration should say "diamond-mesh coated rebar" not "diamond-coated rebar." It sounds awesome, but it doesn't make sense to reinforce the walls of a gold mine with minerals more expensive (and brittle) than gold.
Krubera Cave, one of our planet’s deepest known caves, extends 2200 meters into the earth – that’s a depth of nearly six Empire State Buildings. Or at least, that's as far down as humans have been able to explore; there might be other undiscovered chambers that go down even farther. But the cave can't be that much deeper, because there's a limit – actually, three limits – to how deep caves on Earth can get.
