Ever wondered if planet Earth makes a sound? We know it’s a strange question. As citizens of the Earth ourselves, we know that the planet produces a wide range of different sounds. But the question goes a little bit deeper, both literally and figuratively. What does the Earth sound like down there, at its lowest-possible reachable point?

Science tells us that the Earth’s inner core is primarily a 760-mile solid ball filled with iron-nickel alloy and with temperatures as high as that of the surface of the Sun! But that still doesn’t answer our question. Yes, we know it’s hot down there, but what does it really sound like?

There’s a Hole In Our Story

There’s an old conundrum involving holes in philosophy: Do holes exist or are they simply an absence of existence? A fascinating metaphorical problem, but one that doesn’t really suit today’s story. After all, listening to the sound of the Earth wouldn’t be possible if it wasn’t for some of the world’s biggest holes.

But how deep do these holes go, and what are they used for? Most of the world’s artificially-produced super holes have a scientific purpose. They’re vital for studying geophysics and helping us learn more about essential things such as seismic and thermic regimes in the Earth’s crust. But can they be used for… art?
