Why Can't Our Brain Grasp The Depth Of These Deep Sea Trenches?

Drop a weight over the deepest place on Earth and it falls for four hours, and when it lands it settles onto mud older than farming, in a darkness where sunlight has never once arrived. This is the story of why the human mind physically cannot hold the scale of the ocean's deepest trenches, told through twelve impossible facts, from a hidden sound channel that carries a whale's voice across an entire ocean to the two men who fell for nearly five hours to spend just twenty minutes at the bottom of the world. It is a descent into the one place on our own planet we have mapped less thoroughly than the surface of Mars.
