Mariana Trench: The Deepest Place on Earth

The ocean has a valley deeper than Everest is tall, where the water is calm, cold, and totally dark. This episode sinks, gently and safely, all the way down.

The science, gently

  • The trench's deepest point is nearly eleven kilometers down; Everest would vanish beneath the waves there.
  • No storm reaches it: the deep stays still, whatever the surface is doing.
  • Life thrives even there, soft and slow and pale in the dark.

Wonder together

  • What would you say into the deepest quiet on Earth?
  • Why do you think storms cannot reach the bottom?
  • Where is your deepest calm place?

Tonight's calm-down

Sink below your own weather tonight: below the day's waves, below the wind of thoughts, down where it is always still. The deep is not empty. It is just quiet, and it holds.
