Deep Space for Sleep | The Largest Structure in the Universe

Trace the shape of everything — from the galaxy clusters that anchor our cosmic neighborhood, to the vast invisible threads of the cosmic web, to walls of galaxies stretching billions of light years across the sky, to the great cold emptiness of voids so large they would have hidden the universe from us entirely. This episode travels to the outermost edges of the observable universe to map its largest known structures. Perfect for sleepyheads, insomniacs, deep thinkers, and anyone who has ever looked up at the night sky and felt the particular, quiet comfort of feeling genuinely, peacefully small.
