The Universe Is Mostly Empty — And Almost Impossible to Imagine

The night sky looks like a flat dome of stars, but that picture is an illusion created by human perception. Every point of light sits at a different depth inside a galaxy hundreds of billions of stars strong, while entire galaxies lie hidden far beyond our local stellar neighborhood.

This documentary follows humanity’s journey from the old celestial sphere to Andromeda, the Local Group, Virgo, Laniakea, the cosmic web and the observable universe — revealing not only how enormous reality is, but how a tiny biological brain learned to map it.
