[00:00:00]Human eyes are extraordinary, sensitive enough to detect a candle flame from 48 km away on a clear night. Now you are at the void center, pupils fully open, retinas waiting. Almost nothing arrives.

[00:00:12]The nearest galaxies are 150 [music] million light-years away. Their light obeys the inverse square law. Every time distance doubles, [music] brightness drops four times. Across this distance, that light becomes a ghost. Your brain receives near zero input and refuses to accept it. Your visual cortex starts generating its own signal. [music] First comes Eigengrau, a dark gray, not true black, produced by your retinal cells firing randomly with no real stimulus. Then shapes, soft moving patches of light, faint geometry drifting across your vision. Your brain, starved [music] of the real world, quietly begins building a fictional one for you.
