Our observable universe evolved from an extraordinarily hot, dense early state. What came before, and how to describe the first instant, remain open questions.

EX NIHILO compresses those first 13.8 billion years into a single scroll. Here, the scrollbar is time: drag it forward and you pull the universe into being — the Big Bang, the first light, the first stars, the slow turning of galaxies, and their long fall toward one another.

It is rendered live — light, sound, and mathematics, computed in the moment, never a video. The sound you hear is generated as you go; the clock in the corner follows an illustrative cosmic timeline.
