How far back can we see before the universe hides its own beginning? We journey across 13.8 billion years of cosmic history—from the Moon and Andromeda to Webb’s early galaxies, the cosmic dark ages and the cosmic microwave background.
At the wall of the oldest observable light, the evidence changes. Images give way to elemental abundances, patterns in ancient radiation and models tested against particle physics. Then we reach the question that still has no confirmed answer: did time itself begin?
This film separates direct observations from scientific inference, explains why looking farther means looking further into the past and shows why the cosmic microwave background is not a photograph of the Big Bang.
