The Big Bang
How expansion and cooling transformed the early universe from a hot plasma into a transparent cosmos of atoms—and what its oldest light can tell us.

How this film was made
Created and editorially directed by Anders Lunde using a custom production system developed over six months. AI assists research, drafting, programming, and visual production; I review and edit the material and make the final editorial decisions. Narration uses text-to-speech. Visuals combine custom-built scientific animations, AI-generated reconstructions, and credited scientific imagery.
Generated reconstructions illustrate scientific interpretations. They are distinct from photographs, specimens, and measured data.
