Right after the Big Bang, the universe expanded evenly in all directions. And yet, matter began to lump together, later forming galaxies and stars. What is the role of dark matter in all this? Cosmologists have simulated the formation of these structures: Billions of particles expand and start to cluster more and more in the pull of their own gravity. Over the course of billions of years, the interplay between expansion and compaction results in a web-like structure containing the first galaxies.

Concept: Starting point is a scientific computer simulation. The film tells the “story behind”.
