Video Description

In this episode of Cosmology 101, we unravel the cosmic web, a vast, intricate network of galaxies and dark matter that stretches across the universe. Discover how the seemingly random distribution of galaxies forms a web-like structure influenced by the primordial plasma, gravity, and dark matter from the early universe. Join Katie Mack, Perimeter Institute’s Hawking Chair in Cosmology and Science Communication, on an incredible journey through the cosmos in our new series, Cosmology 101.
