"Structures cosmiques : une famille de géantes"

I was yesterday on France Culture to talk about the discovery of the Quipu Supercluster and other large scale structures.

Structures cosmiques : une famille de géantes

Comment Quipu, structure parmi les plus grandes, a-t-elle été identifiée ? De quoi sont composés les filaments de galaxies et de matière noire qui forment les structures de l'univers ? En quoi leur identification permet-elle de préciser notre compréhension de la cosmologie ?

Get ready to feel cosmically insignificant.
