In this book, Michel Cassé's goal is to render perfectly comprehensible the information provided in Stephen Hawking's sometimes difficult The Universe in a Nutshell. He also aims to restore all the poetry that lies in Hawking's book.
L'Univers envolé offers a blend of poetry and cosmology that opens the gates to mysticism. Cassé's love of the universe, consisting of contemplation, respect and deep communion, resembles that of a medieval troubadour for his lady. This profound feeling of worship for the universe leaves the reader spellbound.
With his unequalled talent, Cassé describes the “most recent arrivals” in the cosmos: the quintessence that fills space and explains the “missing mass”, the supernova explosions that are at the origin of all cosmic creation, black holes which connect everything in the cosmos and which perhaps open out onto other universes.

Michel Cassé is an astrophysicist at the Atomic Energy Commission and an associate research fellow at the Institut d'Astrophysique, in Paris. He is most notably the author of La Petite Etoile, Du Vide et de la Création and Généalogie de la Matière, published by Editions Odile Jacob.
