The existence of the universe is purely a matter of chance quantum fluctuations, he says. Just as a particle and its antiparticle can spontaneously arise out of a vacuum, so too can the seed for an entire universe. So quantum theory accounts for why there is something rather than nothing. Nôtre univers est venu par hasard d’une fluctuation quantique du vide. Our universe arose by chance from a quantum fluctuation in the void. And that’s the end of it.
