  skos:definition "Quantum foam or spacetime foam is a theoretical quantum fluctuation of spacetime on very small scales due to quantum mechanics. Matter and antimatter are constantly created and destroyed. These subatomic objects are called virtual particles. The idea was devised by John Wheeler in 1955.

La mousse dont il est question est une manière de conceptualiser la nature de la structure infime du \"matériau\" dont l'univers est constitué.
