The alarming phenomenon of particle creation in the expanding universe

Rocky KOLB

Fermilab, Chicago, USA

Résumé : The expansion of the universe can convert virtual particles in the quantum foam of vacuum quantum fluctuations into real particles. Although Schroedinger studied this phenomenon in 1939, only recently have we been able to observe the effects of particle creation in the expanding universe. Perhaps the universe displays the pattern of early-universe vacuum quantum fluctuations.
