vendingmachine commented on the word quantum foam
"Armed with theoretical microscopes, quantum physicists keep on magnifying, gazing deeper and deeper into empty space until out of nothing, they suddenly see something. That something is a roiling collection of virtual particles, collectively called quantum foam.... According to quantum physicists, virtual particles exist briefly as fleeting fluctuations in the fabric of spacetime, like bubbles in beer foam."
