At the heart of the experiment is one of the weirdest, and most important, tenets of quantum mechanics: the principle that empty space is anything but. Quantum theory predicts that a vacuum is actually a writhing foam of particles flitting in and out of existence.

Although equal quantities of matter and antimatter are thought to have been created in the Big Bang, we see almost no antimatter in today’s Universe. This asymmetry not only implies a cosmic favouritism for matter, but also suggests that physics does not always work the same way when time is run backwards instead of forwards.
