Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already enabled the researchers to solve a longstanding problem in the materials science and physics worlds known as the polaron problem, giving scientists and engineers a way to predict how …

Sign up for the Starts With a Bang newsletter Travel the universe with Dr. Ethan Siegel as he answers the biggest questions of all. Since the 1800s, energetic particles have probed the fundamental nature of matter. Rutherford’s gold foil experiment showed that the atom was mostly empty space, but that there was a concentration of mass at one point that …

A novel approach to the search for a long theorized fifth force of nature—one that could potentially help scientists unravel lingering mysteries involving the Standard Model of particle physics—is being undertaken by physicists in Switzerland. Among these mysteries, the quest to resolve the elusive nature of dark matter, as well as the ongoing search for new particles and other discoveries …
