Early Tuesday morning, three physicists—James Peebles, Michel Mayor and Didier Queloz—were rewarded for decades seminal contributions to advancing science with a phone call from Stockholm. This year’s Nobel Prize in Physics was awarded “for contributions to our understanding of the evolution of the universe and Earth’s place in the cosmos.”

Our world is governed by general relativity, which sees gravity as the effects of massive objects warping space-time. The world of particle physics, on the other hand, envisions all forces as mediated by force-carrying particles — and ignores gravity entirely. This year’s Breakthrough Prize in Fundamental Physics was awarded to three theorists who proposed a way to marry these contradictory descriptions: with a theory called “supergravity.”
