🔄FROM THE ARCHIVE: While the novel theory may never live up to the early hype, its innovative tools have helped scientists for decades, and the best may be yet to come.

Arising from the notion that matter and energy are fundamentally composed of tiny, vibrating strings rather than pointlike particles, this theory attempted to unify all the known forces into a single, elegant package. Some physicists hailed string theory as the long-sought “theory of everything.
The gamble paid off. In 1985, three years after getting his Ph.D., Strominger co-authored one of the field’s seminal papers — part of the so-called “first string revolution.” Scientists quickly learned that this newfound symmetry could be harnessed to address various mathematical puzzles. In 1991, the physicist Philip Candelas and his colleagues used mirror symmetry to solve a century-old problem, in effect counting the number of spheres that could fit inside a Calabi-Yau space.
“During the past few years, progress has been made toward encapsulating this idea within one formula,” says Brandeis University mathematician Bong Lian. “The geometric, algebraic and physical pictures of mirror symmetry are all starting to converge.”While Strominger co-authored a 1996 paper that offered a mathematical explanation for how mirror symmetry works, his emphasis over the past two decades has been on using string theory to gain insights into black holes.
Strominger has continued to press further. His work with Vafa showed that rapidly rotating black holes have “conformal symmetry,” which roughly means that certain physical properties are independent of the black hole’s size. Strominger subsequently realized that the presence of this symmetry, which hadn’t been recognized before, could be used to support a range of predictions.
