Celia Escamilla-Rivera is combining large data sets with supercomputers to test general relativity against its little-known competitors.
Cosmologists Parry Attacks on the Vaunted Cosmological Principle
A central pillar of cosmology — the universe is the same everywhere and in all directions — is surviving a storm of possible evidence against it.
The Cosmologist Who Dreams in the Universe’s Dark Threads
Cora Dvorkin discovered new possibilities for what dark matter could be. Now she’s devising unorthodox ways to identify it.
The Physicist Who Slayed Gravity’s Ghosts
Claudia de Rham showed how theories of “massive gravity” could potentially get rid of the need for dark energy.
