Richard Feynman’s famous diagrams weren’t just a way to do calculations. They represented a deep shift in thinking about how the universe is put together.
The spokesperson for the Laser Interferometer Gravitational-Wave Observatory called it “a promising start to mapping the populations of black holes in our universe.”
A satellite spotted a burst of light just as gravitational waves rolled in from the collision of two black holes. Was the flash a cosmic coincidence, or do astrophysicists need to rethink what black holes can do?
The path from a revolutionary set of equations to the detection of gravitational waves was strewn with obstacles and controversy, explains the physicist Daniel Kennefick — and the struggle continues.
Ripples in space-time have been detected a century after Einstein predicted them, launching a new era in astronomy.
Bizarre quantum bonds connect distinct moments in time, suggesting that quantum links — not space-time — constitute the fundamental structure of the universe.
Two leading candidates for a “theory of everything,” long thought to be incompatible, may be two sides of the same coin.
Nima Arkani-Hamed is championing a campaign to build the world’s largest particle collider, even as he pursues a new vision of the laws of nature.
Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.
