Physicists Uncover Geometric ‘Theory Space’
A decades-old method called the “bootstrap” is enabling new discoveries about the geometry underlying all quantum theories.
What Sonic Black Holes Say About Real Ones
Can a fluid analogue of a black hole point physicists toward the theory of quantum gravity, or is it a red herring?
Responding Rapidly to Big Discoveries
How do scientists react to major breaking science news? For astrophysicists after the big gravitational waves announcement, it was meeting for two weeks in Santa Barbara, California.
Colliding Black Holes Tell New Story of Stars
Just months after their discovery, gravitational waves coming from the mergers of black holes are shaking up astrophysics.
LIGO Reports Second Black-Hole Merger
The spokesperson for the Laser Interferometer Gravitational-Wave Observatory called it “a promising start to mapping the populations of black holes in our universe.”
Janna Levin’s Theory of Doing Everything
The astrophysicist, conceptual writer and host of standing-room-only scientific soirees at a repurposed factory in Brooklyn sees science as a powerful force in culture.
After Black Holes Collide, a Puzzling Flash
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?
From Einstein’s Theory to Gravity’s Chirp
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.
Gravitational Waves Discovered at Long Last
Ripples in space-time have been detected a century after Einstein predicted them, launching a new era in astronomy.
