Tiny Tests Seek the Universe’s Big Mysteries
The search for exotic new physical phenomena is being led by huge experiments like the Large Hadron Collider. But at the other end of the spectrum lie tabletop experiments — small-scale probes of hidden dimensions, dark matter and dark energy.
Physicists Hunt for the Big Bang’s Triangles
The story of the universe’s birth — and evidence for string theory — could be found in triangles and myriad other shapes in the sky.
Michael Atiyah’s Imaginative State of Mind
At 86, Britain’s preeminent mathematical matchmaker is still tackling the big questions and dreaming of a union between the quantum and the gravitational forces.
Taming Superconductors With String Theory
The physicist Subir Sachdev borrows tools from string theory to understand the puzzling behavior of high-temperature superconductors.
String Theory Meets Loop Quantum Gravity
Two leading candidates for a “theory of everything,” long thought to be incompatible, may be two sides of the same coin.
Theories of Everything, Mapped
Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.
The Fuzzball Fix for a Black Hole Paradox
By replacing black holes with fuzzballs — dense, star-like objects from string theory — researchers think they can avoid some knotty paradoxes at the edge of physics.
Science’s Path From Myth to Multiverse
In his latest book, the Nobel Prize winner Steven Weinberg explores how science made the modern world, and where it might take us from here.
