Math Proof Draws New Boundaries Around Black Hole Formation
...density approaches infinity and known physics goes off the rails. In the 100-plus years since, physicists and mathematicians have explored the properties of these enigmatic objects from the perspective of...
Cosmic Triangles Open a Window to the Origin of Time
...the final answer without ever working through the complicated particle dynamics. The results hinted that the usual picture of particle physics, in which particles move and interact in space and...
Why an Old Theory of Everything Is Gaining New Life
...description — the Standard Model of particle physics — constitutes physicists’ best current explanation for everything. It’s neat and it’s simple, but no one is entirely happy with it. What...
How the Neutrino’s Tiny Mass Could Help Solve Big Mysteries
The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and reshape theories of cosmology. Of all the known...
A Child’s Puzzle Has Helped Unlock the Secrets of Magnetism
People have known about magnets since ancient times, but the physics of ferromagnetism remains a mystery. Now a familiar puzzle is getting physicists closer to the answer. For a few...
Roberto Peccei and Helen Quinn, Driving Around Stanford in a Clunky Jeep
...or out — in clearing a path to inspiration. Four decades ago, Helen Quinn and Roberto Peccei took on one of the great problems in theoretical particle physics: the strong...
Dark Energy May Be Incompatible With String Theory
...awoke in Vienna and groggily scrolled through an online repository of newly posted physics papers. One title startled him into full consciousness. The paper, by the prominent string theorist Cumrun...
Joe Polchinski’s Restless Pursuit of Quantum Gravity
...or out — in clearing a path to inspiration. As a young professor at Harvard University in 1997, Juan Maldacena reshaped fundamental physics with the discovery that, as he put...
Graphene Superconductors May Be Less Exotic Than Physicists Hoped
...of 20th-century physics who tried and failed to understand why many metals carry current without resistance at low temperatures. In 1957, nearly half a century after this standard kind of...
