About 60 million years ago, India plowed into Eurasia and pushed up the Himalayas. But when Lucía Pérez-Díaz reconstructed the event in detail, she found that its central mystery depended on a broken geological clock.
Radio waves, longer and less energetic than visible light, give astronomers access to some of the most obscure physics in the cosmos.
Today’s long-anticipated announcement by Fermilab’s Muon g-2 team appears to solidify a tantalizing conflict between nature and theory. But a separate calculation, published at the same time, has clouded the picture.
The new volcanic fissures are more otherworldly than they first appear.
Black holes seemed to come only in sizes small and XXL. A new search strategy has uncovered a black hole of “intermediate” mass, raising hopes of more to come.
The zoo of spontaneously emerging particlelike entities known as quasiparticles has grown quickly and become more and more exotic. Here are a few of the most curious and potentially useful examples.
An unexpected superconductor was beginning to look like a fluke, but a new theory and a second discovery have revealed that emergent quasiparticles may be behind the effect.
Spurred on by quantum experiments that scramble the ordering of causes and their effects, some physicists are figuring out how to abandon causality altogether.
A supernova-like explosion dubbed the Camel appears to be the result of a newborn black hole eating a star from the inside out.
