Quantum field theory may be the most successful scientific theory of all time, but there’s reason to think it’s missing something. Steven Strogatz speaks with theoretical physicist David Tong about this enigmatic theory.
Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the universe, and other mysteries.
Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them.
Three physicists stumbled across an unexpected relationship between some of the most ubiquitous objects in math.
The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and shape theories of cosmology.
High-energy neutrinos have been traced back to a flaring supermassive black hole known as a blazar. The long-sought link opens the door to an entirely new way to study the universe.
An experiment at the Fermi National Accelerator Laboratory near Chicago has detected far more electron neutrinos than predicted — a possible harbinger of a revolutionary new elementary particle called the sterile neutrino, though many physicists remain skeptical.
