What's up in
Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.
In the hunt for new fundamental particles, physicists have always had to make assumptions about how the particles will behave. New machine learning algorithms don’t.
New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.”
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.
Updated results from a Japanese neutrino experiment continue to reveal an inconsistency in the way that matter and antimatter behave.
The universe has not cooperated with physicists’ hopes. In desperation, many are looking for new ways to search for surprises at the Large Hadron Collider.
