Brightest-Ever Space Explosion Reveals Hints of Dark Matter
A recent gamma-ray burst known as the BOAT — “brightest of all time” — appears to have produced a high-energy particle that shouldn’t exist. For some, dark matter provides the explanation.
A Hint of Dark Matter Sends Physicists Looking to the Skies
After a search of neutron stars finds preliminary evidence for hypothetical dark matter particles called axions, astrophysicists are devising new ways to spot them.
Axions Would Solve Another Major Problem in Physics
In a new paper, physicists argue that hypothetical particles called axions could explain why the universe isn’t empty.
Top Dark Matter Candidate Loses Ground to Tiniest Competitor
Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.
‘Quantum Atmospheres’ May Reveal Secrets of Matter
A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.
Roberto Peccei and Helen Quinn, Driving Around Stanford in a Clunky Jeep
The two physicists who introduced Peccei-Quinn symmetry came up with their idea on and around Stanford University’s campus 40 years ago.
