In the very early, very hot moments of the universe, the electromagnetic and weak nuclear forces were actually the same force—the electroweak interaction. Scientists can now study this interaction ...

The universe is considered metastable, which means there is a chance it could fall apart, or it already has. The ultimate stability of the vacuum of our universe may rest on the masses of two ...

Electroweak burning is the energy released from the conversion of heavier, subatomic particles called quarks (that eventually can turn into protons and neutrons) to lighter, subatomic particles called ...

But despite years of searching, using the most complex machines ever constructed on the planet, the Higgs remained as elusive as a World Series ring for a Chicago Cub. Until now. Physicists at the ...

Scientists announced today (Dec. 13) that they're closing in on the elusive Higgs boson, a subatomic particle that's been predicted but never detected. Now researchers at the world's largest particle ...

Steven Weinberg ’54, the theoretical physicist whose Nobel prize-winning work transformed scientists’ understanding of fundamental forces, died on July 23. He was 88. “[His work] is basically the ...
