Physicists propose there may be a new stage for some dying stars. Dubbed electroweak stars, they are fueled by the conversion of quarks to leptons, which prevents or staves off collapse into a black ...

Steven Weinberg, who was acknowledged as one of the world’s foremost theoretical physicists and won the Nobel Prize for showing how to unify two of the principal forces of nature, died July 23 in ...

Scientists want to connect the fundamental forces of nature in one Grand Unified Theory. The 1970s were a heady time in particle physics. New accelerators in the United States and Europe turned up ...

Thirty years ago this month, CERN scientists announced the discovery of the Z boson, an elusive elementary particle that transmits the weak force. On June 1, 1983, physicists at CERN's ...

Physicists in the US claim that there may be “electroweak” stars lurking in the universe. Such stars are, the researchers say, what certain heavy stars could become once they have consumed their ...

The Standard Model is the theory that describes the interaction of forces affecting subparticles, like electrons and quarks. Although this physics deals with the major forces that govern our universe, ...

(via PBS Space Time) Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces. But some extremely subtle clues in ...

Much of the search for dark matter—the invisible substance comprising 80 percent of all the mass in the cosmos—has focused on one type: weakly interacting massive particles (WIMPs). However, there's ...

We think of gravity as weighty—its omnipresent grasp pulling us down to the ground. Try to lift a piano up a flight of stairs and you can feel gravity’s resistance. ( Receive emails about upcoming ...

The Nobel Prize for Physics in 2004 was awarded to David Gross, David Politzer and Frank Wilczek for their discovery in 1973 of ‘asymptotic freedom’, the key ingredient in the underlying theory of the ...
