If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

For most of the 20th century, the center of gravity in science was anywhere but the US. On the eve of World War II, the great ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

But Crayon Physics Deluxe takes back the idea of play, reasserting a focus on creativity as opposed to gleeful destruction.

“We showed that if black hole morsels are created during mergers, they would produce a burst of high-energy gamma rays, with the delay time related to their mass,” Dr. Cacciapaglia said. “Our analysis ...

Is gravity the real, overlooked reason we age? Deepinder Goyal has dropped a series of tweets, claiming that gravity could be the real reason we age.
