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 ...

Scientists in Greece have laid out a mathematical framework to help explain a so-far-unsolved gap in our understanding of how ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

For as long as people have looked for answers in the night sky, the idea of stepping into a machine and arriving in an ...

On January 22, 2025, physicists unveiled a groundbreaking discovery that could revolutionize our understanding of the ...

Astronomers from the Flatiron Institute’s Center for Computational Astrophysics (CCA) and colleagues have determined how ...

A new theory-based approach provides access to the minute transverse motion of quarks within protons. Nuclear physicists have developed a new theoretical framework that allows them to calculate a ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for ...

String theory unifies all the forces of nature. Forces that seem very different, such as gravity and electricity, are deeply ...

Quantum theory has been remarkably successful ever since its inception 100 years ago. And yet, there is a glaring mismatch between the discrete, quantum nature of matter and the apparent continuous, ...
