Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...

Michael Dine, a professor of physics at UC Santa Cruz, will take part in the World Science Festival now under way in New York City, joining a panel discussion on string theory on Thursday, May 30, on ...

In March 2025, the Dark Energy Spectroscopic Instrument (DESI) released its most detailed map of the universe yet, plotting the positions of 15 million galaxies. With the results, the DESI ...

At a 1990 conference on cosmology, I asked attendees, who included folks like Stephen Hawking, Michael Turner, James Peebles, Alan Guth and Andrei Linde, to nominate the smartest living physicist.

Heterotic string theory remains a captivating framework in the pursuit of unifying quantum mechanics with gravity. By merging aspects of bosonic and supersymmetric strings, it provides a fertile ...
