A detailed look at the Universe reveals that it's made of matter and not antimatter, that dark matter and dark energy are required, and that we don't know the origin of any of these mysteries. However ...

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 ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

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 ...

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 ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

String theory remains our best candidate for a theory of everything, but where can it be tested? By studying black holes, says Marika Taylor. When you purchase through links on our site, we may earn ...

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 ...
