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 is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known universe. The ...

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

In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible ...

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 ...

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 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 theoretical physics?" Forty-five years later, ...

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 ...

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.

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 ...
