String theory, a mathematical construct aiming to unify physics, posits the existence of extra, curled-up dimensions. Public and media interest in string theory has waned in recent years, coinciding ...

Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...

There are plenty of reasons not to like string theory. Philosophical and logical arguments against the theory have long been apparent. Strong scientific evidence is increasingly joining them. The ...

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, ...

Researchers at The University of South Carolina, USC, have proposed that a link between string field theory and quantum mechanics does exist. The link assumes that string field theory is a fully ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

Stanford math professor Keith Devlin talks about two new books that call into question the entire idea of string theory. The theory states that tiny vibrating strings make up everything, but some ...
