Add Yahoo as a preferred source to see more of our stories on Google. Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit ...

String theory seeks to describe fundamental interactions by modelling particles as one-dimensional strings. In efforts to unify quantum mechanics and general relativity, it introduces additional ...

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?” Hawking, who later became my ...

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 ...
