Visualization of the allowed values of "dial settings" in the scattering amplitudes that describe the probability for particles to interact in the models introduced in this new work. The regions in ...

Modern multiverse fiction incorporates real physics equations and string theory principles rather than relying on pure ...

Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory.

Three decades ago, a British documentary series named Connections aired, which showed viewers how various scientific achievements and discoveries were really interrelated, no matter how disparate they ...

String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...

After the star-studded mystery thriller The Number 23 debuted in cinemas in 2007, many people became convinced that they were seeing the eponymous number everywhere. I was in school at that time, and ...

Mathematicians are exploring a string duality between F-theory and heterotic string theory in eight dimensions. Simply put, string theory is a proposed method of explaining everything. Actually, there ...

For the last 40 years, a dedicated group of theoretical physicists has been beavering away on an ambitious project to create a quantum theory of gravity and unify the four forces of nature. Using ...

In October 1984 I arrived at Oxford University, trailing a large steamer trunk containing a couple of changes of clothing and about five dozen textbooks. I had a freshly minted bachelor’s degree in ...

An illustration of two black holes about to merge and emitting copious gravitational waves. And as the numbers of gravitational-wave observations have increased, physicists’ careful modeling is ...
