The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few ...

Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would seem to exist in three spatial dimensions if it actually ...

Japanese physicists have created a string theory model that simulates the birth of the universe. In their model, the Big Bang was a "symmetry-breaking event" — a fluctuation that caused three spatial ...

Matrix models constitute a powerful nonperturbative framework in which quantum fields and the geometry of space–time are encoded in large matrices. Originally motivated by attempts to formulate string ...

String theory might be the theory of everything… or a flawed framework for theoretical physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

How long’s a piece of string? You may want to sit down for a minute. Gnu2000 String theory entered the public arena in 1988 when a BBC radio series Desperately Seeking Superstrings was broadcast.
