String Theory: A theoretical paradigm in which fundamental particles are realised as vibratory modes of one-dimensional strings, potentially unifying all interparticle forces including gravity.

Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles—though not yet those of our universe.

String theory is at the heart of a debate over the integrity of the scientific method itself.

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests.

And string theory, it turns out, has a persistent problem describing the most popular account of what went on during the universe’s earliest moments after the big bang: inflation.

Many people look at relativity theory—both special and general—and quantum mechanics and think the universe is a strange, strange place. String theory can make both of those theories look as ...
