The five main string-theory candidates may all just be pieces of a larger, cohesive whole — and M-theory could bring them together.

How can the string theory's requirement for extra dimensions possibly be reconciled with our everyday experiences in the universe? Curled up and compact ...

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 ...

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 perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known ...

For decades, physicists have been trying to combine quantum physics and general relativity into a single, unified theory. One of the leading contenders is string theory, an elegant vision in which ...

Bootstrapping strings Evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering. (Courtesy: iStock/Anadmist) Striking ...

Until recently, string theory — long heralded as a 'theory of everything' — hadn't been particularly good at explaining anything. But at a workshop this month at the Kavli Institute for ...

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

And a new approach connects string theory to the dynamics of the quark-gluon plasma observed at particle accelerators. Ultimately, string theory must make contact with data to remain interesting.
