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 ...

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 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 ...

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.

But there is more to string theory than just explaining gravity on a molecular level; string theory is, essentially, the theory of everything. It is the attempt to unite the physics of our universe.

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 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 ...

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

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 ...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a "provable" phenomenon. But a team of physicists has now taken a ...

Einstein desperately wanted a unified theory of physics. Thanks to gravitational waves—the poster child of general relativity—his wish might just come true. Gravitational waves are ripples in ...

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