String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

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 is a mathematical description of nature that requires space to possess several additional dimensions beyond the ordinary three. These extra dimensions, too small to notice in ...

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

A groundbreaking discovery in the realm of physics has scientists abuzz with the potential confirmation of a portal to other ...

String theory proposes that the universe’s fundamental particles aren’t points but tiny vibrating strings, whose different modes create the variety of matter and forces, including gravity ...

Improvements to perturbation theory and approximation schemes provide some hope for making a breakthrough to link the dimensional structure of the extra dimensions to predictable physics.

String-theory p-branes are good candidates for brane worlds because they possess gauge symmetries on their “surfaces” and automatically incorporate a quantum theory of gravity, namely string theory.

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what’s all this nonsense of extra dimensions? PBS Space Time is available to stream on pbs.org and ...

A year ago, the top living string theorist, Ed Witten, wrote a piece on what every physicist should know about string theory. Here's what that means, translated for non-physicists.
