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

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle ...

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

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 ...

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 ...

The invisible string theory went viral on TikTok in 2023, but has been around for years. Here’s everything to know about the invisible string theory.

Two leading candidates for a “theory of everything,” long thought incompatible, may be two sides of the same coin.

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.
