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 theorists concede that daily life proceeds just fine in a three-dimensional world. Therefore, the extra dimensions of the string world must be too small to notice: They have to shrink, or ...

These were eventually unified into superstring theory, which also introduces the concept of additional spatial dimensions beyond the familiar three.Simplify the complex world of string and ...

String theorists are betting that extra dimensions do indeed exist; in fact, the equations that describe superstring theory require a universe with no fewer than 10 dimensions.

NOVA: If these extra dimensions exist, does string theory offer any explanation of why there are apparently three space dimensions larger than the rest? Witten: That's a big problem that has to be ...

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 ...

"Most versions of string theory require a total of 10 or 11 spacetime dimensions, with the extra dimensions being sort of 'curled up' or folding in on one another to extremely small scales," Hicks ...

Here’s what you’ll learn when you read this story: String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that ...

String theory was once the hottest thing in physics. In the 1980s and ’90s, it promised seemingly unlimited bounty. Arising from the notion that matter and energy are fundamentally composed of tiny, ...

If the World Science Festival's panel on string theory tackled the question of whether the math behind it could be a reliable guide to reality, its panel on the Limits of Understanding seemed to ...
