Could the universe have more dimensions than we realize? (Image credit: Getty) String theory is a purported theory of everything that physicists hope will one day explain … everything.

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 ...

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the ...

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 ...

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

For another, string theory, even in "only" 10 dimensions, doesn't give you General Relativity as your theory of gravity, but rather a 10-dimensional Brans-Dicke theory of gravity.

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial ...

Mathematicians are exploring a string duality between F-theory and heterotic string theory in eight dimensions.

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