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.

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

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 has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

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 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 ...

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

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 ...

Few scientific ideas have been as polarizing as string theory. There are good reasons to both love it and hate it.

Since the 1980s, string theory has emerged as the leading candidate for achieving every physicist’s dream: reconciling general relativity with quantum mechanics and thereby finding a tidy ...

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