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 ...

I don't understand string theory. In fact, I bet there's fewer than 1% of the world that can speak cogently on the subject, but I am fascinated by the concept and have read a bit on it. Not enough ...

In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible with our current understanding of 'dark energy'.

Stanford math professor Keith Devlin talks about two new books that call into question the entire idea of string theory. The theory states that tiny vibrating strings make up everything, but some ...

String theory is such a tempting, beautiful idea — but after 60 years, it hasn't produced a final theory or predictions to test against experiment in the real universe. Should we keep hanging ...

String theory remains elusive as a “provable” phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative ...

String theory hopes to be a literal theory of everything — a powerful idea that could completely revolutionize our understanding of the physical world. But it has never been directly tested.

Gauge theory and string theory represent two foundational pillars in contemporary theoretical physics, offering profound insights into the nature of fundamental interactions and the structure of ...

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