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 ...

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 ...

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

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 ...

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.

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 ...

A University of Colorado Boulder physicist is one step closer to solving a string theory puzzle 20 years in the making. Paul Romatschke, an associate professor of physics at CU Boulder, has devised an ...

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 ...

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 ...

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