Alongside string theory’s explanation of the generation of subatomic particles is another idea often found in science-fiction novels: the concept of extra dimensions.

The answer, dear multi-dimensional bundles of vibrating string, lie as much in our selves as in our stars. It’s not just that the math of string theory is complex, though it certainly is.

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, ...

String theory and number theory have common ground in a specific kind of elliptic curve from a torus. Toruses aren't just for compressing atoms: these curves represent torus cross-sections.

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be ...

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 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 ...

Still others suspect that dark energy is a sign that our currently accepted theory of gravity—Einstein’s general theory of relativity—is incomplete for the largest distances.

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 ...
