The earliest versions of string theory needed 26 spatial dimensions, but after supersymmetry and some dimensional layoffs, theorists were able to slim that number down to “only” 10.

String theory is the idea that everything in the universe, every particle of light and matter, is comprised of miniscule vibrating strings. These strings are truly tiny, ...

One little problem with string theory: It needs some extra dimensions. Skip to main content. Open menu ... NASA losing nearly 4,000 employees to Trump administration's 'deferred resignation' program.

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

String theory describes nature on extremely small size scales and high energies that are all but inaccessible to modern physics. The ideal experiment would provide direct evidence of these strings ...

Striking evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering that was done by a trio of physicists in the US. By ...

String theorists have used matrices to model the birth of the universe – the moment when three spatial dimensions broke free from the other six and expanded to produce the universe's 3D structure.

String Theory and Number Theory Have More in Common Than You Think, Maaaaaan A physicist and mathematician walk into a weird, mushed elliptical curve. Here's what they find.
