We don’t know very much about our universe. We’re fairly certain it exists, but we don’t know how it got here, how long it’s been here, or how big it is. Heck, we don’t even know if our universe is ...

In theoretical physics, superstring theory is presently the most lively effort to formulate a quantum theory of gravity and to provide a unified field theory that explains the fundamental forces of ...

Superstring theory is not entirely beyond the reach of observation. It predicts a large negative cosmological constant and astronomers are pretty certain that the value is small positive. That's one ...

Superstring theory is an attempt to explain all of the particles and fundamental forces of nature in one theory by modelling them as vibrations of tiny supersymmetric strings. 'Superstring theory' is ...
