This rules out theories that say gravity should be much stronger over such small scales. In string theory, which is physicists’ best attempt so far to unify the forces of nature, space has six or seven extra dimensions – like the familiar threeexcept that they are curled up, perhaps as ...

The low energy effective Lagrangian of string theory presents us with not only gravity, but the dilaton and the antisymmetric field as well. It is shown that a Brans-Dicke generalization of a metric theory of gravity with torsion that is derived as the exterior derivative of a potential is ...

Edward Witten is an American mathematical physicist who was awarded the Fields Medal in 1990 for his work in superstring theory. He also received the Dirac Medal from the International Centre for Theoretical Physics (1985). Witten was educated at Brandei
String theory is a framework that physicists use to describe how forces usually conceptualized on a gigantic level, like gravity, could affect tiny objects like electrons and protons. InAlbert Einstein's theory of general relativity, gravity is a force that warps space-time around massive objects....
