Lurking in the 11 th dimension was an entirely new theory which could reduce down to 11 dimensional supergravity as well as 10 dimensional string theory and p-brane theory. |
The advantage of the extra dimensions is that they allow supergravity theories to incorporate the electromagnetic, weak, and strong forces as well as gravity. |
Hyperspace theory is also referred to as Kaluza-Klein theory and supergravity. |
Theories involving supersymmetry in its local form are therefore often known as supergravity theories. |
If global supersymmetry doesn't work, then what about local supersymmetry, i.e. supergravity? |
His groundbreaking work in the areas of superstring theory, supersymmetry and supergravity has made him a leading expert on the topic. |
