QUANTUM GRAVITY

The world–view shared by most physicists is that the laws of nature are uniquely described by some special action principle that completely determines the vacuum, the spectrum of elementary particles, the forces and the symmetries. Experience with quantum electrodynamics and quantum chromodynamics suggests a world with a small number of parameters and a unique ground state. For the most part, string theorists bought into this paradigm. At first it was hoped that string theory would be unique and explain the various parameters that quantum field theory left unexplained. When this turned out to be false, the belief developed that there were exactly five string theories with names like type–2a and Heterotic. This also turned out to be wrong. Instead, a continuum of theories were discovered that smoothly interpolated between the five and also included a theory called M–Theory. The language changed a little. One no longer spoke of different theories, but rather different solutions of some master theory. The space of these solutions is called The Moduli Space of Supersymmetric Vacua.        SUSSKIND (2003)
