According to some physicists (for instance John Baez
and Peter Woit), both string theory and loop quantum
gravity have not made much progress recently.
How active are other approaches like noncommutative
geometry, euclidean quantum gravity, discrete
approaches (Lorentzian, Regge calculus, ...), twistor
theory, topos theory, supergravity, Ads/CFT, emerging
properties (Robert Laughlin)...?
