1- witten said that M-theory consists of 11 dimensional Supergravity, [itex]GR+SUSY,[/itex] as a low energy limit, and 5 10dimenstinoal string theories related by dualaties. since the "Askhar new variables" could be applied to 11 dimensional super gravity, creating spin networks that carry more quantum numbers, the result of which is background independent, what would be some of the implications with respect to loop quantum gravity and string theory, if this program is successful, and produces or solves problems? specifically, we know that LQG is background independent, but does not yet admit of GR as a low-energy limit. M-theory, currently, is background dependent, but the gravitons interact in such a way that reproduces many of hte features of GR. it is not clear the "space" described by LQG spin networks gives us 4-D space govern by GR. but perhaps the background independent SUSY-11D spinnet works, with superstring gravitons flying around, gives us the features of GR and background independence. how would superstring's spin-2 gravitons interact in a 11-dimensional, SUSY spinnetwork "weave" state derived from askhtar's new variables of an 11-dimensional SUSY GR? |
