Edward Witten's M-theory conjecture is that there is a theory that has 5 10D superstrings and 11D supergravity as its low energy limit, and is defined nonperturbatively.(adsbygoogle = window.adsbygoogle || []).push({});

Now, I know that Urs and Mitchel are not fans of loop quantization program. fine.

Urs and Mitchell do not think that a loop quantization of 11 dimensional supergravity is physically meaningful.

fine.

But if 11 dimensional supergravity could be nonperturbatively quantized successfully, to the satisfaction of Urs and Mitchel, what are the implications to M-theory and string theory?

but conceptually speaking, if 11 dimensional supergravity were nonpertubative quantized successfully, would the resulting theory be M-theory, or what would be the relation of a nonpertubative quantized 11 dimensional supergravity and M-theory and 5 10D superstring theories?

based on current understanding of string/M-theory,

what would be some qualitative features of a successful nonpertubative quantized 11 dimensional supergravity on the planck scale to the satisfaction of Urs and Mitchell? how does it compare to current pertubative string theory? how does it compare with a loop quantization of 11 dimensional supergravity?

would it consist of wilson loops or spin networks? strings?

Ed Witten hypothesis is that M-theory is the UV completion of 11 dimensional supergravity, does not follow that a successful non-loopy nonpertubative quantized 11 dimensional supergravity is M-theory?

Are there any string theorist like Ed Witten who are attempting to nonpertubative quantized 11 dimensional supergravity? or is there any non-loop research papers and programs that attempt to directly quantize and produce a nonpertubative quantized 11 dimensional supergravity

since string theorists are not fans of loop quantization procedure, have they read loop quantization of 11 dimensional supergravity by loop theorists like Thieman and offer "corrections" to make it more physically correct?
