How Close Are We To.... How close do people on this forum think string theorists are to a full complete non-perturbative description of string theory? Do you think it is a question of months, years or decades before scientists will be able to fully describe the theory? My point on this is that I have just read an article on M. Kaku's website where he states that when a full non-perturbative description of string theory will be made, it will automatically provide evidence for the theory as it can boil down to other simpler theories for which there is already a lot of experimental evidence. Also, I am asking this question because I don't really know the current state of research in string/M-theory and if any progress is really being made. Thanks for any answers!
