Just two questions that come to mind when thinking about the string landscape proposed by Susskind and others: 1. When talking about the string landscape, do people refer to the supersymmetric string vacua or the non-supersymmetric string vacua? Is it only the supersymmetric string vacua whose number is estimated to be 10^100? 2. Are all the string vacua different solutions to one theory (M-theory for example) or do they all represent different theories just related by dualities and no underlying grand theory? Thanks to anyone who is willing to answer any of these points.
