Well, SUSY (supersymmetric spacetime) is how I intuitively understand the concept of spacetime, so I find a lot of reasons to logically agree with it. Considering grand unification theory, if the universe were to be of such high energy consistency early on, then it would follow that it was symmetric, and spontaneous SUSY breaking in turn causes baryogenesis. It just seems logical to me. The only issue is proving it would require LHC upping it's energy by a lot, and it's past effort to find SUSY didn't work out.
