Not falsifiable, but more parsimonious than thinking that something ‘acts out’ the reality that we see. Other explanations of reality leave behind a material residue. A bit like saying that water is made of wet stuff, fire is made of hot stuff, etc. True explantions ‘destroy’ the things that they explain. And I favor the theological argument that the foundation of reality must be something necessary. Mathematical Platonic reality does the job perfectly.
Well, the bit about platonism may be. Tegmark, I believe, came up with a notion along the lines of “well, if all mathematical structures are in some sense ‘real’, then we just need to somehow parameterize the set of all mathematical structures that could contain beings ‘like us’, then compare our observed universe to the ‘most average’ structures. If we differ significant’y from that, it’s evidence against the proposition.”
