*I used "perceived" to indicate no bias for or against a material universe. We are always dealing with observations, so if the MUH were correct, it would mean we could observe plane waves (or for that matter, advanced waves). But the former can never be observed in any universe unless you want to posit instantaneous propagation initially, at their creation, and on-going as the amplitude changes immediately in all directions to infinity as the wave propagates. As for advanced waves, they have never been observed and their existence likely trashes causality. So IMO, the MUH is easily falsified.
