If that is the MUH, then that it is plainly ridiculous, indeed. To have a perceived universe, you need a measure on the computation/sigma-sentences. The physical emerges from an arithmetical phenomenon (assuming mechanism in cognitive science). The version of mathematicalism implied by mechanism does not lead any choice for the “physical reality”, it has to be a statistic on computations structured by the “observable” mode of self-reference. That indeed predicts quantum logic, and the many “histories” interpretation of arithmetic. Oracle are not impossible, but there are no evidence for them, and should be invoked in last resort (a bit like the “Alien” in cosmology). The empirical evidence is that there is no physical universe at all.
