Like the list of the natural numbers. That list is a sort of infinite out of time and space. If Mechanism is assumed, eventually the physical reality emerge from the universal machines experiences/computations, whose existence (and first person views) can be derived from the laws of succession, addition and multiplication. Some people seems to believe that there is a physical universe out there. As a scientist I wait for some evidences for this, but once you understand that all computations are implemented, in the precise mathematical sense of Turing, Church, …, in virtue of the true (sigma_1, with shape ExP(x) and P recursive) arithmetical sentences, it is hard to no doubt about it. The antic dream argument change the burden of the proof. Then it is easy to see that mechanism predicts that if we look below our mechanist substitution level, we must see the sum of all histories, which is arguably what we see thanks to QM. Mechanism solves the problem of the origin of the physical laws, but says nothing about the possible appearance of a physical origin or not. Physics itself might need to solve the problem of unifying gravity and the quantum before making sense of what could happen near or at a “singularity”.
