An inhabitant and observer in reality_1 who adopted the hypothesis that his reality was simulated in a reality_0 would be able to draw some conclusions towards a knowledge of that prior reality because even though everything space-like in reality_1 was programmed, there would still exist a relation between the time in the two realities. The cosmology in reality_1 would be notable for its contingent parameters 'lining up' in such a way as to suggest an anthropic principle, that would come out of the programming. Hence anything tainted by dependence on such a principle could be discounted as simulation artefact. Something about time itself would escape this. A purely non-scientific inquiry into time such as we find in Bergson or Heidegger (in different ways) would point the way out of the simulation and into the wider sense of being of reality-0.
