Consider for example that there is no such thing as an exact measurement. Although your desk has a finite length, no matter how hard you try, you will not be able to measure it exactly. I have to guess that you are thinking that there is a quantum uncertainty to the exact length of the desk. My understanding is that the length is actually a probability distribution, and I won't ever measure anything below a Plank length. Can a probability function reproduce the inability to create an exact measurement? This is for grins: In physics and cosmology, the mathematical universe hypothesis (MUH), also known as the Ultimate Ensemble, is a speculative " theory of everything" (TOE) proposed by the cosmologist Max Tegmark. en.wikipedia.org IF we are a computer simulation and our consciousness emerges from a mathematical foundation, could there be an objective reality? pbs.org <snip> An un-peer-reviewed 2012 attempt at a more rigorous physical analysis of the situation, “Constraints on the Universe as a Numerical Simulation” by physicists Silas R. Beane, Zohreh Davoudi, and Martin J. Savage, reached the conclusion that “in principle there always remains the possibility for the simulated to discover the simulators.” Their specific prediction was that there might be limitations on cosmic ray energy levels if we live in a simulation. However, the above statement might be overstating their own case: rather than discovering the simulators, if we find that cosmic rays violate these limitations, we will have instead disproved that we’re in a simulation! This paper also predicts why our posthuman descendants might want to simulate our universe: to test out string theory. Currently, string theory is overpowered by a vast landscape of possible versions of string theory, and scientists haven’t figured out which one might describe our universe. Detailed simulations would allow posthuman races to test hypotheses about these universes, ruling out possible versions of string theory to zero in on the one that describes their real universe.
