Provide a detailed theoretical analysis of the Simulation Argument proposed by Nick Bostrom. Break down the trilemma into its three components: 1) The fraction of human-level civilizations that reach a post-human stage, 2) The fraction of post-human civilizations interested in simulating their ancestors, and 3) The fraction of all observers that live in a simulation. Discuss the logical implications if any of these fractions are near zero or near one. Conclude with a discussion on the falsifiability of this hypothesis and its impact on our understanding of physical reality.
