1 The Peer-to-Peer Hypothesis and a New Theory of Free Will

Nick Bostrom is well-known for arguing on purely probabilistic grounds that we are probably living in a simulation.1 Somewhat similarly, David Chalmers has argued that we should consider the “simulation hypothesis ” not as a skeptical hypothesis that threatens our having knowledge of the external world but as a metaphysical hypothesis regarding what our world is actually made of.2 Finally, the simulation hypothesis is gaining some traction in physics. In "A New Theory of Free Will"3 and "A Unified Explanation of Quantum Phenomena?"4, I argue that a new version of the simulation hypothesis--the Peer-to-Peer (P2P) Simulation Hypothesis--is not only implied by several serious hypotheses in philosophy and physics, but promises to provide a unified explanation of a bunch of baffling physical and metaphysical features of our world. I begin "A New Theory of Free Will " by arguing that we presently have some philosophical and scientific evidence in favor of each of the following hypotheses: 1. Eternalism about physical objects and properties: past, present, and future physical objects and properties exist “timelessly.
