This article explores the Boltzmann brain hypothesis, the time-asymmetry of memory, and the second law of thermodynamics, formalizing their relationships within a time-symmetric, time-translation invariant Markov process framework. It disentangles these concepts to avoid circular reasoning and offers a novel formal approach to their investigation.
A new paper by SFI Professor David Wolpert introduces a mathematically precise framework for the simulation hypothesis, challenging several long-standing claims and opening up new questions about simulated universes.
Physicists and computer scientists are using stochastic thermodynamics to understand the energy costs of computation, with implications for designing more energy-efficient devices.
