Contents On the Nature of Time

This text explores the nature of time from a computational perspective. It argues that time is not a fundamental coordinate but rather a consequence of the universe's computational processes. The author proposes that time is "the progressive doing of computation by the universe," and that our perception of time arises from our own computational limitations as observers. The text further suggests that the universe's computational irreducibility, the idea that there is no shortcut to understanding a system's evolution, contributes to the robustness of time as a unidirectional flow. The author also examines the concepts of multiple threads of time, the ruliad (the totality of all possible computational processes), and the role of computational boundedness in shaping our perception of time and physical laws.
