The Past Hypothesis as Substrate Boot: Why the Universe Began Ordered, and Is Not a Boltzmann Brain

Abstract

The Second Law holds only because the universe began in a low-entropy state that standard cosmology must simply posit. Here the posit is not needed: entropy is carried by recorded error-syndrome bits, and before the error-correcting machinery switches on there are none, so entropy is zero by construction. The same mechanism defuses the Boltzmann-brain objection — such brains can only dominate in eternal equilibrium, which this driven, continuously self-minting substrate (w(a) = −1 + a/28 ≠ −1) never reaches. The reframe is firm; the Boltzmann-brain suppression is new and conditional.
