On Certain Questions of the Theory of Gases

In a long-lived, accelerating universe, random thermal fluctuations could spontaneously assemble a self-aware brain with false memories of a coherent life. Several modern cosmological models appear to predict such observers should statistically dominate — which is widely treated as a reason those models are wrong, not as evidence about you.

Physics-adjacent worldviews — block universe, many-worlds, simulation, free will.

Many-worlds, simulation, mathematical universe.

Cryptomnesia, anoxia models, cold reading. Counter-anchors.

The default scholarly reference for what Many-Worlds actually claims and where it is contested.

Useful conceptual reference for any claim about long-term cosmology and the cosmological-horizon temperature.

The most accessible book-length introduction to why physicists worry about the Boltzmann-brain problem and how it interacts with the arrow of time.

The standard reference for the cognitive-instability resolution and the philosophical case against taking Boltzmann-brain dominance as a real prediction.

Major physical objection to Boltzmann-brain dominance: the static de Sitter vacuum is sterile, so the mathematical fluctuation probability does not translate into real observers.

The clearest statement of how the Boltzmann-brain count is tamed by a finite vacuum lifetime; companion paper to 'Return of the Boltzmann brains'.
