Wolfson, Ira: Boltzman Brain-Death

The Boltzmann brain hypothesis asserts that thermal fluctuations in a sufficiently old universe will occasionally assemble self-aware observers complete with false memories. We show that the hypothesis is self-defeating at the level of its own premises. Thermal fluctuations require thermodynamics; thermodynamics requires causal interaction between constituents; causal interaction requires information propagability; information propagability requires a non-trivial causal recursion --- that each s
