Boltzmann Brain Problem
A thought experiment/paradox arising from certain cosmological models, in which random thermodynamic fluctuations should statistically produce far more isolated self-aware “brains” than entire ordered universes — used as a stress-test against theories.
Proponents
Ludwig Boltzmann (origin of concept), Andreas Albrecht & Lorenzo Sorbo (modern cosmological framing)
Evidence For
A rigorous consequence of applying statistical mechanics to eternal/infinite universe models.
Evidence Against
Widely treated as a reductio ad absurdum signaling a flaw in the model producing it, rather than a claim about reality itself.
