A relatively brief explanation of Boltzmann Brains
The article discusses the concept of Boltzmann Brains and their relation to quantum mechanics. It suggests that a solution to the associated puzzle may arise from the interpretation of quantum mechanics through Formal Computational Realism. This framework posits that the universe samples every possible quantum observable while adhering to specific rules.
- ▪Boltzmann Brains are a theoretical concept in quantum mechanics.
- ▪The article proposes that Formal Computational Realism could provide insights into the Boltzmann Brain puzzle.
- ▪The framework emphasizes minimal computation while ensuring the marginal distribution of observables aligns with the Born rule.

I think that the solution to the puzzle of Boltzmann Brains will come out of the interpretation of quantum mechanics via the lens of Formal Computational Realism (FCR). On that view, the universe is sampling every possible quantum observable s.t. (i) the marginal distribution of each observable agrees with the Born rule (ii) the overall amount of computation made is minimal. (Tbc this is a very informal description of a rigorous mathematical framework.) For a time moment in an early history of the universe, if the observable you're sampling is related to ...
