- David Wolpert co‑authored the May 3 2026 paper that reframes the Boltzmann‑brain paradox as a flaw in the H‑theorem’s time‑symmetry.
- Carlo Rovelli contributed a formal framework linking the “past hypothesis” to low‑entropy Big‑Bang conditions, showing how assumptions about the universe’s start affect memory reliability.
- Jordan Scharnhorst introduced the “entropy conjecture,” exposing circular reasoning where assumed past states are used to justify the second law.
- Santa Fe Institute hosted the interdisciplinary team, emphasizing a statistical‑physics review of cosmological inference.
- Entropy conjecture (as defined by the authors) claims that entropy‑based arguments for memory reliability are self‑referential, prompting a reevaluation of cosmological models.
