# John Archibald Wheeler **Domain:** Physics / Information / Cosmology **Doc Type:** Thinker Node **Maturity:** Evolving **Related:** [[It from Bit]], [[Quantum Foundations]], [[Information Theory]], [[Measurement Problem]] --- ## Definition John Archibald Wheeler (1911–2008) was an American theoretical physicist associated with nuclear physics, gravitation, black holes and the informational interpretation summarized by the phrase “it from bit.” ## Corpus Context [[articles/Beyond the Sea|Beyond the Sea]] uses Wheeler as a credentialed entry into the proposition that information may be constitutive rather than merely descriptive. The corpus preserves the boundary between Wheeler's participatory physics and stronger claims about simulated worlds or uploaded minds. ## Key Insight **This node connects its historical or conceptual subject to the corpus without treating analogy as proof of direct influence.** ## See Also [[It from Bit]], [[Quantum Foundations]], [[Information Theory]], [[Measurement Problem]] ## Sources / Provenance - [[articles/Beyond the Sea|Beyond the Sea]]
