# It from Bit **Domain:** Physics / Information Ontology **Doc Type:** Concept Node **Maturity:** Evolving **Related:** [[John Archibald Wheeler]], [[Information, Physics, Quantum]], [[Quantum Foundations]], [[Holographic Principle]] --- ## Definition **It from Bit** is John Archibald Wheeler's formulation that physical reality is rooted in binary, observer-participatory acts of distinction and answer. ## Corpus Context The idea is central to [[articles/Beyond the Sea|Beyond the Sea]] because it destabilizes simple matter-first assumptions. It is not proof that reality is software; it is a research-guiding claim that information and observation belong inside the account of physical existence. ## Key Insight **This node connects its historical or conceptual subject to the corpus without treating analogy as proof of direct influence.** ## See Also [[John Archibald Wheeler]], [[Information, Physics, Quantum]], [[Quantum Foundations]], [[Holographic Principle]] ## Sources / Provenance - [[articles/Beyond the Sea|Beyond the Sea]]
