Information-theoretic reconstructions of quantum theory and black-hole thermodynamics hint at a deep role for information, but "it from bit" remains a research program, not a result.
Bekenstein argued black holes carry entropy proportional to their horizon area, tying gravity, thermodynamics, and information together.
Hawking showed black holes radiate thermally, confirming they are thermodynamic objects with a temperature and entropy and raising the information-loss puzzle.
Maldacena's duality equates a gravitational theory in a volume with a non-gravitational quantum theory on its boundary, a concrete realization of the holographi…
Wheeler proposes that every physical entity derives its existence from binary, information-theoretic answers to yes/no questions — information as the ground of…
