Spacetime as an emergent structure from energy, information, and horizon - Conceptual note

Abstract: A conceptual framework is proposed in which spacetime 𝑮𝑶 is not a fundamental structure, but an emergent geometric description within operational domains defined by informational horizons. The framework assumes three primitives — energy 𝑬, information 𝑰, and horizon 𝑶— and specifies, through a minimal set of principles, the conditions under which a geometry 𝐺" can be operationally reconstructed from (𝐸, 𝐼,𝑂). Black holes and cosmological limits are interpreted as horizon transitions 𝑂 → 𝑂#, characterised by changes in accessibility that may be asymmetric, gradual, and irreversible, each potentially giving rise to a distinct geometric description without requiring a global background spacetime. In extreme regimes, 𝐺"may lose operational meaning; the description then remains in pre-geometric terms of (𝐸, 𝐼,𝑂) until a new effective geometry emerges. 𝐺" is thus an operational reconstruction within 𝑂, not a fundamental structure.
