A Conceptual Framework for Informational Monism: Toward a Unified Substrate for Consciousness and Cosmology

This paper develops an exploratory framework based on informational monism: the view that a single underlying substrate—here termed the Information Field (Ψ_I)—gives rise to both physical reality and conscious experience. The framework does not propose a physical theory, nor does it attempt to replace existing models. Instead, it highlights structural parallels between two long-standing scientific gaps: the Hard Problem of Consciousness and the Cosmological Inventory Problem, particularly the unexplained 95%/5% division between the dark sector and baryonic matter. I propose that these two problems may share a common origin if both physical structure and subjective experience are treated as distinct expressions of a single informational substrate. This perspective motivates a search for a deeper law—an underlying Lagrangian L_{Ψ_I}—that could formally describe how differentiation of this substrate yields the observed cosmic composition and the emergence of integrated experience.
