A First Step Toward a Foundational Picture of the Nature of Gravity: Conceptual Framework and Testing Programme

This paper expands upon the core principles and foundational arguments of the Planck Gravity framework, which were previously established and published via Zenodo under DOI: https://doi.org/10.5281/zenodo.22995823 ABSTRACT:This paper proposes an initial conceptual framework within Planck Gravity (PG) for investigating whether macroscopic gravity could be an effective manifestation of a microscopic structure of spacetime. PG hypothesizes a discrete grid of directed Gravitational Planck cells (GP cells). Component X is introduced as a hypothetical microscopic constituent that may interact locally with this grid. The collective response of the grid is proposed as a possible route toward explaining observable gravitational quantities. Current knowledge of gluons, quantum chromodynamics (QCD), and quark–gluon plasma provides the physical context, but established physics is distinguished from PG-specific hypotheses. The present investigation provisionally stops at the gluon level, where modern physics has developed a substantial theoretical and experimental framework. This is a scope choice, not a claim that gluons are nature’s ultimate constituents; deeper degrees of freedom remain a legitimate research question. Component X has not been independently established as a known particle or field. For black holes, the paper uses the exterior Schwarzschild geometry as a reference anchor. Defining S(r) = σ(r)² = 1 − r_s/r and l_app(r) = l_pσ(r), with r_s = 2GM/c², gives S(r_s) = 0 and l_app(r_s) = 0 by definition. These are conditional results and do not independently establish PG microphysics. The manuscript identifies a mathematical inconsistency that must be resolved: one cannot simultaneously retain S(r) = 1 − r_s/r exactly up to the horizon and require dS/dr to approach zero there. The proposed cell-locking variable qΩ is therefore retained as a modelling direction, not presented as a fully consistent solved equation. This paper is an initial conceptual framework and testing programme; it does not claim that PG has been experimentally confirmed.
