From Psi Gravity to Dimensional Sufficiency

The dark matter problem is often presented as a question of absence:something unseen, undetected, yet gravitationally active.This work explores a different possibility — that the anomaly may arise not from missing matter, but from how gravity itself is described across scales. Rather than proposing new particles or modifying local gravitational laws, the article develops a unifying conceptual framework linking three complementary perspectives:psi-gravity as a coherent gravitational wave function, collective gravitational organization emerging from visible matter, and dimensional sufficiency as an effective geometric response at large scales. Within this picture, dark matter phenomenology appears as a classical projection of quantum coherence.Galactic rotation curves, diffuse halos, and the baryonic Tully–Fisher relation emerge naturally from the interplay between gravitational coherence and geometry, while the well-tested local predictions of general relativity remain intact. The work is intentionally falsifiable.It outlines observational distinctions between geometric–coherent halos and particle-based scenarios, highlighting potential signatures in gravitational lensing, baryonic correlations, and gravitational-wave propagation. No claim of finality is made; instead, the framework is offered as an alternative route for understanding long-standing anomalies. Written as a synthesis rather than a manifesto, the article aims to widen the conceptual space in which gravity and cosmology are discussed.It is addressed to readers who may feel that the dark matter problem deserves not only new entities, but also new language — one that bridges quantum structure, emergent geometry, and human understanding.
