Dark Matter as Non-Equilibrium Virial Geometry

The dark-matter problem is usually interpreted as evidence for unseen mass. This paper develops a different closure: the missing term may be the finite relaxation of spacetime geometry itself. Starting from the full time-dependent Virial Theorem, the normally discarded non-equili...

Spacetime Has a Relaxation Time: A Constitutive Completion of Weak-Field Gravity

Starting from the retarded solution of linearized General Relativity and coarse-graining over galactic scales, a minimal constitutive law emerges — one that requires no new particles, only a finite relaxation time for the weak-field geometric response. The same framework predicts...

Dark-Sector Phenomena as a Geometric Response: A Constitutive Theory of Weak-Field Gravity

This work develops TIDE as a constitutive theory of weak-field gravity. It explores the idea that spacetime geometry may not always track baryonic matter instantaneously, but can relax toward equilibrium over a finite time. In that interval, residual geometry can be read observat...

Lensing Excess as a Geometric Projection: A No-Refit Prediction with \(A_{\rm rel}=19/15\)

We test whether the galaxy-galaxy lensing excess (where light appears to cross more geometry than massive tracers) follows a universal geometric conversion rather than a fitted dark matter halo amplitude. Derived from tensor projection identities, the leading optical closure pred...
