A Stiffness Field Cosmology: Light, Matter, Gravity, and Redshift from One Scalar

This work presents a non-origin cosmological ontology in which the universeexists without any initiating cause. The universe is described as a unified, ho-mogeneous, infinite, and intrinsically indeterminate energy field whose internaloscillations give rise to light, matter, gravity, and large-scale cosmic structure.A single evolving property—vacuum stiffness—governs oscillatory behavior, maxi-mum energy density, and structural stability. The model predicts a closed cosmiccycle composed of alternating stiffness-increasing and stiffness-decreasing phases,through which matter forms, dissolves, and reforms. This article develops the con-ceptual foundations of the framework without technical formalism and refers toseparate technical appendices for mathematical implementation.
