The origin of spacetime and the physical mechanism driving late-time cosmic acceleration remain open questions in modern cosmology. This publication presents the Kuva Theory, a phenomenological framework in which the Universe originates from a finite energetic state existing prior to spacetime itself. The model introduces an effective scalar field, referred to as the Kuva field, which governs both the emergence of spacetime and its subsequent expansion. A two-stage dynamical behavior naturally arises: an initial force-driven transition from a pre–geometric regime to an expanding spacetime, followed by a residual horizon-scale force that contributes to late-time acceleration. The resulting energy behavior mimics a dark-energy–like equation of state without invoking a cosmological constant or an explicit dark energy component. The Kuva Theory is intended as a complementary description to standard cosmology, offering an alternative physical interpretation of cosmic acceleration and non-singular cosmic origin.
Motivation for a Pre–Space-Time Cosmological Framework
Standard cosmological models successfully describe the large-scale evolution of the Universe, yet they rely on assumptions that leave fundamental questions unresolved. The presence of an initial spacetime singularity and the introduction of dark energy as an unexplained component highlight the need for alternative physical interpretations. The Kuva Theory addresses these challenges by proposing a cosmological description that precedes spacetime itself.
The Kuva Scalar Field and the Pre–Geometric Regime
The Kuva framework assumes the existence of a physical regime prior to spacetime, where conventional geometric quantities are undefined. This pre–space-time regime is modeled as a homogeneous scalar field carrying finite latent energy, referred to as the Kuva field.
Two-Stage Kuva Force Dynamics
A defining feature of the Kuva Theory is its two-stage dynamical structure. In the first stage, an intrinsic force initiates spacetime emergence. In the second stage, a residual horizon-scale force persists, influencing large-scale cosmic expansion.
Horizon-Scale Energy and Cosmic Acceleration
The residual force scales with the cosmological horizon, producing an energy behavior that leads to an approximately constant effective energy density and accelerated expansion without invoking dark energy.
Relation to Standard Cosmology
At the level of background expansion, the Kuva Theory remains compatible with standard Friedmann cosmology and observational constraints.
Conclusion: Toward a Non-Singular Origin of Cosmic Expansion
The Kuva Theory presents a non-singular, force-driven framework for cosmic origin and acceleration, offering an alternative interpretation that complements standard cosmological models.
