Title Push-Field Theory of Gravity: A Unified Framework for Dark Matter and Dark Energy Description Abstract This paper presents a novel theoretical framework in which gravitational attraction emerges not from a direct pull between masses, but from pressure gradients in a universal scalar field. This "push-field" mechanism provides a unified explanation for three major cosmological puzzles: dark matter, dark energy, and cosmic acceleration. The theory introduces a scalar field \phi(x,t) that fills spacetime, naturally excited in vacuum but stabilized by the presence of mass. Key Theoretical Contributions * Unified Mechanism: Proposes that gravitational attraction is a "push" arising from pressure gradients, where matter is pushed from high-pressure vacuum regions toward low-pressure regions near masses. * Dark Matter Alternative: Non-linear self-interactions of the field produce enhanced gravitational effects in dense stellar regions, naturally reproducing observed galaxy rotation curves without invoking dark matter particles. * Dark Energy & Cosmological Constant: The mechanism generates cosmic acceleration through field pressure, addressing the cosmological constant problem through dimensional transmutation. Validation and Results * Solar System Tests: The theory demonstrates agreement with solar system tests, showing less than 0.01% deviation from General Relativity. * Galaxy Rotation Curves: Detailed numerical predictions fit galaxy rotation curves (e.g., Milky Way) using universal parameters (\lambda \approx 5 \times 10^{-37} and \beta \approx 5 \times 10^{-20}). * Cosmology: The model matches the \LambdaCDM Hubble parameter evolution to within 2% at redshifts z < 10. Testable Predictions The paper outlines specific predictions that distinguish this framework from \LambdaCDM, including: * Gravitational Lensing: Enhancement is strongest where visible matter is densest, rather than following extended dark matter halos. * Wide Binary Stars: Predicted Newtonian dynamics for isolated wide binaries (separation > 10^4 AU) with no gravitational enhancement. * Pulsar Timing: Specific timing residuals expected in dense stellar environments like globular clusters.
