The theory unifies asymptotic modified Newtonian ‎gravity with quantum mechanics within an orthogonal four-dimensional framework that opposes intrinsic spacetime ‎curvature and eliminates gravitational singularities. This paper presents three physical applications of Absolutivity theory: ‎black holes and Hawking radiation, four-dimensional harmonics wave theory, and the mass-gravity property. For black holes ‎and Hawking radiation, Absolutivity predicts a hidden vacuum area located between the massive core and the Schwarzschild ‎radius. Within this region, both photons and mass particles can orbit according to Lagrange's principle of stationary action. ‎Photons experience curvature in a gravitational field without requiring an attractive force, as they possess no mass-gravity ‎property. The theory supports the existence of Hawking radiation from a classical continuum perspective but does not predict ‎complete evaporation of the black hole core. In four-dimensional harmonics wave theory, the true spacetime topology allows ‎energy to ingress from three independent spatial directions toward a single spacetime point. This yields a theoretical energy ‎concentration higher by a factor of the square root of three compared to the one-dimensional Mizohata-Takeuchi conjecture. ‎The treatment emphasizes that dimensional density of energy must be properly accounted for in harmonic analysis. ‎Regarding the mass-gravity property, the gravitational potential field of a particle is shown to be velocity-dependent. As a ‎particle approaches the speed of light, its gravity field becomes confined within the particle structure and cannot radiate ‎outward. Consequently, measurements of gravitational potential fields cannot provide an accurate estimate of the total mass ‎present in the universe. These applications demonstrate that Absolutivity offers a deterministic, causality-embedded, non-‎curved spacetime framework capable of addressing both quantum and astrophysical phenomena.‎ 06 2026 25 34 10.55672/hij2026pp25-34 https://hscience.org/index.php/hij/article/view/198
