This experimental physics paper refutes General Relativity (GR) and Thermodynamics by empirical tests that contradicted its predictions. We demonstrate that GR’s foundational dependency, Maxwell’s Equations, fails in three-dimensional systems where magnetic repulsion is geometrically impossible and we provide empirical evidence that heat is a vectorial attractive force capable of generating negentropy. Our experiments reveal that "Gravity" is the macroscopic manifestation of two distinct attractive forces: (1) 3D Magnetic Alignment, which governs solid bodies and precludes stable repulsion, and (2) Thermal Attraction, demonstrated by the "antigravitational" flow of fluids toward heat sources. We present a new cosmological framework where elliptical orbits are resolved not as a product of curved spacetime, but as the dynamic equilibrium between magnetic alignment (structural lock) and thermal attraction (orbital pull).

Planetary Atmospheres as Gravitational Tests Prediction from Pure Mass-Based Gravity: Atmospheric retention should correlate with surface gravity (g ∝ M/R²) Observation: Planet Mass (% Earth) Surface g (% Earth) Atmosphere (% Earth) Core Temp Mars 10.7% 38% 0.0005% Cold Earth 100% 100% 100% Hot Venus 81.5% 90% 9,000% Hot Conclusion: Mass-based gravity alone cannot explain 21,000x atmospheric deficit on Mars or 100x atmospheric surplus on Venus. Core temperature correlates perfectly. Implication: Thermal component to gravitational attraction confirmed by planetary atmospheric data.
