This research paper introduces a novel framework modelling space-time as a compressible fluid, unifying general relativity, quantum mechanics, and cosmology. Gravity emerges from pressure gradients as mass creates low-pressure voids in the fluid. Time is entropy flow, with dilation in suppressed entropy regions. Black holes are cavitation zones with finite-density cores, resolving singularities, while wormholes form stable pressure tunnels without exotic matter. Quantum phenomena, like entanglement and tunnelling, arise as fluid oscillations and pressure collapses. The model derives Einstein’s field equations as a fluid state law and accurately predicts planetary orbits, such as Mercury, Mars, Venus, and Earth (e.g., Earth’s orbit within 0.011% error) (Appendix B), aligning with observations like lensing and redshift. Novel predictions include chromatic lensing, gravitational wave echoes, and CMB anisotropies. This intuitive, observationally robust theory offers a cohesive framework for understanding the universe’s fundamental dynamics across scales.
