Einstein vs Reality

Einstein vs Reality" explores a provocative shift in physics, proposing that gravity is not the abstract curvature of an empty spacetime manifold, but the physical pressure of a tangible fluid medium. By treating space as a substance with a measurable density (\rho_{0}\approx0.3~kg/m^{3}), the paper demonstrates that fluid mechanics can reproduce Einstein's core successes—such as light bending and time dilation—with identical mathematical precision. The strength of this "reality-based" framework lies in its ability to eliminate the need for "exotic" patches like dark matter and dark energy, instead deriving them naturally from galactic vortex dynamics and accumulated entropy. Ultimately, the paper argues that nature repeats its patterns across all scales, suggesting that galaxies follow the same fluid laws as hurricanes and geysers because they are made of the same fundamental substance.
