On the illusion of the geometry of spacetime and the dynamic vacuum theory of gravitation

[IN REVIEW NOW] Gravitation is a fundamental phenomenon experienced every moment of our existence, and yet we have not been able to decipher its profound functioning at the quantum and cosmic levels of the universe. The current general relativistic interpretation through curved spacetime, guided by the metric tensor, among others, in Einstein's equations, combined with the search for quantum gravity, creates insurmountable obstacles to the unification of spacetime with quantum fields, oscillating based on the vacuum energy. Therefore, the dynamic vacuum concept is introduced, allowing the integration of quantum fields and spacetime (as emergent) into a single logical framework in the future modified QFT, and the new explanation of gravitation as the thermodynamic tendency of compact, energy-denser systems to follow gradients in the vacuum, tending to the state of least energy difference. The emphasis is on conceptual and intuitive cause- and-effect reasoning and the theory of gravitation as a continuum resulting from the slight modifications of Kepler's third law. Consequently, all the content of the universe — baryons, radiation, dark matter and dark energy, as well as gravitational effects, are unified in one energy content, eliminating the need for dark sector, leading to simplifications in resolving mysteries like the core-cusp anomaly, Bullet cluster case, the cosmic coincidence and cosmological constant problems, and others, including the strange connection between MOND's acceleration and the Hubble's constants. This unification frame is mathematically validated by deriving Hubble's law directly from the new gravitational formula, laying the groundwork for a new model of cosmology.
