Siavash Spacetime Dynamics (SSD): A Unified Geometric Solution to Dark Sector Anomalies via Dynamic Spacetime Generation

For over a century, modern astrophysics has been haunted by ghosts: Dark Matter and DarkEnergy. We have built our entire cosmological standard model (ΛCDM) on the premise that 95%of the universe is composed of invisible, undetectable entities. The Siavash Spacetime Dynamics(SSD) framework shatters this paradigm by introducing a radically elegant, baryon-only geometricsolution. SSD posits that spacetime is not a static background, but a dynamic, fluid-like metriccontinuously synthesized in extreme astrophysical environments, such as the core of galactic blackholes and hyper-dense stars. Through quantum tunneling and the inherent non-local nature ofspacetime, this newly forged metric is injected directly into lower-density intergalactic voids. Theresult is a profound dual-effect: the newly introduced spacetime, being denser than the surroundingvoid, exerts an external pressure gradient that confines stellar orbits within galaxies (resolvingthe Dark Matter illusion) while simultaneously driving galaxies apart (resolving the Dark Energyaccelerating expansion). Formulated with rigorous semiclassical mathematics, SSD successfully andindependently resolves nine of the greatest anomalies in modern physics. This paper provides thecomplete theoretical architecture and quantitative proof that the universe needs no dark entities; itsimply creates its own space.
