Cosmic Evolution via Gravitational Drainage: A Surface-Tension Driven Expansion Model

Cosmic Evolution via Gravitational Drainage: A Surface-Tension Driven Expansion Model is the first paper in the Gravitational Drainage Cosmology series. This paper proposes a novel macroscopic framework to resolve the logical impasses of standard cosmology: the Big Bang's trigger, the black hole singularity, and the nature of dark energy. Core Concept: The Phase Transition of Gravity While fully acknowledging Einstein's General Relativity for classical mass-energy curvature in non-extreme environments, this model introduces a strict physical limit to geometric curvature. We posit that at the extreme critical mass threshold of a black hole, the 3D spacetime membrane (Brane) ruptures. At this exact puncture event, gravity undergoes a "phase transition"—shifting from classical geometric attraction to fluid-dynamic suction. This localized suction is driven by the infinite pressure gradient between our universe and the absolute zero-energy external "Null Void." Key Proposals in this Paper: The Big Bang: Reinterpreted as a high-pressure mechanical injection event driven by infinite thermodynamic gradients. Dark Energy & Cosmic Expansion: Replaced by mechanical surface tension and "spacetime leakage" through black hole drainage channels, naturally explaining both cosmic expansion and its recent deceleration. Resolving the Singularity: The singularity paradox is eliminated by treating black holes as open, flow-through drainage valves rather than infinitely accumulating storage points. Hawking Radiation: Reinterpreted as the universe's self-healing mechanism, akin to surface tension closing a puncture in a soap film. Author's Note: This paper is built upon physical intuition, fluid-dynamic analogies, and conceptual visualization. As an independent researcher, the author acknowledges the lack of formal equations and leaves the rigorous mathematical formalization of this blueprint to experts in theoretical physics and quantum gravity.
