Conventional general relativity treats black holes primarily as endpoints of gravitational collapse where matter and information are lost. This paper proposes an alternative mechanical framework: black holes function as cosmic recirculation pumps that actively process and redistribute matter and energy — particularly dark matter — within a self-regulating universe. Central to the model is a gallium-like phase transition in dark matter near the event horizon from a stable solid elastic scaffolding phase into an agitated superfluid liquid state. Processed material is hypothesized to be recirculated through Einstein-Rosen bridge-like structures within dark matter folds and re-condensed elsewhere, sustaining galactic formation and cosmic expansion, giving black holes a purposeful regulatory role.
