The Quantum Rupture Hypothesis

This paper introduces the Quantum Rupture Hypothesis (QRH), a speculative cosmological model proposing that a universe may originate from a spacetime rupture inside an ultra-massive parent black hole. Rather than suggesting that every stellar-mass black hole can generate a daughter universe, the model introduces a selective mass-energy threshold: only black holes that grow into the supermassive or ultra-massive range could plausibly approach the internal conditions required for a quantum-gravitational transition. In observational terms, this places the relevant candidate class in the approximate range of millions to hundreds of billions of solar masses, while avoiding a direct one-to-one conversion between the total mass-energy of the observable universe and the mass of any single known black hole. At such a threshold, classical gravitational coherence may break down into a quantum-dominated interior, producing a rupture that seeds a new expanding spacetime. The model interprets vacuum tension as a possible origin of dark energy and early frozen fluctuations as a possible origin of dark matter. Finally, it identifies Messier 87 and its central black hole, M87*, as the nearest well-studied large-scale observational archetype: a directly imaged supermassive black hole of about 6.5 billion solar masses, approximately 55 million light-years away, suitable for framing the hypothesis in measurable astrophysical terms.
