A cosmological hypothesis about the state before the Big Bang – a void that is not empty but a quantum‑gravitational realm from which our universe emerged. The primordial void may have been a timeless, spaceless, or multidimensional entity that underwent a phase transition, tunneling event, or fluctuation to create spacetime and matter. It draws on ideas from loop quantum cosmology, string gas cosmology, and the Hartle‑Hawking proposal. The theory seeks to explain why the universe exists at all and why it has the properties it does.
