P0 Theory: The Nothingverse — Time Singularity, Nothons, and Emergence of Spacetime

Recent experimental probes have reached ∼ 100 billion times smaller than an atom, a regime termed the “zeptoverse”. We argue this is not the fundamental limit. The ultimate infinitesimal limit of nature is not spatial but temporal: the limit of a single moment in time, a state of nothingness. We formalize this as N0: The Silence, a pre-spatiotemporal potential substrate at dT = 0, populated by virtual quanta of potential called nothons N o. Spacetime gµν is not fundamental but emergent via a threshold phase transition at P0: The First Breath, defined by nothon density ρ > ρc. We call the total structure the Nothingverse — a nothing-universe that is in reality a creative universe. We propose that time is ontologically prior to space, matter, and law, and that the only truly fundamental measurement is that of a single moment. All other measurements are secondary and derived. We derive the emergence equation, unify the zeptoverse as a deep-gµν regime, and make7 falsifiable experimental predictions for collider, gravitational-wave, quantum-clock, andcosmological tests.
