Abstract
This paper presents the concept of Stochastic Zero, a mathematical framework designed to model time as a stochastic variable in physical systems. This approach is especially relevant for high-volatility experiments, where temporal uncertainties and phenomena like 'negative time' are observed. By complementing traditional methods such as Itô calculus, Stochastic Zero provides a balance of accuracy and flexibility in capturing temporal fluctuations. The simulations highlight how this framework offers deeper insights compared to conventional models, particularly in quantum systems characterized by significant temporal variability.
