A Nonlinear Vibrational Equation for the Coherent Origin of Space Time

his preprint introduces the Domingo Cuevas-Andújar Theory of the Divine Thunder (TDCAED), an original cosmological framework proposing that the origin of the universe is not the result of a random quantum fluctuation of the vacuum, but a coherent primordial vibrational event called the “Divine Thunder” (Estruendo Divino). The theory is formalized through the following nonlinear scalar field equation: vdivino2∂2Ψ∂t2−∇2Ψ+αΨ3=0v_{\text{divino}}^2 \frac{\partial^2 \Psi}{\partial t^2} - \nabla^2 \Psi + \alpha \Psi^3 = 0vdivino2∂t2∂2Ψ−∇2Ψ+αΨ3=0 The paper presents: Detailed mathematical analysis of the equation Derivation of the effective potential Soliton-type solutions Cosmological interpretation of the Divine Thunder Conceptual diagram of the primordial event Comparison with the standard Big Bang model Testable predictions The TDCAED offers a unifying approach that combines theoretical physics (nonlinear wave equations and field theory), cosmology, and the principle of fundamental cosmic coherence, suggesting that order and structure were present from the very beginning of the universe.
