No Primordial Gravity: Probability Shear as the Origin of the Cosmic Vortex.

This paper presents a speculative extension of Wave Origin Cosmology (WOC), proposing that gravity was not a primordial feature of the universe but emerged only after the formation of physical structure. The framework proposes that the universe originated through shear instabilities within a primordial pool of probability waves, rather than through gravitational collapse. Drawing a conceptual analogy to Kelvin–Helmholtz instability in fluid dynamics, the paper explores how differences in probability-wave phase flow could generate organized vortical structures without requiring an initial gravitational attraction. Within this interpretation, our universe represents a cosmic vortex formed through probability shear, while gravity emerges subsequently through processes associated with folding entropy and the development of physical construct. The paper examines the conceptual implications for cosmological singularities, early-universe structure formation, and the emergence of gravitational behavior. It also identifies potential observational constraints involving primordial vector modes, parity asymmetries, cosmic microwave background polarization, and large-scale cosmological structure. This work is presented as a theoretical hypothesis rather than an established physical model, with emphasis on its conceptual foundations, relationship to existing cosmological observations, and potential avenues for falsification.
