Abstract
This paper presents a theoretical framework examining the potential connection between quantum-scale phenomena and cosmic-scale events through a primordial bridge between universes. Through thought experimentation in the tradition of Einstein, we explore how fundamental aspects of our observed universe—from quantum entanglement to dark matter distribution—could be emergent properties of a singular cosmic event involving the interaction of two universes via an Einstein-Rosen bridge. This work does not aim to make definitive predictions but rather to stimulate new approaches to understanding universal interconnectedness and the relationship between quantum and cosmic phenomena.
