A Reinterpretation of Cosmic Origin Based on Light-Centered Fluctuations

This paper proposes a conceptual framework in which time is treated as an intrinsic attribute of light, rather than as an independent fundamental dimension.Within this perspective, the pre–Big Bang state of the universe is described not as a fluctuation of space and time, but as a pure fluctuation of light itself, governed by the same physical principles as the present universe. By interpreting quantum uncertainty as a universal physical law applicable even prior to cosmic birth, we argue that energy fluctuations possess a critical threshold. The Big Bang is then interpreted as a transition in the descriptive regime of fluctuations, analogous to a phase transition, rather than as a singular emergence from absolute nothingness. This approach, referred to as Light-Based Cosmology, offers a unified and aesthetically minimal interpretation of cosmic origin, avoiding unnecessary assumptions about pre-existing temporal structure while remaining consistent with established physical laws.
