We propose a unified framework in which all physical phenomena—from quantum mechanics to cosmology—emerge from a single principle: reality is composed of oscillations at characteristic frequencies across a fractal hierarchy of scales. The universe exhibits precise structural and dynamic symmetries spanning 61 orders of magnitude in length and 69 orders of magnitude in mass, with cellular scale (10⁻⁵ m) serving as the geometric center. We demonstrate that gravity, quantum mechanics, and cosmological structure are manifestations of the same oscillatory dynamics operating at different scales, connected through dimensional flows of information and energy.
