This study reinterprets the universe not as a collection of complex and independent laws, but as a continuum governed by a simple physical principle: resonant thermo-contraction pressure operating with reference to absolute temperature 0 K (–273 °C). Whereas conventional physics and cosmology have treated galaxy formation, gravity, electromagnetic phenomena, waves, and matter generation as distinct processes, this work proposes that these phenomena are different manifestations of a common contraction–rotation–resonance mechanism, realized under varying conditions and scales. From this perspective, the universe may be understood as a pressure-dominated space governed by cooling pressure, while galaxies function as resonant structures that buffer spacetime fluctuations. Gravitation, accordingly, is interpreted not as an active attractive force between masses, but as the result of pressure gradients formed as cosmic pressure acts to relax density differences. Furthermore, flows, rotation, waves, electron activation, and materialization are described as successive stages of continuous energy redistribution and resonance accumulation. Light and waves are redefined not as fixed entities, but as phase expressions generated through the interaction between thermal expansion and thermo-contraction pressure. High-energy radiation, including gamma rays, is understood as forming a boundary of the biological environment through ionization processes. In the domains of life and cognition, these resonant structures are likewise projected: sensation, judgment, and memory can be interpreted as dynamic processes arising from interactions between external stimuli and resonance conditions within neural systems. In conclusion, the electromagnetic rotational resonance cosmology proposed here is not intended to replace existing physical theories, but rather to serve as an integrative interpretive framework that addresses why established physical laws take the forms that they do.
