This study reinterprets natural phenomena by assuming the universe as an ocean of temperature-induced contraction pressure (cold pressure) referenced to absolute zero, and by focusing on the principles governing the generation and transformation of waves and motion (flows) within this environment. Waves are defined as phase changes of force (energy) resulting from the loss of directional coherence, whereas motion is defined as the sustained propagation of force (energy) with preserved directionality. Through these definitions, waves and motion are unified not as distinct physical quantities, but as different phase states of the same energy. This framework provides a unified explanatory basis for a wide range of macroscopic and microscopic phenomena—including sound, vibration, heat, light, electromagnetic radiation, fluid flow, material formation, and celestial structures—within a common pressure–phase–flow paradigm. By complementing conventional thermodynamic and particle-centered interpretations, this study proposes a new perspective in which natural phenomena are understood as cyclic structures governed by pressure and phase transitions.
