Mathematics, Vibration, and Entropy: Three Intangible Fundamentals of the Cosmos

The observable universe emerges from three irreducible, intangible principles: mathematics (pure relational structure), vibration (fundamental oscillatory dynamics), and entropy (intrinsic directional irreversibility and increasing disorder). These three alone suffice to generate the full range of physical phenomena—from quantum fields to biological coherence to cosmological evolution—without requiring additional entities, fields, or constants. Mathematics provides the arena of possibility, vibration animates it with time and change, and entropy imposes an arrow that makes complexity and observer emergence non-accidental. This triad offers a minimal, unifying framework that is consistent with existing observations across scales and generates falsifiable predictions in quantum biology, cosmology, and cross-domain resonance phenomena. The paper presents the postulates, supporting evidence, and testable implications while leaving open the deeper question of why such principles exist and how they enable the emergence of observers capable of recognizing them.
