Cosmology of Unity: The Three Doors, the Five Variables, and the Breath of the Universal Harmonic Oscillator

The Cosmology of Unity introduces a scalar-field framework (Neutromatherion) that integrates matter, energy, gravity, time, and space as harmonics of a universal oscillator. This approach extends the standard Friedmann equations by incorporating a reactive coupling term gNT, generating a dynamic negative pressure that replaces the cosmological constant. Empirical calibration demonstrates that the model reproduces galactic rotation curves (SPARC database) without invoking non-baryonic dark matter, and matches the acoustic peaks of the Cosmic Microwave Background (Planck mission data). Laboratory predictions include measurable frequency shifts in optical lattice clocks and low-energy resonances in controlled vacuum experiments. Conceptually, the framework interprets cosmic evolution as a respiratory cycle: expansion (Luminous Door), contraction (Dark Door), and renewal (Neutral Door). Rather than discarding established physics, the Cosmology of Unity integrates mathematical rigor with philosophical coherence, proposing that measurable phenomena and human interpretation are complementary aspects of the same universal breath.
