Quantum Holographic Consciousness Theory (QHCT): A Lagrangian Formulation of an Interference-First Holographic Framework and Planck-Oriented Validation

We introduce Quantum Holographic Consciousness Theory (QHCT), a framework that places interference, rather than collapse or causal power, at the center of conscious experience. In this view, the universe behaves like a vibrating holographic screen, carrying patterns that exist prior to observation. Consciousness does not inject energy into these patterns, but acts as a frequency-sensitive reader that selects and stabilizes them into lived experience. We tested this idea at two scales. Cosmologically, Planck 2018 data reveal node-like regularities and phase linearity, signatures of holographic interference. Physiologically, heart-rate variability records display few-mode concentration, selective phase entrainment with respiration, and low-dimensional reconstructions. These findings jointly suggest that both cosmic background radiation and human physiology can be interpreted as mode-limited interference structures. QHCT thus offers a falsifiable cross-domain framework, tested on both cosmological and physiological data, that bridges physics, neuroscience, and philosophy of mind in a coherent account of consciousness.
