As humanity approaches a pivotal transition in planetary evolution, a new scientific and conceptual framework is required—one that goes beyond conventional models of psychology, physics, and technological advancement. Transliminal phenomena, which describe interactions and processes occurring across perceptual, cognitive, and physical thresholds, are central to understanding the next phase of planetary and human development. Redefining Transliminal Phenomena in Planetary Evolution The term transliminal signifies processes that move beyond existing thresholds—whether they be cognitive, environmental, energetic, or systemic. In the context of higher-order planetary evolution, this implies a shift from a closed-system planetary model to an open-system evolutionary model where adaptation, integration, and expansion drive progress. This transition requires a reevaluation of science, consciousness, and planetary systems as interconnected domains of study rather than separate disciplines. Tra
