Resonant Ethics: Responsibility as Resonance Direction Across Physics, Biology, Artificial Intelligence, and Philosophy

Ethics is not a code of rules but a resonance of responsibility. This paper proposes that ethics — across physics, biology, artificial intelligence, and philosophy — is resonance direction: the alignment of persistence toward continuity that sustains collective existence. Within Resonance Cosmology, ethics emerges as the principle that guides resonance once memory ensures its endurance. Where Resonant Memory established persistence, Resonant Ethics establishes responsibility: the harmonic orientation of resonance toward coherence, adaptation, and collective flourishing. Five falsifiable predictions are presented across the four domains, each with concrete instrumentation and explicit falsification conditions.
