The Cosmic Hum Hypothesis: A Resonant Information Framework for Detecting Technological Civilizations

This working paper introduces The Cosmic Hum Hypothesis, a speculative yet coherent framework proposing that technologically active civilizations emit a detectable multi-layered resonance signature—an involuntary “cosmic hum.” Rooted in the Universal Theory of Resilience (UTR) and the informational view of physics, the hypothesis suggests that any system performing structured computation produces three distinct forms of detectable resonance: 1. Electromagnetic Hum – classical RF and thermal leakage. 2. Informational Resonance Hum – non-random, high-complexity field patterns generated by structured computation. 3. Dual-Universe Shadow Hum – subtle interference structures arising from mirrored informational processes in a dual-domain cosmology. Together, these layers form a new pathway for the Search for Extraterrestrial Intelligence (SETI) that does not require intentional communication. Instead of listening for targeted signals, this framework suggests focusing on background computational resonance that would naturally arise from any technologically active society. The Cosmic Hum Hypothesis reframes cosmic detection, offering fresh conceptual ground for future instrumentation and observational strategies.
