What if the history of Earth can be read like music?
In Settled Science Heresy Volume 4: Rock Music, Richard L. Kennedy examines the possibility that the geological and extinction cycles of Earth may follow harmonic relationships similar to those found in sound, resonance, and musical structure.
From extinction timelines and impact events to standing waves, Schumann resonances, orbital cycles, and recurring numerical ratios, this provocative volume explores whether the planet itself behaves less like a random system and more like a resonating instrument.
Blending geology, astronomy, mathematics, harmonics, and pattern analysis, Rock Music investigates:
- Major extinction cycles and recurring ratios
- The 27.5-million-year extinction pattern
- Harmonic relationships in geological eras
- Schumann resonances and Earth's electromagnetic "hum"
- Fractal repetition across scales
- Orbital cycles and planetary resonance
- The possibility that Earth operates as a harmonic system
Rather than presenting geology as chaotic coincidence, Kennedy asks whether recurring structures hidden within Earth's history point toward a deeper organizing principle.
Accessible, thought-provoking, and visually rich, Rock Music invites readers to reconsider the possibility that the Earth may be keeping time to a song humanity has only begun to hear.
