Earth as a time crystal: macroscopic nature of a quantum-scale phenomenon exposes quantum physics as tidally-resonantly localized to host star

Abstract: Claims of paleodata periodicity are many and so controversial that superimposing Phanerozoic (0-541 My) mass-extinction periods renders life on Earth impossible. This period hunt coincided with geochronology modernization tying geological timescales to orbital frequencies, enabling separation of astronomical signals from harmonics. I thus show on diverse data (geomagnetic polarity, cratering, extinction episodes) as a proxy of planetary paleodynamics that many-body subharmonic entrainment induces Earth's resonant response to astronomical forcing so that 2{\pi}-phase-shifted axial precession p=26 ky and its Pi=2{\pi}p/i; i=1...n harmonics get resonantly responsible for paleodata periodicity. This quasiperiodic nature of strata is co-triggered by a p'/4-lockstep to p'=41-ky obliquity. For verification, residuals analysis after suppressing 2{\pi}p (and so Pi) in GPTS-95 polarity reversals timescale's calibration at the South Atlantic Anomaly, extending to end-Campanian (0-83 My), successfully detected weak signals of Earth-Mars planetary resonances reported previously from older epochs. The only residual signal is 26.5-My Rampino period - carrier wave of crushing deflections and transformative reversals. While the Earth's (2{\pi}p, Pi) resonant response is the long-sought energy transfer mechanism of Milankovitch theory, fundamental system properties - 2{\pi}-phase-shift, 1/4 lockstep to a forcer, and discrete time translation symmetry (multiplied/halved periods) - typical of a quantum time crystal, appear macroscopic. The surprising cross-scale outcome confirms planetary precession is a cataclysmic geodynamic phenomenon claimed previously as the mechanism for Earth's reversals and expansion. As the Earth-Moon-Sun resonant system sets the tone for all subscale resonances like the quantum, quantum physics in any interpretation is fundamentally different and variable outside Earth's vicinity.
