Abstract: We report the discovery of a fundamental cosmic frequency f0 = 6.676 × 10−10 Hz emerging from quantum temporal boundary conditions. The frequency shows 2.8σ significance in NANOGrav 15-year data and enables derivation of the gravitational constant from first principles (G = 6.674×10−11 m3 kg−1 s Ñ −2). Experimental verification demonstrates temporal emergence at 347.2 ± 12.8 s, supporting a participatory quantum cosmology framework where conscious temporal references act as quantum boundary conditions. All code and verification data are available at https://github.com/hrsmqphysicsdotcom/quantum_temporal_boundary
Héctor Ramón Sánchez Mendoza is an independent theoretical physics researcher based in Río Bravo, Tamaulipas, Mexico. Holding a degree in Economics, he spent over a decade as a top national sales executive and manager trainer in the banking and insurance sectors, developing an analytical expertise in forecasting and timing under pressure. Following a prolonged period of profound personal adversity, full-time family care, and strict isolation, he channeled his quantitative background into quantum foundations and cosmology. Transforming this challenging confinement into a rigorous space for theoretical inquiry, he modeled high-entropy empirical systems through thousands of iterative spreadsheet simulations. His research ultimately evolved into the formal cosmological framework presented in his preprint, "Quantum Temporal Boundary Conditions and Emergent Spacetime: From Conscious Reference Points to Cosmic Decoherence (DOI:10.5281/zenodo.17890809).
To date, his work exploring the derivation of the gravitational constant from first principles has organically surpassed 3,000 unique views and downloads on the Zenodo repository.
