Patricio A. Gallardo

Patricio A. Gallardo is a researcher known for his critical analysis in the context of UAP-related scientific claims. He gained prominence by debunking Harvard astronomer Avi Loeb's assertion that metallic spherules recovered from the Pacific Ocean floor were of interstellar origin, potentially linked to extraterrestrial technology. Gallardo demonstrated that the spherules' elemental and isotope composition, including the 'BeLaU' pattern and rare earth elements, closely matches coal ash from standard NIST SRM1633a, a product of terrestrial industrial activity. His work appeared in discussions on Big Think, highlighting uncertainties in Loeb's meteor trajectory and spherule origins. No birth/death years, nationality, or additional UAP publications are detailed in available sources. Gallardo has been featured on the 'Starts With A Bang' podcast discussing related science.
