Loeb's team claims Pacific spherules have an extrasolar origin
Avi Loeb and 33 co-authors posted a preprint saying some seafloor spherules from their June 2023 expedition off Manus Island had an unusual 'BeLaU' composition suggesting an extrasolar source. Other researchers argued the grains matched coal ash or ordinary sources; Loeb disputed that.
