In 2023, avi-loeb’s galileo-project used magnetic sleds to retrieve hundreds of small metallic “spherules” from the Pacific Ocean floor near the presumed crash site of a 2014 bolide/meteor. Loeb suggested the spherules could be of extrasolar-planet or alien-technology origin. Other scientists countered that the material is more likely volcanic rock or industrial coal/fly ash, a claim not resolved as of this source.
