Controversial astronomer celebrates spectacular discovery - but a researcher finds embarrassing mistake. Astronomer Avi Loeb is said to have been looking in the wrong place.

Sound waves probably don't come from a meteor, but from a truck. Material from the sea floor could be “normal” meteorites, researcher says. The team has also identified a more suitable location to search for the meteorite fragments, which is more than 100 miles (160 kilometers) from the actual search location. The study has not yet been reviewed by experts; it is available on the preprint server ArXiv.
