IM1 spherule / seismic critiques.

Body of peer critiques against the BeLaU-extrasolar claim: composition has terrestrial/cosmic analogs; 2025 study blames locating seismic signal on a truck.
A formal critique (arXiv 2311.07699) argued no link in Loeb's interstellar chain survives scrutiny. Meteor specialist Peter Brown said nothing solid survives a >28 km/s entry. The BeLaU pattern was shown to resemble ordinary cosmic spherules, Antarctic micrometeorites, and coal fly-ash. Most damaging, a 2025 LPSC analysis ('Probably Not Aliens') attributed the seismic signal used to fix the search box to a truck near a Manus Island seismometer.
