The L'Aigle meteorite fall shifts scientific opinion

Background. Before the L'Aigle event, meteorites were generally considered a superstition and mistrusted by the scientific community. Ernst Chladni had theorized in 1794 that meteorites originated beyond Earth, but the mere existence of meteorites was harshly debated. Very few scientists truly believed that rocks found on Earth could have extraterrestrial origins prior to Biot's investigation.

Biot's Investigation. Jean-Baptiste Biot, a French physicist and astronomer, was sent by the Académie française to report on the meteorites that fell on L'Aigle. His thorough investigation concluded that the stones must undoubtedly be of extraterrestrial origin. This paper effectively gave birth to the science of meteoritics and established the reality of meteorites.

Scientific Impact. The L'Aigle event was a milestone in the understanding of meteorites. It shifted scientific opinion from mistrust to acceptance of extraterrestrial origins. Biot's report explored the cradle of meteoritics, confirming that rocks found on Earth could indeed have extraterrestrial origins, contrary to prior beliefs.
