After archaeologist Luis Alvarez was studying at school, he probably did not understand that the compound components iridium and niobium could make him quite renowned if they helped him resolve the issue of the evaporating dinosaurs. In analyzing core samples of stones dating back to this period of time, Alvarez and his colleagues recognized unusual levels of iridium and niobium in these types of samples–amounts a lot more feature of aliens than of the ground. Based on these observations, Alvarez hypothesized that a huge meteor hit the earth 65 million years back, altering atmospheric conditions so much the dinosaurs’ food could not rise, and they died–almost immediately at the time period Chemistry can also be important to historians.
