The Meteorite Test

In this video, physicist Paul Steinhardt discusses the discovery of quasicrystals with a meteoritic origin. By measuring oxygen isotopes, scientists determined that these quasicrystals came from a specific type of meteorite, CV3 carbonaceous chondrites, which formed in the early Solar System. The video highlights the high-pressure formation of these materials and the collaborative efforts with Caltech to achieve these findings.
