It took 22 million years for these meteorites to land on Earth Share Updated: 12:04 PM EDT Apr 28, 2021 By Ashley Strickland Share Updated: 12:04 PM EDT Apr 28, 2021 Hide Transcript Show Transcript Uh huh. When a meteorite strikes, earth scientists think it might create an unexpected mineral. At the impact site, scientists found it may alter minerals where it crashed and create an unusual form of silica. A team led by a Carnegie Institute for Science researcher examined the crystal structure of the silicon mineral courts under shock compression. They mimicked a meteorite impact in a lab with a cannon light gas gun to accelerate projectiles into court samples faster than a bullet. They used X ray tools to figure out the crystal structure of material right after impact and found that courts undergoes a transition into a new crystalline structure. However, once the intense pressure subsides, it can t last. This challenges longstanding assumptio
