Moon Sheds Light on Earth’s Impact History

The video discusses the asteroid impact that caused the extinction of dinosaurs and highlights that Earth has experienced nearly 200 impact craters. It questions whether the impact rate has changed over time, noting a speed-up around 290 million years ago. This could be due to older craters being erased by natural processes. To verify, scientists study the Moon, which shares Earth's impact history but preserves craters better. Using data from the Lunar Reconnaissance Orbiter, they confirm the increased impact rate is real, not just an artifact of Earth's record. The Moon serves as a time capsule, offering insights into Earth's geological history.
