Part 8/10:
Peter shifted focus to evidence from other celestial bodies, particularly the moons of Jupiter and Saturn, such as Europa and Enceladus. Observations from space missions have revealed liquid and gaseous materials venting from beneath the crust, showcasing processes similar to Peter's theories on Earth's expansion. These events provide concrete examples of how moons might be experiencing similar phenomena to what Peter proposes for Earth, further validating his insights into planetary processes.
