Astrophysicist Neil deGrasse Tyson explores a range of intriguing topics in his new book, “Just Visiting This Planet, Revised and Updated for the Twenty-First Century: Further Scientific Adventures of Merlin from Omniscia.” The book features the character Merlin, an alien Tyson introduced earlier in his career, and aims to engage readers with a mix of humor and scientific inquiry.
During an appearance on “CBS Mornings,” Tyson discussed how the nature of questions he receives has evolved. He notes that while previous inquiries tended to focus on basic facts, contemporary questions are often more whimsical and imaginative. For instance, Tyson poses the hypothetical scenario: “If aliens came and exploded the moon, what effect would that have on us?” He elaborates on the moon’s historical significance, suggesting that it played a crucial role in the development of early life by facilitating isolated tide pools.
Tyson is clear about the search for extraterrestrial life. He emphasizes the scientific consensus regarding the potential for life beyond Earth but expresses skepticism about claimed alien visits. He points out that with the proliferation of high-resolution cameras, it seems implausible that no clear evidence has surfaced.
The book also simplifies various scientific curiosities, such as the mechanics of leap years. Tyson explains the nuances behind leap year corrections, noting the necessity to adjust for over-corrections that occur every century. Additionally, he tackles the popular “Superman” myth of reversing Earth’s rotation to turn back time, dismissing it as impossible due to the independent nature of time and Earth’s rotation.
Illustrated by Tyson’s brother, the book promises an engaging journey through the cosmos, celebrating humanity’s insatiable curiosity. “Just Visiting This Planet” is set for release on Tuesday, inspiring readers to ponder scientific wonders with a renewed sense of imagination and fun.
