In this engaging and accessible exploratory work, accomplished astrophysicist Neil F. Comins shows how ten hypothetical astronomical situations would affect our planet and life on it. What if the Moon didn't exist, for example? The Earth would be rotating much faster than it presently does, tides would be lower, and life would be much more primitive than it is today. "What if the Moon Didn't Exist?" has been made into TV, radio, planetarium, and theater shows, and became the theme to Mitsubishi's pavilion at the World Expo in Nagoya, Japan in 2005.

It takes a rare writer to manipulate so many unknown factors with such ease and convincing detail. This book will thrill everyone who can't help wondering "what if..." -Astronomy Book Club
