What If the Earth Had Two Moons?: And Nine Other Thought-Provoking Speculations on the Solar System
“What if?” questions stimulate people to think in new ways, to refresh old ideas, and to make new discoveries. In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways.
The ideas alone get a minimum three+ stars in my reckoning. I've always liked SF stories that took me to truly weird worlds like Mesklin (Mission of Gravity) or Helliconia (Helliconia: The Classic Epic Trilogy in One Volume) and how the environments shaped the natives and the humans who (sometimes) colonized them. So in this book we get 10 scenarios about what an Earth-Moon system would be like if something were changed:
1. What if the Earth had two moons?
2. What if the Ear ...more
Parts of it were interesting, but nothing is really gained by reading the introductory vignettes. Unlike others, I won't criticize the renaming of the different scenario planets because of the way the names were subsequently used in the discussion. Thanks to the unknown library patron who pointed out the mistakes in the text which I had glossed over. Actually, some of the information was dated, even for 2010. Perhaps it's a consequence of the chapters having been written separately.

I am not happy with this book.
To be sure, the subject -- the question of what an earthlike world would be like if it had formed and evolved in different circumstances than ours, and what life would be like on such worlds -- is fascinating. Comins presents ten such scenarios:
1) What if the Earth had two moons?
2) What if the Earth were a moon?
3) What if our Moon orbited backwards?
4) What if the Earth's crust were thicker?
5) What if the Earth w ...more
