What if the Moon Didn't Exist is a collection of speculative articles about different versions of Earth, published in book form in 1993. They were originally published in Astronomy magazine.
Contents The individual scenarios are:
Solon – Earth without a Moon Lunholm – Moon closer to Earth Petiel – Earth with less mass Urania – Earth's axis tilted like that of Uranus Granstar – More massive Sun Antar – Effects if a supernova exploded near Earth Cerberon – Star passing through the Solar System Diablo – Black hole passing through the Earth Seeing the world via infrared Effects of ozone layer depletion
Reception Reviews in Publishers Weekly and Kirkus said that the first several stories were interesting, but noted that the conceit grew repetitive.
