Science and sci-fi collide in What If Earth Had Two Moons?: And Nine Other Thought-Provoking Speculations on the Solar System, a new book from University of Maine professor of physics and astronomy Neil Comins that theorizes about the possibility of life on an Earth thrown willy-nilly into physical scenarios other than the existing one. Comins toys with our planet's axis, its age, its mass and more, and in turn, the speculations spread to the rest of the universe and the idea that somewhere out there, there's another planet with conditions ideal for supporting life. And he does all with a contemporary sleight of hand supported by the latest scientific research.
Maybe it's just a twist of fate, but Comins will ask the question What if? tonight at 7:30 p.m. when he discusses and signs the book at the Tattered Cover LoDo, 1628 16th Street; for more information, go to www.tatteredcover.com or call 303-436-1070.
