Identifies more than 1,700 common misconceptions about science and nature and discusses their origins, from incomplete reasoning to sensory misperception.

Explores how the earth would be different in ten alternative astronomical conditions, including how the planet would change if there was a second moon, if the moon orbited backwards, if the earth's crust were thicker, if there was a counter-Earth, if the sun were less massive, and if there were two suns.

Physicist and astronomer Neil F. Comins provides a guide to outer-space travel, and describes that although tourist trips will probably become the norm, there are risks and challenges that tourists will have to face.
