Don't Know Much About Space - Tapa dura

If Earth is round, why don't people on the other side of the world fall off? (see page 26) Is Mars red because it's embarrassed? (see page 49) If black holes are invisible, how do we know they're there? (see page 86) Using the popular style that has won millions of readers, best-selling author Kenneth C. Davis blasts off for the stars! With an entertaining question-and-answer format, amusing anecdotes, and fact-filled sidebars, he sets his sights on the mysteries of space.
