Bake a soufflé, and you'll never unscramble the ingredients again. Unless, that is, you twist the ends of a wormhole around several times and drive a rocket through it, traveling back to a time before you ever cracked an egg. In Time & Space, part of the Eyewitness Science series, you'll learn all about time travel, wormholes, and all the ways that the universe is thought to be constructed. Stand-ins from real life (like orange peels, broken glasses, and trains) help you figure out what Albert Einstein, Stephen Hawking, and other physicists mean when they refer to black holes, space-time distortion, and other strange cosmic things. Starting with ancient ideas about space and time, and ending with the imaginary construction of a wormhole through time, Time & Space takes you on a colorfully illustrated trip through history, with great photos of the tools people have used to measure time and distance in many cultures. This is a great starter book in astrophysics, and it will help you understand things like whether the universe has always existed, what star systems look like, and what would happen to you if you fell into a black hole.
