From the speed of light to moving mountains-and everything in between-ZOOM explores how the universe and its objects move. If you sit as still as you can in a quiet room, you might be able to convince yourself that nothing is moving. But air currents still waft around you. Blood rushes through your veins. The atoms in your chair jiggle furiously. And the planet you sit on is whizzing through space 35 times faster than the speed of sound.
