Just watch it, it’s neat.
Powers of Ten is a 1968 American documentary short film written and directed by Charles and Ray Eames. The film depicts the relative scale of the Universe in factors of ten. The film is an adaptation of the book Cosmic View (1957) by Dutch educator Kees Boeke.
The film begins with an overhead view of a man and woman picnicking on a lawn — a one-meter-square overhead image of the figures on a blanket. The viewpoint, accompanied by expository voiceover by Philip Morrison, then slowly zooms out to a view ten meters across (or 101 m in scientific notation). The zoom-out continues (at a rate of one power of ten per 10 seconds), to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place in Burnham Park, near Soldier Field on Chicago’s lakefront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in at a rate of a power of ten per 2 seconds to the picnic, and then slows back down to its original rate into the man’s hand, to views of negative powers of ten—10−1 m (10 centimeters), and so forth—until the camera comes to quarks in a proton of a carbon atom at 10−16 meter.
