 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) (where they are shown to be in Burnham Park, near Soldier Field, then 1 kilometer (103 m) (where we see the entirety of Chicago), and so on, increasing the perspective 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, revealing a skin cell and zooming in on it—until the camera comes to quarks in a proton of a carbon atom at 10−16 meter.
