The molecules fly at typical airplane speeds12 through the vacuum, one at a time,13 and fall about one millimeter in the gravitational field while traversing the apparatus, just as a macroscopic ball would at that speed. If we mentally scale up the experiment so that the buckyballs assume the size of normal soccer balls, they would be detected at the moon and the distance from one slit to the next would be about the size of a soccer field. What corresponds to the detection screen in Young’s 1802 experiment is, in the 1999 Vienna experiment, a movable stage that scans the width of the molecule stream with a laser beam pointing upwards along the direction of the slits (Fig. 5).
