The Scale of the Universe 2 This interactive flash animation was produced in association with NASA (http://apod.nasa.gov) to show the incredible difference in scale between the smallest objects in the universe (1 yoctometre, or 1x10^-27m, the approximate diameter of a neutrino), and some of the largest (for example the largest observed galaxy, with a diameter of approximately 5 million light years, or 5x10^22m). The human brain has not evolved to comprehend sizes at these extremes, and we can really only associate with those that are close to the size of our own bodies and our immediate surroundings.

You need a more recent version of Adobe Flash Player.
