Powers of 10 images for demonstrating size relationshipsThis site contains a series of drawings and pictures illustrating a universe that is currently estimated to be 13.7 billion years old, at least 1026 meters in diameter, and made up of quarks and electrons that are known to be smaller than 10-16 meters. Each successive image shows a view ten times wider or narrower than its neighbor. In either direction, new information is presented at each step: Outward, the view widens, showing 10 times the heighth, width, and depth of the previous image; inward, a closeup of the center of an image expands to allow the resolution of more detail. This relationship is emphasized in each picture by outlining a small central square whose edges are one-tenth the size of the whole frame.
