Navigating This Site

To continue your inward journey to the quarks which make up all matter, use the down buttons or click within the small inner square. At each step, the previous inner square expands to fill the entire image. Increasing detail is provided while the area viewed is one hundred times smaller and the volume is one thousand times smaller than the preceding power of ten. You can change the direction of your journey at any time by selecting one of the up buttons or clicking anywhere within the full image (except the small central square). Remember that there are two separate paths, so if you want to reread a page you just left, use your browser's Back button. You can use the index to jump to any specific power of ten. Enjoy your trip!
