The Scale of the Universe: Interactive
This is very cool! The title link is a permanent link to today's Astronomy Picture of the Day, one of my all-time favorite websites. It interactively displays a continuum from 10-35 meters (0.00000000001 yactometers)—the [theoretical] size of a single string or of the spactime or quantum foam—to 9.3×1028 meters (93 billion light-years)—the size of the observible universe. How is it that we can see 46½ billion light-years away when the Universe itself is only 13.7 billion years old? The answer is embedded in the Flash linked to in the title.
