The scale of everything (very cool)

When I first saw this link, I thought it was going to be the old(ish) animation that takes you from far out space to the earth and on to the micro scale.  Instead, it is user controllable view of the scale of things, from the smallest to largest known. The smallest and the largest items depicted are theoretical only, but the sizes of most of the items in between are established. In the grand scheme of things, human beings fall approximately in the middle.  On the small end, you have the Planck Length, quantum foam, and strings, which are measured in ~10-9 yoctometers (<10-35) .  On the top end, you have the observable universe and the estimated size of the whole universe. This is over yottameter-scale (1024) at ~1026.7meters. These distances eat gigaparsecs for lunch.

(I posted quickly and may be off by a factor of 10 here or there.  I haven't though much about numbers this small or large.  My intent was to get you interested in clicking on the link!)
