I used Chrome and it worked perfectly, allow a little time for it to load.

The Scale of the Universe - Interactive
Flash Animation Credit & Copyright: Cary & Michael Huang (http://htwins.net/)Explanation: What does the universe look like on small scales? On large scales? Humanity (http://apod.nasa.gov/apod/ap100725.html) is discovering that the universe is a very different place on every proportion that has been explored. For example, so far as we know, every tiny proton is exactly the same (http://en.wikipedia.org/wiki/Identical_particles), but every huge galaxy (http://apod.nasa.gov/apod/ap120107.html) is different. On more familiar scales, a small glass table top to a human is a vast plane (http://en.wikipedia.org/wiki/Fantastic_Voyage) of strange smoothness to a dust mite (http://www.youtube.com/watch?v=47CIdUld8eQ) -- possibly speckled (http://www.wisegeek.com/where-does-dust-come-from.htm) with cell boulders. Not all scale lengths are well explored (http://www.youtube.com/watch?v=4PKjF7OumYo) -- what happens to the smallest mist droplets you sneeze, for example, is a topic of active research -- and possibly useful to know to help stop the spread (http://en.wikipedia.org/wiki/Airborne_disease) of disease. The above interactive flash animation (http://htwins.net/scale2/), a modern version of the classic video Powers of Ten (http://apod.nasa.gov/apod/ap110201.html), is a new window to many of the known scales (http://apod.nasa.gov/apod/ap100120.html) of our universe. By moving the scroll bar across the bottom, you can explore a diversity of sizes (http://www.kruger-2-kalahari.com/images/the-long-the-tall-and-the-short-21373953.jpg), while clicking on different items will bring up descriptive information.

That was fun, from quantum foam to the observable universe. Quite an eye full!
