Explanation: What does the universe look like on small scales? On large
scales? Humanity 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, but every huge galaxy
is different. On more familiar scales, a small glass table top to a
human is a vast plane of strange smoothness to a dust mite -- possibly
speckled with cell boulders. Not all scale lengths are well explored --
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 of disease. The above interactive flash animation, a modern
version of the classic video Powers of Ten, is a new window to many of
the known scales of our universe. By moving the scroll bar across the
bottom, you can explore a diversity of sizes, while clicking on
different items will bring up descriptive information.
