Via Mohammed A. Attia, Faculty of Informatics, The University of Manchester.

Universcale is a cool Nikon web app. Based on a scale ranging from the unmeasurable world of femtometres (1 quadrillionth of a metre) to the largest size we can measure (13.7 light years, the size of the universe), it enables us to look at the sizes of things, from galaxies to items of daily life to atomic particles. The entire universe is put into into proportion, and we are able to view from a single perspective selected entities living in it. Being set up against a scale allows to comparatively grasp their size and fathom their and our place within this world of measurement.

All the items mentioned on that scale live on sections that are based on the measurement we like to apply to them, e.g. light years, kilometers, centimeters or femtometres - all up 9 segments. They have names like the mysterious “The Great Primordial” of femtometres, the factual “Limits of the Naked Eye” of nanometres, the almost poetic “A Realistic Grandeur” of kilometres or the descriptive “The extremities of Space” for the largest macro scale we know. And the experience is not just graphical - all segments and elements relating to the scale are explained when clicking on them.

It really is quite amazing to zoom all the way out into stars and galaxies, starting from small atomic particles, and realising that every time you go a magnitude higher, everything you saw before, from the flea to Mount Everest, is contained in this tiny little grid in the lower-left side of the screen.

Crave believes that the “Carl Sagan should be narrating this” planetarium music helps; I’m not so sure because it stopped when I started clicking on things. But that’s not really a downer. As Will Greenwald says on Crave: “If you have a few minutes and want to feel really, really small (or really, really large, or really, really disoriented), check out Universcale. It will eat up your afternoon and enlighten you as to the true size and scope of the cosmos. Not bad for a Flash app.”
