The scale of the Universe

The Scale of the Universe is an extremely cool, educational Flash animation from Cary and Mike Huang, showing the relative scale of pretty much everything.

You can zoom in and out in scale through hundreds of objects,  from the tiniest – quantum foam and strings – to the most massive – the universe itself.  Each object is represented by a simple drawing, with it’s size indicated alongside.

Although the idea of showing scale in this way isn’t all that original – the Powers of Ten documentary got there over 40 years ago – the implementation by the Huang Twins is pretty amazing. Especially the smooth as silk, slider operated zoom control.

The page the app is on also includes links to a disorientating Wrong version where objects are mixed up,  and a Swirly version that spins as you zoom in and out.

If you haven’t already, do check it out.
