Behold this mind-blowing, interactive animation which will take you on a journey from the smallest to the largest known scales in the universe. From quantum mechanics to cosmology, the size scales span an incredible 60+ orders of magnitude - which means the largest known "things" are more than a million million million million million million million million million million (whew!) times bigger than the smallest known things!

It's a very polished animation which, rather impressively, was produced over the course of 18 months by two 14 year-old wizzkids (who were inspired by their seventh grade teacher showing them a video of the size of cells)! Wow on every level!
