In a previous post we highlighted a brilliant flash animation from Learn.Genetics to show the scale of living cells to atoms. Now a similar animation goes much further, allowing you explore the entire scale of the universe, using a simple scroll bar. As a teaching tool it's perfect for introducing DNA, exploring the atom, sub-atomic particles, wavelenthgs of light, comparing planet or star size in astronomy or simply just for fun. It's "fascinating for any biologist, chemist, physicist, astronomer, cosmologist, science student or simply anyone who marvels at our insignificance in the grand scale of things".
