This award-winning video sends you on a fascinating excursion to the ends of the universe to gain a better understanding of the concept of orders of magnitude.
Your adventure begins at a picnic. Every ten seconds, you view this starting point from ten times farther out, until our own galaxy is visible only as a speck of light among the multitude of other galaxies. Returning to Earth at breathtaking speed, you zoom in on a human hand, steadily increasing magnification until you find yourself inside a proton of a carbon atom within the DNA molecule of a white blood cell.
