These images are taken from a film called "Powers of Ten" which was made in 1977 by Charles and Ray Eames. The film teaches us about scale and  the relationship between all things big and small. Every time you add a zero  to a number it becomes ten times greater, or a new power of ten. This is shown by the exponent, or the small number to the right of each "10". The  film starts with a sleeping man at a picnic and every ten seconds, the  camera moves ten times further away, measured in meters. When we get to the  edge of the known universe (10 +25), the journey reverses and we get ten times closer with each image. We enter the sleeping man's hand and go deeper and deeper until we finally reach the level of a quark(10-18). Click on  any picture below to learn more about that power of ten.
