Very big and very small numbers can be hard to comprehend. Having visualizations and videos, like the one below, can helpful in understanding what all those zeros mean. (Although, it can still be hard to wrap your mind around the scales involved.) This videos zooms out to 1024 meters and then back in to 10-16 meters. This range is smaller than that of of the Scale of the Universe site (1027-10-35 meters) mentioned in my previous post about the very big and the very small, but it was made over 35 years ago.
