THE SCALE OF THE UNIVERSE

One vital area of science education long lacking is in getting people to understand the true vast scale of the universe in which we live. We humans, with our analog meat brains, often have trouble intuitively visualizing things that are beyond our typical day to day experience. Oh, we can bandy about the numbers and equations for the very large and very small easily enough, but trying to grasp on a visceraal level what those numbers actually mean in the real world can be quite a challenge at times.

If people understood better just how small we and our planet are, and how tiny a sliver of time we've been alive as compared to the lifetime of the universe, that perspective would help to alleviate much of the confusion and ignorance that dominate some aspects of public discourse, such as politics, climate change, evolution, space travel, and more.

This page collects links to various demonstrations of the true scale of existence from various websites, articles, animations, illustrations, and so on. If you know of such link that isn't in the list below but would like to see it included, just contact me at: plucas1@hotmail.com
