Explanation: What does the universe look like on small scales?
On large scales?
Humanity is discovering that the universe is a very different place on every proportion that has been explored.
Not all scale lengths are well explored -- what happens to the smallest mist droplets you sneeze, for example, is a topic of active research -- and possibly useful to know to help stop the spread of disease.
By moving the scroll bar across the bottom, you can explore a diversity of sizes, while clicking on different items will bring up descriptive information.
Janill, this really showcases how vast in both directions our scale is.
It makes me feel both very big and very small. And very humbled.
