Sizes

Donno what it's called, but this is very cool, intriguing, and fun.

Each circle on the screen is larger or smaller than the next by a factor of a thousand  or 3 orders of magnitude. The ends, I think, are somewhat (maybe very) speculative. And notice the huge distance between the small end and the nearest theoretical structure. I liked especially to see the range of cells, and then of suns.
