Pacing Earth's history using galactic orbits.
Earth has circled the galaxy 18 times. The dinosaurs died

Early ('97?) notes ripped from above...
Either notable objects, merely ordered:
universe, galaxy, solar system, sun, planets, mountain, you, insects,
microbes, proteins, molecules.
or labeling even magnitude steps (this is mass, with steps of 1010 kg):
universe, galaxy, sun, moon, mountain, you, tiny bug, piece of cell, atom, light.
or clumped in magnitude steps:
universe
moon, sun, galaxy
knat, you, mountain
piece of cell, atom, light
or...
