the.com/motion
the universe's refusal to sit still, scaled from atoms to galaxies fleeing each other
means The act, process, or state of changing position or moving — anything from a wave of the hand to the drift of continents.
from From Latin 'motio,' meaning a moving or motion, built on 'movere,' 'to move' — the same root that powers 'move,' 'motor,' 'mobile,' and 'momentum.' It reached English through Old French 'motion' in the late Middle Ages. That busy little 'movere' is one of Latin's great verbs, spinning off a whole family of words about getting things to go.
