the universe's only currency, never spent, just endlessly swapped between forms
means The capacity to do work or cause change — the measurable stuff that powers everything from a lightbulb to a sprint, existing in forms like heat, motion, light, and chemical bonds.
from From Greek 'energeia,' meaning 'activity' or 'operation,' built from 'en-' (in) plus 'ergon' (work) — the same 'ergon' lurking in 'ergonomics' and 'erg.' Aristotle coined 'energeia' as a philosophical term for actuality, being-at-work, as opposed to mere potential. It passed through Late Latin 'energia' and entered English in the early 17th century as 'vigor of expression,' only later being drafted into physics, where the 19th century gave it its precise scientific muscle.
