the universe's way of insisting it's still alive, one beat at a time
means throbbing or beating with a steady, rhythmic motion, like a heartbeat or a flickering light that swells and fades
from From Latin 'pulsus,' meaning a beating or striking — itself from 'pellere,' to drive or push. The same root drives 'pulse,' 'impulse,' and 'propel': all of them a kind of pushing-against. English took the verb 'pulse' and let it pulse on, adding the '-ing' that turns a single beat into an ongoing one.
