At lightning speed
Meaning

Origin
Lightning has always been humanity's most striking example of raw, instantaneous power and blinding speed. From ancient times, cultures worldwide observed the sudden, split-second flash across the sky, a phenomenon that occurs so rapidly it seems to transcend time itself. It's no wonder, then, that this breathtaking natural spectacle became the ultimate benchmark for describing anything incredibly swift or instantaneous. The phrase "at lightning speed" simply captures this primal awe, harnessing the visual and temporal impact of a lightning strike to vividly communicate unparalleled quickness in action or thought, turning a fleeting moment of nature into a timeless metaphor for velocity.
