Yet the law that made that revelation possible had been written in 1912 by Henrietta Swan Leavitt at the Harvard College Observatory. Her period-luminosity relation turned stellar rhythm into measurable distance-and distance into cosmic scale.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThe Distance Measurer\u003c\/em\u003e reframes one of the most celebrated episodes in modern science.
