Are space and time fundamental?
Of all the mysteries of life and the universe, none resist the sleuthing of science’s best private eyes more obstinately than the ultimate nature of space and time.
Every several centuries or so, profound insights do occur, immortalizing the names of the investigators who achieved them: Euclid (who cataloged the insights preceding him), Galileo, Newton, Einstein. Yet each advance left deeper questions unanswered. And now the 21st century’s best brains still cannot say for sure whether space and time are fundamental building blocks of natural existence, or are themselves built from more primordial ingredients, so far unperceived.
