Atom Optics to Detect the Imperceptible

A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible: gravitational waves or ripples in space-time caused by cataclysmic events including even the Big Bang itself.

This is a close-up view of the "spectrometer-on-a-chip" technology that could dramatically reduce the size of spectrometers in the future. (Credit: NASA Goddard/Chris Gunn)
