Scientists aim to build the first graviton detector to explore gravity's quantum nature, despite significant challenges.

Researchers at Stevens Institute of Technology and Yale University are initiating a first-of-its-kind experiment designed to detect gravitons, the hypothesized quantum building blocks of gravity.

Physicists are preparing an experiment that sounds like science fiction: a device designed to snare individual particles of gravity and hold them long enough to study. If it works, this “graviton trap ...
