Quantum Experiment Could Finally Reveal The Elusive Gravity Particle
The graviton – a hypothetical particle that carries the force of gravity – has eluded detection for over a century.

I'm curious how the detector would actually work, and also what the result would be in the case where gravity is intrinsically classical.
PBS SpaceTime has a video on that this week: https://www.youtube.com/watch?v=eAtbzhpI4Js
Since it wasn't clear until I started to watch: This talks about the possibility of semiclassical quantum gravity in specific. They also gave a refresher on the basic problem if needed. Very nice!
Unfortunately it looks at a different experiment, though.
