Quantum Gravity in Particle Colliders

We are like a factor of a trillion away from being able to test quantum gravity in particle colliders. So really nowhere in the near future will particle colliders be able to answer this question. Well, I think part of what we're going to be talking about here today are experiments that have kind of ideas about how to test this without destroying the solar system. And they involve diamonds and lasers and space lasers. No tabletop lasers in space. No, no tabletop lasers in Pasadena. Oh, that take up space in Pasadena. A table near you. All right. If it's dig into it, Daniel, what is the first of these experiments?
