SpaceQuantum nature of gravity may be detectable with gravitational waves Perhaps the most important problem in physics is how gravity and quantum mechanics fit together, and strange fluctuations in gravitational waves could help us figure it out News
PhysicsWhy is it so difficult to find a viable quantum theory of gravity? The way we calculate the properties of subatomic particles with quantum theory goes haywire when it comes to hypothetical particles of gravity, but there may be a clever workaround Features
