PhysicsThe quantum experiment that could prove reality doesn't exist We like to think that things are there even when we aren't looking at them. But that belief might soon be overturned thanks to a new test designed to tell us if quantum weirdness persists in macroscopic objects Features
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 51¶¯Âþ
