Exploring the quantum nature of gravity requires systems that balance quantum control and gravitational interaction, most plausibly within the microgram-to-milligram mass range. Here, the authors ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...
