3D method can accurately measure gravity in wide binary stars, as demonstrated by pilot study

Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of gravity in the low acceleration regime, weaker than about 1 nanometer per second squared.
