Nano-constraints on the spatial anisotropy of the Gravitational Constant
C. S. Unnikrishnan, G. T. Gillies
Abstract
We present constraints from various experimental data that limit any spatial anisotropy of the Gravitational constant to less than a part per billion or even smaller. This rules out with a wide margin the recently reported claim of a spatial anisotropy of G with a diurnal temporal signature.
