inverse-square law of the gravity in nano-meter scale via neutron scattering tagged posts

Principle of the experimental test of the inverse-square law of the gravity in nano-meter scale via neutron scattering. Deviation from the inverse-square law will be observed as the modification in the angular distribution of the scattered neutrons. Credit: The NOP collaboration

Scientists use high-sensitivity experiments to probe exotic gravitational force. Scientists have used a pulsed slow neutron beamline to probe the deviation of the inverse square law of gravity below the wavelength of 0.1 nm. The experiment achieved the highest sensitivity for a neutron experiment demonstrated to date, and is a significant step toward determining whether the space we live in is really limited to the 3 dimensions most are familiar with.

Often, practical limits control the experimental measurements th...
