In this poster we present the neutron as a measuring tool and as an object for gravity research. It provides access to all parameters: distance, mass, curvature, energy-momentum tensor and torsion. We show that Gravity-Resonance-Spectroscopy, a new method developed for that purpose, allows to test Newton's inverse square law and to search for dark matter and dark energy candidates. It is also possible to probe neutron's electric neutrality. We use a method based on spectroscopy, as frequency measurements have shown spectacular sensitivity in the past.
