Testing gravity's quantum nature

Abstract

The Physicists proposal of an experiment to test whether gravity is quantum or not, thereby settling questions about the force's true nature is discussed. Among them includes Sougato Bose of University College London and his colleagues who proposes an experiment that starts with a neutral mass of about 10-14 kilograms containing material with a property called spin, which can be up or down, as the mass falls through a continuously varying magnetic field that affects its path. To test the quantum nature of gravity, two masses would be dropped to see if their spin components are entangled once the masses are back to their original state which could tell if gravity is indeed a quantum force.
