Near zero, a frontier of physics

Abstract

By reducing several of the variables of physics, such as temperature, electric field, magnetic field, gravitational field, and electric charge, very nearly to zero, new regions of physics can be explored. This makes possible the investigation of many fundamental problems in physics such as the dragging of inertial frames in general relativity; the search for gravitational waves from collapsing stars; the search for fraction electric charge on matter; the search for monopoles; the force of gravity on electrons and positrons; the electric dipole moment on 3 He; the equivalence principle; a more accurate determination of the λ transition in zero gravitational field; the search for a new gravitational particle by checking the inverse square law of gravity; and the measurement of fundamental constants h/m , α.
