Some implications of gravitational superconductivity

We construct a gravitational superconducting model composed of gravitationa l London equations, gravitational Meissner and shielding effects, a gravita tional fluxoid, and oscillation modes of a particle beam in a thin cylindri cal gravitational superconductor. This model is applied to the study of neu tron stars. An experiment to check the gravitational shielding in a terrest rial laboratory using the Supertrons of Matsuzawa is proposed as well.
