Abstract: | In 1992, E.E. Podkletnov and R. Nieminen found
that under certain conditions, ceramic superconductor with
composite structure reveals weak shielding properties against
gravitational force. In classical Newton's theory of gravity and
even in Einstein's general theory of gravity, there are no grounds
of gravitational shielding effects. But in quantum gauge theory of
gravity, the gravitational shielding effects can be explained in a
simple and natural way. In quantum gauge theory of gravity,
gravitational gauge interactions of complex scalar field can be
formulated based on gauge principle. After spontaneous symmetry
breaking, if the vacuum of the complex scalar field is not stable
and uniform, there will be a mass term of gravitational gauge
field. When gravitational gauge field propagates in this unstable
vacuum of the complex scalar field, it will decays exponentially,
which is the nature of gravitational shielding effects. The
mechanism of gravitational shielding effects is studied in this
paper, and some main properties of gravitational shielding effects
are discussed. |
