Mechanism of Gravity Impulse
It is well-known that energy-momentum is the source of gravitational field.
For a long time, it is generally believed that only stars with huge masses can
generate strong gravitational field. Based on the unified theory of
gravitational interactions and electromagnetic interactions, a new mechanism of
the generation of gravitational field is studied. According to this mechanism,
in some special conditions, electromagnetic energy can be directly converted
into gravitational energy, and strong gravitational field can be generated
without massive stars. Gravity impulse found in experiments is generated by
this mechanism.Comment: 10 page
Gravitational Shielding Effects in Gauge Theory of Gravity
In 1992, E.E.Podkletnov and R.Nieminen find that, under certain conditions,
ceramic superconductor with composite structure has revealed 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.Comment: 13 pages, no figur
