A cooled hollow superconductive shield is energized by an electromagnetic field resulting in the quantized vortices of lattice ions projecting a gravitomagnetic field
that forms a spacetime curvature anomaly outside the space vehicle.
The Wallace Inventions, Spin Aligned Nuclei, the Gravitomagnetic Field
, and the Tampere 'Gravity-Shielding' Experiment: Is there a Connection?
Just as a moving electrical charge creates a magnetic field, so a moving mass generates a gravitomagnetic field.
According to the ESA, this anomaly could be explained by the appearance of a gravitomagnetic field in the spinning superconductor.
It's the gravitomagnetic field
that causes frame dragging, Nordtvedt says.
Just as a moving electric charge generates a magnetic field in addition to the electric field already present, the Earth's motion ought to generate a completely new kind of field -- a gravitomagnetic field
-- different from the ordinary gravitational field surrounding a body.
