Figure 5 represents one version of this effect/ where the vehicle and its contents would
be located at the steep gradient and therefore would jointly experience acceleration
forces. Taken directly from the Frontiers book, this image represents what would
happen if it were possible to asymmetrically modify Newton's gravitational constant to
induce gravitational gradients that would then, in turn, accelerate the vehicle. Despite
the similarity to the distortions in the warp drive (Figure 4), these surfaces represent
scalar potentials of gravitational fields. Figure 6 is a modified version of this where the
double-hull configuration of Figure 3 is imposed, along with the condition that the inner
region remains unaffected. In Figure 6, the locations of the inner and outer shell are
identified on the figure. The notion of the gravitational bias drive has been modified
here to illustrate the concept of having two separate zones of inertial and gravitational
forces.
In this case, the plotted surface represents a scalar potential of an inertial
frame, where a gradient has the same effect as a gravitational field. The smaller central
flat area is the inside of the vehicle where no acceleration forces are felt. The outer
edges of the diagram are also flat, representing the unaffected space sufficiently far
from the propulsive effect. The distorted regions in between represent the effects of
both the outer and inner hull shells. The outer hull shell induces a gradient that propels
the vehicle, and the inner shell acts to prevent those distortions from reaching the crew
cabin.
It should be emphasized that these notions are at the level of thought
experiments, as opposed to being mature theory.

Figure 5. Hypothetical Gravitational Bias Drive.
In short, this Inertial Frame Bias Drive has affected the space both outside and inside of
the craft to propel the vehicle and to keep its crew isolated from the resulting
acceleration forces. For example, if the outer hull creates a 10-g field outside the craft,
the inner hull would compensate to create an opposing field such that the crew cabin is
free of the 10-g acceleration forces. It can, therefore, be speculated that-if such field­
affecting physics is discovered-the inner shell could create a 1-g field when the craft is
coasting in 0-g deep space.
