Another relevant calculation regards the local energy density required to generate this
expansion. A similar calculation to the one just performed indicates that the
cosmological constant, an expression which characterizes the energy density of space,
must be increased by a factor of 1052• This implies an energy density of:
(7.5)
This is, indeed, an incredible number. However, the total energy requirement would be
reduced if we assumed a "thin shell" of modified spacetime. Figure 9 illustrates the case
where the warp bubble thickness is reduced. More detailed research is necessary before
we cou ld accurately predict the minimum shell thickness that would be necessary to
support a stable warp field. However, if a shell could be produced that was merely a
single Planck length in thickness, then the energy requirements would be reduced
immensely.

Figure 9. Two Images Illustrating the Contrast Between a Thick (left) and Thin (right) Shell Warp
Bubble. A thin shell warp drive model has the capacity to dramatically reduce the energy requirements of a warp
drive.
Under this new paradigm of warp drive, where the necessary contracting and expansion
of spacetime is generated by a manipulation of the radius of the extra dimension, one
can clearly see that the energy requirements are reduced immensely when compared to
the calculations of Lobo and Visser (Reference 12). Table 3 illustrates the energy
requirements for a range of multiple of the speed of light. All ca lculations are order-of­
magnitude.
