In effect the exotic matter that is required for the violation of the weak energy condition is associated with the braid group for a spin field that has a hyperbolic knot topology.

Sarfatti: How can we control the braid group? What does your interesting math mean physically?

Crowell: What does this mean physically? In effect this is a nonlocal effect of the Fermi field. The hyperbolicity of a Fermi field means that the q-wave encompases a vast region of space nonlocally. For the torus topology the field. The twisting of the handle determines the spin statistics globally.

Sarfatti: Do you mean you can get exotic spinor bosons?

Crowell: Indeed the number of hyperbolic knots is infinitely greater than the torus knots. Further, we can think of this handle on the 2-d disk as a Fermi-Dirac particle. In effect matter, as Einstein suspected, is the result of a nontrivial topology on space. Now Fermi fields have a positive vacuum eigenvalue, boson have negative eigenvalues. As a side note the compelling reason for supersymmetry is that if every fermion has a corresponding boson then the vacuum energy is identically zero without normal ordering ambiguities.

Sarfatti: But, in fact, supersymmetry is badly broken. So if you can control the degree of breaking in small regions you can release zero point energy.

Crowell: In effect the matter that generates this effect is ordinary matter that is placed in a configuration that becomes exotic.

Sarfatti: Interesting.

Crowell: The Casimir effect that generates the odd spacetime configuration is then due to the hyperbolic diffeomorphism generated by the spin field with a braid group possessing a negative Gaussian curvature.

Sarfatti: How do we make a device to implement this? How do you use the antimatter?

Crowell: Well as for the engineering, I don't have a precise idea. The antimatter must be used to create the Casimir vacuum. Think of it this way. If you have a region with a lowered vacuum energy then the vacuum outside is going to exert a pressure on the walls. So in order to generate the Casimir vacuum with this negative eigenvalue requires that a force must be exerted on the walls by your engine.

This 1-d picture should get the point. Now to expand the negative energy region you must exert these 2 forces through a distance d, so the total work reguired is W = 2F*d. For an ideal situation the work required should then be equal to, but in opposite sign, to the negative energy contained inside the region. Now in reality our warp drive has to be a sort of refridgerator combined with some kind of electromagnetic device that can then push the cloud outward to create the inner region with a lower energy. Now if one groks on this a while it becomes apparently a very difficult problem; not impossible, but still difficult.

Sarfatti: Fyi just last night before I got this from you I wrote the following to Creon Levit at NASA about a seemingly unrelated application of Bohm pilot-wave theory to quantum chemistry
