As I understand it NASA is using a toroidal capacitor to generate a warp bubble. I know that a capacitor is used to store electric charge. How does this warp space-time?
Do the electrical conductive plates of the capactior need to be really close - less the width of a human hair. With such small distances does the Casimir effect work here to create an area of less density between the plates then the density of space surrounding the capacitor? Is this what they mean by negative energy? At any rate I still don't understand how this can create a warp bubble.
