Gravitationally Squeezed Vacuum for Wormholes
Traversable wormholes require negative energy density, which can be generated through 'gravitationally squeezed vacuum states' created by the interaction of ordinary matter and gravity, as described in quantum optics.
Negative Energy via Parabolic Mirrors
Using parabolic cylindrical mirrors to reflect quantum vacuum fluctuations onto a focal line, creating a region of negative energy density surrounded by positive energy.
Negative Mass Engineering Application
