[ExI] DARPA researchers accidently create nanoscale warp bubble using Casimir force

I haven't had time to properly read this yet because I am rushing out  
the door to work, but I damn near spit out my morning coffee when I  
read this. :)

Abstract
While conducting analysis related to a DARPA-funded project to  
evaluate possible structure of the energy density present in a Casimir  
cavity as predicted by the dynamic vacuum model, a micro/nano-scale  
structure has been discovered that predicts negative energy density  
distribution that closely matches requirements for the Alcubierre  
metric. The simplest notional geometry being analyzed as part of the  
DARPA-funded work consists of a standard parallel plate Casimir cavity  
equipped with pillars arrayed along the cavity mid-plane with the  
purpose of detecting a transient electric field arising from vacuum  
polarization conjectured to occur along the midplane of the cavity. An  
analytic technique called worldline numerics was adapted to  
numerically assess vacuum response to the custom Casimir cavity, and  
these numerical analysis results were observed to be qualitatively  
quite similar to a two-dimensional representation of energy density  
requirements for the Alcubierre warp metric. Subsequently, a toy model  
consisting of a 1 m diameter sphere centrally located in a 4 m  
diameter cylinder was analyzed to show a three-dimensional Casimir  
energy density that correlates well with the Alcubierre warp metric  
requirements. This qualitative correlation would suggest that  
chip-scale experiments might be explored to attempt to measure tiny  
signatures illustrative of the presence of the conjectured phenomenon:  
a real, albeit humble, warp bubble.
