> a toy model consisting of a 1µm diameter sphere centrally located in a 4µm 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.
Fascinating.
The poison warp bubble is much cooler and stealthier. And as someone else mentioned, you aren't restricted by the lightcone.
And in case that article is not some pre- 1 April joke: how the heck you all here peoples can be so calm and "meh HFT will eat this" ??????
It should be 1µm and 4µm instead.
