Specifically, the endpoint of significant note is that the inviscid fluid medium described, from MacCullagh and Maxwell up through Kevlin to the Cosserats, has most of the properties now known as a superfluid. The exploration of superfluid models of spacetime is not a new concept with some of the first major papers published circa 1976, but the Cosserat model of precisely how a superfluid vacuum might work is significantly different from any previous proposals with numerous implications for the application and interpretation of Lorentz invariance as well as expectations about the phenomena of vortex filaments proposed in those earlier theories and now shown to exist within experiments with superfluid helium.
