Query: Swimming and swirling colorful ghosts   We show that the ideal fluid limit, defined as the existance of a flow frame
$u_\mu$ with respect to which the fluid is homogeneus and isotropic, and the
consequent independence of the equation of state on $u_\mu$, is incompatible
with non-Abelian gauge theory. Instead, the equation of state becomes dependent
on $u_\mu$ via modes which are roughly equivalent to ghost modes in the
hydrodynamic limit. These modes can be physically imagined as a field of
'purcell swimmers' whose 'arms and legs' are outstretched in Gauge space. Also,
vorticity should couple to the Wilson loop via the chromo-electro-magnetic
field tensor, which in this limit is not a 'force' but instead represents the
polarization tensor of the gluons. We show that because of this coupling
vorticity also aquires swirling non-hydrodynamic modes. We then argue that
these swirling and swimming non-hydodynamic modes are the manifestation of
gauge redunancy within local equilibrium, and speculate on their role in
quark-gluon plasma thermalization
