abstract
An exact, plane wave solution of the gravitational field equations is investigated. The source stress tensor is represented by an anisotropic null fluid with energy flux to which the energy density $\rho$ and all pressures are finite throughout the spacetime. They depend on a constant length (taken of the order of the Planck length) and acquire Planck values close to the null surface $t - z = 0$, the $z$-axis being the direction of propagation. The timelike geodesics of a test particle are contained in a plane whose normal has constant direction and the null trajectories are comoving with a plane of fixed direction.

Accelerating imperfect fluid
An acoustic-type metric with a spatially varying velocity field yields an imperfect fluid with zero isotropic density, nonzero anisotropic pressure, and a Yukawa-like potential that leads to rapidly damped geodesics.
