Shear-dependent Pressure in a Lema\^itre-Tolman-Bondi Metric
We propose to explain the dimming of distant supernovae as the combined effect of dark energy and a Lema\^itre-Tolman-Bondi (LTB) metric. We take dark energy to have a shear-dependent pressure $p_{DE}=(w_0+\epsilon w_1)\rho_{DE}$ where $\epsilon$ is the ratio of LTB shear to LTB expansion.
