Shear-dependent Pressure in a Lema\itre-Tolman-Bondi Metric
Abstract
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 pDE=(w0+ε w1)DE where ε is the ratio of LTB shear to LTB expansion.
