Is dark energy the only solution to the apparent acceleration of the present universe?

Astrophysics 2009-11-07 v2 General Relativity and Quantum Cosmology High Energy Physics - Phenomenology

Abstract

Even for the observed luminosity distance D_L(z), which suggests the existence of dark energy, we show that an inhomogeneous dust universe solution without dark energy is possible in general. Future observation of D_L(z) for 1 \lesssim z < 1.7 may confirm or refute this possibility.
