Is Dark Energy the Only Solution to the Apparent Acceleration of the Present Universe?

概要

• 論文の詳細を見る

• 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 ≲ z < 1.7 may confirm or refute this possibility.
