Abstract

Two possible explanations for the type SNe Ia supernovae observations are a nonlinearly, underdense void embedded in a matter-dominated Einstein-de Sitter spacetime or dark energy in the $Łambda$CDM model. Both of these alternatives are faced with Copernican fine-tuning problems. A case is made for the void scenario that avoids introducing undetected dark energy.
