Abstract

I consider the relation of explanations for the observed data to testability in the following contexts: observational and experimental detection of dark matter; observational and experimental detection of dark energy or a cosmological constant Λ; observational or experimental testing of the multiverse proposal to explain a small non-zero value of Λ; and observational testing of the possibility of large scale spatial inhomogeneity with zero Λ.
