Dark Energy
15 reportsReporting makes sense of Dark Energy by comparing large-scale structure and cosmological parameters, with separate attention to competing models. Conclusions concerning large-scale structure remain tied to instrument calibration, population statistics, and transparent methods; any broad claim must allow for the fact that selection effects and uncertain source distances can alter inferred rates or energies.
