New evidence shows that the key assumption made in the discovery of dark energy is in error Figure 1. Luminosity evolution mimicking dark energy in supernova (SN) cosmology. The Hubble residual is the difference in SN luminosity with respect to the cosmological model without dark energy (the black dotted line). The cyan circles are the binned SN data from Betoule et al. (2014). The red line is the

"They find a significant correlation between SN luminosity and stellar population age at a 99.5 percent confidence level." "When the luminosity evolution of SN is properly taken into account, the team found that the evidence for the existence of dark energy simply goes away"

ダークエネルギーが存在するのではなく、Ia型超新星の明るさが時代とともに変化してきたことを示す観測結果が得られた、と。なんで変化してきたんだろう
