"So far, we’re seeing basic agreement with our best model of the universe, but we’re also seeing some potentially interesting differences that could indicate that dark energy is evolving with time. Those may or may not go away with more data, so we’re excited to start analyzing our three-year dataset soon."

"With measurement errors negated, what remains is the real and exciting possibility we have misunderstood the universe"

#i have to include the spectroscopic pov rather than just leave the photometric one hanging around #photometric redshift is terrible compared to spectroscopy due to its high level of uncertainty #and desi (dark energy spectroscopic instrument) just announced their cosmology results this week too #they deserve a mention #yes both find that the is maybe a degree of contention about the hubble constant (and whether it is truly constant)#but i would put far more faith into spectroscopic readings for high redshift science where redshift becomes equivalent to distance #space #science #cosmology
