DES BAO scale measurement
In gold, we see the Dark Energy Survey BAO scale measurement, which deviates from the standard model (horizontal line at 1 in this plot) by 4%, while the uncertainties associated with the analysis are 2% (indicated by the golden vertical bar). This discrepancy could be a clue about dark energy or a mere statistical fluctuation, with a 5% chance. This measurement has been made by observing galaxies that emitted their light when the Universe, which is 14 billion years old, was about half its present age. In blue are shown measurements from the Baryonic Oscillations Spectroscopic Survey (BOSS) and its extension (eBOSS). DES gives us the most accurate measurement of when the Universe was about 7 billion years old. Image credit: Dark Energy Survey Collaboration.
