The Local Universe's Expansion Rate Clearer Than Ever. But Still Doesn't Add Up
- nobody9999 6mo agoFrom TFA[0]: A new synthesis of astronomical measurements confirms a persistent mismatch that could point to physics beyond current models Also from TFA: Astronomers have sought to measure the expansion rate of the Universe using two fundamentally different approaches. One method relies on measuring distances to stars and galaxies in the nearby Universe. The other uses measurements of the cosmic microwave background to predict what the expansion rate would be today under the standard model of cosmology.
