Space Telescope Data Reignites Debate Over How Fast Our Universe Is Expanding
"A new front has opened in the longstanding debate over how fast the universe is expanding," writes Science magazine: For years astronomers have argued over a gulf between the expansion rate as measured from galaxies in the local universe and as calculated from studies of the cosmic microwave backg...
But over the past week, results from NASA's new James Webb Space Telescope orbiting observatory suggest the problem may be more mundane: some systematic error in the strategies used to measure the distance to nearby galaxies. Combining all three methods the team derived a value "just shy of 70 km/s per Mpc," according to the article — leading the University of Chicago's Freedman to say "There's something systematic in the measurements. But the controversy continues, according to Adam Riess of Johns Hopkins University (leader of a team of Hubble Constant researchers known as SH0ES).
