Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but with more precise data has come a conundrum: Estimates based on measurements within our local universe don’t agree with extrapolations from the era shortly after the Big Bang 13.8 billion years ago.
A new estimate of the local expansion ratethe Hubble constant, or H0 (H-naught)reinforces that discrepancy.
Using a relatively new and potentially more precise technique for measuring cosmic distances, which…
