Researchers have calculated one of the most precise estimates for the expansion rate of the universe today, and it turns out we still have a massive problem. This new value continues to strengthen the dilemma known as the Hubble tension . Different methods have produced distinct numbers for this one single value, and we just got a new one!

The universe is believed to be experiencing an accelerating expansion. The expansion rate, also known as the Hubble constant, can be obtained in multiple ways. One way is from the cosmic microwave background (CMB), the first light that moved freely in the cosmos. Another way is to measure the distance of galaxies and how quickly they appear to reced
