New measurement of universe's expansion rate is 'stuck in the middle'

Astronomers measured red giant stars to figure out a new measure of how fast the universe is expanding. (Credit: Norval Glover/University of Chicago) If you’re confused by modern cosmology, you’re not alone. Cosmologists themselves are confused, and two new results, using very different methods, add to their collective bewilderment. The results are measurements of how fast the universe is expanding, known as the Hubble constant. In recent years, astronomers keep finding strangely different a
