Is the Standard Model Wrong About the Hubble Constant?
One of the great mysteries in science today is understanding the expansion of the Universe. The numbers we see aren’t the ones we expected, and it just happened again.
Understanding the Hubble constant, the rate at which the Universe expands, is one of the crucial figures astrophysics need to better understand the Cosmos. There are several ways to measure this rate, but each measurement produces significantly different results, forming one of the great mysteries of modern astronomy.
