Historically, the Hubble constant was introduced by Edwin Hubble in 1929, marking a major breakthrough in our understanding of the expanding Universe. Since then, refining its value has become a ...

Even then, she predicted an end to Hubble's voltage. Now the discrepancy is also somewhat greater for her. The Hubble constant (H 0) is a fundamental quantity in cosmology.

In the new study, Riess's team measures the Hubble constant to a value of 74.03 kilometers per second per megaparsec, give or take 1.42.
