Or, more precisely, astronomers have used multiple methods of estimating the Hubble constant, and the different methods are converging quite tightly on two different values! This clearly can’t ...

Edwin Powell Hubble is renowned for determining that there are other galaxies in the Universe beyond the Milky Way, and for observing that the universe is expanding at a constant rate. Hubble was ...

They arrived at a value for the Hubble constant of 76.5 kilometers per second per megaparsec, which essentially means that the local universe is expanding 76.5 kilometers per second faster every 3 ...
