Better Hubble constant measurement
Better Hubble constant measurement
https://www.sciencedaily.com/release...0122171325.htm quote for their research, the scientists chose one specific subset of quasars -- those whose light has been bent by the gravity of an intervening galaxy, which produces two side-by-side images of the quasar on the sky. end quote .... time delay of flicker, gravity... ... Result: 72.5 kilometers per second per megaparsec ... All if lightspeed is constant of course ;-) |
