In the standard Big Bang model, the universe expands according to the Hubble law, a simple relation expressed as v=Hod, where v is the velocity of a galaxy at a distance d, and Ho is t...
Is the Hubble Constant in the Neighborhood of 100 Km/S/Mpc?
Viewpoint: Yes, observations have raised the estimate of the Hubble constant from 50 to near 100 km/s/Mpc.
Viewpoint: No, the best observati...
The Hubble constant is used in astrophysics to characterize the expansion of the universe. The constant specifically relates the distance to a galaxy to that galaxyüs velocity of rece...
