Hubble's law states that the universe is expanding at a rate that places its age at about 10 to 15 billion years. However, some of the stars in the universe, in particular those found in globular clusters, appear to be older. This paradox has led to debate among astronomers about how old the universe is. In his Perspective, Chaisson argues that such age controversies have occurred in the past and that the paradox will no doubt be resolved, as in the past, as more data comes in and better analyses of the data are carried out.
