false 4038810 1 Prior to Hubble, the universe was known to consist solely of the stars in the Milky Way and believed to be relatively stable in size. But because of Hubble's discoveries, we now know that the universe consists of an unimaginably large number of galaxies (containing Carl Sagan's beloved "billions and billions . . ." of stars) and that this unimaginably large universe is continually expanding. In this first serious biography of Hubble, Christianson deals both with the enormous importance of these discoveries and, paradoxically, the apparent unimaginably small-spirited and petty nature of the man himself.
