Hubbles law

    Cards (4)

    • Hubbles law states that the redshift of a galaxy is directly proportional to its distance from us, therefore the further away a galaxy is, the faster it is moving away
    • v = Ho x d
      v = recessional velocity
      d = distance
      Ho = Hubble constant
    • Hubbles law allows us to estimate the age of the universe
    • hubbles law implies that the space between objects increases space is expanding
