Double Hubble

  1. Feb 13, 2004 #1
    When the age of the universe is estimated via Hubble's Law (v = Hr), the photons that are received were emitted from sources that are now further away - so in the limit of the theory, H = c/R where R is the Hubble scale factor or Hubble Radius at the time the photon was emitted. Closeby galaxies are not much further away now because light from them has not been traveling nearly as long as the light presently being received from the more distant sources - query - are the data from distant sources corrected to reflect the current size of the universe? This effect would appear to cause a non-linear distribution of galaxies (higher galactic density at greater distances).
