Calculations based on the observed brightness of [[supernova]]e of known energy output can determine the distance to more distant objects.  The most distant object known is a galaxy cluster is estimated to be approximately thirteen billion light-years away from Earth, observed by the [[Hubble Telescope]] using gravitational lensing.<ref>Amos, 2004</ref>

==Starlight Problem for the Big Bang Theory==

==Horizon Problem for the Big Bang Theory==

Although [[atheist]]s simplistically use the starlight problem to argue against a  young Earth, the [[Big Bang theory]] has had difficulty in explaining its own light travel problem, known as the [[horizon problem]].
