Talk:Starlight problem (view source)
Revision as of 02:22, January 31, 2012
, 02:22, January 31, 2012→39 billion light years away?
:::::::::::There most certainly are stars 39 billion light years away, or close to it. That's the cosmological principle in action. But, as Aschlafly pointed out, they're not going to be observable because light from those stars has not had time to get to us, and if we attempted to look back that far, we will eventually hit the "wall," so to speak, as a result of the opacity of the early universe.

::::::::::::I don't doubt there are stars that far away. I am interested in the people that have ''observed'' them, which Aschlafly has numerous references to. [[User:ScottDG|ScottDG]] [[User talk:ScottDG|Talk]] <b>2 billion lightyears ago...wait, what? </b> 21:12, 30 January 2012 (EST)

:::::::::::::Nobody's observed them. The most distant object anyone has ever observed is the galaxy UDFj-39546284, which - if it still exists, which is unlikely - is 31.7 billion light years away and is now way outside the observable universe. The light from it has travelled 13.2 billion light years to get to us. --[[User:GeorgeLi|GeorgeLi]] 21:22, 30 January 2012 (EST)
