, 02:37, January 31, 2012→39 billion light years away?
::::::::::::::::So an object at x light years most probably was closer at an earlier time? [[User:RobSmith|Rob Smith]] 21:31, 30 January 2012 (EST)

:::::::::::::::::No, that depends on gravitational binding. Space isn't expanding between gravitationally bound objects. --[[User:GeorgeLi|GeorgeLi]] 21:32, 30 January 2012 (EST)

::::::::::::::::::That's not a flat no, and that's why I asked "most probably"; some objects may be drifting further away with an expanding universe? [[User:RobSmith|Rob Smith]] 21:37, 30 January 2012 (EST)
::::::::::Rachel, Aschalfly says that he saw "numerous references" to people talking about observable stars 39 billion light years away. I have an open mind, and want to be able to have him share his knowledge with me. [[User:ScottDG|ScottDG]] [[User talk:ScottDG|Talk]] <b>Is Gingrich an orphan? Conservapedia says yes.

:::::::::::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.
