I wonder if some old stars will become invisible to our eyes after a while because of the redshift?
Since they get further away from earth, maybe we won't receive their radiation in visible light any more?
I'm talking about stars that are not obscured by any other objects or dust, which you don't have to detect them in infrared (IR).
If the answer is yes, then how long will it take for a star to be obscured to us because of the redshift? Say a star that is 5 billion years from us and getting further away each day.
thanks
