Your deleting of what I post is really irritating.


I see no point in repeating material that's already clearly displayed and not needed.


Not the slightest hint of this so far, and not likely to occur in the future due to vast distances.

The vast distances can be crossed by radio waves.


Not in any reasonable time, practical for 2 way communications.

It still comes down to : Distance = Speed x Time .

What part of this don't you understand ? !
