Some stars that you cannot see now do effect us(or rather will effect us). Suppose there is a star that is 10,000 light years away but fired up it fusion furnance 5000 years ago. We won't see that star's birth for another 5000 years but we will see it. Its not fair to say that all stars which are invisable to us today are inconsequential to us. The stars which are inconsequential to us are the ones which are expanding away from us at speed which exceed light....those are the ones I am referring too.
Now in the senario you presented above none of that information would ever be conveyed to us. We could not detect a change of a star visable to us because a star invisable suddenly disappeared. If we could then information would have to travel faster than light thru space which violates SR.
I'm sure Max will correct me if I am wrong.
