Not quite right rudeboy. It depends at what distance the stars light was blocked. the closest star to earth is proxima centauri 4.6 light years away. If blocked at it's source we on earth would find out in 4.6 years, as light travels 1 light year in a year (this is where the measurement comes from).
If the starlight was blocked at a distance the same as the very edge of our solar system we woulf find out in a year or so, at the same distance as the sun we would find out in eight minutes, at the same distance as the moon in a matter of seconds.
If the stars are getting destroyed we would have to wait a lot longer than we would if they were getting blocked.
But then when has science ever got in rtd's way when he's writing a story.
