Deep Thought — (a possible sci fi movie?)

You know, the earth is only so big – but there is sunshine landing on oodles of nothing out there.  Is the sun burning itself to extinction – the very definition of futility? Is earth the only place that uses the light as opportunity for life? What happens to all the sunshine, the huge gigantic arc of light that hits the not-earth area?  Does the sun have an exitential crisis about its own utility?  Where does all that other light go? What does it illuminate and warm and fuel?

Science Fiction Storyline:

What if, we surrounded the sun in a gigantic solar blanket just outside our widest trajectory to capture energy.  We’d be capturing all the light, not just what hits earth.  That would cause the aliens dependent on that light we think is surplus to come and attack the blanket.   A good way to find out if anyone else is using the sunlight that misses earth, or to kill them off completely by depriving them access.  Let me know if this film already exists.  I could use a little humorous perspective on my own idea of utilitarianism.
