This comes from a discussion forum, where a friend of mine asked the following:
We can see objects in space billion of light years away, right? I started wondering about that.
If you take 2 objects in space, the other should be able to see the other no matter what angle in degrees you position it at. That would almost seem to imply that light is being sent out in an infinite number of degrees/angles from the source. But that cannot be true because energy cannot be infinite.
If the observer goes out far enough from the source, would there be gaps in the light? Could you pick a viewing angular degree (of extremely high angular precision) where there's no light?
I'm actually quite curious about this question myself and really have no answer, and the discussion hasn't really yielded a satisfying answer. So I figured I would bring it here on behalf of my friend and to sate my own curiosity.
