Whenever I see pictures of Quasars and the like, I wonder "Why can we see the streams of energy"? When photons are pouring out of a stellar object, but aren't heading towards us, why can we see them? What causes the photons (or whatever) to head in our direction when all the others are heading somewhere else?
