hey buke, try thinking of it like this:
imagine a big bright lightbulb, hanging from the ceiling, with a big, round lampshade around it like a big sphere, so you can't see the light. now drill a kazillion pinprick sized holes in it, all the way around the surface of the sphere. now as you look at the sphere, you see all these points of light, each one unique in that it shines a beam in a different direction. if you didn't know any better, you'd think there were a kazillion separate, unique little lights all individualized and on their own separate journey. in fact, if you were one of these point of light, you might think the same thing.
until you looked inward...

have fun, mark
