The interesting thing is that the vast majority of the universe is in the "everything else" zone.... contemplate that one for a while...
Hmm, I don't think this is correct, depending on what you mean exactly.
When we talk about the universe, we usually mean the observable universe. Since we receive light from all parts of the observable universe (it's observable after all), that means we are in the future light cones of those locations (each roughly an expanding sphere in 3D+time). If we can see something, it can effect us.
But, not all of those places are in our future light cone. Because of the metric expansion of space, which causes accelerated growth of the universe, our sun's light will never reach the outer regions of the observable universe, and we will never be able to travel there unless we find some way around the restrictions of general relativity (unlikely).
