I think space is like a giant piece of blackout drape fabric on a loop; you go so far and find yourself at another point on the other side or something. Maybe it's a sphere and the internal edges carry you on a conveyor to another point. It's so large that if you tried travelling to you the end you wouldn't realize the transition, like if you tried to swim across the ocean in a straight line and before you know it you've swam in a circle. As for heaven it could be in the general 'up' direction but if it's part of the spirit realm, on another plane there's probably no fixed position anyway. Like a constantly flying celestial airbus A380. Then again is heaven even a 'place' like a building. It'd be more like a floating island with buildings and the populus makes the place.. One thing though, Christians don't believe spirits/souls go straight to heaven, as far I know. I've forgotten what we're ramling about, actually, I couldn't read most of the original post... I think I need to smoke now.
Well, not hate the planet, we are steward of the planet, in the world but not of it; we have to hate worldly things.
