Question: Is there a plan for how space travel works?
Elaboration: I'd imagine that there are a variety of races with their own ideas, and I'm interested to see how different races solve the problem of interstellar gulfs. By way of example, I mucked around with combining metamagics and permanency on items and found that you could actually create a functioning space ship within the bounds of the rules using dimension doors and adaptation spells. Granted, it cost about as much as an actual space program, but I suppose that's to be expected.
Question: How does magic interact with technology?
Elaboration: If magic and technology do not play nice together (like in the Dresdin Files or Arcanum) where does the distinction lie? You could have a magically enchanted crossbow or pistol in Pathfinder, but what level of technology starts rebelling against magic, if it does? Or can we have the +1 Soda Machine of Vending that we've always wanted?
