This isn't true. The further away a galaxy is, the faster it recedes relative to us, and this can amplify well beyond the speed of light. This means different r

  Ah, right. If we consider every inch of space expanding, then long enough distances WOULD expand faster than the speed of light. Doesn't this imply that there is a reverse event horizon around every point in space? That we are on the inside of an inside-out black hole?

    Indeed it does, there's a distance from beyond which light and information can never reach us. That's the notion of "observable universe". http://en.wikipedia.org/wiki/Observable_universe http://en.wikipedia.org/wiki/Observable_universe

    That's an interesting idea. My answer would be that even though every volume of space would be contracting if you reversed the clock, each of these volumes don't form their own singularities, instead the near-singularities coalesce at the point of the big bang.
