Net, net, (if I did the right math?) at an assumed expansion rate of 1/2 the
speed of light, we would have been 9 billion light years apart 12 billion

billion years old. No matter how you slice it, we have a paradox unless the
big bang created initial velocities greater than the speed of light. Other
thoughts?

There's nothing to say that space-expansion can't proceed faster than
light; the 'speed limit' applies to objects moving *through* space.
