Guns, my point is precisely that nothing requires chance or, if I grant that there are probabilistic events (possibly quantum events), they have no effect on a macroscopic scale. It's the reason you assume everything remains the same that is not affected by the point of divergence. You're first point is a non-sequitur but is correct, the light cone of an event A (a POD) 2,000 years ago will only be a 2,000 light-year radius sphere, it being physically impossible for the POD to affect anything outside this sphere. Thank you for bringing that up, Guns.

Sorry, Von, you've misunderstood. When I say you've ignored things I mean there are facts that render these thoughts of yours wrong in theory (and in practice). That's what my three points were outlining. I did not mean that you missed out certain possibilities.
