It has to do with the paths and directions of world lines. In the BB singularity, all the world lines appear to start at the singularity. In a BH singularity, all the world lines appear to end. I put appear there simply becuase we don't know what happens at the singularity.

Well, if he's doing that, I have no objection (well, I have a few, but the other objections to his idea aren't part of his use of singularity). His first few posts sounded to me as if he was claiming the singularity itself was responsible for the creation of matter. I was just pointing out that he misunderstood what a singularity is and needed to get away from that specific idea.
Aki, I know you (and Russ) have more questions out there (and I have a few in other threads) and I will try to get to them over the next couple of days. We have people out at work and I'm having to spend more time there and some at home, which is cutting into my posting time. I will get to them (not necessarily in the order they were asked), it's just gonna take a bit of time.
