This is correct with the ABSOLUTE SSA.

So I guess it is the absolute/relative point which distinguish between us. The immortality distinction results. Nevertheless I don't understand you when you say: > Quantum events, then, just cause the implementations to >differentiate rather than creating new ones. I guess you disagree with Q19 of Michael Clive Price's FAQ at http://www.hedweb.com/manworld.htm#detect. Q19 = "Do worlds differentiate or split?" Bruno
