Oh, it's a duzey, Alamo-Girl! Got it and read it. I thought this statement was simply fascinating:
"If we identify the orbit in the l/s plane with that of a particle, we have a realization of the old idea (often attributed to Wheeler and/or Feynmann) that instead of there being 1080 particles in the visible universe there is in fact only one which appears 1080 times."
That'll give us something to think about!
This 5D "two times" metric with signature [+(- - -)+] puts some flesh on the bones of our speculation about a fifth, "time-like" dimension. It is particularly interesting that Wesson says his work applies in both the induced-matter and membrane theory scenarios.
Thank you so much for steering me to this most interesting article!
