He possibly also returned back before he left ?

GOSH!

We would have then TWO Safartti sending posts to sci.astro...
Then one that returned after travelling through the stargate,
and the one that did not move at all.


I heard and saw (public video in the internet)
Dr. Paul Davies' public lecture about "black holes
and time travel". This above paradox was mentioed as one
possible paradoxes in his lecture which follows
in his opinion from time travel if it would be possible.

Davies's example roughly:
Person starts from the spacetime point A then he goes
into the first end of the wormhole

(this stucture was explained to be a structure as follows:
1. black hole
2. an open area around black hole's singularity
3. white hole [= time reversed black hole and its
singularity is same as blackhole's])

and he comes out from the other end of the wormhole to the
spacetime point B and lastly he makes a closed timelike loop
(spacetimelike loop ?) back to the spacetime point A.

The result was that he arrived back to B before he left
from A. And one interpretation was indeed that there would
be TWO of the same person at the spacetime point A.

This may explain why Sarfatti has posted so numerous lonely postings
recently to sci-groups ?
