    March 28, 1992 issue of New Scientist, page 23, has an interesting
article reviewing an article in Physical Review D (October 1991) in which
David Deutsch of Oxford uses the many-worlds hypothesis to show how one can
how time travel without the paradoxes of killing your grandfather.  He
argues that if you could travel back in time, you would end in a parallel
universe, whose future you could affect, without affecting your own future.
Interesting articles.

    By the way, almost all time-travel paradoxes involving death paradoxes
usually involve going back and killing your grandfather or father.  Aren't
we physicists supposed to be humanitarian and objective, and minimize the
destruction by going back and killing ourselves as children?

Just a thought  :-)

But you *could* end up in a precedent of your thread.  How does he preclude
this?
