| The "Many Worlds"-interpretation of reality seems to have the nice property
| that "messages from the future" is not such a counter-intuitive
| notion in that model as in more traditional ones. If we receive such a
| message, we simply do not know which one of the possible futures sent it !
| Since all possible events occur in parallel the violation of "causality"
| caused by such a message would not be such a big deal.
| Has anyone got any pointers to some understandable text about the model
| for amateur philosophers-physicists like myself ?
+---------------

No, but I find it interesting that there have been several science-fiction
"time-travel" stories recently for which the "punch line" of the story is
that causality isn't ever violated because the "Many Worlds" view is correct.
(A' sends back a message, which A (an "earlier" A') receives, acts on, and
grows up to be A". Oops!)
