P --
Another great post on the crossing of science and humanity.
Consider: in his deep thinking on the actuality of alternative
histories ("Two roads diverged in a yellow wood"), do you imagine
that the elder Everett was comforted by having a rigorous way to
believe that what might have been actually did happen, somewhere?
If he was disappointed with the way his life had gone ("and that has
made all the difference."), maybe this was his way of mourning for the
missed possibilities. You can see how this would have been rough
on his family and friends....

Meanwhile, a question to ponder: Is the "many-worlds" interpretation
truly a scientific theory? in that, is it falsifiable? We know that a variety
of experiments support Bell's conclusions, which can be said to confirm
the operation of quantum mechanics (at least for small systems), and
if this were not true then Many Worlds would have been ruled out along
with pretty much all other post-Copenhagen interpretations of QM.
But, is there some observation which could rule out Many Worlds while
allowing some other QM framework (say orthodox Copenhagen-ism, or the
"coarse-grained histories" approach of Gell-Mann and Hartle) to survive?

Let me know what you think,

Just remember Peter that the limits of our measurements isn't the limit of what can be understood. For what is known is far more limited by the constraints of our belief of what is possible, than that which truely really exists.
