Science is all about observability, measurement, and what actually
exists.  If you wish to speculate that something that is never
measurable, observable, or otherwise detectable must still exist, you
need evidence.

The correctness of the prediction of the distribution says nothing
about whether other worlds (presumably you mean with different
distributions) exist.

Yes.  They are generated by the experiment; they do not have the
ability to retroactively change the result of things before they were
generated.  (No, there is no "but at the moment of their generation"
confusion: first they are generated, then they have a span of
consciousness.  Consciousness is over a span of time, which like all
spans has a beginning and an end - granted, this span may also include
interruptions such as sleep.)  Therefore their potential
post-experimental existence can not change the outcome, so they have
no choice but to accept the results.

It's like a certain basilisk AI, whose full name some members of this
list would feel better if I did not spell out.  Hypothetically, it
will resurrect (via simulation if necessary) everyone who knew it
could exist but failed to devote their efforts to bring about its
existence - basically God, with everlasting Heaven for its loyal
people and everlasting Hell for any uncooperatives (and not bothering
with the unenlightened masses who never heard of it).  But that
requires that it will exist, and will turn out that way, which is not
guaranteed to be the world that we eventually face; the mere
possibility does not change this.
