Why aren't they all where? If they were 'here' then they wouldn't be
another world now would they?

If they could communicate they wouldn't be different.

It's muddled thinking raised to a lot of wasted human effort.
ps there are -two- different ways to propose the 'many worlds' model. The
first being that the worlds occupy the same 'space' but differ in all
other characters; in other words they are the same cosmos but with
different 'decision trees'. The other is that they exist in a
'meta-space' that seperates -all- metrics; that the many cosmos' are
truly each unique and share nothing (note that this model can also
contain the first).
