is physically possible happens - i.e. all physically possible outcomes of
each (apparently probabalistic) quantum event. I didn't mean to imply
that *physically
impossible* things happen (and it would have been nice if you'd done me the
courtesy of thinking that perhaps that was what I meant, rather than
assuming that "oh, she must be spouting dubious popularisations!" as you
appear to have done.)
