There are a series of lectures given by physicist David Deutsch
which can be viewed here:
http://www.quiprocone.org/Protected/DD_lectures.htm
which concern theoretical quantum computation.
In the first lecture, the viewer is asked to discount all the
other interpetions of QM and take seriously that multiverses
are the reality and the only valid interpretation. However,
I found nothing at all in any of the presentations that
makes his case.
It seems to me that this is another case of dishonesty
in science. If David had started off by saying something
like, "Ok, my references to a multiverse are just a game
I play mentally ... and prefer to consider multiverses as
actual or real rather than a artifice ....", I would admire
his intellectual honesty. All he's doing, so far as I can
tell, is following the "logic" and rules of QM ... the
multiverses explanation/interpretation is irrelevant.
Why do so many top notch scientists choose to engage
in religious wars?
