Could someone recommend an article (at advanced pop-sci level) providing the best arguments against the multiverse approach to quantum mechanics.
What is the best textbook that explains quantum mechanics from a multiverse perspective (rather than following the Copenhagen school and then bringing in the multiverse as an alternative)? This should be a textbook, not pop-sci, but at a basic a level as possible.
David Wallace's The Emergent Multiverse is an excellent introduction to the many-worlds interpretation, written by its best defender. Most of it should be accessible to a layperson, although there are technical sections. You can't use it to fully learn quantum mechanics from scratch, though. But if you learn the basic formalism from another textbook (I recommend this one; the first eight chapters should suffice) you'll be able to follow almost all of Wallace.
As for criticism, this is the best non-technical article I know of. It does presume some knowledge ...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
