Re: What is MWI?

....and also by implication: local realism doesn't need to be explained in terms of the big bang; nor determinism; nor any of the other assumptions we are are holding constant. 

MWI is the solution to all these implicit assumptions...and a whole shed load more....and QM Strangeness...all being consistent and part of the same thing. 

That's incredibly fragile....not least because the majority of those assumptions don't appear worked through or subject to much or any interest.
