Having said that how could we be sure that the whole physics is solely explained and governed by deterministic and objective equations? Maybe there is a subjective aspect of monistic physical reality that eludes us because we can not access to it or our current scientific knowledge is not enough for any access to thus aspect. Maybe this is the reason why we are in great trouble in understanding, analyzing or modeling the subjective nature of consciousness or the qualia phenomenon.
By subjective aspect of physical reality, I am referring to some concept along the lines of panpsychism.

The above is a major possibility simply because my interest in MWI has only ever been as one of the objects in the Popperian array. And my interest in *that* has for a long time been very much in terms of understanding how a way of thinking can be so right at the root yet get so distorted and off the rails further down.
I've always done this, I hope, with integrity. In that, whenever Deutsch or anyone has something that I can see possibility in, that I have done the right thing, and gone off and spent time reflecting on it.
So I guess I might have to spend some time trying on, what you are saying.
The problem though, one way or the other, is going to be that, if I come back agreeing or disagreeing, there isn't going to be any way for me to influence your point of view.
This is because you have, or you seem to have, adopted Deutsch's philosophy-based view of Science, which essentially rejects all of the ways that science has invented for criticizing and weighing between possible explanations.
I respect Deutsch...he says its about cleaning up the thinking. And sure, this can be about messy thinking my end. But, the way it looks when I stand back ten feet, is that with all that messy thinking Deutsch has swept away, he's thrown out almost every possible way to criticize and make object judgements.
Now it's just about 'good explanation' and that's just about good philosophy, and that's just popper and deutsch, and you criticize it, but guess what, any criticism you make at any level, is actually pre-refuted by the level above! Or to the left!
And of course, the only way to navigate it all, is by becoming total expert of the whole thing. And people that don't see the promise of a philosophy, or have major doubts, typically don't commit years and years to that subject.
Therefore, the only people that could criticize, are the same people that totally don't have major criticisms. And that is caused by the structure of the philosophy itself, and in effect it makes it impossible to criticize.
So it's the total opposite of what it claims to be, and what it thinks it is. Popperians think that just be saying you're fallible and by preaching it, and just by that being a major component of the philosophy, that this...this...delivers criticism. It doesn't.
And if Deutsch says different, I would ask him to point to the really major concessions that he has made in constructing this philosophy. Or is the story that Deutsch got everything right beginning to end?
It's just never happened. This has all been on a tiny scale. It's like Deutsch and 3 or 4 others, all of them likeminded from the start. It just can't work like that and be consistent with its own philosophy.
Don't forget, this philosophy claims to trump Science. This is now science. Deutsch rejects all the *evolved* ways Science has found to keep the steer on the right path to objective reality. And in their place he has put a conception of criticism that has never actually been applied to his own philosophy in any dramatic way, and never applied to the *structure* of the philosophy and whether that structure actually puts up large barriers to criticism. I'm not even sure popperians know what I'm talking about when I mention things like structural barriers, but it's very common and ubiquitious. Ever heard of non-tariff barriers?
OK back to this MWI thing. I will reflect on what you say. But I would really like you to just take 10 steps back, and look at all the possible options, right across the scientific frontier, for how QM might come to be explained.
And I would like you to drop the popperian standard for a moment, and use a practical standard. Judge which approach would be better, in terms of:
- How many outstanding scientific barriers the solution *potentially* clears up at the same time.
- Whether that avenue of enquiry *promises* falsification events at regular stages along the way.
- The potential for research to have unexpected knock on relevance into other sciences...which note could also lead to developments that eventually worked their back into the mainline research as either criticisms or as new energy in the form of insights that strengthened research.
Use that criteria for a moment. Judge MWI, the last 50 years of it, with that criteria.
And then try on my QM <--> Big Bang formula. You don't have be able to see how that would proceed. Not on this criteria. The only question is whether....since as you say yourself "who knows?"....then just comparing the two routes based on which one is most promising to rule itself out, or lead to dramatic progress.
And then answer me this. Is it reasonable, that given the unfalsiability of MWI, all other avenues that may produce falsifiability should be thoroughly explored, before accepting MWI and putting that at the centre of things?
