Would you like to elucidate as to why you consider it to be a dead-end? Again, I am not trying to appeal to authority here, but at the very least, a man of Gerard 't Hooft's stature declaring that he - after decades in the field - is now content with quantum mechanics, ought to be worthy of a...

Gerard 't Hooft has been a renegade in Quantum Foundations for quite some time, insisting that there is natural order underlying the Quantum Mechanical mysteries. Essentially a local, deterministic hidden variable perspective. He has recently posted a new paper on arXiv where he lays out his...

Back in the day, there were a few Quantum Interpretation polls on here, as of late I have not seen any. I love that we now have a sub-forum for Foundations discussions. I figured it would be interesting to see how the participants of PhysicsForums feel about the different interpretations these...

I am well aware of MWI's longstanding problems with probability, but doesn't "DH" really just skirt around this issue by saying that "There's some indeterminism that randomly selects one real world"?

If it doesn't define how one 'real' history occur, then it's just semantics?

As someone who's frequented this board off and on for the past ~15 years, this is actually interesting. What convinced you that the objections (primarily probability related) were not sufficient to render its compelling nature moot?

Isn't DH the same as Everett? Reading James B. Hartle it's hard not to conclude that

Did you become an Everettian in 2020:))

This question is moot if you consider the approach of 'Diverging Worlds' by Simon Saunders, David Wallace, David Deutsch, Alastair Wilson, Anthony Aguirre, etc. I.E. All world lines are spawned at the dawn of existence itself and are always qualitatively separated.

If, as quite a lot of MWI supporters speculate, observers are tied to one branch since the inception of the universe, doesn't that explain this open question? I.E. every universe is isolated from all others, equivalent to other planets in a different spatial area of our universe?

I am still struggling a bit with this. While I am of course well aware of the laws of physics in general, I still struggle to see how the usual understanding of them don't go out the window with MWI. Naturally anything that violates energy conservation is impossible, like a perpetuum mobile, but...

Wilczek is a Many Worlder according to all google results I can find

Wouldn't this require that said black hole already preexisted on the branch? Or are you saying that it has a non-zero probability of just suddenly "happening"?

So then going back to the example Michael Price gave: how would he become president in at least one branch? That whole argument was based around the particles reconfiguring spontaneously and putting him in the white house while also reconfiguring the particles making up the brains of everyone to...
