Nothing had to eliminate them, because they were never there in the wave function in the first place.

Not really. The bolded phrase is correct for Bohmian mechanics, but it's not correct for the MWI. In the MWI, all outcomes are...

I don't think so; AFAIK there isn't any question about which branches there are. The question is about how MWI explains the branching...

But in the MWI, all branches correspond to actually occurring outcomes. In Bohmian mechanics, only one does. That's a big difference.

This is not a valid reference. Can you find a valid reference (textbook or peer-reviewed paper would be best) that says what you're...

No, this is not correct for Bohmian mechanics. In Bohmian mechanics, outcome information is contained in the unobservable particle...

In QFT there is no wave function, there are only quantum fields. How QFT captures nonlocality is more complicated than it is for...

If you're going to bring in relativity, you can't use non-relativistic QM; you have to use QFT. So you need to go find a reference that...

You're assuming that decoherence can distinguish HT from TH. If that's true, it's just an example of how different outcomes don't have...

It means the cat is already decohered into the "alive" and "dead" states as soon as the poison is released and reaches it, no matter how...

I don't know, because "any direction" might still not be a continuum, if there is not a continuum of states that the environment can be...

Possibly, or possibly not. Even if it does, there aren't necessarily a continuum of things to interact with. Yes, this is probably true...

Why? As has already been said, "branching" in the MWI occurs as a result of decoherence. I see nothing at all about decoherence anywhere...

Only if there is something that decoheres as a result of each direction. But there won't be a continuous infinity of such somethings...

No. I said that about the claim that the MWI has been falsified. That's not what's being discussed in the post you quoted.
