From your blog and your paper, your idea seems to be that the quantum state of the universe is a superposition, but only one branch at a time is ever real, and the selection of which branch will become real at a branching is nondeterministic. Well, Bohmian mechanics gets criticised for having ghost wavepackets in its pilot wave - why are they less real than the wavepackets which happen to be guiding the classical system - and you must be vulnerable to the same criticism. Why aren't the non-dominant branches (page 11) just as real as the dominant branch?
Thank you for your feedback Mitchell,
I'm afraid you have not understood the paper correctly. First, if a system is in a superposition depends on the basis you use to expand it, it's not a physical property but one of description. The mechanism of branching is actually derived, and it doesn't come from superpositions but from eigenstates of the tensor factor space description that an observer is unable to reconstruct. The branching is also perfectly deterministic. I think your best option to understand how the dominance of one branch and the non-reality of...

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.

I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
