*About a month ago Sean Carroll uploaded a very good video

*Sure, I'll watch it. But I am still waiting for your reply to my
question, posed around 10 times, why, based on S's equation,
every thing that can happen, MUST HAPPEN. *
Basically it boils down to two things. One, they think the
Schoredinger equation is sufficient to described measurement so
long as the world can separate into independent copies for each
eigenvalue of the measurement. Exactly how this separation
proceeds and how it is originated is sort of hand wavy, but
they're sure it can be squared. Second, they want everything to
be deterministic. So having all but one of the world's go away
would require randomness per the Born rule. At one time they
thought the Born rule was already implict in the Schoredinger
equation. But since everything happens it's not so clear what it
means that probabilities are equal to the squared amplitude.
Probability of what? Not probability of a value happening.
Probability of finding oneself in a particular world? How does
the probability amplitude of a quantum event get to apply some
kind of "weight" to you or to a world? One my say "That's just
the way it is. If it's probabilistic then it must follow Born's
rule by Gleanson's theorem." But then that's assuming it's
probabilistic, not just Schroedinger's equation...in which case
why not just bite the bullet and says it's the probability that a
particular world exists.
Because to me in itself, only one world is absurd... as absurd that my
life is finite and preceeded by an infinite time in the past and
infinite time in the future...
You think it absurd that you didn't exist in the past and after a finite
time you will no longer exist?? Most people, and physicists, think
that's the case.
I know reality doesn't have to please me, but one world theory is as
absurd as absurd can be imo. Only a theory about information where
everything exists seems lesz absurd, yeah there is a gazillion things
in it, so there is also in one world, thing is with MW like things,
there is an explanation for you to be, you're one of the
possibilities... in one world, you're one possibilities realised
whatever that means against all not realised whatever that means, the
realised thing is the absurd.
It's just improbable, which is quite different from absurd. Every hand
of bridge I've been dealt was improbable, but I never considered one absurd.
