I made some mistakes in my last post.

Hi, I'm new to this mailing list. I have a question regarding Everett's

MWI. How and why is there a more likely probability of certain states than

others? Everette proved that the same probability laws exist in every

world. I have read that some states are more likely to be our world because

there are more worlds corresponding to that state than other states.

Normally, I would assume that the probability laws describe how many worlds

there are corresponding to a given state, but as far as I understand it, any

two different worlds existing in exactly the same state is strictly

forbidden. Considering that every possible state does exist in some world,

it seems safe for me to conclude that there is only one world corresponding

to every state, and the chance of finding ourselves in any possible universe

is just as likely as any other. The result would be total chaos. It is

obvious that this is not the situation.

The only possible explanation I can think of is that the probability laws

don't describe how many worlds of a given state exist, but rather directly

describe the actual likelihood of a given world being ours. But this

description doesn't make sense either, because for every split in which we

are favored to follow a certain world, there exists another world of equally

real people who assumed they would they would follow the same path, who

instead ended up in the so-called unlikely world. Because the people in

both worlds are equally real, there is no way to say that we are more likely

to follow either path; rather, between this single-split example, the chance

would be 50/50 as to which world we would end up in. Considering all

possible worlds, we are back to the drawing board - the chance of us

actually being in a world that isn't chaotic is pretty much nonexistant.

So, how does the MWI explain the stability of our world?
