Trying to Understand Many-Worlds Interpretation Better

[Surgenator]

Alright, so I have some idea of how Many-Worlds interpretation works and why it's accepted by many top experts in the relevant fields as the most logical explanation (since it's seen as the most parsimonious and logical explanation for what goes on in the quantum world).

I, for one, do not accept this interpretation as true because I do not put such a high trust in our logic to explain bizarre things that go on in there, so I'm perfectly happy (for now) with the Copenhagen interpretation.

I don't know if you can test which interpretation is correct. All the interpretations produce the same results, so we can't differentiate them.

But what I'm interested here in this thread is what exactly does Many-Worlds interpretation imply if it is indeed true.

That you might have a T-rex walking through your living room in some other dimension. Other than that, nothing.

Must quantum immortality logically follow from the truth of MWI? Are we really each an immortal character in our own universe?

No. The laws in other universes don't change after a split.

What bizarre things on the macro level have been witnessed in this particular universe that we share (if we even do share the exact same universe) that may hint at the truth of MWI?

Currently nothing.

What does this tell us about the possibility of Christianity or other religions (or gods) being true? If they are impossible here, would they still be considered impossible in all the other universes no matter how many parallel universes there may be?

Laws of the universe still don't change. So any gods that arise will be limited by the universes laws. Still a no go for Xtians.

What does this tell us about the ability to predict anything in the future given that MWI is true?

Same it has been if Copenhagen interpretation is correct.

Finally, how do you feel about MWI being possibly true?

I feel very uneasy about it. I'm not very fond of idea of multipling the number of particles from each measurement. Also, I don't know why can't two or more universes can't interfere with each other.
