CI has wave-form collapse. This isn’t used in the mathematical formalism because there’s no specific point at which it’s agreed to happen. It’s just assumed that it is when the system gets “macroscopic”.
They do show evidence of alternate universes, and they are not unobservable. For example, the double-slit experiment has two pasts. One for each slit.
Also, according to timeless physics, the past and future is just alternate universes. If you believe the past exists, and you accept the basic idea, you believe that alternate universes exist.
