Schroedinger's cat experiment, my question?

[free30]

People say that the Schroedinger's cat experiment shows the possibility of multiple universes.
Yet if the person checking if the cat was still alive (the measurer) was in a box themselves, your possibilities are limited. And do not include a dead measurer and a dead cat!
Anyhow so for me this shows that there are not an almost infinite number of universes but simply with thought we illuminate the ones right next to us.
Just playing with ideas, anyone one know if this would be true outside Schroedinger's thought experiment?
Thanks

Schroedinger's cat experiment(thought experiment) had NOTHING to do with proving multiple universe's.

Perhaps the most misunderstood thought experiment in history.

Instead, the intent of the thought experiment was to expose natural flaws in human logic and the fallacy of the role of the observer(in this case) determining outcome.

In other words, in reality, the cat is NOT in a state of superposition(alive or dead) until observed, yet the thought experiment might presume this.

Hence the potential for flawed logic. That was his point.

This was NEVER meant to be an actual experiment proving multiple universes.

Shroedinger didn't mean it to be, certainly, but this is the argument for Many Worlds.

We now know that the Shroedinger Cat experiment will go exactly as described, as unintuitive as it seems. While we have not done anything like this to an actual cat, it has been done to some simple systems and all predictions have been met. So Shroedinger was wrong. As crazy as it is, this is how things work.

The next step is to consider what it all looks like to a cat. The living state obviously does not experience its own dead state. From its perspective, the outcome is not a super-position but a certain eigen state. If it's a very smart cat with the right equipment, it can even verify that the radioactive atom's state has collapsed.

The next step in the argument is that since universe is a closed system (presumably) all the same rules apply to us. So what's really an entanglement of observer state to the observed state appears to observer as a collapse of observed state, while in reality, both continue exist as superposition. And that is Many World Interpretation.

OK, so we are able to do the experiment.
Be it a cat, mice or whatever.
Has anyone done this?

I must applaud you for giving the shortest and most elegant explanation for MWI I've ever head!

Th e universe is an open system because it is infinite.
