Question

Is a many-worlds philosophy in quantum mechanics, where outcomes are duplicated across branches of the universe, equivalent to the Copenhagen interpretation regarding the interpretation of probabilities and decision-making? How does the duplication of successful outcomes in a many-worlds scenario impact the traditional interpretation of probabilities based on the likelihood of specific outcomes for a unique observer's future, as seen in a scenario involving betting on quantum spin measurements?

Answer 1

The many-worlds philosophy in quantum mechanics and the Copenhagen interpretation have different views on the interpretation of probabilities and decision-making. In the many-worlds philosophy, outcomes are duplicated across branches of the universe, while the Copenhagen interpretation focuses on probabilities for a single observer.

Step-by-step explanation:

The many-worlds philosophy in quantum mechanics and the Copenhagen interpretation have different views on the interpretation of probabilities and decision-making.

In the many-worlds philosophy, outcomes are duplicated across branches of the universe, resulting in multiple versions of reality. Each version experiences a different outcome, and the probabilities are assigned based on the branching of possibilities.

In contrast, the Copenhagen interpretation views probabilities as representing the likelihood of specific outcomes for a unique observer's future. This interpretation does not involve the duplication of outcomes.

The duplication of successful outcomes in a many-worlds scenario does not impact the traditional interpretation of probabilities in the Copenhagen interpretation. Each version of reality in the many-worlds philosophy has its own set of probabilities, while the Copenhagen interpretation focuses on the probabilities for a single observer.
