In a strict meaning it is a self-contradiction: as the World splits into two (many) Worlds, we have many of them, not one.can you subscribe to the many-worlds interpretation while also believing there is only this one universe
The many worlds interpretation of quantum mechanics is a theory that suggests that every time a quantum measurement is made, the universe splits into multiple parallel universes. This means that every possible outcome of a quantum event exists in a different universe.
The many worlds interpretation differs from other interpretations of quantum mechanics, such as the Copenhagen interpretation, in that it suggests that all possible outcomes of a quantum event actually occur, rather than just one being selected.
The many worlds interpretation is often used to support the idea of a multiverse, which is a hypothetical collection of parallel universes that exist alongside our own. In this theory, each universe in the multiverse would contain a different version of reality based on the different outcomes of quantum events.
Currently, there is no direct evidence to support the many worlds interpretation. It is a theoretical concept that is still debated among scientists and philosophers. However, some argue that the concept of a multiverse could help explain certain phenomena, such as the measurement problem in quantum mechanics.
The many worlds interpretation challenges our traditional understanding of reality, as it suggests that all possible outcomes of a quantum event exist in different parallel universes. This means that there could be an infinite number of versions of ourselves and our universe, which can be a difficult concept to grasp and raises philosophical questions about the nature of reality.
