Does every choice you make create a new universe?
In short: This video breaks down the Many-Worlds Interpretation of quantum mechanics, moving past sci-fi tropes to explain the actual physics of branching realities. It explores why some physicists believe our universe is constantly splitting into infinite versions of itself.
The core of the debate lies in the 'measurement problem' of quantum mechanics. While the traditional Copenhagen interpretation suggests that a quantum system exists in a superposition of states until observed, Hugh Everett proposed the 'no-collapse' idea. In his Many-Worlds view, the wave function never collapses; instead, every possible outcome of a quantum event occurs, with reality branching into different paths.
The video explains why we cannot interact with these other branches, a process known as decoherence. It also addresses the significant hurdles for the theory, including the difficulty of testing these branches and the complex 'probability problem' that arises when every outcome happens. Finally, it touches on how figures like David Deutsch link these concepts to quantum computing.
