Description
Recently, a prominent critic of the Many Worlds (MW) interpretation summarised: 'Its main shortcoming is simply this: The interpretation is completely contentless.' In my talk, I will adopt a more generous approach and ask: What if we equip the MW interpretation, specifically its central notions of 'worlds' and 'branching,' with physical content? I will then present a no-go theorem, asserting that this endeavour is doomed: If one attempts to render these MW notions compatible with quantum theory, one will inevitably encounter contradictions.
