The fundamental absurdity of single-history frameworks becomes clear when we consider the reliance on theoretical constructs that, by definition, never exist and never will. How can one justify using mathematical tools that invoke nonexistent possibilities to explain a reality where only one sequence of events is ever realized? If something never existed, has no causal influence, and will never exist in any possible future, how does it play any role in explaining what does exist?
This contradiction is evident in interpretations like Bohmian mechanics, where the pilot wave guides particles but remains completely unobservable and uninteractive beyond that role. It’s an invisible, untouchable entity that affects matter but is never affected in return—something that is functionally indistinguishable from the pure abstractions of probability waves in a single-world interpretation. In both cases, explanations rely on constructs that have no true existence beyond their mathematical form. A single-history universe that leans on unrealized possibilities to justify probability is making an implicit appeal to something that doesn’t and will never exist. It treats the wavefunction as a real tool for calculating outcomes while simultaneously denying that the alternatives it describes have any grounding in reality. This is the absurdity: how can something that never existed be part of an explanation for what does? In contrast, in a many-worlds framework, all possibilities exist and are real branches of the wavefunction, providing an actual basis for probability. The probabilities are not just mathematical conveniences; they describe distributions of real outcomes across real histories. This removes the need for metaphysical hand-waving about non-existent possibilities influencing reality. If physics is about describing reality, then relying on things that are, by construction, eternally non-existent to justify observed phenomena is conceptually incoherent. It is an attempt to have it both ways—to use abstract possibilities when convenient while denying their reality when inconvenient. That contradiction is why single-history frameworks ultimately fail to provide a satisfying foundation for probability and existence itself.
