Witness Hypothesis v1.3

Abstract

The Witness Hypothesis v1.3 challenges established concepts of time from two perspectives: "time that no one is watching" and "time that is watched but is meaningless." It argues that the existence of time requires an observer to generate a single reality with "decisive weight," as the Many-Worlds Interpretation (MWI) nullifies the meaning of individual choice and collapses ego identity.

Infinite Mirror Hypothesis v1.0

Takao

The Infinite Mirror Hypothesis questions the collapse of self-identity that occurs when the logic of the Many-Worlds Interpretation (MWI)—which claims that "all possibilities are realized"—is taken to its ultimate conclusion. In the Many-Worlds Interpretation, the universe branches infinitely at every choice and every moment. As a result, the existence of "I" is infinitely duplicated, reflecting endlessly like images in a mirror. Starting from the simple question "Why don't time travelers from the future come to us?", this hypothesis points out that while the Many-Worlds Interpretation is "a theory that affirms everything," it is actually "a theory that can specify nothing."

Witness Hypothesis v1.4

Takao

The Witness Hypothesis questions "the existence of time without observers." Can we truly say that "past events" like the beginning of the universe—which no one witnessed—really happened? Starting from this simple question, it asks whether Block Universe theory can claim completeness while the scope of "everything already exists" remains ambiguous. The time of stones, the past of rivers, the beginning of a universe without observers—do they "exist," or are they "treated as non-existent"? This hypothesis stands at that boundary, gently offering a question to which no one has an answer. Keywords: Observation Problem, Block Universe Theory, Ontology of Time, Philosophy, Interpretation of Quantum Mechanics

Can Both the Many Worlds and the Copenhagen Interpretation be True

Dmitri Martila

The Many Worlds Interpretation (MWI) was proposed by H.Everett. It has sounded like most senseless stuff to the scientists of his time, but today it is one of the leading interpretations of Quantum Mechanics (QM). I argue that this interpretation does not conflict with the conventional interpretation. Namely, the observer whose mind does not depart from Our Universe must use the Copenhagen Interpretation (CI).

Many-Worlds Interpretation of Quantum Mechanics: A Paradoxical Picture

Amir Abbass Varshovi

The many-worlds interpretation (MWI) of quantum mechanics is studied from an unprecedented ontological perspective based on the reality of (semi-) deterministic parallel worlds in the interpretation. It is demonstrated that with thanks to the uncertainty principle there would be no consistent way to specify the correct ontology of the Universe, hence the MWI is subject to an inherent contradiction which claims that the world where we live in is unreal.

Problems with Probability in Everett's Interpretation of Quantum Mechanics

Casey Blood

In the many-worlds interpretations (MWIs) of Everett and others, if I am the observer, there are several versions of me but no version is singled out as the one corresponding to my perceptions. However, it can be shown that the probability law implies one version must be singled out. Thus MWIs do not provide a sufficient basis for probability. If we are to have an acceptable description of the physical universe, MWIs must be supplemented by some mechanism, such as hidden variables or collapse, that singles out one version of the observer as the perceiving version.

The Quantum Many-Worlds Interpretation, Simply Told

Brian C. Odom

The many-worlds interpretation (MWI) of quantum mechanics poses a simple question. What would reality look like if everything evolved in time according to the same quantum equations? There is an attractive consistency to treating microscopic objects, measuring devices, and observers all on the same footing, but do the predictions match our observations? Here, we build a model for a bolometer detector making a which-path measurement in an atom interferometer. We discuss the MWI claim that, while both measurement outcomes occur in each experimental iteration, an observer will experience only one outcome or the other, with a probability consistent with experiment. Finally, we discuss how MWI does not have action at a distance. This article is written to be accessible to anyone with an undergraduate course in quantum mechanics.
