Abstract Quantum physics is changed in an unexpected way. Scientists believe that the study of quantum physics will play an important role in future technology. Therefore, it is meaningful to study quantum physics. The aim of this paper is to provide an initial explanation of the quantum world through the classical single particle double-slit interpretation experiment, and to answer a few questions about the experiment using mainstream quantum mechanical interpretations, such as the Copenhagen interpretation and the Many-Worlds interpretation. The superposition state, which is the core of the Copenhagen interpretation, is then introduced. The Einstein-Podolsky-Rosen paradox and locality are also introduced, and the relationship between the latter and special relativity is analyzed. The author also discusses whether non-locality leads to retrocausality. Finally, the author discusses the relationship between multi-world interpretation and Schrodinger’s cat, but this may raise some philosophical questions. However, realist and hidden variable interpretation are also consistent as long as locality is abandoned.
This research aimed to achieve 2 primary objectives: 1) To study Schrödinger's cat theory and the concept of multiverses, 2) to analyze the interpretations of Schrödinger's cat theory and the concept of multiverses. The data analysis is descriptive.The research results were as follows:1. Schrödinger's cat theory and the Multiverse concept have shown that Schrödinger's Cat theory is a thought experiment in quantum mechanics proposed by Austrian physicist Erwin Schrödinger. It describes the simultaneous multiple states of an atom or entity until it is observed or measured. For instance, in the famous cat-in-a-box experiment, before measurement, the cat exists in a state of both being alive and dead simultaneously, leading to a complex reality in its state. Physicist Hugh Everett later introduced the Many-Worlds Interpretation to address the complexities, giving rise to the concept of parallel universes and the Multiverse.2. When interpreting Schrödinger's cat theory and the multiverse concept, it was discovered that within the framework of Western physics, they involve deductive reasoning and fall into the category of quantity and approximation. However, when interpreted within the framework of Indian metaphysical philosophy, they are associated with inductive reasoning and belong to the category of inference and approximation. This contrast highlights how Schrödinger's Cat theory can be a valuable philosophical tool for discussing ideas related to parallel universes and the Multiverse, especially when considering different approaches to interpretation.These findings shed light on the significance of Schrödinger's Cat theory as a philosophical instrument for exploring the concepts of parallel universes and the Multiverse and for considering the possibilities of diverse states for events occurring simultaneously, even when we only observe a fraction of them.
Standard quantum theory is highly successful in all its applications, from photons and atoms, to semiconductors, superconductors, quarks, and so on. Yet the need to understand what the theory is really trying to tell us about the nature of the world beyond specific predictions forces us into the realm of philosophy, or, as some have dubbed it, quantum metaphysics: the study of the interpretation of quantum mechanics. There is a wide range of opinions regarding the philosophical foundations of quantum mechanics. This chapter focuses on two of the most prominent interpretations: the Copenhagen interpretation, and one alternative interpretation that has been gaining some support in recent years, the many-worlds interpretation (MWI), also known as the many universes interpretation. The central issues of contention are: firstly, that the measurement of some attribute of a quantum system generally involves the probabilistic collapse, or reduction, of the state vector where the probabilistic nature of the process is inherent—that is, not reducible to a more fundamental, deterministic explanation; and, secondly, the problem of bringing a measurement to a completion—a problem generally known as the measurement paradox.
The Everett interpretation of quantum mechanics - better known as the Many-Worlds Theory - has had a rather uneven reception. Mainstream philosophers have scarcely heard of it, save as science fiction. In philosophy of physics it is well known but has historically been fairly widely rejected. Among physicists (at least, among those concerned with the interpretation of quantum mechanics in the first place), it is taken very seriously indeed, arguably tied for first place in popularity with more traditional operationalist views of quantum mechanics. In this article, I provide a fairly short (15,000 words) and self-contained introduction to the Everett interpretation as it is currently understood. I use little technical machinery, although I do assume the reader has encountered the measurement problem already (at about the level of the well-known discussions by Penrose or Albert).
abstract: This thesis attempts to explain Everettian quantum mechanics from the ground up, such that those with little to no experience in quantum physics can understand it. First, we introduce the history of quantum theory, and some concepts that make up the framework of quantum physics. Through these concepts, we reveal why interpretations are necessary to map the quantum world onto our classical world. We then introduce the Copenhagen interpretation, and how many-worlds differs from it. From there, we dive into the concepts of entanglement and decoherence, explaining how worlds branch in an Everettian universe, and how an Everettian universe can appear as our classical observed world. From there, we attempt to answer common questions about many-worlds and discuss whether there are philosophical ramifications to believing such a theory. Finally, we look at whether the many-worlds interpretation can be proven, and why one might choose to believe it. (abstract)
In this thesis, I argue that, contrary to the historical opposition between Niels Bohr and Hugh Everett's respective interpretations of quantum mechanics, their views share several common goals and metaphysical similarities. Their theories, while they have their disagreements, make many compatible claims with one another, although the conclusions they reach are different. They went about modeling physical reality in distinct ways, but I argue first that these apparent incompatibilities are not so dissimilar as commonly believed and second that Everett manages to improve upon Bohr's theory for a more coherent account of physical reality. I demonstrate this by 1) looking at Bohr's interpretation of quantum mechanics, as understood by Karen Barad, and his solution to (or perhaps more appropriately, his denial of) the measurement problem; 2) looking at Everett's interpretation of quantum mechanics, in part as made popular by Bryce DeWitt, and his solution to (or denial of) the measurement problem; and 3) comparing and contrasting Bohr and Everett's interpretations in order to show that Bohr's view can be understood as laying down the metaphysical framework for Everett's view, which ultimately leads to a more cogent, consistent, and compelling understanding not only of the measurement problem of quantum mechanics, but also of the nature of the multiverse.
