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)
Quantum chemists have recorded a huge number of data points which standard quantum mechanics cannot interpret. Many-Worlds quantum mechanics can. Many-Worlds quantum mechanics differs from standard quantum mechanics because in Many-Worlds, the wave function is a relative density of universes in the multiverse amplitude rather than a probability amplitude. In Many-Worlds, the Born frequencies are approached rather than given a priori. Thus in Many-Worlds, the rate of approach to the final frequencies can be calculated and compared with observation. This is a new type of reaction rate. I show how to use Many-Worlds to analyze the breakup of
Br2. Such analysis will experimentally test Many-Worlds fermionic and time-dependent quantum mechanics. Conversely, experimental quantum chemistry has become too sophisticated to be analyzed by standard quantum mechanics. Only Many-Worlds can do the job
The appearing of world is approached via the dream world which has generally been thought to be merely derivative: a "composition" of memory traces from waking life, which are merged and fused into a dream world that in some instances can be indiscernable from the world of waking life. Two dreams are presented which challenge the composition theory of dream formation. An alternative unified theory of world appearance in both waking and dreaming is proposed, which makes use of developments in quantum brain dynamics. For this "monadological" proposal the wake world and the dream world are ontologically at parity. This surprising conclusion extends the quantum revolution to our very Existenz.
