Quantum mechanics many worlds” interpretation

If you are not comfortable knowing that you are immortal in pi, maybe you can be comfortable with the idea of Quantum Immortality. To understand this concept, first we must understand the many-worlds interpretation of quantum mechanics. Hugh Everett Ill s doctoral thesis, Relative State Formulation of Quantum Mechanics (reprinted in Reviews of Modern Physics), outlines a controversial theory in which the universe at every instant branches into countless parallel worlds. However, human consciousness works in such a way that it is only aware of one universe at a time. 

Those who believe in Quantum Immortality say that the many-worlds interpretation of quantum mechanics implies that a conscious being can live forever. The cancer you have will not kill you. Your fatal car accident ten years from now will never take place. The theory also means that suicide bombers continue to exist, even after their backpacks explode. The strange logic for quantum immortality becomes clear in the following paragraph. 

Parallel Universes—Chapter 3 discussed parallel universes and the many-worlds interpretation of quantum mechanics. Readers interested in a lively and critical discussion of this topic should consult Professor Victor Stenger s The Unconscious Quantum (Prometheus Books, 1995). For example, he doubts very much that the parallel universes (in the many-worlds interpretation) all simultaneously exist. He also does not believe that all branches taken by the universe under the act of measurement are equally real. Stenger discusses other approaches such as the alternate histories theory that suggests every allowed history does not occur. What actually happens is selected by chance from a set of allowed probabilities. 

Thus, the wavelength-frequency relation (2.1) implies the Compton-effect formula (2.10). The best we can do is to describe the phenomena constituting the wave-particle duality. There is no widely accepted explanation in terms of everyday experience and common sense. Feynman referred to the experiment with two holes as the central mystery of quantum mechanics. It should be mentioned that a number of models have been proposed over the years to rationalize these quantum mysteries. Bohm proposed that there might exist hidden variables whieh would make the behavior of each photon deterministic, i.e., particle-like. Everett and Wheeler proposed the many worlds interpretation of quantum mechanics in which each random event causes the splitting of the entire universe into disconnected parallel universes in whieh eaeh possibility becomes the reality. 

There are no objections, I think, to accepting this historical interpretation the effort of many scientists, including among them eminent leaders such as Boltzmann, Planck, Einstein, Lorentz, and Debye, to name a few, later crowned by the new formulation of quantum mechanics, has provided the basis for a description of material systems which unifies physics and chemistry and constitutes the conceptual world in which we, theoretical chemists, are working.
