Many-Worlds QM Tested by Quantum Chemistry: a New Kind of Reaction Rate

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 ${\rm Br}_2$. 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
