Analysis of the Mainstream Interpretation of Quantum Physics

Quantum physics is changed in an unexpected way. Scientists believe that the study of quantum will play important role future technology. Therefore, it meaningful to physics. The aim this paper provide initial explanation world through classical single particle double-slit interpretation experiment, and answer a few questions about experiment using mainstream mechanical interpretations, such as Copenhagen Many-Worlds interpretation. superposition state, which core interpretation, then introduced. Einstein-Podolsky-Rosen paradox locality are also introduced, relationship between latter special relativity analyzed. author discusses whether non-locality leads retrocausality. Finally, multi-world Schrodinger's cat, but may raise some philosophical questions. However, realist hidden variable consistent long abandoned.
