论文摘要
量子力学（MWI）的许多世界解释指出，我们生活的世界只是许多平行世界之一。人们普遍认为，由于对平行世界的承诺，MWI违反了常识。有些人甚至在此基础上拒绝MWI。尽管它对物理学有无数的优势（例如，与相对论理论，数学简单，现实主义，确定论等一致）。在这里，我们认为常识实际上有利于MWI。我们认为，仅当因果解释是当地因果解释时才是常识性的。我们提出了几个量子机械实验，似乎表现出非本地的“距离动作”。假设只有一个世界存在，这些实验似乎不受当地因果解释的影响。但是，我们表明，通过将所有世界融合在一起，MWI可以提供实验的当地因果解释。因此，MWI恢复了物理解释的常识。
The many worlds interpretation of quantum mechanics (MWI) states that the world we live in is just one among many parallel worlds. It is widely believed that because of this commitment to parallel worlds, the MWI violates common sense. Some go so far as to reject the MWI on this basis. This is despite its myriad of advantages to physics (e.g. consistency with relativity theory, mathematical simplicity, realism, determinism, etc.). Here, we make the case that common sense in fact favors the MWI. We argue that causal explanations are commonsensical only when they are local causal explanations. We present several quantum mechanical experiments that seem to exhibit nonlocal "action at a distance". Under the assumption that only one world exists, these experiments seem immune to local causal explanation. However, we show that the MWI, by taking all worlds together, can provide local causal explanations of the experiments. The MWI therefore restores common sense to physical explanation.
