多世界诠释 

薛丁格貓,開盒的一刻世界分裂。[1]在這種解釋中,每一個事件都是一個分支點。

多世界詮釋(英語:the many-worlds interpretation缩写MWI)是量子力學詮釋的一種。它是一個假定存在無數個平行世界,并以此来解釋微觀世界各種現象的量子論詮釋,其優點是不必考虑波函數塌縮。該理論也被稱為相對狀態提法、艾弗雷特诠释、普遍的波函數、多宇宙詮釋,或者多世界理論。

1957年,最初的相對狀態提法由美國量子物理學家休·艾弗雷特发表[2][3]。后来在1960年代和1970年代,这一理論普及,并由布莱斯·德维特更名为多世界理论[1][4][5][6]退相干方法在解释量子理论方面得到了进一步的探索和发展,[7][8][9]因而相当受欢迎。多世界诠释是物理学哲学众多平行宇宙假说之一。除了多世界詮釋,目前的量子力學詮釋主要還包括:退相干詮釋、坍縮詮釋(又分客觀性坍縮詮釋和傳統的哥本哈根詮釋)、隱變量理論(主要是非局域隱變量理論例如德布羅意-玻姆理論)等等。
