近年来，粒子物理学家、弦理论家和宇宙学家们逐渐意识到，所有这些多元宇宙的设想，很可能是殊途同归。 历史上的多重宇宙 " 上帝真有可能创造了几百万个世界。 " 这是大哲学家康德在1746年写下的话。康德不仅是哲学家，还是一些重要的现代科学门类的奠基人，比如社会科学中的人类学，比如自然科学中的宇宙星云 说。再过几十年，或许康德还能凭上述这段话，成为另一个科学领域的先驱人物：多重宇宙理论。 不过其实康德远不是多重宇宙最早的倡导者。早在古希腊，前苏格拉底的哲学/科学家们就思考过多重宇宙问题，尤其是其中的原子论学派，也就是留基波 和他更有名的弟子德谟克利特。虽然他们的著作佚失在历史长河中，但后来的罗马主教、基督教神学家希坡律陀却在他的护教著作《驳一切异教邪说》中， 以反面典型的方式，为我们留存下原子论者的多重宇宙观： "' 德谟克利特 ' 教导说，物质总是在空无中运动，存在不计其数、大小各异的世界；有些世界中既无太阳也无月亮，而另一些世界中的太阳和月亮则规模较 大，还有些世界中存在着多个太阳和月亮。各个世界间的距离也不一样，忽大忽小；一部分世界正在增长，一部分世界处于巅峰，一部分世界行将消失，此 处成形，彼处消亡；一旦 ...
