上期节目的最后,我跟你讨论了一个看起来很简单,其实深挖下去很深刻的问题,从量子层面考虑,为什么科学家在寻找外星生命的时候,总是先考察一颗星球上到底有没有水,为什么生命就必须得有水,也就是H2O这种物质。可能你会在直觉上觉得科学家太保守了,一点想象力都没有,但当我们从微观世界原子和电子之间的关系,一路推演到形成多细胞复杂生命必要的条件,你就知道,还真就得是H2O这种看起来普通、实则非常特殊的物质,才能支持生命。

多朋友意犹未尽,还想让我聊聊,我们地球上的生物都是碳基生命,那硅基生命可能存在吗?我们有可能在这个物理规律的宇宙中,找到硅基生命呢?

这一期,我们就从物理层面,聊聊这件事。

附带一张元素周期表:
