They never knew what would happen to the world a hundred years later.
这里would happen是和knew语态一致还是know的虚拟语气。

knew 表示过去时态.
would happen才是虚拟语气
这句话意思是: 你永远不会知道100年后世界会发生什么.
我举个例子啊
-- I should have told her my number.我应该告诉她我电话的(should have done过去应做而未做)
-- I knew it.我就知道(knew 也是过去,表示过去就知道了)
所以这个句子的knew也应该这样理解,不知道你明白没有!
