I learnt that when I was in high school, never really
felt they are sad. All in all, heat death will happen
billions of years later. For example, our sun will
support earth for some 3~4 more billion years before
it evolve to be a red giant.

夏虫也不要去试图理解冰,因为也没有办法了解清楚。
悲哀则来源于对我签名档的逆向理解。

是正确的,这个宇宙有两种结局,跟物质密度有关:大于某临界值,最
终塌缩到一个质点;小于等于该值,死于热寂。根据目前已知的质量计
算的密度似乎才到该值的1/10,不过还有两个重大质量来源不能确定:
宇宙暗物质和中微子。前者是因为看不见,不容易测量;后者好象还没
能确定到底有没有质量,因为它们的数量极其庞大,如果是有质量的,
其质量会构成宇宙质量的极大部分。
