关于时间的脑洞
我觉得时间对于宇宙来说并不存在，或者说对于宇宙来说没有任何的意义，只是人类创造出的一个概念或者是一个错觉。
人类会把时间算作第四维度，但是我却觉得，人类只是错误的把第三维度上增加的透视算作了第四维度，就像是在二维的画面中增加了透视，产生了画面纵深感的“立体感”——对于二维的画面来说，并没有实际多出一个维度，但是人类却可以感觉到近大远小，产生了立体纵深的错觉，第三维度在二维的平面里面并不存在。
最近的全息宇宙理论更加的让我觉得这个脑洞也许是真的。
对于宇宙来说，时间并不存在，所以1年和150亿年没有什么分别，一颗恒星的诞生和消亡，宇宙只关心它的过程，至于耗费了多少时间，对于宇宙来说并没有意义。时间伴随人类文明发展至今，也许，人类一直就理解错了，把错觉当成是现实呢？
或者，也许可以这么理解，当某一个值接近或者达到无穷以后（毕竟人类无法理解真正的无穷），任何一个数值在这个无穷面前都没有意义。
It was the last day I stayed in Yuhu Village at the foot of Yulong Snow Mountain, I got up very early and looked out of window, though there was still dark but I could tell it would be a clear day with strong sunlight. After a quick preparation, I rushed into the dark.
This position I had noticed for a couple of days, it had a better view angle than any other place around, unless hiking onto those peaks, but I doubt my strength ( Yuhu Village has 2600 meters altitude not to mention the peaks…). I have none hiking experience either, it would be a risk to hiking alone in snow mountains blindly so I decided just staying there to wait for the sunrise.
