Inflation is a very bold idea, but it seems to be the only way to explain the observed features of the universe.
Your time is limited, so don’t waste it living someone else’s life.
道,真实可信,无为且没有形相,可以流传而不可以传授,可以得到却不能够看见;自己便是本根,没有天地之前就已经存在;鬼神天帝因它而化,天地因它而生;在太极之上而不为高,在六合之下而不为深,生在天地之先而不为亘久,长于上古之时却不为老。
"To live is to be in constant dialogue with death."
