Dr. Stephen Hawking asked a question on Yahoo Answers. His question was How can the human race survive the next hundred years?
I don’t have an answer though. Maybe he had figure out something as powerful as nuclear fission but wavering that humankind should know it.
史蒂芬‧霍金博士(Dr. Stephen Hawking)在Yahoo Answers(算是美國版的奇摩知識+)問了一個問題：「人類要如何繼續生存一百年？」。
我沒有答案。說不定他問這個問題是因為他想到某個重要的理論(像上個世紀初的核分裂)，但是不知道人類該不該知道這件事情。
