Hints:
noneWhen I was a child, after bedtime I would often get out of my bed in my pajamas, go to the window and stare at the stars. I had so many questions. How far away were those tiny points of light? Did space go on forever and ever, or was there some end to space,some giant edge? And if so, what lay beyond the edge?
Another of my childhood questions: Did time go on forever? I looked at pictures of my parents and grandparents and tried to imagine their parents, and so on, back through the generations, back and back through time. Does time go on forever? Or is there some beginning of time? And if so,what came before?
When I grew up, I became a professional astrophysicist. Although I never answered any of these questions, they continued to challenge me, to haunt me, to drive me in my scientific research, to cause me to live on tuna fish and no sleep for days at time while I was obsessed with a science problem.小时候，我常常在入睡前裹着睡衣溜下床，来到窗前凝视满天星斗。我曾有很多的疑问：那些小亮点离我们有多远？太空会永恒地存在吗？没准儿太空也有尽头，有着某种巨大的边缘？如果是这样，置身于边缘之外的是什么呢？
我童年时代的另一个疑问是：时间是永不停息的吗？我注视着父母和祖父母的相片，努力想像他们的父母是什么样子，就这样一直想下去回溯数代，追溯久远。时间是不停息的吗？没准时间也有起点？如果是这样，在时间之前又会是什么样的情形呢？
长大之后，我成了一名职业的天体物理学家。尽管我从没能回答这些问题中的任何一个，可它们仍不断地激励着我、萦绕着我、驱使着我继续从事科研究，让我在着迷于某个科学难题时以金枪鱼罐头为食，连日不眠不休。
