是否存在宇宙的起源？在大爆炸之前，时间是连续的吗？宇宙从何而来？
Was there a beginning? Did time continue before the Big Bang? Where did the universe come from?
他们发现在大爆炸发生之前，存在一个收缩的宇宙。
They found that before the Big Bang, there was a contracting universe.
也许有人要问宇宙诞生之前是什么?答案就是根本没有所谓的“大爆炸之前”，就像是说没有比南极点更南方的地方一样。
One might ask what is before that, but the answer is that there is nowhere before the Big Bang , just as there is nowhere south of the South Pole.
