ビッグバンの1秒後の膨張率がわずかに小さければ、現在の大きさに達する前に再び崩壊していたでしょう。一方で、百万分の一でも大きければ、宇宙は星や惑星を形成する前に急速に拡大していたでしょう。

If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.
