A fraction of a second after the Big Bang, the universe is so small, it can fit in the palm of your hand. But in another tiny fraction of a second, it expands to the size of the earth. Then moving faster than the speed of light, it grows larger than our solar system, and it's still just a raging storm of super-heated energy.
大爆炸后的短短一瞬，宇宙還十分渺小，跟你的手掌差不多大。之后又一個短短的瞬間，它卻膨脹成地球般大小。接著就以快于光速的速度膨脹。即使擴張得比太陽系還大，大爆炸仍然是一場高熱的能量風暴。
It'll be harder, and denser and more violent than anything that we can experience in the universe today. Even the interior of a star is calm and serene by comparison to the violence of the earliest moments of the Big Bang.
它比人類現在所感受到的任何事物的溫度更高，密度更大，更不穩定。與大爆炸最初相比，即使是炙熱的星球內部，也顯得平靜穩定。
Temperatures were so hot that even the atoms of your body would disintegrate, so hot in fact, that the atoms will be ripped apart.
溫度如此之高，就連體內的原子也會再發生分解。實際上，在如此高的溫度下，原子會分崩離析。
How hot? Trillions of degrees hot. But as the universe continues to expand, it also begins to cool. Dropping temperatures trigger the next stage in the universe's evolution. The raw energy of the explosion transforms into tiny subatomic particles. It's the first matter in the universe. This conversion of energy into matter was predicted by Albert Einstein years before anyone started talking about the Big Bang. It's the one scientific equation every school kid knows.
到底有多熱呢？溫度高達萬億度。由于宇宙持續的擴張，它開始冷卻。下降到溫度引發宇宙進入第二個進化階段。爆炸后的原始能量轉化為微小的次原子微粒。宇宙中第一種物質產生了。愛因斯坦早在人們開始談論大爆炸前就預測能量可以轉化成物質。這是學校的學生也知道的科學方程。
There is one very familiar formula. That is E=MC2. It says something about the creation of the universe. It says even if the universe is created just out of pure energy that because energy can be converted to matter and matter to energy. That you can get all of the stuff that we see in the universe from this pure energetic event.
E=MC2是人們很熟悉的質能方程，它說明了宇宙的誕生?？v使宇宙僅僅是由純粹的能量爆炸而來，那也是因為物質能量可以相互轉換。就是說我們看見的所有事物都誕生于這個能量爆炸事件。
Einstein's little equation had a big impact. It led to the first nuclear bombs. In a nuclear explosion, a small amount of matter is converted into an enormous amount of energy. As the universe was forming, the exact opposite happened. Pure energy transformed into particles of matter.
愛因斯坦的公式雖短，但影響力巨大。它催生了第一顆核炸彈。在核爆炸發生時，質量很小的物質被轉化成了巨大的能量。宇宙的形成卻恰恰相反，純粹的能量轉化成物質的分子。
You don't need to create matter in the beginning, you just need energy. And energy alone can lead to the creation of an entire universe.
最初需要的不是物質，而是能量。只要有能量就能創造出整個宇宙。
