在大爆炸的最初几分钟内，宇宙是种温度极高且非常小的物质。
During the first few moments of the big bang, the universe was an extremely hot and very small matter.
所以在大爆炸的最初几分钟内，宇宙是种温度极高且非常小的物质。
So during the first few moments of the big bang, the universe was an extremely hot and very small matter.
正如宇宙大爆炸一样，我们在一个小空间里面有巨大的能量。
Just like the Big Bang, we have huge energy in a small space.
如果宇宙中的所有粒子都是无质量，那么宇宙对于他们就会是初始时那样无限小，并且无限小的宇宙会经历一次大爆炸。
If all particles in the universe were massless, then, the universe would look to them to be infinitely small. And an infinitely small universe is one that would undergo a Big Bang.
在大爆炸理论里，早期宇宙的状态是一个奇点，这意味着宇宙曾经是无穷小的。
In Big Bang theory, the state of the Universe is a singularity in early times, meaning that the Universe was once infinitely small.
而一个无穷小的宇宙便会经历一场大爆炸。
And an infinitely small universe is one that would undergo a Big Bang.
首先，理论上的大爆炸使得宇宙演化开来。几十亿年过去之后，我们的太阳系诞生于小爆炸。
First there was the theoretical Big Bang that got the universe going. Several billion years passed. Then a Little Bang birthed our solar system.
如果这种小的热点正如所期望的那样，对于另一个科学观点来说将是一个胜利，这个科学观点被称为宇宙膨胀理论，是对宇宙大爆炸理论的改进。
If the small hot spots look as expected, that will be a triumph for yet another scientific idea, a refinement of the Big Bang called the inflationary universe theory.
如果这种小的热点正如所期望的那样，对于另一个科学观点来说将是一个胜利，这个科学观点被称为宇宙膨胀理论，是对宇宙大爆炸理论的改进。
If the small hot spots look as expected, that will be a triumph for yet another scientific idea, a refinement of the Big Bang called the inflationary universe theory.
