这些观测结果构成了现在被我们称为大爆炸理论的证据。

According to this theory, all matter in the universe was once a singular, infinitely dense particle.

根据这一理论，宇宙中的所有物质较初都源于一个密度无限高的单一粒子。

In a sense, our piece of the universe was once at the center.

从某种意义上说，我们所在的这部分宇宙曾处在中心。

But this theory eliminates the whole idea of a center since there can't be a center to an infinite universe.

但这个理论排除了”宇宙中心”的想法，因为无限宇宙根本没法有中心。

The Big Bang wasn't just an explosion in space; it was an explosion of space.

大爆炸并不只是在空间的一次爆炸，而是空间本身的爆炸。
