In a strange reversal of the Big Bang,
在宇宙大爆炸的奇异倒转之中
space itself would contract.
空间会进行收缩
This theory is known as the Big Crunch.
这个理论叫做宇宙大挤压理论
In the end, if the theory is right,
如果理论是正确的，那么最后
in 30 billion years from now,
在距今三百万年之后的未来
all the matter of the universe would be swallowed by a single black hole.
宇宙中的所有物质都会被一个黑洞所吞没
The entire universe would exist as one tiny point,
整个宇宙将会变成一个小点
much as it was at the instant of the Big Bang.
和宇宙大爆炸发生时的大小差不多
But although that's a neat ending,
尽管这是个有道理的结局
I think that it's more likely
我却认为更加有可能的是
that dark energy will drive the expansion of the universe forever.
暗能量能使宇宙永远膨胀下去
And ultimately everything will just keep spreading out
最终一切都会继续扩散
until the universe is cold and dark.
直到宇宙变得冷却与黑暗为止
Everything will become so far apart
一切都会相距甚远
that even gravity will be defeated.
以至万有引力也将不再起作用
I think a big chill is what we have got in store,
宇宙冷却才是我们会遇到的结果
not a big crunch.
而不是宇宙大挤压
So will this be the end of us and life as we know it?
这就是我们与所有生命的终结吗
Or will we have figured out
或是在那之前
how to navigate through a new universe before then?
我们已经具备远航至其他宇宙的能力呢
I think we will only know when we truly understand
我想只有在我们完全了解宇宙起源后
why the universe exists at all.
才会知道问题的答案
Perhaps then when we finally unravel the whole cosmic puzzle,
或许当我们最终揭开宇宙谜题时
we will become masters,
我们就会成为主宰
not just of the universe,
不仅主宰我们的宇宙
but the universe next door.
也将主宰其他宇宙
