反物质是什么?

What is Antimatter?

我们所知道的一切都是由一些微小的粒子组成的
Everything we know is made of just a few tiny particles,
而每一种粒子都有一个邪恶的孪生体——反粒子
and every particle has a sort of evil twin – an antiparticle.
反物质是物质的镜像
So antimatter is a sort of mirror image of matter.
事实上 它们几乎是彼此的完美映射
In fact, they are almost perfect reflections of each other.
但这带来了一些问题
But this poses a bit of a problem.
从布莱恩·考克斯的电视节目中我们都知道
As we all know from watching Brian Cox on telly,
宇宙始于大爆炸
the universe began with the Big Bang,
因为这种对称性
and because of this symmetry,
物质和反物质应该是等量的
matter and antimatter should be made in equal quantities.
我们也从丹·布朗的书中知道
And as we also know from reading Dan Brown,
当物质和反物质相遇时
when matter and antimatter meet,
它们会在瞬间湮灭
they annihilate in a violent flash.
这意味着物质和反物质应该完全相互湮灭
This means the matter and antimatter should totally obliterate each other,
就在大爆炸后
just after the Big Bang,
只留下一个寒冷 黑暗 没有生命的宇宙
leaving a cold, dark, and lifeless universe.
所以我们的存在是一个谜
So the fact that we exist at all is a bit of a puzzle.
我们现在认为 物质和反物质之间的对称性一定存在某种微小的缺陷
We now think there must be some tiny flaw in the symmetry between matter and antimatter
这使得十亿分之一的粒子在大爆炸中存活下来
that allowed one particle in every billion to survive the Big Bang.
这些微小的残留物足以创造整个宇宙
This tiny leftover was enough to create the entire universe.
在欧洲核子研究中心 大型强子对撞机实验正试图揭开这个谜团
Here at CERN the LHC be experiment is trying to unpick this mistery,
弄清楚为什么我们没有在世界之初全部被消灭
and figure out why we weren’t all annihilated at the dawn of time.
