- Here is an image.
- 这是一张照片。
- Since galaxy clusters are representative slices of the universe, scaled-down versions.
- 因为星团可以看做是宇宙的缩小版。
- They are mostly made up of dark matter,
- 它们也是大部分由暗物质构成,
- and that's what you see in this bluish purple.
- 这就是你看到的偏蓝的紫色。
- The red represents the hot gas,
- 红色代表高温气体,
- and, of course, you can see many galaxies.
- 当然,你可以看到很多星系。
- What's happened is a particle accelerator at a huge, huge scale.
- 发生的事情就是一个非常巨大版本的粒子加速器。
- And this is very important,
- 这很重要,
- because what it means is that very, very small effects that might be difficult to detect in the lab,
- 因为这意味着,在实验室里某些因为太小而很难检测到的效果,
- might be compounded and compounded into something that we could possibly observe in nature.
- 可能因为不断的叠加,而让我们在自然界观测到。
- So, it's very funny.
- 这很好玩。
- The reason why galaxy clusters can teach us about dark matter,
- 为什么星团可以教我们暗物质的知识,
- the reason why galaxy clusters can teach us about the physics of the very small,
- 为什么它们可以教我们关于“极小”的物理,
- is precisely because they are so very big.
- 其原因就是因为它们太大了。
- Fourth thing: the physics of the very strange.
- 第四个问题:关于“非常奇怪”的物理学。
- Certainly what I've said so far is crazy.
- 我刚才所说的已经很疯狂了。
- Okay, if there's anything stranger I think it has to be dark energy.
- 但是,如果有比那些更疯狂的,我认为就是暗能量了。
- If I throw a ball into the air,
- 如果我把一个球扔向空中,
- I expect it to go up.
- 我预计它将上升。
- What I don't expect is that it go up at an ever-increasing rate.
- 而我不会预计它以越来越快的速度上升。
- Similarly, cosmologists understand why the universe is expanding.
- 同样的,宇宙学家理解为什么宇宙在膨胀。
- They don't understand why it's expanding at an ever-increasing rate.
- 他们不理解的是,为什么宇宙膨胀的速度越来越快。
- They give the cause of this accelerated expansion a name,
- 他们为加速膨胀的原因取了个名字,
- and they call it dark energy.
- 叫做暗能量。
- And, again, we want to learn more about it.
- 同样,我们希望对它了解更多。
- So, one particular question that we have is,
- 其中一个问题是,
- how does dark energy affect the universe at the largest scales?
- 暗能量是如何在极大的尺度上影响宇宙的?
- Depending on how strong it is,
- 取决于能量的强弱,
- maybe structure forms faster or slower.
- 或许结构的形成会有快有慢。
- Well, the problem with the large-scale structure of the universe is that it's horribly complicated.
- 但是对于宇宙的大尺度结构,问题是它复杂得可怕。
