So, the old control room. I haven't been here for years!
這里是老的控制室。這些年，我不在這里！
So what this picture tells us... it's called event display.
那么，這個圖象告訴我們……所謂的事件顯示。
The height of these bars is how much energy is released in this collision in that particular direction.
這些線條的高度是在這次碰撞中所釋放的能量的量，在特定的方向上的。
There's a collision in the middle, and the stuff's spraying out.
這是個中等的碰撞，物體在噴出來。
So，what we're trying to do is to sum all this energy, to see if something is missing.
因此，我們正在統計所有的能量來觀察是否有什么消失。
If you look at this display, you see a lot of energy going in this direction,
如果你注意這個顯示，你會看到大量的能量在往這個方向跑，
but very little on the other side, and this yellow bar,
但是有很少的往另外一個方向，是這個黃色的線條，
in fact, represents the fraction of energy which is missing.
事實上，這部分就是消失的能量。
All right. So if you see that, that means that something escaped. That's right.
好了。所以你看到了的話，就意味著有東西流失了。對極了。
If gravitons ARE created, Greg believes the reason why they would disappear
如果引力子產生的話，格雷格認為它們為什么會消失的原因，
is because they vanish into a place beyond our reality, into some sort of extra dimension.
是因為它們消失到的地方超越了我們的現實，進入到了某些額外的維。
Now, we're all familiar with the three dimensions of our world,
現在，我們都熟悉了我們的三維世界，
there's up and down and north and south and east and west.
即上下、南北、和東西。
But what scientists like Greg are proposing is that there can be extra hidden, unseen dimensions.
但是格雷格這樣的科學家正提出可能存在著額外的、難以發現的、無形的維。
It sounds ridiculous, and it IS impossible to picture,
這聽起來很荒謬，真是不可能想象的，
but theoretically, it's possible,
然而在理論上，它卻是可能的，
and it's also possible that gravitons, the particles of gravity,
同樣可能的是引力子，引力的粒子，
can spend most of their time in those extra dimensions.
可能在那些額外的維里度過它們大部分的時間。
If gravitons really are created, and they escape in these extra dimensions, you would never see them.
如果引力子真的存在，它們泄漏到了這些額外的維里，你就永遠看不到它們了。
So although it might sound like a very odd hypothesis and odd concept,
所以盡管聽起來象是個非常古怪的假設，非常古怪的概念，
really, nothing prevents us of thinking in this direction,
實際上，沒有什么能阻止我們往這個方向去想，
especially if we can solve these mysteries.
尤其是我們有可能會解決這些迷團。
The graviton may really be the final piece in the puzzle.
引力子可能真的是迷團的最后一部分了。
