To get your head rumished,let's return to that idea that the.
为了让大家了解 我们再来回顾这种讲法
strings of string theory unlike notes played by a string quartet.
弦理论的弦就像 四重奏演奏的音符一样
Each vibration of the strings gives rise to the fundamental particles and to the forces of nature.
弦每次振动都会 产生基本粒子和自然力
which between them,make up everything in the universe.
两者结合后进一步生成宇宙万物
But of course,the quartet could just as well be playing a different tune.
当然 四重奏可以用不同的振动音符来
with different vibrating notes.And mathematically,that different tune.
演奏不同的弦乐 从数学的角度看 不同的旋律
would produce different particles and different forces of nature.
会产生不同的粒子和自然力
Meaning,a different universe.Change again,and that's another universe.
也就是不同的宇宙 再变又会产生另一个宇宙
So just as there are an endless number of possible tunes,
所以正因为是没完没了 数之不尽的
so our universe must be just.one of billions of universes.
因此人类的宇宙必定 只是几十亿个宇宙之一
We can't see them because they are beyond the limits.of our own universe.
我们无法看见 因为它们已超出极限 人类宇宙
Each with their own history and properties.
每个宇宙都有各自的历史和特性
Some are unstable and collapse back to where they came from.
有些因不稳定而又崩毁回复原装
Some will produce no stars or planets and so be dark and cold.
有些并未生成恒星或行星 因此既阴暗又寒冷
Others will expand and go on to produce stars and galaxies.like ours.
有些则会膨胀 不断生成恒星和星系 类似我们的
As we pounder mist,we should not be surprised.
思索这个问题时 我们不需感到意外
to find ourselves in a universe that is perfect for us.
人类身处的完美宇宙 因为人类可以生存,
Our very presence means our universe must be just right.
表示我们的宇宙正好合适
So the search for the key to the universe.
因此探索宇宙的关键
has had one unexpected result:We have found the key to every other universe,too.
已有意外的收获 我们同时发现了其它宇宙的关键
It seems that M-theory is a system of laws that governs everything:The Grand Design.
M理论似乎是支配万物的一套定律 也就是大设计
