广义相对论预测了奇点
The general theory of relativity predicts the singularities.
……但同时宇宙还遵行另一套法则
... but the universe rules another set of rules.
量子力学
Quantum mechanics.
量子力学是我们对亚原子世界的描述，关于基本粒子，场和力以及它们相互的作用
Quantum mechanics is our description of the subatomic world Particles, fields, and fundamental forces and how they react.
量子力学指出，不存在无穷小或密度无穷大的物体
Quantum mechanics states that no The presence of something infinitesimally small or dense.
奇点不可能存在
The singularities cannot be present.
唯一性是一个很小的部分，所有的东西都是有限的，因为密度是有限的，引力也是有限的
Uniqueness is a small part where everything is finite because The densities are finite and the gravitational forces are finite.
这两种主宰我们存在的理论完全矛盾
It breaks all laws and becomes unreasonable.
量子力学的观点意味着，我们所理解的大爆♥炸♥不存在
The lack of uniqueness means no The presence of the Big Bang as we understand it.
那么我们的宇宙是如何起源的呢？
So how did our universe originate?
科学家们现在相信他们找到了答案
Scientists now believe they have the answer.
……一个与广义相对论和量子力学一致的解释
... a solution consistent with general relativity and quantum mechanics.
量子时空
Quantum spacetime.
成功的量子时空理论可以解答我们宇宙最初的瞬间发生了什么
Successful quantum spacetime theory answers Asked what had happened in the first moments of our universe.
我们希望经过修正的量子引力理论不包含任何奇点，我们将用其他东西取代大爆♥炸♥
We hope that the correct quantum theory of gravity does not contain Any singularity, we'll replace the Big Bang with something else.
如果我们知道另一个东西是什么，就会知道我们的宇宙是从何而来，以及是如何开始的
If we know what this other thing is, it will be lost We deduce how and why the universe began.
在量子时空的大爆♥炸♥中，不存在从虚无中爆发出来的奇点
In the Big Bang of quantum space There was no uniqueness that exploded out of nowhere.
相反，宇宙是从另一个垂死宇宙的残骸中产生的
Rather, the universe arose from the remains of another dying universe.
宇宙可能在大爆♥炸♥之前就存在空间和时间，宇宙不是膨胀而是收缩
A universe could exist before the Big Bang and space And a time, and instead of expanding the universe was shrinking.
宇宙可能并没有在大撕裂或冻结中结束
The universes may not have ended in rips or freezes.
也许是坍缩
Maybe it collapses.
一个古老的宇宙开始膨胀，他开始在引力作用下坍缩
An ancient universe then expanded He started to fall apart by his gravity.
然后把时空压缩到一个点上
To crush space-time to a point.
但时空并没有形成奇点，而是再次发生爆♥炸♥
But instead of being unique Space-time erupted again.
随着物质密度的增加，物质的收缩，这种力量会把一切都推了出去
When matter became more dense when it was crushed That force pushed everything out.
然后宇宙反弹并再次爆♥炸♥，引发新一轮膨胀和新一轮的大爆♥炸♥
Then the universe rebounds and explodes again on a tour New from expansion and new great explosion.
我们所理解的宇宙大爆♥炸♥就是这种反弹的产物
Understand that the Big Bang is the product of this bounce.
这个理论假设时空决定了我们今天的生活来自于古代宇宙的坍缩
This assumes that the spacetime decides on Our lives today came from the collapse of an ancient universe.
我们生活在无尽的时空生，死，重生循环中
And we live in an endless spacetime cycle of Birth, death, and rebirth.
我的时空是轮回的
The universe of my space is bouncing.
如果我们生活在轮回的宇宙中，那么人们普遍认为宇宙非常古老且无穷就合理了
If we live in a regression, then who is it? It is accepted that the universe is very ancient.
它经历了无穷无尽的反弹，没有一个绝对的开始
And he underwent an endless series of Bounces and no absolute start.
我们可能是宇宙生命中无限循环的重复
We may be a repetition of an infinite number Of cycles in the life of an essential universe.
我们很难理解时空
We hardly understand space-time.
也许我们永远无法彻底理解它
Perhaps we will not fully understand it.
但很明显，离开了时空，我们就不会在这里了
But it is clear that without Spacetime when we were here.
时空是一个真实的东西，它是基础体系的一部分
Space-time is a real thing, it is part of Basic architecture and furniture for reality.
要真正理解我们宇宙的最终命运，利用望远镜仔细地观察还不够
To understand the ultimate fate of our universe you will not It suffices to look only more closely at our approach.
相反，我们必须理解时空的基本性质
Rather, we must understand the fundamental nature of spacetime.
我认为我们从中得出的最大结论是宇宙是奇特的
I think the biggest thing we draw From all this is that the universe is strange.
很多人认为我们在吸毒，这是我们自己编出来的
Many believe we are taking Drugs make up that and make up it.
答案是我们是被迫变得这么疯狂的
The answer is that we are driven by this madness.
宇宙比我们想象的还要疯狂
The universe is more crazy than we imagined.
你现在生活在的这个宇宙，它的美丽和复杂的确远远超出了人类能够理解的范畴
You are now living in a former complex, beautiful universe More than the human mind can perceive.
