A Chinese supercomputer has created the largest ever digital version of the cosmos.

一台中国的超级计算机创造了最大的数字化模拟宇宙。

Sunway TaihuLight the world's fastest computer has modelled the birth and early expansion of the universe using 10 trillion digital particles a new report claims.

据他们的一份报告声称：这台名叫“神威太湖一号”的世界最快电脑，用十万亿个数字粒子模拟出了宇宙的诞生和早期的膨胀。

The supercomputer modelled these particles interacting with one another using quadrillions of calculations per second to model the cosmos.

这台超级计算机利用每秒千万亿次级（10的15次方）的模拟粒子间的相互作用，进而模拟出宇宙。

In astronomy researchers simulate the universe by breaking down its mass into particles.

天文学研究中，天文学家通过将质量分解为粒子的办法来模拟宇宙。

These particles interact with one another through physical forces such as gravity.

这些粒子通过如重力等物理力而相互作用。

A supercomputer can simulate these interactions using quadrillions of calculations per second.

超级计算机可以用每秒千万亿次级的计算来模拟这些力的相互作用。

The more particles are involved in the simulation the more precisely the scientists can replay and forecast the universe's evolution.

参与模拟的粒子越多，科学家就能越精确的重现和预测宇宙的进化。

This process can shed light on many issues such as the nature and spread of dark energy.

这一过程可以解释许多问题，比如暗能量的属性和传播方式。

With a simulation comprising 10 trillion particles the Sunway TaihuLight supercomputer created the largest ever model of the cosmos.

通过这个由十万亿个粒子组成的模拟，“神威太湖一号”创造了世界上最大的宇宙模型。

According to the South China Morning Post the machine simulated the cosmos by breaking it's mass down into trillions of particles.

It used 10 million CPU cores to create its version of the universe - known as N-body simulation.

它使用一千万个CPU内核来创建他们的数字化宇宙，也就是所谓的N体模拟法

The work was completed by the National Supercomputer Centre in Wuxi and involved computer scientists from the Chinese Academy of Sciences in Beijing. 

这项工作由位于无锡的国家超级计算机中心和北京中科院的科学家们协作完成。

'This is just a warm-up exercise' Professor Liang Gao chair scientist of the computational cosmology group at the National Astronomical Observatories said.

“这才仅仅是个热身”中科院国家天文台数值宇宙组首席科学家高亮教授说如是。

'We just got to the point of tens of millions of years after the Big Bang

“我们仅仅达到了宇宙大爆炸后的数千万年的时间。”

'It was still a very young stage for the universe - most galaxies were not even born.'

“这依旧是宇宙认知中非常浅薄的一层，大多数星系甚至都没有诞生”

Professor Gao said that the universe his team created is five times larger than any previous attempts.

高教授表示，他的团队所建立的宇宙模型是之前任何一个的五倍大

But while China's simulation was sustained for an hour a European model created in June which was the previous biggest attempt lasted for 80 hours.

尽管中国的模拟持续一个小时，但在早前6月份时，欧洲的最大的一次尝试达到了80个小时。

Academics from the University of Zurich recreated a simulation of 25 billion virtual galaxies which were generated from two trillion digital particles.

苏黎世大学的学者们重建了对250亿个虚拟星系的模拟，这些星系是由2万亿个数字粒子产生的。

'The challenge of this simulation was to model galaxies as small as one tenth of the Milky Way in a volume as large as our entire observable Universe' the researchers said at the time.

当时，研究人员声称，这项模拟的挑战在于，在和我们可观测的宇宙等大的体积重，银河系的体积只有十分之一

The Sunway TaihuLight achieves 93 Pflops on the Linpack benchmark and has a peak performance of 125 Pflops.

神威太湖一号在linpack的基准上达到了93Pflops，甚至峰值性能达到125.（LINPACK是线性系统软件包(Linear system package) 的缩写 ，PFLOPS是 pate floating point operations per second每秒所执行的浮点运算次数，每秒千万亿次）

This means it can run quadrillions of calculations per second.

这意味着它可以每秒进行千万亿次级的运算。

It is the fastest supercomputer in the world and marks the first time China has achieved this feat without the use of US technology.

这是世界上最快的超级计算机，也标志着中国头一回在不使用美国技术的前提下完成这一壮举。

Systems of this kind are used for weather forecasting designing nuclear weapons analyzing oilfields and other specialized purposes.

这个系统可以用来预测天气、设计核武器、分析油田和其他目的。

The supercomputer may be used to conduct earth system modelling ocean surface wave modelling atomistic simulation and phase-field simulation. 

这台超级计算机或许会被用做地球系统的模拟，海洋表面波模拟，原子模拟以及相场模拟。

"it's mass" does not make sense. You mean "its mass". "it's" = "it is" or "it has". Please try to remember. Together we can beat this. 

"it's mass"是无意义的，你指的应该是"its mass"，"it's" = "it is" 或者 "it has"，请记好. 团结起来我们就能赢.

The West spends trillions on 'entitlements' while others spend on R&D. We've lost our way with no sign of recovery.

当西方在福利上花费了数万亿的同时，其他地区把钱花在研发上，我们已经迷失了方向，找不回了

Hang on a second... tens of millions of years? I've got a book that says god did it in less than a week... surely the scientists and massive computer have got something horribly wrong? 

等等..千万年?? 我有一本书，上面说上帝创造世界只花了不到一周，一定是科学家和超级计算机出现了很严重的错误

This is false news. We Americans have the biggest and fastest and most expensive of everything including computers. 

荒谬！世界上所有的一切中，最庞大，最快速，最昂贵的必须属于我们美国人，包括计算机.

Ryant Freeman -> AngloAmerican
Fake news absolutely. It's impossible that Chinese built the world's most powerful super computer. They stole it from America and Japan. 

明显是忽悠人的，中国人搞不定世界上最强大的超级计算机，他们从美国和日本偷来的

Millomite -> AngloAmerican
I think that's called believing your own propaganda isn't it?

我猜这就叫迷之自信，对不对?
