If realised, the idea could one day save Earth and the entire solar system from colliding with a supernova, or even allow our descendants to colonise other nearby stars.

倘若实现,这个想法将有一天可以拯救地球和整个太阳系,通过对超新星的撞击,或者甚至让我们的后代移民去其它的星系。

Dr. Matthew Caplan, an Illinois State University astrophysicist specialising in the interiors of neutron stars, has proposed a unique new variant of the stellar engine concept known as the ‘Caplan thruster', which would hypothetically be able to move our solar system through the Milky Way galaxy by harnessing the energy of our Sun.

在伊利诺斯州担任天体物理学教授的马修 卡普兰博士,专门从事于中子星内部的研究,他提出了一个独特的全新的关于星球能源的多样概念,这个概念被称为卡普兰推进器,这个推进器理论上可以通过利用太阳能将太阳系于银河星系中移动。

The astrophysicist's concept was featured in a .com/watch?v=v3y8AIEX_dU&feature=emb_title">recent video by Kurzgesagt, a German YouTube channel featuring educational content in animated form.

这个天文物理学家的概念被油管的一个德国频道做成了视频,这个频道主要以生动的形式介绍教育方面的内容。

The video, which went viral and has accumulated over 3.3 million views as of this writing, outlines in easy-to-understand layman's terms just how the ‘Caplan thruster' would work.

这个视频彻底火了,已经积累了超过3.3万观看量,源于这个视频的文案和主题让非专业人士可以了解到“卡普兰推进器”是怎样运作的。

Explaining why the stellar engine is needed in the first place, Kurzgesagt explains that at the present moment, “only the vast distances between objects protect us from the dangers out there. But we might get unlucky in the future. At some point, we could encounter a star going supernova, or a massive object passing by and showering Earth with asteroids."

为了解释为什么星球能源是至关重要的,这位德国油管博主解释说在最初,“只有非常遥远距离的物体保护我们防止遭受侵害。但是我们在未来可能就没有那么幸运了。在某个节点,我们可能会遇到一个星体变成超新星,或者大量物体经过并且对地球进行小行星簇射。”

At current levels of scientific knowledge, humanity is capable of predicting such events thousands if not millions of years in advance. However, actually doing something about it is another story, and that's where the stellar engine comes in.

在最初的科学知识领域,人类是可以预测这些类似的发生在千年以内的事件的,但是,实际上做这些事是另外一个故事了,并且那就是星球能源怎么产生的。

“How do we possibly move the hundreds of thousands of objects in the solar system? The good news is, we can ignore all of that. We only need to move the Sun. All the other stuff is glued to it by gravity, and will follow it wherever it decides to go,” Kurzgesagt explains.

“我们怎样可以在太阳系中移动成千上万个物体?好消息是,我们可以忽视这一切。我们只是需要移动太阳就好了。其他的一切事物都是会受到重心引力而移动的,并且会跟着太阳走,无论它去哪里。”Kurzgesagt 解释说。

How-To Guide to Moving Our Solar System

如何移动我们的太阳系

There are two “real physics certified” methods of moving the Sun –one being the Shkadov thruster, developed by Soviet scientist and aircraft engineer Leonid Shkadov in the 1980s. This method proposes the construction of a giant, lightweight parabola-shaped mirror created from micro-reflecting aluminium foil placed over one of the Sun's poles to reflect solar radiation and thus create thrust.

这里有两个“真实物理证明”移动太阳方法——一个是被苏维埃科学家和航空工程师雷诺 沙卡基在1980年代发明的沙卡基推进器。这个方法提出了一个结构巨大的,平均重量以下的抛物线型的镜子,用来创造微波铝板放置在太阳极点之前,来反射太阳辐射,以此来产生推进力。

“At full throttle, the solar system could probably be moved by about 100 light years over 230 million years. Over a few billion years, it gives us near complete control over the Sun's orbit in the galaxy. But in the short term, this might not be fast enough to dodge a deadly supernova,” Kurzgesagt warns.

“在完全的节流下,太阳系很有可能在230万年里被移动大约100光年,在这上千万年里,太阳系给了我们在星系中几乎完全的太阳轨道控制能力。但是在短时期内,这可能并不能够足够快到去闪避一个将死的超新星。”K 警告到。

One alternative, created by Dr. Caplan, and published in the December 2019 issue of peer-reviewed journal Acta Astronautica, is predicated on a different concept – a rocket-like space station platform which uses material from our Sun to power nuclear fusion.

另外一个选择,即卡普兰博士在2019年12月创立的关于同行领域研究的太空航行的问题,被推测为在一个完全不同的概念——一个类似于火箭的太空站平台,用来利用来自太阳能原子核聚变的材料。

The Caplan thruster consists of two jets – an oxygen jet shooting energy away from the Sun, while a second jet of high energy matter “pushes the Sun like a tugboat” and prevents the thruster from crashing into the Sun and being consumed.

卡普兰推进器由两个喷气器组成,一个氧气喷气器,将能量推进原理太阳,而第二个喷气器会利用高能量“像一个拖船一样推动太阳”并且组织推进器跟太阳相撞然后被吞噬。

In theory, the device would harvest hydrogen and helium from solar wind close to the Sun, with these materials burned in fusion reactors while a Dyson sphere surrounding the star was focused to increase the heat generated at the extraction point, enabling billions of tonnes of mass to be safely lifted off the Sun and into the thruster.

理论上,这个设备会在接近太阳的太阳云层中吸收氢和氦,这些材料会在核聚变反应中燃烧,同时围绕在星体周围的戴森星体会增加在抽出物点附近产生的热量,让千百万物体安全的飞离太阳然后进入推进器里。

Dr. Caplan estimates that the engine could move the solar system by 50 light years in a million years' time. “At full throttle, the solar system can be completely redirected in its galactic orbit in ten million years,” Kurzgesagt notes.

卡普兰博士估测,这些能量会让太阳系在一万年的时间里移动五十光年。“在完全的节流下,太阳系在十万年后的的星系轨道可以完全重新传入,”K 说。

And saving life in our solar system isn't the thruster's only potential benefit. “With a Caplan thruster, we can turn our entire solar system into our space ship, for example by orbiting backwards in the galaxy and colonizing hundreds or thousands of stars as we pass by them,” the channel says.

拯救太阳系中的生命并不是推进器潜在的唯一好处。“通过卡普兰推进器,我们可以将整个太阳系装进我们的太空舱里,例如星系的逆行轨道和当我们经过这些移民而来的上千万星体,”这个频道如是说。

In other words, in the long- long- long-term (millions or even billions of years) Dr. Caplan's variant of the stellar engine may very well not only save humanity, but enhance its chances of continuing to exist long after our Sun burns out and turns into a red giant, some 4-5 billion years from now.

一言概之,在很长很长的时期(百亿年间)卡普兰博士的多样的星体能源不仅可以很好的拯救人类,而且可以提高我们生存的几率,在太阳自我燃烧毁灭然后变成红色球体之后,距今大概还有4到5万年的时间。
