导读:被誉为“我国天眼”的500米口径球面射电望远镜(FAST)近来正式敞开地外文明查找,寻觅来自国际深处高才智生命的信号。地外文明查找是FAST望远镜五大科学方针之一。

FAST is the biggest single-dish radio telescope in the world. ASIA NEWS

Are you curious of looking up at the stars and wondering if there’s intelligent life out there? So is Five-hundred-meter Aperture Spherical Telescope, China’s mega-science project and the world’s largest single-dish radio telescope.
仰视星空时你是否会感到猎奇,想知道星星上是否也存在着才智生命?我国严重科学工程、国际最大单口径射电望远镜500米口径球面射电望远镜(FAST)也想一探终究。

On April 28, FAST, nicknamed “China’s Eye of Heaven”, embarked on its search for extraterrestrial intelligence.
4月28日,被誉为“我国天眼”的FAST正式敞开地外文明查找。

As the news went viral on social networking sites, someone commented saying: “Do not answer! Do not answer! Do not Answer!”
这一新闻随即在交际媒体上引爆,有人谈论道:“不要回应!不要回应!不要回应!”

It seems that The Three-Body Problem, a science fiction novel by Chinese author Liu Cixin, has influenced minds so deeply that people are worried about the possibility of the Earth being invaded by an advanced extraterrestrial civilization.
看来我国作家刘慈欣所著的科幻小说《三体》适当家喻户晓,咱们都忧虑地球有或许遭到先进的地外文明侵略。

That worry is, at least for now, unnecessary. Of the 1,800 planets that have been discovered, less than 20 are capable of supporting life, and the nearest among them, Gliese 581, is 20.4 light-years away.
至少从现在来看,这种忧虑是不必要的。在人类发现的1800颗行星中,只要不到20颗具有供生命存在的条件,其间离地球最近的格利泽581在20.4光年之外。

According to Robin Hanson’s Great Filter theory, there is less than a one in a million chance of any extraterrestrial life form evolving into higher intelligence or a civilization. And since their distance from China could even be millions or billions of light-years away, if they travel at the speed of light, it would take them at least millions of years to reach us.
罗宾·汉森提出的“大过滤器”理论以为,任何地外生命要进化到高才智生命,乃至是一种田外文明,概率不到百万分之一。由于它们或许间隔我国数百万乃至数十亿光年,纵使它们以光速游览,也要花上至少数百万年才干抵达地球。

However, that does not mean FAST’s job is meaningless. As mankind’s most sensitive radio telescope, FAST can best collect signals from the universe. Researchers can distinguish even a 4 Hz difference in the signals received, meaning it can best distinguish between manmade and ET-made signals. Even the signals from a non-ET civilization are useful, because they might contain some hidden information leading to the discovery of new stars or planets.
但这并不意味着FAST的作业毫无意义。作为人类最活络的射电望远镜,FAST能够最大极限地搜集国际中的信号。研讨人员乃至能够完成频率分辩率4赫兹,意味着FAST能够最大极限地分辩人类与外星生物所宣布的信号。不是由地外文明宣布的信号也有用途,由于它们或许含有一些能发现新恒星或许新行星的躲藏信息。

With FAST joining the cause, mankind can browse the universe more deeply than ever before and increase knowledge about the universe. And whatever it achieves is the best evidence of China’s advanced technology in astronomy and the study of the universe.
推进FAST地外文明查找巡天,能够到达史无前例的深度,拓宽人类对国际的知道。不管获得何种效果,这都是我国先进的天文学技能和国际研讨的最佳表现。
