There is a 500 meter Aperture Spherical Telescope (fast) in Qiannan Buyi and Miao Autonomous Prefecture of Guizhou Province. In the eyes of Steve Hawking, a famous British physicist, he thinks that our “Chinese sky eye” is too large to be caught by the discovery of extraterrestrial life and “visit” the earth.
Therefore, he repeatedly warned: do not respond to any signals from outer space, because the other side has no clear intention, and do not take the initiative to contact them. If we expose the location of human beings in this way, and two civilizations of different levels meet, it will be an unimaginable catastrophe.
However, in recent years, our enthusiasm for exploring life has not diminished. For extraterrestrial life, the existence of signs of life on Mars has always been a hot issue. Scientists have launched dozens of space probes to Mars. From the images sent back by these probes, we have discovered some secrets of Mars.
On August 14, 2014, the curiosity Mars probe returned an image in which a stone with a peculiar shape appeared. Some netizens said that it looked like a human leg bone. Once the news came out, it caused a big stir. Does life really exist on Mars?
A NASA spokesman refuted the rumor and explained that the reason why the stone looks like a human thighbone is that it is caused by Mars weathering or water erosion and is formed by natural factors. And even if life ever existed on the surface of Mars, it could only be simple and tiny creatures like microbes.
As we all know, although Mars is also shrouded in the atmosphere, the main component of the Martian atmosphere is carbon dioxide, followed by nitrogen and argon, in addition to a small amount of oxygen and water vapor. There’s not enough oxygen to support the formation of complex life, so it can’t be a fossil.
Sharp eyed friends must have found the word “water erosion”. Yes, on July 25, 2018, scientists found a liquid water lake with a diameter of about 20 kilometers 1.5 kilometers under the Antarctic ice sheet of Mars. But at present, it is only the result of radar analysis, and it must be verified after landing on Mars in the later stage. However, the 1.5km thick ice sheet can not be dug, which is also very difficult.
To get back to the point, although NASA has come out to explain it, some people still firmly believe that this is the conclusive evidence of the existence of extraterrestrial life, perhaps the obsession of “not hitting the south wall, not looking back”. In this regard, someone has put forward a special idea. He wants to borrow the curiosity Rover from NASA in order to find life on Mars. He also says that if NASA is willing to lend the curiosity Rover to him, he will guarantee to find signs of life within a few months.
However, Xiaobian thinks that it’s good for us to take a look at the “bold words” released by this little friend. The technology industry specializes in searching for aliens, which should be left to competent scientists!
