Why did Hawking repeatedly advise China to close the Eye of Heaven before his death?

Our China? Eye of the sky? Is it a radio telescope, English name FAST, a telescope with a diameter of 500 meters? Heaven? . With a total reflection area of 250,000 square meters, scientists can observe the known edge of the universe and receive very weak signals from the universe.

The purpose of scientific research is twofold:

Observations have found pulsars in the universe. To put it bluntly, the earth, as a small dust floating in the universe, wants to lock its own cosmic coordinates by locating pulsars. Looking for neutral hydrogen. If there is neutral hydrogen, it is possible to find another planet suitable for human habitation. Hawking, as one of the cosmophysicists who firmly believe in the existence of aliens, opposes? Eye of the sky? Construction, probably because: the earth and even the Milky Way are remote areas of the universe. The current living conditions of mankind are very comfortable and safe. Compared with the whole universe, the Milky Way is small and simple. With our present scientific knowledge and cognition, it is impossible to see the whole universe. We don't know how much danger there is outside the galaxy. We explored the universe? Small? Movement may also expose the earth to unknown space.

However, Tian Yan, built at 20 16, is the largest single radio telescope in the world. At present, more than 50 pulsars have been discovered. Old Hawking said, how can our curiosity about the universe stagnate? Moreover, the Nobel Prize competition is so fierce that it is not as good as a radio telescope. Eyes? Astronomical scientists will go blind.

Dark forest? Rule = Shoot the first bird. In Liu Cihang's novel Three-body? Dark forest? The law describes the universe as a huge dark forest, and human beings, threesomes and even other creatures in the universe live in the depths of the universe. Once someone exposes his position, others will collectively shoot for their own safety, killing the exposed people, and the forest will be calm and everyone will get along well. Translate into Chinese? Blow a bird's head off? .

In "Three-body", an earthman died and contacted aliens actively, exposing the position of the earth. Here comes the trio. We can't fight it, we can only. Feeding? , all kinds of bad intentions. Of course, the trio was almost extinct because of exposure.

In 200 1 A Space Odyssey, there is a stargate, an alien? Sower? Through it, we can cross the galaxy and spread civilization. Even our ancestors? Moongazer? It is also through its training and enlightenment. Later, the man flew the aircraft through the stargate, only to find that two years ago, after the stargate was dug up on the moon, human beings were monitored.

Not the whole novel? Sower? Images, but just imagination, are scary enough. It knows everything, and its means, we can't even guess. That man was later dismantled by it? Son of a star? , is another kind of wisdom. But, as a person, he is really dead!

Science fiction belongs to science fiction. What exists objectively does not depend on our will. Science fiction is really amazing. Judging from the current knowledge, some novel plots have really affected human reality. "200 1 Space Roaming" has influenced many scientists of NASA. Nautilus in Two Wan Li Under the Sea is like predicting a nuclear submarine.

For the unknown, we always think before we do it. With the upgrade of tools, you can do more things that you couldn't do before. Just like in ancient times, we didn't even know about fire, so we were afraid of it, but it was a good thing. When we understand and learn to use it, we will move towards civilization.

I personally support Tian Yan in observing the world with an objective eye and discovering and exploring the universe. We never like making trouble, but we are not afraid when things come. Science and technology, to strive for the first place, don't give up easily because of what others have said.
