The videos I watched became popular in ancient times

Chapter 305 China’s Sky Eye
Perhaps it was the appearance of airplanes that shocked ancient people from all dynasties.

So long after Su Chen introduced Beijing Daxing International Airport, everyone still didn't come back to their senses.

Su Chen was not in a hurry, so that everyone could digest and absorb it slowly.

After all, compared to the ancients, airplanes are indeed too shocking, and it takes time to adjust your mentality.

After a while, Qin Shihuang was the first to break the tranquility.

Ying Zheng: Anchor, I am very interested in this airplane. I wonder if the anchor can show you how to fly on an airplane?

The footage in the video was limited, and he wanted to know what the entire process of passengers taking a plane was like.

After Ying Zheng spoke, the emperors of other dynasties also spoke one after another, all expressing the same meaning.

Seeing that everyone was curious, Su Chen agreed without much thought.

"There will be a holiday soon. When the anchor takes a plane to go out for fun, he can start a live broadcast to let everyone see it."

Astrophysics, space astronomy, atomic nuclei, gravitational radiation.

"In the era without China's Sky Eye, it is difficult to imagine the working environment of our astronomers."

"Scientists can study microscopic technologies such as atomic nuclei and gravitational radiation by observing the movement of celestial bodies, which can promote the progress of basic science."

Thinking about the instruments he used to study astronomy, and then looking at the celestial eyes used by later generations, he couldn't help but be envious.

“It’s worth mentioning that the person who experimentally proved Einstein’s theory of relativity was an astronomer.”

"In short, the universe is like a natural laboratory."

"So with the Chinese Sky Eye, we can study some cutting-edge technologies."

"Putting aside the live broadcast for now, the host will introduce a super project to you. I believe some astronomy bigwigs from various dynasties will be very interested."

"In other words, we were pretty much locked into astronomy at that time."

The gap was so huge that he was deeply shocked.

The diameter reaches 500 meters, which is so huge and incredible.

"So if we want to break through this shackles, China must have a giant radio telescope of its own."

Especially the astronomers from all dynasties, their eyes were full of excitement and they were very energetic.

"Even if you borrow it, if you can observe it for an hour, everyone will be very happy."

If he had known more detailed knowledge of astronomy, he would have died with no regrets.

He specializes in astronomy, so he naturally understands the importance of having good equipment.

"Chinese scientists who want to conduct space observations of ultra-distant galaxies must borrow astronomical telescopes from other countries."

"And it is the most sensitive radio telescope in the world. It is made up of 4450 triangular aluminum alloy panels."

As soon as Su Chen finished speaking, ancient people from all dynasties were extremely curious.

"To put it simply, the Chinese Sky Eye can observe the universe from different angles."

“Don’t think that astronomy is just about looking up at the stars.”

Although he didn't know what these words meant, he also knew that later generations' research on astronomy had reached an extremely advanced level.

He couldn't even imagine that it would cover such a huge area.

In addition to the shock brought to him by the huge eye, he also noticed something, and that was some specific words spoken by the anchor.

Looking at the Chinese Sky Eye in the video played by the anchor, he was shocked and swallowed subconsciously.

As expected, this super project must be about astronomy.

"Because at that time, China was simply unable to participate in mainstream astronomical research."

Just through such a huge Chinese Sky Eye, he could know how exaggerated the research on astronomy was by later generations.

With the anchor's guarantee, Ying Zheng and others felt relieved.

"And this telescope took 22 years to build. Its name is China Sky Eye."

It would be great if he could also have equipment like the Sky Eye to study astronomy, which would surely reveal more truths about the universe.

"It's like a human eye, it can be turned around."

"Now, the anchor will tell you about the most important weapon of the country, China's Sky Eye."

"Coincidentally, in 1994, astronomer Nan Rendong conceived a giant radio telescope that could capture electromagnetic signals 137 billion light-years away."

Zhang Heng: Is this the astronomical super project that the anchor mentioned? Such a huge eye in the sky is really a super project.

But he also knew that this was just wishful thinking, and it was impossible in this life.

"This allows scientists to adjust the position of the reflector to focus the received signal."

"So if astronomy is locked up and we want to develop basic science, it will definitely be even more difficult."

"If others don't lend it to you, there's nothing you can do about it."

"Because there are many branches in astronomy, such as astrophysics, space astronomy, cosmochemistry, etc., and these branches will affect the progress of basic science."

"The China Sky Eye is the world's largest radio telescope, with an aperture of 500 meters and an area almost as large as 30 football fields."

“The scientific goals of China Sky Eye are mainly to do two things.”

"The first thing is to draw a space map and look for alien civilization."

"The second thing is to promote the progress of basic scientific theories."

"In the future, Earth's civilization will definitely move out of the Milky Way."

"But humans can no longer use a compass when conducting interstellar navigation, because the compass will not work if it is separated from the earth's magnetic field."

"Then at this time, we need pulsars for positioning."

"The so-called pulsar is like a lighthouse, it will illuminate the surroundings regularly."

"Scientists use the period of the pulsar's illumination toward the Earth to deduce its position."

"The more pulsars we find, the more precise our map of the stars will be."

"When humans navigate the space in the future, they will be able to use pulsars to locate their current location."

"So far, China's Sky Eye has found 132 pulsars, which has undoubtedly made a huge contribution to human spaceflight."

"In September 2020, China's Sky Eye is expected to officially launch its exploration of extraterrestrial civilizations."

"To put it simply, we are going to find aliens. Maybe we are not alone."

"Let's talk about the second thing, the basic scientific theory of China's Sky Eye research."

"Don't underestimate the basic theory. The atomic bomb was invented because physics broke through the basic theory."

“Once Newton’s classical mechanics and Maxwell’s electromagnetism together dominated physical research.”

"At that time, many scientists believed that the Daxia of physics had already been established, and future scientists would only need to make measurements and calculate data."

"But the physics at that time could not explain the phenomenon of black body radiation, so the new generation of scientists like Einstein studied a new physical system from another angle, now called quantum mechanics."

"The success of quantum mechanics is equivalent to knocking classical mechanics off the altar. Of course, this is not a bad thing."

"It is precisely because of the emergence of quantum mechanics that the basic theories of physics have been broken through."

"In other words, the physics at that time was upgraded from classical mechanics to quantum mechanics."

"With the advent of quantum mechanics, human technology has also advanced by leaps and bounds."

"The lasers, atomic bombs, computers, etc. that we know now are all products designed based on quantum mechanics. This is the power of breakthroughs in basic theory."

Ying Zheng: The aliens mentioned by the anchor should refer to creatures living on other stars.

Speaking of aliens, when he was a child, he also imagined whether there were immortals on the stars.

After all, in some myths and legends he knew, there were indeed immortals living on the stars, and they should be aliens.

But as he learned more and more about future generations, he discovered that there were no gods or ghosts in this world, and there were no immortals even on the stars.

But according to what the anchor says now, future generations have been working on finding aliens.

The movie "The Wandering Earth" he watched before had mentions of aliens.

This made him realize that future generations would believe in the existence of aliens, otherwise they would not spend so much energy searching for them.

Moreover, the existence of the Sky Eye is also to find traces of the existence of aliens.

Perhaps, there really are aliens in the distant stars.

He subconsciously looked up at the night sky, staring at the stars one after another, and his mind was filled with thoughts. "But in quantum mechanics, there is also a problem that has not been overcome, and that is the uncertainty principle."

"To put it simply, you cannot measure the position and speed of a particle at the same time."

"Afterwards, many physicists explained this phenomenon with their own understandings, but Einstein did not agree with their explanations until his death."

"Not only Einstein, but also scientists who studied atomic bombs have said that no one really understands quantum mechanics."

"His words can prove that there is still a lot of room for development in basic science."

"If any country can achieve major breakthroughs in basic science, it can lead the world in developing new technologies."

"Astronomy is a very important means to make breakthroughs in basic science."

"Many major theoretical breakthroughs are achieved through astronomy. At this time, China's Sky Eye plays a crucial role."

"For example, our scientists are likely to use the Chinese Sky Eye to decipher the mystery of dark matter in the future."

"Einstein's gravitational lensing tells us that massive objects cause space-time to curve."

"In astronomical observations, humans have discovered that a lot of light is bent."

"Wherever light bends, there must be a very large amount of matter. This matter is what we call dark matter."

"Now that scientists know the location of dark matter, they can then study the properties of dark matter through the spectral line velocity and flux distribution of neutral hydrogen and carbon monoxide."

"If the code of dark matter is cracked, it will be a major breakthrough in our basic science."

"In other words, the classical mechanics of the past can be upgraded to quantum mechanics, and quantum mechanics can also be upgraded to a new kind of physics in the future."

"At that time, human technology will naturally reach a higher level, and maybe all the scenes in science fiction movies will be realized in the future."

"If we study dark matter thoroughly, humans will be able to achieve interstellar travel."

"You know, the biggest difficulty in interstellar travel now is the fuel problem."

"Almost 90% of the weight of an ordinary launch vehicle is fuel. If we use the current technology to achieve interstellar level navigation, it is really a pipe dream."

"But in the future, if we achieve breakthroughs in basic science."

"Dark matter can be converted into energy, which solves the fuel problem for interstellar navigation."

"Because 85% of the matter in the universe is dark matter."

"This quantity is equivalent to inexhaustible supply."

"At that time, the entire universe will become a refueling station for spacecraft."

"If the spacecraft is out of fuel, add some dark matter."

"From an earth perspective, we no longer have to worry about energy."

"We don't have enough energy. Go grab some dark matter from the universe and bring it back. You'll have everything."

Li Shimin: If the anchor hadn't told me, I wouldn't have known that astronomical research was so important.

The Tang Dynasty had a Qin Tianjian who specialized in the study of astronomy, and they took it very seriously.

After all, astronomy is related to the calendar. Only by understanding the laws of the movement of celestial bodies can an accurate calendar be promulgated.

With an accurate calendar, people's agricultural production can be foolproof.

That's the extent of his emphasis on astronomy.

And now the anchor told him that the importance of astronomy is related to the prosperity of a country.

Breakthroughs in basic science are all based on astronomy, and breakthroughs in basic science can greatly promote the progress of science and technology.

When technology advances to a certain level, interstellar travel will not be a problem.

Traveling in the starry sky in a spaceship made his blood boil just thinking about it.

After all, everyone wants to explore the mysterious starry sky, and he is no exception.

To do all this, we must return to the study of astronomy.

As long as astronomical knowledge is thoroughly studied, human science and technology will achieve a great explosion, thus realizing scenarios that were previously unimaginable.

Only then did he finally understand why future generations wanted to build a huge eye in the sky.

When studying astronomy, instruments are crucial, and the Sky Eye is undoubtedly the most powerful astronomical instrument.

"With the advancement of basic science and technology, maybe humans can create wormholes."

"To briefly talk about the principle of wormholes, you can imagine that there is a mountain in front of you."

"If you want to cross from point A to point B of the mountain, you must climb the mountain."

"But if you dig a tunnel directly, you can easily go from point A to point B."

"The principle of wormholes is the same. It is equivalent to folding space."

"Normally, it takes us 10 hours to fly from Beijing to Paris."

"But if a wormhole is built between the two cities, then you can go from Beijing to Paris in an instant."

"And to complete this technology, you must master two technologies, which are the two holes of the wormhole."

"One is the black hole, which is the entrance."

"It needs to suck the material in, so it must use a material with a particularly large mass at the entrance."

"The second is the white hole. This hole sprays things outward."

"Since you are spraying something, you must use a substance that has no mass or even negative mass."

"Currently, these two substances have not been found on the earth, but if a breakthrough is achieved in the basic theory, finding these two substances in the universe will be just a piece of cake."

"At that time, time travel and instant movement could really be seen everywhere in our lives."

"The smooth operation of China's Sky Eye to this day is inseparable from a scientist named Nan Rendong."

"In the 90s, Nan Rendong gave up his high salary in Japan and returned to his motherland resolutely."

"Nan Rendong is determined to build China's own giant astronomical equipment here."

"But to build such a large astronomical equipment, the first problem is site selection."

"Because the conditions of this device are very harsh, it must receive signals from the universe."

"So the place to be built must be a sparsely populated and huge valley."

"Nan Rendong's team searched for valleys in the vast land of the motherland. At that time, many places did not even have roads built."

"But Nan Rendong's team built roads and bridges across mountains and rivers. After searching more than 300 valleys, they finally found Dawohan."

"It took Nan Rendong 13 years just to select the site."

"The China Sky Eye took more than 20 years from site selection, construction to commissioning."

"Because this is the world's first 500-meter-diameter, adjustable radio telescope, there is no precedent."

"During the construction process, they were all trying to cross the river by feeling the stones. It goes without saying that they encountered difficulties."

"It is a pity that Professor Nan Rendong spent 22 years presiding over the construction of the China Sky Eye, but he died of illness less than a year after the Sky Eye was put into operation."

"Some people only do one thing in their life and devote their whole life to the motherland. We call these people unparalleled in their country."

When ordinary people from all dynasties and generations heard about Nan Rendong's deeds, they all sighed.

It took 22 years to build the Sky Eye, but he died just before the Sky Eye was operational. This has to be said to be a great regret.

Although ordinary people like them don't understand the Eye of Heaven, they also know that the Eye of Heaven is extremely important to a country.

And such a person who spent most of his life on the Eye of Heaven passed away before he had time to appreciate his hard work. How could they not be moved by this?

Such people are worthy of their admiration, just as the anchor said that the country's scholars are unparalleled.

Of course, although Nan Rendong's deeds admired them, what impressed them the most was the role of the Sky Eye.

They also knew that the Sky Eye was important, but they did not expect it to be so important.

Sky Eye is related to astronomy, and astronomy is related to basic science, and progress in basic science and technology can create wormholes.

As long as you master the wormhole technology, you can travel from one place to another instantly.

Just thinking about this magical function of instantaneous travel makes their blood boil.

That is an ability that only gods can do in legends, but now ordinary mortals will be able to do it one day in the future, which makes me excited just thinking about it.

It was not until this moment that they realized the importance of the Eye of Heaven.
