Chapter 331 Chapter Thirty-Thirty

Night fell slowly, but the scene was stunned. Even Liu Xinyu didn't care about the queen's majesty, she opened her mouth wide in surprise, stared at the 'globe' in front of her.

Today, everyone finally has the concept of 'planet'!

It has been more than three hours since the end of the sea trial, Zhao Dahe spit and talked about his great discovery.

Using the projection length of the wooden stick at noon measured at Taotuzhizhou and the Red Lotus Sect, combined with the projection length of the stick at noon in the Qixia Kingdom, plus some knowledge passed down by Zhao Dahe himself, Zhao Dahe used Zhang Using a brand-new mathematical knowledge calculation, after repeated proofreading, Zhao Dahe calculated the diameter of the earth for the second time:

The diameter calculated by Zhao Dahe last time was 126,000 kilometers;

This time, Zhao Dahe calculated a diameter of 128,700 kilometers.

The last time Zhao Dahe calculated according to the records and data of the sect, as well as the celestial chart, plus the mathematics of the Zhang family, etc. - there are many approximations. This time, new calculations were made using Zhang's mathematics, stick projection, etc., some approximations and errors were corrected, and a more accurate number was obtained.

The diameter of the earth is 128,700 kilometers, and we live on a star! And the area displayed by the earth image is only about one-tenth of the surface area of ​​this star!

There are still nine-tenths of the world, which is an unknown world!

Zhao Dahe's calculations are very complicated, and there are many calculations involved, even with the help of Huang Mingshan and others. Huang Mingshan and others have grown into the scientific personnel and pillars of the Zhang family.

Seeing the dense calculations and proofs on the three-foot long Tianma paper scroll, everyone felt a little dreamy.

And this time Zhang Shengye didn't refute, because compared to Zhang Hao's 'casual talk' back then, Zhao Dahe proved his conclusion with mathematical methods and various evidences!

Precise figures make all words pale.

The earth under our feet is a star, and we ourselves are the people who live on the stars! For the planet under their feet, after discussion, Zhao Dahe and Zhang Hao named it Tianyuan.

The so-called Tianyuan refers to the beginning of heaven and earth, and the center of Zhoutian. In ancient legends, there are 366 stars in Zhoutian (it is said that Zhang Hao looked at the sky full of stars and did not know how to count the 366 stars), but what everyone has observed so far is 365 stars. A star has disappeared.

For a long time, everyone has had many guesses about the disappearing star, one of which is that there is another "original" star that has not been found. Everyone named this star 'Tianyuan'.

But for so many years, many astrologers and even many masters of cultivation who study "Zhou Tian Gong" have been looking for this 'Tian Yuan Star'. In the end...it was right under my feet!

Such a result made countless people on the scene tie up their minds, which is really too dramatic.

Then Zhao Dahe carefully adjusted the direction of the "globe" that he had just made, or "Tianyuanyi", so that the "earth image" on the Tianyuanyi tilted up. Upturning in the east and sinking in the west.

But for the time being, Zhao Dahe doesn't have the concept of latitude and longitude, the Arctic Circle, the equator, etc. He just makes adjustments based on the information he already knows.

But this adjustment is very similar to what Zhang Hao did before.

Zhao Dahe adjusted for a while, and finally took a few steps back to look at it, and then said to everyone: "Everyone, this should be the approximate location of the map on the Kuodixiang."

Liu Xinyu finally breathed out slowly, and said, "I have a question, why are we in the north and not in the south? Since we live on a 'planet', why can't we be in the south?"

Zhang Hao smiled: "It's very simple, because we discovered this secret, so we stipulated that we are here in the northern hemisphere!"

It can still be like this... Liu Xinyu blinked in a daze for a while, and finally nodded in agreement. Yes, it turned out to be us who discovered it, of course we are in the northern hemisphere. Traditionally, it is believed that the direction of north and south, the north is the most precious; the direction of east and west, the east is the most respected.

But Liu Xinyu still has doubts, "Since we live on one planet, why don't we go to the outside world? What is between each star? How far is it? Can we reach other stars?"

Zhang Hao stared at the Queen dumbfounded: Are you thinking of going on an expedition to other planets now? Your ambition is a bit big! Well, ambition is a good thing, better than no goals. Having said that, practitioners have a long lifespan, maybe Liu Xinyu will really conquer the starry sky one day.

However, Zhang Hao couldn't answer Liu Xinyu's question right now—gravitation or something, it would be a bit shocking to say it now, and it would reveal himself.

The discovery of universal gravitation represents the beginning of human transformation and manipulation of the natural world. Why water flows downhill, why people stand on the ground instead of floating into the sky, the movement of the sun, moon and stars, and many other mysteries all require the key of 'universal gravity'.

But it takes a genius to explain gravity and prove it mathematically. It's a pity that Young Master Zhang remembers a lot of things, but he can't remember many more things. He knows about gravity, but how to prove it... sorry, no idea!

In fact, using mathematical methods to prove universal gravitation is a very complicated calculation that requires more complicated experimental data and so on. The most important thing is to need enough scientific accumulation.

Zhang Hao will promote the development of science and industry, but he will not casually pluck the seedlings and encourage them to grow.

Before universal gravitation, an important scientific basis is needed: Kepler's theorem, which is to use mathematical methods to calculate planetary orbits, etc.

Yes, the universal gravitation needs to be calculated from a large perspective, and it needs to look for traces from astronomy and a large number of observations. It is difficult to obtain enough data only relying on observations inside the planet.

So facing Liu Xinyu's question, Zhang Hao could only shake his head.

Not to mention Zhang Hao shaking his head, even the current Zhao Dahe can only shake his head.

As the two shook their heads, the atmosphere fell silent again. After a while, Liu Xinyu smiled lightly: "Forget it, if you don't understand it, you can't understand it, life goes on anyway.

Zhang Hao, what happened today is an eye-opener for me, but to be honest, I still have some doubts. "

"Your Majesty, don't say you are confused, I am also confused. But I believe in the data in front of me more. Our eyes and senses can sometimes deceive us, but the data that has been accurately measured and calculated will not deceive us."

Liu Xinyu nodded slowly, "Just in time, we are still discussing the issue of the year name during the Chinese New Year, so let's use 'Tian Yuan' as the new year name in the future. I think we have the qualifications!

This year is the first year of Tianyuan, and our calendar will continue the name of Tianyuan forever! "

You also want to be this queen forever. Zhang Hao was a little joking in his heart. He had just begun to have a hazy understanding of the world, and the queen's ambition had grown to such an extent.

Everyone gradually dispersed, but Zhang Hao did not ask for secrecy. Because it is not necessary, and the future development of Qixia Kingdom will also need this kind of geographical knowledge to pave the way.

Even if other countries know about it, it’s useless—the world cannot be explored without steel warships! This is the world of practice, and the sea is full of monsters. Not to mention ordinary wooden boats, even warships made of black iron with insufficient quality may not be able to cross the open sea.

Because there was no need to keep it secret, the news spread throughout Qixia Kingdom after only a few days. In particular, the empress officially used 'Tianyuan' to mark the year, which aroused huge repercussions.

The legendary Tianyuan star has been found, and it is actually under our feet—this news alone is enough to shake the practice world!

Looking for the stars that have not been found for tens of thousands of years, it turned out to be a real donkey looking for a donkey.

But then it caused even more shocks-we actually live on a star? Or, we actually live on a planet?

The earth turned out to be spherical? real or fake? So why didn't we fall? What is beyond the planet? Are the stars in the sky all planets? The earth under our feet really has a diameter of 128,700 kilometers?

The news spread throughout the west of the Fertile Continent at an indescribable speed, and then spread rapidly. The rest of the countries cannot block the communication between the Nascent Soul stage, let alone the communication between the Transformation God stage.

However, the 'round earth theory' spread, but the related mathematical calculations and so on are kept secret - the results can be made public, but the process must be kept secret!

And the best evidence to prove the theory of a round earth is the lighthouse!

The light of the lighthouse is bright and shines directly into the sky, especially in this world with a thick atmosphere, and there are many layers of white clouds in the sky. After these white clouds are illuminated by the light of the lighthouse, they virtually become a sign to verify the theory of the circle of the earth.

In relatively clear weather, observed from tens of miles away, the clouds are almost attached to the surface; and as they approach, the clouds get higher and higher.

There is also Yuyang Mountain, the highest peak in the Qixia Kingdom, which used to be the residence of the Nine Suns Sect. When viewed from a distance, the top of the mountain is the first to be seen. And the sun in the morning and evening will also stop at the top of the mountain.

There were many explanations for the sunshine in Yuyang Mountain in the past, but today's explanation is the most convincing. It's just that the reaction was too great.

But it also led to more discussions - why didn't we fall? What is the force that binds us? Could it be... is this the legendary power of the stars?

And here comes a more serious question: Since we are on the stars, where is the legendary fairy world? Where is that hell?

As the discussion intensified, the Zhang family took the opportunity to push Zhao Dahe to the foreground, and used this to attract a lot of attention.

This time, Zhang Hao did not use the name of Dayang Group, but the name of "Zhang Family". Knowledge must be in your own hands!

In such an atmosphere, the Zhang family finally made an important decision: to build a school. A school that imparts various scientific knowledge such as cultivation, alchemy, industry, commerce, geography, etc., recruits students from Qixia Country.

And the Zhang family promises: free education!

Name of the institution: Beidou Academy.

For a while, Qixia Country became even more lively.

(People often say that they send me blades. They are so enthusiastic that I can't sleep most of the night because of the emotion.)
