Chapter 730 Astronomical Observatory

If it is to commemorate Noah.

It's because of religion.

That's why the Göbekli Tepe was built.

Seems to make sense?
But is it really that simple?

“Do you remember that there was wheat here at the beginning?
That is, agriculture in our human era was born at this time.

Agriculture is not just about planting seeds in the ground.

Inseparable from agriculture is the calendar.

Otherwise you have no idea when to plant what crops.

When should farming begin?

Complete agriculture requires a complete calendar to guide it.

It can be said that it is accompanied by the development of agriculture.

A calendar is a must.

Otherwise, even if you have all the farming technology.

Without a calendar, we wouldn’t know when to sow.

You can’t grow anything.”

Now we are people working in the city.

We look at the calendar just to know what day of the week it is.

It's just about when I can take a holiday.

But for farmers, we have the lunar calendar.

But it is used to know when to sow.

But how did the calendar come about?
How did the ancients know that a year has 365 days?
A very simple truth.

For example, you are stranded on a deserted island after a shipwreck.

How do you know what point in time you are in?
What month and date is it?

How did the ancients do it?

“Our country’s agriculture was extremely developed in ancient times.

This is also due to our calendar and our study of astronomy.

It is also one of the few in the world.

We even discovered Halley's Comet as early as the Qin Dynasty.

It also accurately recorded the trajectories of Halley's Comet 27 times from the Qin Dynasty to the Qing Dynasty.

It can be said that the calendar is the foundation of our country.

Do you still remember the ten days that disappeared in history?
If the calendar is inaccurate.

For example, some previous calendars had errors.

It may not be noticeable in a short period of time, but such errors accumulate over time.

It will become a huge error.

The difference may be more than half a year.

As a result, when farming, we will misjudge the opportunity to plant seeds.

This would result in no harvest for the entire year.

So an accurate calendar is necessary."

Some people who used to farm understood the importance of the calendar.

Take for example the 24 solar terms in my country.

Whenever the time comes, you need to do something corresponding to it.

This is the function of the 24 solar terms.

Only the ancients knew how effective the 24 solar terms were in guiding agricultural production.

"Now let's take a look at some of the patterns on Göbekli Tepe.

In fact, this was the star map in the sky at that time.

How did the ancients know how many days there were in a year?

They can only do it by stargazing.”

Professor Zhou can be said to have a very clear say here.

Because of our country's observation of the stars in the sky.

It can be said to be unparalleled in the world.

Professor Zhou sighed, "It was once recorded in ancient books."

"During the Tang Dynasty, there was a man who wanted to study whether the orbit of a star was the same as recorded in ancient books."

"I spent decades on an island that was convenient for observing this one star."

"Finally, when he was old, he returned to the court to report."

"Report to His Majesty the Emperor that this star indeed moves in this way."

"You can't imagine how persistent and romantic the ancients were at that time."

"It is precisely because of this that our country's research on astronomical phenomena has continued."

"It is the most advanced and complete. Even sunspots have been recorded for a long time."

In fact, we have to mention the astronomical records of foreign countries during the same period.

It's like a blank.

They simply haven't conducted as much observation and research as we have for a long time.

But strangely, they also had a complete calendar and some star maps.

Especially after the Ming Dynasty, Western astronomy suddenly developed, which is very strange.

Si Xiaoping recalled, "Didn't Mr. Ye say that before?"

"The stars in the sky actually affect each and every one of us."

"Because according to modern science, there is universal gravitation."

"As long as there are two objects with mass, they will affect each other."

Old Wu smiled and said, "This may be what is called stargazing."

But what the three of them didn't understand was what this had to do with Göbekli Tepe?
I only heard Ye Zhen's explanation.

“The animals on the Gobekli Tepe are exactly the star maps recorded at that time.

It records the star phenomena in the sky at that time.

Because the calendar is necessary, agricultural cultivation must be combined with the calendar.

Göbekli Tepe is actually an observatory.

It can also be said to be an observatory.”

All I saw was Ye Zhen peeling off some of the patterns on the Göbekli Tepe.

It became some simple lines.

Then behind the projection, a picture of the place in Türkiye at that time was presented.

In the starry sky 12000 years ago.

Ye Zhen matched those patterns to the starry sky at that time one by one.

“You can take a look at the starry sky at Göbekli Tepe at that time.

This is exactly the pattern carved on the Göbekli Tepe.

So this stone formation is not useless.

The primitive humans at that time wanted to develop agriculture.

A calendar is needed.

And Göbekli Tepe is the observatory they need to observe celestial phenomena.

They recorded the astronomical phenomena and the time points at that time.

Why do we need to build layer by layer?
Because the celestial phenomena are different.

After a certain period of time, the calendar starts to become inaccurate.

In the second generation, the calendar could still be used barely.

But by the third generation, no one knew what the Göbekli Tepe was used for.

And then it started to decline gradually.”

Professor Yan Xin heard Ye Zhen’s explanation.

"An astronomical observatory? Used to observe the stars and guide agriculture?" Professor Yan Xin always felt that something was wrong.

Although at that time, the development of agriculture was the most important.

Without the Agricultural Revolution, it can be said that we would not have everything we have today.

No matter how much effort is put into coming up with an accurate calendar, it is never too much.

But Professor Yan Xin always felt that it was not that simple.

Song Xuan and the others in Bureau 749 don't know much about the calendar or anything like that.

But Ning Xiu knew.

Now it’s just some important festivals.

For example, getting married and having children.

You need to choose an auspicious day.

Many people will go to a fortune teller to choose a good day.

This often requires the use of the lunar calendar.

In fact, what we now call the lunar calendar is also the lunar calendar.

It is actually a lunar and solar calendar.

In the oldest calendars, there were usually only ten months.

There are thirty-six days in a month and only three hundred and sixty days in a year.

This is why our country says that 360 is a big cycle.

Later it was discovered that the solar calendar, with ten months in a year, had too large an error.

Only then did we have the version for the next 365 days.

By the time of the Xia Dynasty, the ancients already knew that there were 365 days in a year.

The calendar at that time was called the Xia calendar.

Even earlier there was the ancient six calendars.

It refers to the Huangdi calendar, Zhuanxu calendar, Xia calendar, Yin calendar, Zhou calendar and Lu calendar.

At that time, it was accurate to 365+1/4 days.

It is very close to the one year measured in modern times.

But this is still not accurate enough.

If the time becomes longer, there will still be time errors.

This led to the later synodic month, etc.

The leap year was later created to make up for the extra days.

This is the wisdom of the ancients.
