Chapter 382: The distance between planets, is it controlled by an invisible hand?

Moreover, Ying Zheng's thoughts traveled through time and space, and for the first time he felt some admiration for Stalin.

Think about yourself.

What if Fusu was captured by the Huns while in the Great Wall Army.

I will definitely be very angry.

Maybe I would just give up Fusu?

But if you really think about it.

If there was a chance, I could exchange Prince Fusu back.

Then you will most likely make a choice.

And Stalin clearly had this opportunity.

But he resolutely refused.

Is this the awareness of future leaders?
After Ying Zheng thought about it.

I can only sigh with admiration and say:

"Iron Leader."

"Well, in my heart, Stalin's iron image is indeed becoming more and more solid."

And in the Ming Dynasty.

Another iron-blooded emperor, Zhu Yuanzhang.

His feelings for his crown prince Zhu Biao were even deeper.

Zhu Yuanzhang knew himself.

If you encounter this situation.

What if I let Zhu Biao lead the troops to fight and he was unfortunately captured?

Then I will definitely find a way to exchange Zhu Biao back.

Not to mention a mere marshal prisoner.

Even at a higher price.

I am also willing to pay.

On this point, Zhu Yuanzhang admitted that he was not as steely as Stalin in later generations.

……

The new sky,
Also appeared immediately.

A schematic diagram of the solar system appeared on the sky.

Because in recent times, the knowledge of cosmic astronomy has been taught many times on the sky screen.

So when ancient people saw the schematic diagram of the solar system,
Not once or twice.

Everyone was looking at the universe on the sky intently.

Prepare to learn the cultural knowledge of future generations.

【In astronomy, there is a problem that has troubled scientists for many years. 】

[And we humans may never know the answer. ]

【That is the question about the distance between the solar system and the sun. 】

【First, we need to explain an astronomical distance unit, which is called the astronomical unit. 】

[Astronomical unit is a unit of length based on the distance from the Earth to the Sun.]

[Converted into kilometers, it is about 1.5 million kilometers. ]

[It can be said to be a very long distance. ]

[Of course, later on, as humans explored outer space. ]

[We can find that the astronomical unit is still too short. ]

[It is basically useless outside the solar system. 】

[However, within the solar system, the distance scale of astronomical units can be used. ]

[So what is this strange phenomenon that has puzzled scientists for many years? ]

[As early as 1766, a German middle school teacher discovered a strange phenomenon. ]

A new picture was given on the sky screen.

A more detailed diagram of the distances of the planets from the sun.

[The distance from Mercury to the Sun is 0.4 astronomical units.]

[The distance from Venus to the Sun is 0.7 astronomical units. ]

[The distance from the Earth to the Sun is naturally one astronomical unit. ]

[Next is Mars, at a distance of about 1.6 AU.]

【At this point, you can see a pattern. 】

[The distance to Mercury is (0+4)÷10, which is equal to 0.4 AU. ]

[The distance to Venus is (3+4)÷10, 0.7 AU. ]

[The distance from the Earth is (6+4)÷10, 1 astronomical unit. ]

[The distance to Mars is (12+4)÷10, 1.6 AU. ]

【So according to this rule, the next planet after Mars. 】【Its distance from the sun should be 24+4, divided by 10. 】

【About 2.8 AU. 】

[As a result, astronomers found nothing within this range.]

[No major planets were discovered.]

[Especially based on the observation methods used more than 200 years ago, astronomers did not find any celestial bodies that could be considered planets in the area of ​​2.8 astronomical units.]

【So everyone was suspicious for a while. 】

[The previous rule may just be a coincidence. ]

[But outside the missing 2.8 AU. ]

【The next planet is Jupiter, and Saturn. 】

[They all conform to this rule. ]

[The distance to Jupiter is (48+4)÷10, 5.2 AU. ]

[The distance to Saturn is (96+4)÷10, 10 AU. ]

[This doesn't look like a simple coincidence. ]

【So astronomers summarized this magical law into a formula. 】

【That is, Titius-Bode's law. 】

【Referred to as Bode's law.】

【More than 200 years have passed.】

[People still don’t know what the meaning of this law in astronomy is.]

【Why did it come about? 】

【But according to this law. 】

[People had a reasonable guess about the approximate distances of the large planets beyond Jupiter and Saturn that had not yet been discovered at that time.]

[Astronomers discovered Uranus in 1781.]

[Before, when Bode's law was proposed, Uranus had not yet been discovered. ]

[We can only guess the location of Uranus based on the laws.]

[It should be 192+4)÷10, about 19.6 astronomical units. ]

[And now, this newly discovered planet is Uranus. ]

【Its distance from the Sun is 19.2 AU. 】

【It matches! 】

[This has caused the value of Bode's law to soar once again! ]

The sky screen also provides the image of Uranus and its distance.

And in the Shang Dynasty.

Emperor Xin was the king of Shang and also a senior high priest.

He also often observed the night sky and the stars.

This time, see the distance of Uranus on the sky.

Emperor Xin’s eyes lit up!
During the Shang Dynasty, people had already observed Mercury, Venus, Mars, Jupiter and Saturn.

But have there been other planets beyond Saturn all along?

The ancient people of the Shang Dynasty were not quite sure either.

Because Uranus is too far away.

According to the ancient observation level, it is just on the line that is slightly visible to the naked eye, but not quite visible.

Before the modern telescope was invented.

Whether it is ancient Chinese or Western astronomers.

None of them were able to see Uranus.

Emperor Xin naturally couldn't see it either.

After looking at the sky, I learned that there is Uranus in the solar system.

Emperor Xin had also been trying to observe Uranus.

But before, a schematic diagram of the solar system had appeared on the sky.

But there is no specific information on the distance of Uranus and how to observe it.

As a result, Emperor Xin could never be observed.

Now that we know the distance to Uranus.

Finally, there is some progress.

Emperor Xin happily wrote down the distance to Uranus.

Also speculating.

Beyond Uranus is Neptune.

Does Neptune also conform to this law?
