Universe dominance

Here in the asteroid belt of the solar system, the "Ocean" spacecraft is constantly advancing in the void, but compared with the vast universe, it seems to be standing still, even though its speed has exceeded 30 kilometers per hour at this time. The speed of a second still seems very, very slow in the vast universe.

The originally boring interstellar journey was now within the scope of the asteroid belt, allowing scientists to study the asteroids around them, so it became very busy.

"Based on the data we have obtained so far and conducting reverse deduction, more than 3 billion years ago, there was definitely a planet in the asteroid belt with a mass that reached the planetary level. At least this mass would not be much lower than Mars."

"However, as time goes by, as the mass of Jupiter continues to increase, its mass slowly becomes second only to Mars in the solar system. Its powerful gravity, coupled with the huge gravity of Mars, at a certain moment, When the three planets aligned, they were pulled under a huge gravitational force."

"Boom! The planet fell apart and became the asteroid belt it is now. Countless fragments continued to spread in the void, relying on inertia to form an orbit-like asteroid belt."

Astronomers Tang Boyuan and Dong Zhifei, who came aboard the "Ocean" spacecraft, were using supercomputers to simulate the development history of the solar system.

The oldest thing in the solar system is naturally the sun, which has a long history of more than 5 billion years. As a yellow dwarf star, the lifespan of the sun will be as long as 10 billion years, so the sun has just reached middle age at this time.

The lifespan of the earth is about 4.6 billion years, and its history is also very long. Of course, the earth has been a dead planet throughout its long history. It was only about 635 million years ago that the earliest organisms with complex structures began to appear on the earth. As for microorganisms The existence history of the group will be longer.

The history of human beings appearing on the earth is even shorter. Early humans slowly appeared about 50 million years ago. According to the research of scientists, many kinds of people appeared at the same time at a certain period in the history of human evolution. This kind of difference between races is not the difference between yellow people, black people, and white people.

Nowadays, these three types of people are usually said to be able to reproduce with each other. In fact, they can only be regarded as one kind of human race. In the development process of the earth's history, several human races have appeared, and they cannot reproduce with each other at all. , is like the difference between a tiger and a lion.

Of course, in the end, our ancestors, Homo sapiens, gained the right to rule, and all other human races gradually disappeared. As for how they disappeared, I think everyone should know that natural selection and survival of the fittest.

Therefore, scientists are very enthusiastic about studying the history of the earth and the solar system, because only by knowing history, that is, knowing yesterday, can we cherish the present and survive better in the future.

"Didi~" Dong Zhifei, who was responsible for monitoring the surrounding planets and celestial bodies, knew when he heard this sound that the detector must have discovered another large celestial body, and he quickly looked over.

"This is Ceres!" Dong Zhifei compared the discovered large planet with all known planets and immediately knew that this asteroid was Ceres.

Ceres is the smallest dwarf planet in the solar system and the only dwarf planet located in the asteroid belt. Discovered by Italian astronomer Piazzi and announced on January 1, 1801. In 2006, the International Astronomical Union redefined Ceres as a dwarf planet. Ceres was once considered the largest known asteroid in the solar system.

To put it simply, the identity of Ceres has always been controversial internationally. Just like Pluto, it was initially positioned as having the same status as the eight planets. Later, with the understanding of the universe, it was downgraded to a dwarf planet.

Ceres was initially considered the largest asteroid, but later with in-depth research on it, astronomers upgraded it and classified it into the dwarf planet sequence, which is the same level as Pluto.

"Discover Ceres, discover Ceres!"

The dull spaceship was detonated by this news!

Ceres is one of the main targets of this scientific expedition. As the largest asteroid that has been discovered in the asteroid belt, Ceres is even positioned as a dwarf planet by the latest astronomical international community because it is basically round and has a stable orbit around the sun. orbit, but it has not cleared other asteroids in its orbit.

The most important thing is that Ceres is not only the largest body in the asteroid belt, but more importantly, based on previous observations, it is inferred that there should be a large amount of water resources on Ceres.

Another important purpose is to find out what the mysterious white bright spot on Ceres is!

"Ceres's current speed is 16 kilometers per second, and its orbit radius is 412 million kilometers. It is in a state of falling back, and its speed is increasing slightly!"

"Currently 4239 kilometers away from Ceres!"

…

"Finally Ceres was discovered. I thought it was hidden in that nook and cranny!" After receiving the news, Li Fu hurried over. Ceres is one of the important targets of this scientific expedition, but the asteroid belt has been visited for more than ten years. Days passed, but no trace of it was found. It was really a master at playing hide and seek.

"Don't talk about Ceres. It was first deduced by scientists using formulas, and then scientists discovered it by focusing on observations in the asteroid belt!" Speaking of the stories of these planets in the solar system, Tang Boyuan, who studies astronomy, naturally knows it very well. .

"Oh, is there such a story? Tell it!" Li Fu became interested as soon as he heard it.

"Yeah, it's boring anyway, let's listen to it to relieve our boredom!" Others were also very interested. There really isn't much to do in space, especially when flying, listening to stories is also a good idea. way to relieve boredom.

In 1766, when a German middle school teacher named Johann Titius was studying a set of numbers, he found that each item in the set was related to the six major planets known at the time (i.e. Mercury, Venus, Earth, Mars, There is a certain relationship between the distance ratio between Jupiter and Saturn) and the sun (the distance between the earth and the sun is set as 1 astronomical unit).

Titius's friend, the astronomer Bode, was well aware of the importance of this discovery, so he announced Titius's discovery in 1772. This string of numbers has since attracted great attention from scientists; it is known as Titius. Deuce-Bode's law is the average distance between the planets in the solar system and the sun.

At that time, people had not yet discovered Uranus and Neptune, and thought that Saturn was the farthest planet from the sun.

In 1781, the British-German Herschel discovered Uranus at a position close to 19.6 AU (the eighth item in the sequence). Since then, people have firmly believed in this rule.

According to this rule, the fifth term in the sequence, the position 2.8, which is the asteroid belt where we are now, should also correspond to a planet, but it has not been discovered yet. As a result, many astronomers and astronomy enthusiasts embarked on a journey to find this new planet with great enthusiasm.

On New Year's Eve in 1801, Italian priest Giuseppe Piazzi was still observing the stars attentively. Suddenly, he discovered a very small star through the telescope, exactly at the position of 2.8 in Tidius-Bode's rule. The planet changes position over several days of observation.

However, when Piazzi wanted to further observe the asteroid, he fell ill. When he recovered and tried to find the asteroid again, it was missing. Piazzi did not give up this opportunity. , he thinks this may be the planet that people have never discovered.

Astronomers have mixed views on Piazzi's discovery. Some people think Piazzi is right; others think it may be a comet. There are many theories about this planet, and the astronomical community is talking a lot.

Months have passed, and the debate has not been resolved. However, this controversy attracted the attention of German mathematician Gauss. Gauss thought, since astronomers cannot find Ceres through observation, can they find it through mathematical methods? Many astronomers disagree with Gauss's suggestion.

Even astronomers can't find Ceres. Could Gauss still be able to calculate it? Friends also advised him not to waste his time and talents on this hopeless problem.

The young Gauss had his own opinion. He believed that astronomy was inseparable from mathematics. It is impossible to become an excellent astronomer without strong knowledge of mathematics. This is also the case in the history of astronomy. Kepler relied on his mathematical talent to discover the three laws of planetary motion; Newton also relied on his profound mathematical knowledge to discover the law of universal gravitation.

On the night of December 31, 1801, the German astronomer Obers pointed his telescope at the sky at the time predicted by Gauss. As expected, Ceres miraculously appeared again!

Gaussian's calculation method succeeded. The planet that Gauss found from the tip of his pen became the best New Year's gift to mankind after being hidden for a whole year. This gift shows people the great role of mathematics in scientific research.

As Tang Boyuan slowly told the story of how Ceres was discovered, the young scientists lowered their heads in thought!

"Compared with the perseverance and perseverance of senior scientists, I think we are still too impetuous!" Li Fu thought for a long time and expressed everyone's thoughts.

This group of scientists from the Fuyun Group have now achieved extremely brilliant achievements, but all of this is based on various auxiliary tools provided by Li Fu. Practicing Yuanli improves everyone's brain development, so that everyone can better understanding of the problems encountered in scientific inquiry.

Providing advanced scientific research instruments and advanced theories and methods can save everyone from countless detours, but all this has also caused this group of young scientists of Fuyun Group to be impetuous and lack the persistence and persistence of their predecessors.

It is conceivable that if the people of Fuyun Group were placed in the historical conditions of their predecessors, they would definitely not be able to study one thing for decades or even a lifetime like the previous scientists.

Although taking shortcuts has contributed to the current glory of Fuyun Group, it has also slowly caused everyone to lose the quality of persistence and perseverance that scientists should have. This will not be of any benefit to the future development of science and technology. Sometimes it is just a walk. Detours, some hardships, some hardships and setbacks are actually a good thing!

Hearing Li Fu's emotion, the scientists of the Fuyun Group far away on earth also fell into deep contemplation. When they encounter problems and difficulties, they habitually rely on Li Fu instead of settling down and working wholeheartedly. Go study it!

"It seems that we have to make everyone suffer more in the future!"

Li Fu murmured in his heart when he found out.

You must know that in the early scientific research, there were no computers, so many data statistics and analysis had to be calculated by hand. The scientific ancestors just used pens and paper to calculate again and again, and slowly and slowly Various scientific truths have been explored. Thinking about the high-level mathematics we have learned, just looking at them makes people dizzy, not to mention taking the trouble to continue to study and calculate.

And there are many, many things that you have to explore by yourself. Not only the scientific truth, but also there are too many, too many important discoveries in the history of mathematics development. These discoveries were all slowly explored by the predecessors of mathematics. .

Mathematics is the most important subject in science today and the foundation of modern science. Almost all sciences are inseparable from the application of mathematical knowledge!

Of course, now with the assistance of computers, when scientists calculate complex data, they no longer need to hold a pen in hand and face the paper to perform complex calculations over and over again like their predecessors. The super computing power of supercomputers allows scientists to Calculation results can be calculated in a very short time.

However, it is also easy for scientists to gradually lose the persistence of their predecessors in the exploration of scientific truth. In scientific exploration, many things actually need to be explored over and over again and tirelessly before they can discover scientific facts on the surface of complex matters. truth.

Li Fu looked at the dark starry sky outside the window and kept thinking in his mind. With the seeds of super civilization, Li Fu was destined to lead China and mankind to quickly leave the earth and move towards the interstellar universe. But whether it is really useful to encourage the seedlings, and whether it will allow We are slowly losing the spirit of scientific exploration that has been passed down for a long time.

But if we don't lead the development of science and technology, judging from the speed of technological development on earth, it may take a long time to get out of the earth, and we don't know how long it will take to get out of the solar system.

The vast universe is too vast and there are so many powerful civilizations. It is still a great blessing that the people on earth can develop peacefully and steadily for so many years. Of course, it may also be because the earth's location is too remote. But no matter what, it is best to control your own destiny in your own hands.

There are so many things worth thinking about, especially for Li Fu to think about and ponder deeply.
