The Creator of the Second Dimension

Dr. Tan was stunned when he heard this.

The three-body problem is a basic problem in astrophysics. The specific model is the mutual motion of three particles in space under the influence of their respective gravitational forces. It is one of several major mathematical problems.

Currently, there is no precise solution to the three-body problem known to human beings, only a special solution under specific initial conditions, and once the initial conditions change, even just a little bit, it will completely change the whole system and get completely different answers.

When they observe massive celestial bodies, they will also be exposed to some similar problems, but this is not the focus of the research.

Now that Xu Rui mentioned it, I feel a little surprised.

"Mr. Xu, is your new work related to mathematics?"

Dr. Tan asked subconsciously.

It can't really be about three stars.

"Related to alien civilization."

Xu Rui answered briefly.

"You really like this setting."

Dr. Tan also watched "Country Teacher". After all, many theoretical models of special effects in it were made by his own students. As a teacher, it is also necessary to check the teaching results.

The aliens that appear in the movie are just a joke to a researcher like Dr. Tan.

In fact, human beings themselves are a miracle of coincidences piled up.

For example, why humans and related races have five fingers instead of four or six fingers, ordinary people may analyze the benefits of five fingers at first glance, the help to evolution and so on.

But the real situation is just that the ancestor of Five Fingers survived by accident.

Four fingers or six fingers, it doesn't matter at all in the era when 90% of the creatures are extinct at every turn.

Even some species that originally dominated the world were completely extinct and became fossils because of the weather changes in just a few hundred years.

Dr. Tan is not engaged in paleontological research, but he has also heard about it. He thinks that if aliens really exist, then their image must be completely different from that of the earth, whether it is physical form, social structure, or even the intention of civilization. .

The aliens in "Country Teacher" are still too anthropomorphic for the sake of plot development and audience understanding.

Of course, this is harmless.

"I'm thinking about a story that shows the sociology of the universe, Dr. Tan, can you give me a reference?"

"Cosmosociology?"

Dr. Tan came interested.

It is impossible to say that astronomy people do not have a heart to discover aliens.

Xu Rui quickly explained the two axioms of cosmic sociology, the chain of suspicion and the concept of technological explosion to Dr. Tan. During this period, some students gathered to watch, but Dr. Tan drove them back to continue the report.

Dr. Tan just nodded and remained silent all the time, without interrupting, until Xu Rui finished speaking, he let out a long sigh of relief.

"Mr. Xu, sometimes I really suspect that it's a waste of your talents to make movies and animations."

Dr. Tan praised first.

"Your cosmic sociology does have some research value. Of course, we don't have a reference now, but this theory can already explain some problems, such as the Fermi paradox. Mr. Xu, you should know."

"Well, it means that aliens evolved a million years earlier than humans."

Xu Rui replied.

The Fermi paradox was proposed by the physicist Fermi. He pointed out that if human beings have developed extremely high technology after a million years of development, and can explore the Milky Way and find extraterrestrial civilizations, then other galaxies, or the Milky Way Why can't there be a civilization that evolved a million years earlier than humans to visit humans on other planets?

It boils down to either there are no aliens, or aliens should have been to Earth long ago.

The description of this paradox is simple but straightforward, and scientists have been trying to solve this paradox for many years.

Some believe that the earth is a special planet, and there is no alien civilization, and some believe that alien civilization once existed, but they cannot contact the earth, and the development level of civilization is very average. Some believe that aliens have come to the earth, but we do not know.

There is no way to prove these conjectures, so this paradox has become something that science fiction enthusiasts and scholars talk about.

But cosmic sociology and dark forest theory can solve the Fermi paradox to a certain extent: that is, all advanced civilizations are hidden, and the low-level civilizations found by themselves are cleaned up. In the universe, cruel survival occurs all the time war.

The two discussed it, and Dr. Tan said again.

"Of course, this is just a sci-fi theory. If you think carefully, humans should still be able to find some traces of weak civilizations, some unnatural traces of destroying other civilizations."

"Well, it's just a sci-fi idea."

Xu Rui naturally knew it too.

"I'm going to set up the alien civilization on Alpha Centauri. The civilization on it is going to leave the galaxy due to the chaos of the Trisolaran system. Doctor, what do you think?"

Alpha Centauri is the closest star system to Earth, only 4.37 light-years away.

"Nanmen Er. No wonder you want to discuss the three-body problem."

Dr. Tan suddenly realized, but quickly frowned, went to the computer, and knocked several times.

"However, you may be disappointed."

On the computer are the astronomical photos of Alpha Centauri, as well as some data, which can be found in the astronomical star database.

"Although this is a three-star system, because the mass of the third star is too small and the distance is relatively long, it can actually be regarded as a system composed of a binary star system and another star. At present, this star system is stable."

Dr. Tan explained, but soon he also understood that this level of detail is not important. Compared with the sun and the earth, Alpha Centauri is indeed a lot of chaos. If the life on the planets in that star field Instead of being destroyed because of this, it has grown up, which is indeed a great threat to human beings.

After that, Xu Rui and Dr. Tan discussed some details and technical issues. After all, Xu Rui is not a specialized researcher, and it is also important to refer to the opinions of scientists.

Dr. Tan is not the kind of pedantic intellectual. He knows that sometimes drama is more needed than complete scientific rigor, so he also helps Xu Rui make suggestions.

Xu Rui returned to the company after having dinner at the observatory, sent Xu Rui away, and Dr. Tan returned to the laboratory.

"Teacher, are we going to help make a movie again?"

Some students curiously asked that the special effects in "Country Teacher" have their own power, which makes these students feel more confident when they go home and pretend to be fake with their family and friends. in the adjustment.

"Go, go, is the report finished, is the analysis done, is the observation plan for next year finished?"

Dr. Tan chased away the students.

But I have a little more expectation.
