Chapter 828

The elder knocked on the ground with his metal walking stick, and a floating three-dimensional holographic interface jumped out on the floor in front of his seat, projecting a whole Sirius Star System in mid air: "for your understanding, I can use your earth civilization's relevant cognition of Sirius to explain.

As you can see, Sirius is a binary system. Different from your original solar system, we have two stars. They rotate around each other. The period is about 50 years of your earth. The average distance between them is 20 times of the distance between the sun and the earth.

Sirius a, that is, the star you can see with the naked eye on the earth, is also called the master star. It is a star 23 times brighter than the sun. In terms of volume, if the earth is an orange, it is a big watermelon. However, due to its loose mass, its actual mass is only more than twice that of the sun, and its surface temperature is also twice that of the sun, up to 10000 photos Degrees.

Sirius B, also known as the companion star by you, has a mass basically equal to that of your sun. However, so much material is compressed to be about the size of the earth. Therefore, it is a white dwarf with a surface temperature of 25200 degrees Celsius, which is higher than that of the sun. However, since there is no new energy generation inside, the remaining heat will be radiated The form radiates out of outer space, and Sirius B will eventually cool down, about 200 million years later.

Our mother star was born in the interstellar dust cluster of such a binary system. Your earth scientists did not calculate the existence of Sirius and the third star, that is, star C, through ultra-precision radio telescopes until modern times.

Star C is a watery planet with a mass close to the earth. Our parent star is called "Nibiru".

Nibiru was born in such a binary system. Because the mass and distance of Sirius A and B were in a relatively balanced state, Nibiru was captured by the gravity of star B not long after its formation and became a planet rotating around it.

The distance between Nibiru and B is basically equal to 0.6 Earth Day distance, that is, we are lucky to live in a livable range, which has evolved primitive life.

You may feel strange that star B, which is twice as hot as the surface temperature of the sun, will not be dried up so close to it?

In fact, this is not the case. Although the surface temperature of star B is higher than that of the sun, because it has died, there is no intense stellar activity in the sun, and there is no super coronal eruption. In our eyes, it is just a star emitting ordinary mild heat.

It can be said that the civilization evolution course of Nibiru planet is almost a sister chapter of the evolution of earth civilization. Similarly, 600 million years ago, Sirius B caused the surface temperature of Nibiru planet to suddenly decrease significantly due to the cooling effect, resulting in the emergence of the ocean. Then, it is the process of evolution step by step from the primitive creatures.

Seventy million years ago, the Nibiru planet began to have a higher primitive group, that is, the Nibiru dragon, the ancestor of amphibians and reptiles. At the same time, there also appeared the primitive ancestor of our blood moon man, the primitive horned lizard.

At this point, you may think that the biological evolution of Nibiru has many similarities with the earth.

However, in essence, they are very different. The biggest difference is that under the same stellar mass, the mass of Sirius B is close to the sun. Nibiru planet finally forms a tidal locking effect because it is too close to its own star. "

When Li Weigong heard this, he couldn't help but interrupt: "elder, is this situation similar to Venus in the solar system?"

The elder nodded: "yes, in fact, the easiest thing to understand is your Earth's satellite moon. You can imagine the earth as star B of Sirius galaxy and the moon as our mother star Nibiru. When she rotates around her own star, she always has only one side to her own star."

Li Weigong looked up and thought for a moment. He suddenly understood something, so he asked, "do you want to say that only half of your mother star can actually shine the sun?"

The elder nodded slightly, and the holographic Galaxy simulation enlarged the model relationship between Sirius Galaxy B and Nibiru: "God gave us a good environment for biological evolution on our planet, but he cruelly took away half of them, making half of them indulge in the night forever. Only in the years when the star of wolf Galaxy a turned behind us that day, can we feel a little warmth and light from 20 times the distance..."

Li Weigong was surprised: "but you just said that half of them are as suitable for biological survival as the earth. Why do you think the blood moon people seem to live in the dark world?"

The elder nodded helplessly: "you forget what I just said, in the evolution of primitive creatures, there were two branches of higher civilization, one is Nibiru dragon and the other is primitive horned lizard..."

"Your planet has evolved two branches of advanced creatures?"

"Yes, the descendants of Nibiru dragon, because of their large size and fierce nature, occupy the top of the food chain, enjoy a large living space and bathe in the sun. Our ancestors of blood moon people lived in dark and humid underground caves and lived on plant roots and underground water. They not only faced the killing of Nibiru dragon, but also dealt with many ferocious animals like them Predators

This is where the fate of the blood moon man is different from that of the earth man. Your God of the universe is so partial to you. He used a huge natural disaster to exterminate the dinosaurs that were also dominant. He also used a severe cold to solve most of the carnivores that could not adapt to the environment, so as to help the weak human beings to the top of the food chain.

However, we blood moon people are not so lucky. Our planet does not have the natural disaster of comet impact. Nibiru dragons have survived for a long time and become the masters of Nibiru planets. They gradually evolved into smaller bodies, grew feathers, possessed advanced wisdom and became the race dominating the sky. "

"Dominating the sky?" Li Weigong suddenly thought of the huge ships of the White Fleet, which were the shape of birds on earth.

"Yes, you don't think that only land creatures can evolve higher intelligence?

In the course of 60 million years, the descendants of Nibiru dragon have gradually evolved into contemporary feather people. They have wings behind them, can fly in the sky, and have extremely intelligent brains. Through the early exploration of their own flight ability, they have long begun to enter the stage of mechanical simulation flight. This speed is far beyond the reach of you people on earth. "

"That's true. It's only a matter of thousands of years since we people on earth have the dream of flying, and it's only 200 years since the invention of the plane..."

"Therefore, the feather civilization has realized the importance of speed for biological evolution from a very early time. Only by obtaining a faster speed can we obtain more living space. If the civilization starting point of blood moon people and earth people is walking, their civilization starting point is flying!"

Li Weigong was stunned. A race that started flying. What should their civilization look like?
