Hand rubbing nuclear fusion live in the wilderness

Chapter 488 Dyson Ball?
Seeing the things in the photo, Han Yuan was taken aback for a moment, and then he took a deep breath. At the same time, the live broadcast room exploded again.

[Fuck!what is this? 】

[Hexagonal man-made structures? 】

[Dyson ball? 】

[This cliff is man-made, it is impossible to be so regular in nature, and there are holes in the middle! 】

[Is it a Dyson ball? 】

[I don't feel like a Dyson sphere. The Dyson sphere is actually a dead proposition. What is the surface area of ​​the Dyson sphere?With so many resources to build this thing, isn't it good for controlled nuclear fusion? 】

[Controlled nuclear fusion also requires materials such as deuterium, tritium and helium. There are not many of these things on the earth, and even the deuterium, tritium and helium in the entire solar system will not last for 1000 years. 】

[I feel that the Dyson sphere was a bit too idealistic at the beginning, and the solar system should not be able to find so many substances to make Dyson spheres. If we really want to do it, we must be able to go to other galaxies to find substances, but without Dyson spheres, there is not so much energy to power it. Other galaxies, so it feels a bit pitted. 】

[Then what is this in front of you?Large astral structures?Can't you see such an obvious artificial structure? 】

[Dyson balls are something that high-level civilizations disdain, but low-level civilizations can't do it, and they need too many resources. 】

[Anchor anchor, tell me, is it necessary to make a Dyson ball?Is the thing in this picture really a Dyson sphere? 】

[Everyone is denying the Dyson sphere. Do you know who proposed the theory of the Dyson sphere?O Freeman Dyson!He is a famous physical scientist who has won various world-class awards such as the Hughes Award of the Royal Society of London, the Planck Award of the Physical Society, and the Oppenheimer Memorial Award. His speculations are much more reliable than those of you who don’t understand anything. okay? 】

There was a lot of discussion in the live broadcast room, and the sudden appearance of the hexagonal artificial creation stunned everyone, and the number of viewers also soared all the way, directly breaking through [-] million.

In the studio, Han Yuan didn't have time to pay attention to these bullet screens at all, he was carefully observing the picture in front of him.

This is a photograph of a red dwarf star, 10.7 billion light-years away from the earth, a single star system similar to the solar system, called the Gliese 1061 galaxy.

The difference is that the star of this solar system is a red dwarf, while the star of the solar system is a yellow dwarf.

The reason why this red dwarf was photographed is because it meets the conditions for the birth of life.

In the vicinity of the red dwarf star Gliese 1061, there are three planets, two of which are in the habitable zone.

Of course, this so-called habitable zone is much closer to the sun than the earth.

Because Gliese 1061 is a red dwarf star, according to its spectral data, the surface temperature is only about [-] to [-] degrees, which is far lower than the [-] degrees on the surface of the sun.

With such a low surface temperature, according to human calculations for alien life, its habitable zone is naturally closer to the star.If the Gliese 1061 galaxy is converted into the solar system, then the habitable zone should be located between Mercury and Venus.

In this region, planets can receive enough stellar radiation to promote the flow of matter and evolve into life.

But relatively speaking, in fact, in reality, countries in the search for extrasolar life have never set their sights on red dwarfs.

Because the habitable zone of the red dwarf is very close to the host star, there is a high probability that the planets there will be "locked" by the star's gravity, causing one side of the planet to always face the star, and the other side always faces away from the star, just like the moon One side always faces away from the earth.

This scenario would make the climate in both hemispheres of the planet extremely harsh.

Secondly, because the stars and the planets are very close, and the flares of the red dwarfs will expose the planets to X-ray and ultraviolet radiation, which is very unfavorable to the development and evolution of life.

More importantly, the planet is too close to the star, and the planet's atmosphere is likely to be eroded by stellar activities such as flares.

In addition, although the lifespan of red dwarfs is very long, they also go through a very violent process when they are formed. At that time, the activities of the stars are very violent, and the planets around them are scorched and disturbed. It is believed that it is difficult to preserve the water on it. Without water, the hope of life is slim.

Although in the Milky Way, the number of red dwarfs accounts for more than 50.00% of the number of stars, there is a higher possibility of life, but when humans are looking for extrasolar life, they rarely pay attention to red dwarfs.

Of course, this is for the current cognition of various countries.

For South Korea, it is indeed possible for life to be born near a red dwarf.

In the vicinity of a red dwarf star, even if the planet's movement is locked by the star's gravity, the surrounding planets are not unable to make themselves habitable.

If there is a small amount of carbon dioxide in the atmosphere of a planet, the heat in the atmosphere will be retained to a certain extent, and they can be dispersed to surround the entire planet, forming some temperature differences and adaptive storms, enough to exchange substances.

In addition, if the mass of a planet is large enough, it is possible to form permanent thick clouds on the side facing the star. This kind of cloud can reflect the light from many stars, thus making the climate cooler.

In addition, there are some planets that have other ways to make themselves "livable".

Some planets, for example, are between one and ten Earths in size and mass, and have thick atmospheres, 50 percent of which are hydrogen and helium.

And the ultraviolet radiation from the star and some motion of the planet itself towards the star may evaporate the original atmosphere of this planet, leaving only the rocky surface under the atmosphere, and this kind of planet may evolve into a rocky surface and a A world with abundant liquid water.

Of course, these things are not enough to prove that red dwarfs can give birth to life. The real evidence comes from the system in his mind.

Before that, Han Yuan obtained knowledge information on intermediate materials, including a biological material, which was taken from the skin of a creature born on a certain planet in a red dwarf galaxy.

That material has various properties such as high temperature resistance, corrosion resistance, extremely strong toughness, hardness, etc. From this, it can be seen that life can indeed be born near red dwarfs.

Therefore, after the launch of the No. [-] outer space telescope, when searching for extraterrestrial life, Won selected three targets.

Among them, there must be the nearest galaxy to the earth. The other two targets are the Gliese 1061 galaxy, which is [-] light-years away from the solar system. It is a red dwarf galaxy. It has three planets, two of which are in the habitable zone. superior.

The other star system is extremely similar to the solar system. It is the Theta-XJ24 star system 32 light-years away from the earth. Its owner is also a yellow dwarf star Theta-XJ32. It has thirteen planets, including four in the habitable zone.

Originally, South Korea had placed high hopes on the Theta-XJ32 star system. After all, from the observation data, it is more suitable for the birth of life.

But unexpectedly, the Theta-XJ32 star system did not find the corresponding information data, but found amazing things in the Gliese 1061 red dwarf galaxy.
