Published the magazine "Atlantics"The idea of a planet both dark and dark could be the future homeland of humanity if we wanted to live in other solar systems.
In his report,Arab", Several years ago, the focus was mainly on constrained planets.
I realized that these planets are some of the best choices for looking for earth-like places where our grandchildren can settle.
The dark worlds, on the one hand, and the infinite sun, on the other, may be the future of the human race.
Astronomers believe that most planets in our galaxy, where temperatures are similar to those of the Earth, are likely to be constrained.
As the orbital period is the same as the rotation period, these planets are known to display their own side of the sun, just as we see the same side of the moon that circulates around the earth.
The reason for this abundance of constrained planets is very simple: up to three quarters of the suns in our galaxy are red dwarfs, dwarf dwarfs, the smallest and coldest stars of the Sun.
Any planet that revolves around one of these pygmies should be close to its star in order to ensure the lives of humans. It should be noted that astronomers have recently discovered seven Earth-sized planets in the Tractist-1 habitable zone, all of which are susceptible to debt.
The author says that talking about these planets for the moment is a speculation. But we try to learn enough about the dynamics of the restricted worlds to understand how they work and the kind of civilization we can build there, and where humans can settle on a strangled planet.

It seems that the answer to this question is what is called the glass line, the twilight line that separates the dark side from the dark side of the planet.
"This place is perhaps what is called the" zone of life ", where the climate is not very hot or cold, but it is blocked," said Daniel Angerhausen, astrophysicist at the Center. of accommodation and space of the University of Bern. Between eternal twilight and eternal dawn ".
He suggests that men in the Gilles area could generate geothermal energy by using cold water on the dark side and hot water on the bright side.
"To access liquid water on a strangled planet, you need a system to cool the bright side and warm up the dark side," Lyudmila Karon of the Institute said. Astronomy Max Planck.
"The ability to live on these planets depends to a large extent on the ability of humans to transmit heat," said the author.
Karon's computer models show that the constrained planet can have two powerful jets, functioning as the jet-stream on Earth.
But if the planet is too close to the sun, there can be only one jet stream, directly above the nearest part of the sun. In this scenario, the heat can be confined to the bright side of the planet.
According to Karon, regardless of the problems encountered to find liquid water, a constellation of dwarves around a red dwarf may face other problems, especially as the Red dwarf stars are known for their "erratic temperament" and tend to explode in space.
These explosions can heat up the atmosphere of the planet in the habitable zone, while the star can also extrude materials that degrade the atmosphere.
"Even with the atmosphere, the bright part of the planet can be exposed to lethal radiation," said Vivian Parmentier of the University of X-Marseille.
The light of a red dwarf can not provide enough UV wavelengths to produce ozone, so that the planet can not, unlike the Earth, contain the layer of dwarf. ;ozone.

The writer said that anyone living on this planet also needed to eat and breathe. For their part, physicists Joseph Gill and Amery Wandel of the Hebrew University are studying the possibility that plants survive when exposed to radiation. At first, plants can grow in the ocean to take advantage of a protective water layer.
But in the end, if the star becomes less violent, the planet can develop an air chamber thick enough to allow plants to grow on the ground.
"People can live on the bright side, but they need to dig and build pipelines to bring ice to the dark side," said Adib Paradise, a student in astronomy and astrophysics at the University of Toronto.
Heaven also believes that people can also learn to live in the dark and cold part. "I'm from Minnesota," he added.
People there can live in all kinds of areas that astronomers can call "unfit for habitation".
In conclusion, Paradise emphasizes that the greatest challenge for humans living on a constrained planet can be a very different space from the Earth.
If they decide to live on the safe side, they risk "losing their relationship to the universe" because they will never be able to see the stars. Their vision of time will change because "there will be no change in the space."
