Scientists have discovered 24 "super livable" planets, and the United States has also started the development of superluminal spacecraft.

The earth is our beautiful home, where there are mountains, water, green plants and plenty of sunshine. There is air for us to breathe, and there are various ecological circles.

However, the deterioration of the overall environment of the earth is worrying. The earth in the future may not be so beautiful, and it will become lava with frequent volcanoes and purgatory full of floods. Maybe it will become a desolate ruin, or it will become a planet ruled by other creatures. ...

In the sci-fi movies that people like to watch, there are always some ferocious alien giants who come to invade the earth and even try their best to turn the earth into a planet suitable for their survival.

Art comes from life and is higher than life. Every kind of monster we see can actually find its prototype on the earth. It is also difficult for novelists to imagine and create some opposite sex out of thin air, and human brain holes are often limited.

So at this moment, the question is, is there no planet suitable for human habitation except the earth? This is not only in science fiction movies, but also in reality.

After a long period of exploration, researchers in the United States and Germany have voiced that there are 24 planets outside the solar system that may be more livable than the earth.

Researchers call the earth a "livable planet". Among the 24 planets discovered, there is also a "super livable planet", which is the most exciting.

It took unimaginable time and energy to select 24 "super livable" planets from the known 4,500 extraterrestrial planets, but the researchers did it, which also showed the unremitting efforts and perseverance of human beings.

What researchers call a "super livable" planet usually refers to a rocky planet. The heat of this planet should be moderate, that is to say, there should be a temperature suitable for living things, neither too high nor too low. In addition, having a large amount of liquid water is also a crucial factor. Without water, human beings can't live.

The earth is perfect, and humans have lived for too long. Then why do researchers say that having a "super livable" planet is more comfortable than living on the earth? What kind of experience will it be?

This is because in the Milky Way as we know it, stars can be roughly divided into three categories: G-type sun-like stars, K-type dwarfs and M-type red dwarfs. The proportions of the three are 6%, 13% and 73% respectively, which means that M-type red dwarfs have the largest number, but they are not suitable for living.

K-type dwarfs are a good choice, with a long life span, from 65.438+0.5 billion years to 45 billion years. Maybe you don't have a specific concept. If the life span of the sun is only 65.438+000 billion years, it is intuitive, but the number of K-dwarfs is scarce.

The sun has reached middle age, and then it will become brighter and hotter, and the earth in the solar system will become uninhabitable. To put it more bluntly, our earth will lose its atmosphere and oceans, and without water, life will be over.

But k dwarfs have one advantage. They are not only big enough to hold more creatures, but also have enough gravity to retain the atmosphere. In addition, such planets have no active magnetic field to produce strong X-ray and ultraviolet radiation, and no high-energy explosion, which gives life a longer time to enjoy a comfortable life.

Although researchers have discovered 24 super livable planets, it is a pity that they are all too far away from the earth, exceeding 100 light-year and beyond our reach.

The earth has existed for 4.6 billion years, so it is reasonable to find a younger and more livable home. But how to move from the earth to a new home is a big problem.

To this end, the United States has been developing superluminal spacecraft. Because judging from the current speed of human spacecraft, it is impossible to go to the newly discovered planet. Take American Voyager as an example. The speed of 16KM/S is amazing, but it is still in the solar system after flying from 1977. According to this process, it takes 18500 years to fly out of the solar system. Who can predict what the earth will be like in ten thousand years?

Therefore, making hyperdrive is the solution. To this end, physicist Harold White and his team are developing ftl engines for NASA. With this engine, it is more hopeful to reach the distant "super livable" planet.

However, combined with the current human technology, it may be almost impossible to shrink the front space, expand the engine in the rear space, and push the spacecraft forward with the "deformation" of space. But there are still dreams and hopes. At first, humans never thought that there would be cars, planes or even spaceships. With the continuous innovation of technology, I believe that the impossible will definitely become a reality.
