Why doesn t human civilization fly out of the solar system? How hard is it, exactly?

Because if you want to fly out of the solar system, there are high technical requirements, in addition to overcoming the space environment, we also need to explore the conditions of the specific place to fly so that we can build a suitable spacecraft, and the distance will take a long time.

How many years of human civilization and why it can't fly out of the solar system is not just a difficult question. No one can detect the size of the solar system, no one can understand it, and the sun is a fireball. How difficult it is, I think it must be a hundred times more difficult than climbing to the sky.

On the one hand, because the solar system is very large, and on the other hand, because of the environmental factors of the solar system, its heat is beyond our current scientific and technological means.

At least you have to make sure that the fuel back and forth is enough, and the situation outside the department is also difficult to **, if you don't understand the situation, go out casually, undoubtedly ask the astronaut to send.

The main thing is that I go out and I don't know the place where I live, what if I can't come back?

The reason why they can't fly out of the solar system is that humans are too slow.

According to the currently known edge of the solar system, it is the Kuiper belt, but many scientists believe that outside the Kuiper belt, there is an Oort nebula, and according to the range of the sun's gravity, the true range of the solar system is likely to be about 2 light years, according to the current speed of human beings, 1 light year takes 30,000 years, and the life span of human beings is only 100 years.

Therefore, there is no way for humans to really leave the Earth and the solar system, and it is likely that they have just flown over a few neighboring planets and have already died. It's not that humans don't want to fly out of the solar system, it's that humans simply can't do it, and the level of science and technology is not enough for humans to safely fly out of the earth and leave the solar system.

The composition of the solar system

The main lead-forming member of the solar system is the Sun, a G2 main-sequence star that occupies all known masses in the solar system, and the celestial bodies in the solar system move under the constraints of the sun's gravitational pull. Of the remaining mass, 99% is made up of the four large bodies of the solar system, known as the giant planets, and Jupiter and Saturn each account for more than 90% of them. The rest of the celestial bodies in the solar system (including the 4 terrestrial planets, dwarf planets, moons, asteroids, and comets) have a total mass less than that of the solar system.

The eight planets of the solar system can be divided into two groups according to their physical properties, one is terrestrial planets: small in size and high average density, slow in rotation, and few moons, including Mercury, Venus, Earth and Mars; The other type is Jupiter-like: large volume, small average density, fast rotation, more moons, Jupiter, Saturn, Uranus and Neptune, and the most special ones are Neptune and Saturn.

The reason why humans can't fly out of the solar system is as follows:

1. In the universe, the distance between stars and stars is too far. The distances between them are all calculated in light-years. For example, Proxima Centauri, the star closest to the Sun, is light-years away from Earth.

The distance of one light-year is about 9,460.7 billion kilometers. Light-years is about 40 trillion kilometers. That's enough to circle the Earth's equator 1 billion times.

For today's human beings, this is a distance that cannot be crossed.

2. The celestial bodies in the universe are separated by great distances. That's what it is, and we can't change it. All we can do is speed ourselves.

If the spacecraft reaches a speed of kilometers and seconds, it will be able to fly around the Earth without falling. If the speed reaches kilometers and seconds, the spacecraft can break free from the shackles of the earth's gravity and fly to other planets, and if the speed reaches kilometers and seconds, the spacecraft can escape the gravitational pull of the sun and fly out of the solar system. If the speed reaches 110 120 kilometers per second, the spacecraft can fly out of the Milky Way.

3. The long distance and the "slow" flight speed will inevitably cause our interstellar travel to take a long time. For lifeless probes, they can travel in space for as long as they want. But not with people.

Long interstellar travel can cause us a lot of problems.

Recent status of human vehicles breaking out of the solar system.

The farthest human probe is Voyager 1, which has been launched for 44 years since 1977 and is about 20 billion kilometers away from Earth. This is the first probe launched into deep space, and as its work time limit is gradually coming to an end, Voyager 1 will lose contact with Earth in 2025. In a future flight, Voyager 1 will fly out of the Kuiper Belt and reach the Oort Cloud in about 300 years.

What would happen if humanity discovered a civilization in the solar system that was even more backward than itself? Will they choose to invade? In the course of the solar system, people find that civilizations that are more backward than themselves will have two consequences, one is to treat them as accessories that can be controlled without restraint, and the other is to treat them as allies, helping them to develop rapidly and develop side by side with human beings.

In the course of the solar system, people find civilized behaviors that are more lacking than themselves, and sometimes, they think of occupation and invasion. Don't talk about it, let's talk about modern times. After the Qing Dynasty in China, because China's modern civilization lagged behind the Western countries, the Western countries found that the ancient Oriental countries were scarce, because the ancient Oriental countries were rich in materials, the scenery was wandering, and the high and new technology was outdated, so they risked their greed, at first according to the infiltration of chemical substances, the introduction of smoke, etc., coupled with the invasion of war, in an attempt to make China his colony, contribute to the royal family of his country, and become a colony that was forced to depend on them for survival.

When Africa was first discovered, African civilized behavior was very different from Western culture. Therefore, Africa has become an unscrupulous area for Western invaders, and all microorganisms on the land of Africa, including people, animals and plants, have become a kind of plundering resources of Western countries. Therefore, inferring from history, people in the solar system find that civilization is more scarce than themselves, will rob the network resources of the place, and solve the population that is different from their own.

In the process of the solar system, people find that civilization is more lacking than themselves, out of a kind of good-hearted, historical humanistic care spiritual essence, according to a biological justice attitude, may also attach importance to this kind of civilized behavior, and assist the outdated civilization behavior to carry out reform and innovation, so that the outdated civilization behavior to the excellent civilization behavior, hand in hand with the history of human development. If the person who helps will be grateful and benevolent, then the history of human development will go hand in hand with them, and if he has no conscience, then if people are backward in their development trend compared to them, they may have to worry about being counter-looted. In the course of the solar system, people find civilized behaviors that are more lacking than themselves, either turning outdated civilized behaviors into areas where they plunder resources, or helping outdated civilized behaviors to develop and become brothers and help each other.

If human beings find a civilization that is more backward than themselves in the solar system, they may communicate first, and they should not choose to invade, because the strength of human beings in space is also relatively average.

Possibly. Humans are a large group, and this should need to be decided by a lot of people.

It depends on whether there is a value of invasion, and if the other party has many resources that humanity needs, there is no doubt that this will definitely happen.
