Do you think humanity will one day achieve interstellar colonization? Why?

In the long run, I think it's inevitable. Once they have enough scientific and technological strength, humans will inevitably colonize other planets. Why do you say this, because the population on the earth is increasing, and the energy on the earth is constantly being consumed and reduced, in the foreseeable future, the earth energy crisis will definitely erupt.

The lack of energy directly affects the development of human beings. If human beings want to continue to develop, they must find new energy sources to replace them. And the best, the most feasible way is to immigrate to other planets.

First of all, the current level of human science and technology is not available in all aspects: the human body structure is very fragile and cannot withstand flying close to the speed of light, the cosmic environment is very harsh, spacecraft manufacturing, food, housing and transportation, etc. Spaceship materials need to withstand meteorite or asteroid collisions, such as meteorites, asteroids, meteor showers, meteorite belts, superplanets**, various cosmic intense rays, etc.

The spacecraft navigation route map, each galaxy and planet as the coordinates, the spacecraft navigation should constantly use instruments and equipment to observe the actual position coordinates of the galaxy planets and constantly correct errors, and then mark the safe spacecraft flight trajectory. Taking the galaxy planet as the coordinates, the orbit of the galaxy planet will change, otherwise there will be a deviation in the trajectory of the spaceship, and the spaceship will be absorbed by the gravity of stars, planets, and black holes, resulting in the destruction of the spaceship.

In the interstellar era, human beings migrate to all parts of the universe, and different human groups will face different cosmic environments, and humans are also living beings, and evolution is also affected by the environment. Just like the bacteria and viruses brought by Europeans to the American continent hundreds of years ago, the Europeans caused many deaths of indigenous people.

The Americas were isolated from the rest of the world for a long time, the species of bacteria and viruses on Eurasia and the American continent were slightly different, and the Americans did not evolve genes to resist some diseases. The probability of different human groups encountering other creatures in the interstellar era is relatively low, mainly due to the influence of cosmic rays and the planetary environment, as long as it is not exactly the same environment, human beings will be affected by the environment and evolve in different directions.

If human beings plan to colonize the universe in the future, the first thing is a technical problem, the space shuttle must be eliminated, and the combination of large spacecraft and space planes is the first choice. In addition, there are reasons for economic costs. Without solving these problems, migrating to space will remain just a matter of paper.

Scientists have calculated that our sun still has 5 billion years of normal burning time. In 5 billion years, the energy-depleted Sun will expand and eventually collapse into a white dwarf. And in the process of the expansion of the sun, the earth will be destroyed by the sun.

If human beings do not have the ability to escape from the earth at this time, they can only face the tragedy of extinction.

Although I am not sure at what point in the future human beings will carry out interstellar voyages, the astronomical and aerospace communities have long conceived a plan for navigating interstellar travel - pulsar navigation! In fact, pulsar navigation is not only used for interstellar navigation, but also provides autonomous navigation services for human spacecraft in the Earth's low earth orbit and deep space exploration of the solar system (other celestial bodies). This is also the basis for arousing the full interest of aerospace and national defense units in various countries, designing schemes and even conducting pre-research experiments, which is far from being promoted by the astronomical community.

As long as human beings do not want to be extinct, they want to continue forever in the universe. Space technology must be developed to achieve the ability to travel interstellarly, and colonizing other planets is the only way.

"Expansion" beyond the earth is the dream of human beings, so many telescopes open their eyes to space, just want to "go out", but that must have real skills. I believe that human beings will one day go out, and before that, they can only use their consciousness to "colonize" the universe.

The interstellar journey is a long time, not only to expand the research and development of aircraft, but also to re-examine the life span and health adaptability of human beings. There are areas on Earth where humans themselves cannot adapt, let alone distant cosmic bodies. All of this needs to be solved by the efforts of generation after generation.

There is still a long way to go for mankind, and human beings must first be more reasonable in their own resource sharing and conservation, and at the same time, cultural systems must be compatible and coexist, and at the same time, they must also eliminate those ideas of war colonization. It is better to be warlike than to be good at fighting, to be warlike will be to die, to forget to fight will be dangerous, and to be good at war will be prosperous!
