If there is a new habitable planet, will humans immigrate?

If the earth is really uninhabitable in the future and a habitable planet is found, human beings may try to send some people to a habitable planet, so as to immigrate, preserve and reproduce human racial civilization, but at present, it is unlikely.

At present, scientists have not found planets suitable for human habitation around the solar system. Some scientists have found some planets that may be suitable for human habitation far away from our earth, but so far, human beings have not left the solar system, and the alien immigrants mentioned now only exist in theory.

Migrating to other planets is far less easy than in movies, but it is actually very difficult. The speed of human spacecraft is very fast for us humans, but it is really too slow in the universe. Voyager probe 1 launched in 1960s and 1970s just flew out of the solar system. Outside the solar system, there is the Milky Way. Outside the Milky Way, there is an endless and huge universe, which shows how small the speed of human spacecraft is in the universe.

If a planet suitable for human habitation is really found in the future, the only way to immigrate is to immigrate a small number of people, so that human civilization can prosper, because the size of the spacecraft, funds and other factors limit this result.

Furthermore, if human beings really want to reach the level of immigration in the future, the chances of success are very small, because the universe is very dangerous, all kinds of meteorites, space junk, weightlessness and cosmic ray radiation, and human beings are likely to get various diseases in the spaceship, and even the whole spaceship may be seriously destroyed.

As mentioned earlier, planets that may be suitable for human habitation have been found far away from the earth. It takes several years to get there at the speed of light, and it may take at least hundreds of years at the speed of a human spaceship, which means that several generations may spend their lives in a spaceship. In addition, how to have enough fuel and how to replenish fuel for hundreds of years is a big problem.

To sum up, if the earth is really uninhabitable, human beings will definitely emigrate to other planets, but it will certainly be difficult. Therefore, we call on everyone to take good care of our mother earth from now on, and never hope that the time of immigration will come!
