Discover galactic immigrants

How much will it cost if the planet immigrates to the whole world? In the future, we will find a planet that is completely suitable for human habitation, even with a better environment than the earth, as big as Jupiter, and its resources are 1000 times that of the earth. Human technology can also easily realize interstellar migration and the cost is very low, which can be easily borne by ordinary people. The new earth is developing better than the present earth. So more than 90% of the people on earth will run away?

If human beings want to travel outside the solar system, they can't do it with the current science, technology and theory, because even the nearest proxima centauri is 4.22 light years away, and it will take more than one million years to reach by plane.

Even at the fastest spacecraft speed, it will take tens of thousands of years to arrive, and there is no way for human beings to push the spacecraft there at present, but after all, technology is progressing and the number of human beings on the earth is increasing. When the resources on the earth are tight, human beings should first develop other planets in the solar system. When the other planets in the solar system are developed, we will move towards the vastness outside the solar system.

How can we cross the boundless interstellar space to reach another star system? You know, such interstellar travel may take tens of thousands of years. Obviously, none of the spaceships we can build at present can do it because they are too small. Even if a spaceship with a diameter of one kilometer is built, can the energy and resources it carries be used by the human beings inside for tens of thousands of years? Obviously, it is also impossible, so what can provide tens of thousands of years of resources and energy consumption for human interstellar travel? In fact, there are some excellent choices in the solar system, namely giant asteroids, dwarf planets or planets like satellites and comets.
