What should humans do when the life of the sun ends?

The end of the life of the sun, the solution of mankind;

The first way is for humans to leave the earth. Now humans can fly out of the earth. In thousands or tens of thousands of years, the speed of human flight will be much faster than it is now. By then, we may not only fly out of the solar system, but also fly out of the Milky Way, where we can find a planet similar to Earth.

In this way, we can realize interstellar migration. Now scientists have found planets similar to the earth in the universe, but they are too far away from us. At the current speed of human flight, there is no way to fly there. After the continuous development and progress of human science and technology in the future, it should not be difficult to fly there.

The second way is that we leave the solar system with the earth, or we can directly create a sun to continue to shine and heat for the earth. Now scientists have known that the burning of the sun is mainly due to the reaction of internal nuclear fusion. Scientists have been studying controlled nuclear fusion. If one day humans developed controlled nuclear fusion, it would not be difficult for us to build a sun.

At that time, we can find an empty area in space outside the solar system, and then create a sun to continue to provide light and heat for the earth. Although it seems impossible now, anything is possible after the development of science and technology to a certain extent. After all, ancient people never thought that one day we could fly out of the earth and see the whole picture of the earth.

The third way is that we can absorb the energy of other stars and then inject it into the sun, thus prolonging the life of the sun. The main reason for the exhaustion of solar life is the exhaustion of internal energy. If it can be replenished, it can continue to burn, just like our stove.

As long as you keep pouring combustible materials into it, you can keep burning. This will not only protect the earth, but also let our sun continue to serve us. The above are some conjectures put forward by scientists, but the specific way to adopt depends on the degree of human scientific and technological development.
