What are the possibilities for human beings to settle on the moon?

It is almost impossible to settle on the moon, because the acceleration of gravity on its surface is only 1/6 of that of the earth, and the gravity on its surface is difficult to capture air, so the temperature difference between day and night is huge, which can exceed 350 degrees Celsius, but human beings can establish an independent space on the moon.

Method 1: Built on its surface (more expensive, shorter time), there will be an independent gravity device at the part where the space is connected with the surface.

Method 2: Inside the moon (the cost is relatively small and the time is relatively long), the space will be connected with a tunnel on the surface, which is an underground city dug out. Because the closer to the inside, the greater the acceleration of gravity, so there is no need to spend energy to build a magnificent gravity system.

But people's current scientific and technological level is limited, which is not enough for them to immigrate to the moon. Based on this, American scientists put forward the "doomsday ark" plan, that is to say, if modern people are silent in nuclear war, asteroid impact and geomagnetic transformation before emigrating to the moon, they can send the earth's civilization, human genetic code and plant seeds to the moon for the survivors to use and restore human civilization.

In other words, with modern science and technology, modern civilization can be sent to the moon for preservation, but it will not be immigrated.
