Is it possible for human beings to establish a permanent living base in space?

It is easy to build a base in space, but it is difficult for human beings to live.

Gravity is a very important factor. Without gravity, the air on which human beings depend will not circulate, so we can't wear spacesuits every day, can we? That's alive?

Water and space are short of water, even if there are chemicals produced through chemical reactions, it is not inexhaustible. We still need to get the necessary energy from the earth, and it cannot last forever.

If people have lived in space for a long time and their bodies have adapted to life in space, it will be difficult to return to the earth. There is no gravity in space, and people lack necessary exercise. As a result, for example, after living in space for 65,438+000 years, they returned to the earth and just got out of the space capsule, and their legs were broken, because their bodies had adapted to the wandering life in space.

Only wait. Maybe there will be that technology one day, but it's definitely not our turn.

However, I heard that living in space can last for decades.
