Is it feasible to colonize outer space in various sci-fi movies or comics? Can the production and life of the colony be guaranteed?

At the current level of science and technology:

1. the influence of cosmic rays on people and creatures and on future generations.

2. The influence of weightlessness on people.

3. How to overcome weightlessness?

4. How advanced is the manned spacecraft that can carry so many people for colonization? These include structural problems, fuel problems and propulsion methods. The above is just similar to Gundam building a colonial satellite in space. If you want to colonize other planets, 1 is suitable for planetary problems, and 2 is environmental reconstruction at the planetary or regional level.

5. If there are local protozoa, there is a problem of biological pollution prevention. At present, it is very difficult to launch a rocket load. To build a big guy suitable for space colonization, it is still necessary to build so many materials.

Theoretically, the fate of any species is reproduction and exploration. We have made an early exploration of celestial bodies, but we still need in-depth research and observation. Immigrating to outer space is a logical choice.

Energy is also a major factor. It is more important to capture solar energy in other places in space. With the increase of human energy demand, we will use all relevant technologies to establish colonies in outer space to obtain valuable solar energy resources, which is another good idea. Without the constraint of gravity, traveling is difficult and expensive. Having other colonies with less gravity in space will make it easier to travel between planets.

The idea of space migration first appeared in the field of science fiction, and often appeared in novels, TV programs and "futuristic" movies. But now, we are starting to take this topic seriously.

The main obstacles to spatial migration are cost, travel time, life support system, resource availability, radiation exposure, communication and psychological factors. Some of these problems always need to be worried to some extent, but others will become controllable. For example, the cost of launching a pound of material into space is about $250-which makes the launch cost astronomical. However, with the reuse of launch performance and the improvement of fuel efficiency (some substitutes are as low as $65,438+00 per pound), a large number of launch tasks required by immigrants can be effectively completed.
