If one day in the future, humans will make Mars their "second home", what year will it be?

Faced with the earth that is now riddled with holes, one day in the future we may really have to look for another home. For now, the one with the best conditions is Mars.

When will this day come? Although many scientists now propose that Mars can become our second home, in fact this matter is still far away from us.

1. It takes a long time to transform the external ecological environment

According to science, Mars was indeed suitable for biological development a long time ago, but due to the collision with an asteroid, it became no longer possible. Suitable for biological survival. Therefore, if we want to make it our second home, the first thing to do is to restore it to its original ecosystem. Based on the time it takes for the earth to develop a new ecosystem, it can be seen that it will take at least 1,000 years. Time, and in these 1,000 years, people's science and technology may be further improved, thereby speeding up the operation of the Mars ecosystem, but it will still take a long, long time to reach this level. But the evidence for water on Mars is already overwhelming, so moving in this direction is essential.

2. Science and technology have very big limitations

As far as current science and technology are concerned, although people have landed on the moon and are very confident that they can also land on Mars, this is a very The migration of a large number of people is not just a few people but a group of people, so how should we do it? Scientists have also put forward quite a few ideas, but the current level of science and technology still does not support us in doing so. Even transporting a person to Mars is very difficult. The technological development in this process will take at least hundreds of years to reach this level. Although human science and technology have developed rapidly in the past two centuries, it is still not enough for us to get out of the earth.

3. This project is still in its infancy

Try to think back. In fact, this idea only appeared in the past few years. Before that, people had no idea at all. Have imagined this problem. Although many solutions and methods have appeared in people's field of vision in recent years, and most of them have certain scientific theories, the actual direction of implementation has not yet been determined. In the future, we have no absolute certainty that we can quickly achieve this goal. degree. Therefore, there is still a lot of uncertainty and randomness before then, and Mars may not be the only environment we can use as a second home in the future. After all, the area we can explore now is also limited.

Although many ideas have been proposed, it will still take a long time before we move to Mars. If we are lucky, we may be able to reach Mars in a few hundred years. If various difficulties cannot be overcome quickly, we may not be able to reach Mars in even thousands of years.
