今天,宇宙航行的大門将要被人类打开了。別的星球上到底有沒有生命?这已經是越来越受到注意的問题。許多学者都推測别的星球上也可能有生命,并且举出了若干証据。当然,这些証据还都是間接的,不能作为肯定結論的根据。这个問题的最后解决,当然有待于更多的事实根据,特別是比較直接的材料。不过对这个問題作各种各样的探討,却是非常有兴趣的。我們在这里不能全面地探討这个极为复杂的問題,我們只限于研究这么一个問題:可能存在着生命的星球是不是一定要具备象地球一样的条件?就是一定要具备我們星球的这种温度,因而有大量液态的水,并且大气中有氧气?
Today, the gate to cosmic voyage will be opened by humans. Is there any life on other planets? This is an issue that has drawn more and more attention. Many scholars speculate that there may be life on other planets, and cite a few pieces of evidence. Of course, these evidences are all indirect and can not be used as a basis for confirming the conclusion. The final solution to this issue, of course, needs to be more factual basis, especially the more direct material. However, it is very interesting to make various discussions on this issue. We are not here to discuss this extremely complex issue comprehensively. We are confined to the study of the question of whether the existence of the planet of life necessarily possesses the same conditions as the earth, that is, it must have such a temperature on our planet and therefore There is a lot of liquid water, and there is oxygen in the atmosphere?
