Maybe many people will wonder, why feces? Yes, on the way to the moon, our astronauts took a poop on the moon at the same time, and then left this poop in space, so that human beings can better study the later things.
The bag is still there, no one knows what happened to it, but some people will wonder why we should study the Baba belt where astronauts were still in space more than 50 years ago. Human excrement is uncomfortable, but 50% of it is composed of bacteria, which means life. All this is a perfect ecosystem. After all, there are more than 1000 kinds of microorganisms in our intestines. In the past 3.9 billion years, we humans and the earth have cultivated these bacteria step by step, and we have gradually been born from them. But at this time, the moon is still a barren land, lifeless.
Apollo 1 1 landed on the moon. At the same time, human feces, urine, food residue, vomit, saliva and so on all contain various microorganisms, and today, 50 years later, all these things have become hot natural experiments of NASA.
So what is the vitality of these creatures? If this experiment can be further studied, it will be quite sensational.
These rubbish are fungi on the earth, and the items with the highest content of bacteria and viruses are best preserved. After all, we all know that fungi are very tenacious, which means that this is another microorganism that may survive.
In fact, the harsh environment has repeatedly stressed that the earth is so suitable for human habitation in all aspects, while the moon is just the opposite. First, it has no magnetic field to deflect cosmic radiation. Cosmic radiation makes it difficult for all life to survive. Secondly, because there is no ozone layer, it can't absorb the ultraviolet rays of the sun. The vacuum environment on the earth is totally unsuitable for life, because there is no oxygen, nitrogen, carbon dioxide and so on. Third, there is no atmosphere on the moon, so its temperature difference between day and night-for example, it is-180 degrees Celsius at night, and it will soar to 100 degrees Celsius during the day, which means there is a temperature difference of nearly 300 degrees. Can these bacteria and fungi survive?
Now, NASA scientists have mentioned that the bacteria in these closed excreta need to return to the earth again, and scientists have made great contributions. But first, make sure these shit bags are completely closed. Once the closure is not perfect, they will directly become dry. And they may be broken due to repeated severe temperature differences.
There is a spore bacterium in the Arctic, which has been revived after thousands of years of freezing. If the Baba bacteria on the moon is in a similar situation, in fact, this research value is remarkable. If it can be evaluated as the limit of life, it will be of great significance to the future trip to Mars.
Astronomers from NASA say all this will be true, so scientists have raised this question. Is life on earth brought by the excrement of some astronauts or aliens from outer space? Could the Baba bag left by astronauts be the beginning of a new terrestrial planet?
In fact, we generally believe that the survival of the fittest, natural selection. There is no popular theory of the origin of life involving the excrement of astronauts, but it has to be discussed from a scientific point of view. This idea is completely reasonable.
After all, microorganisms can survive on the moon, even if they are dormant. For various reasons, it may mean that those microorganisms can live in the depths of space for a long time, even across the universe. If they meet an earth-like planet, they can reproduce and spread life along the way, and culture will happen.
