I have a little black hole

Liu Helong then explained the reason for the failure of the Biosphere 2 experiment plan: "The Biosphere 2 experiment was originally carried out in a state of crossing the river by touching the stones. Although the scientists at that time already had research on the Earth’s biosphere A lot of research results have been made, but these results cannot support such a complicated experiment.

The Biosphere 2 project is designed to conduct ecological and environmental research in a closed state, to help humans understand how the earth works, and to study whether humans are suitable for survival under the conditions of simulating the ecological environment of the earth.

In order to be as close as possible to the natural environment, the soil, turf, seawater, and freshwater in the circle are all taken from different geographical areas of the outside world, and then reused through certain manual treatment.For example, the seawater used in the experiment was prepared by mixing the incoming seawater and freshwater in an appropriate ratio.

Why did this experiment fail?Scientists have summarized this: In addition to the causes of more carbon dioxide, less oxygen, and water cycle imbalance, imbalance in the relationship between biological species is also an important reason.

It turned out that although the designer simulated a variety of ecosystems in the "Biosphere II", the imported organisms were mainly producers, and the types and numbers of animals, fungi and bacteria were small. The pollinating insects died and some plants Only flowering will not bear fruit.

Due to the reduction in the types and amount of animals, there are few reasons for the wrong proportion of plants. In the real biosphere, the atmosphere, water, and plants corresponding to each person are so vast. What about the second?The ratio of environmental resources to people is seriously too small. At that point of the atmosphere, water, plants, etc., even living alone is not enough, let alone a few people.

More carbon dioxide and less oxygen are the result rather than the cause. More carbon dioxide and less oxygen are because the plants are relatively too small to convert so much carbon dioxide produced by people and plants themselves and release oxygen. The consumption rate of oxygen is higher than the production rate, The production of carbon dioxide is higher than the consumption.

We all know that the planet we live in as a huge biosphere system is very, very complicated, and it is almost impossible to completely simulate it with a laboratory!

As the largest ecosystem on earth, the structure and work of the biosphere can maintain a relatively stable state for a long time. This phenomenon is called the steady state of the biosphere.

First of all, from an energy point of view, the continuous flow of solar energy is the driving force for the normal operation of the biosphere.The conversion of solar energy into chemical energy that can be used by organisms is achieved through the photosynthesis of green plants.This is the energy foundation on which the biosphere depends.

Second, from the material point of view, the atmosphere, hydrosphere and lithosphere provide various necessary substances for the survival of living things.The three-pole structure formed by producers, consumers and decomposers in the biosphere connects a complete circuit from inorganic matter to organic matter, through multi-level utilization of various organisms, and then decomposed into inorganic matter for recycling.The biosphere can be said to be a materially self-sufficient ecosystem, which is the material basis on which the biosphere exists.

Third, the biosphere has multiple levels of self-regulation.For example, when the amount of carbon dioxide in the atmosphere increases, plants will increase photosynthesis and increase their absorption of carbon dioxide.

After a creature is extinct, other creatures in the biosphere that have the same role will take its place; when the number of plant-feeding animals increases, the number of related plant populations and natural enemy populations will also change, thus making this animal population The quantity is controlled.

Although the biosphere has the ability to self-maintain a steady state, this ability is limited.The impact of human activities on the biosphere in many ways has exceeded this limit, posing a serious threat to the steady state of the biosphere.

It is precisely because of the fear of this threat that our company’s interstellar immigration plan is so important, and how to allow humans to survive in the colony for a long time is the most important thing to consider to truly complete the colonization.

Therefore, our experiment is so important, and because the environment outside the planet we want to colonize is of course different in the future, our laboratory construction plan adopts a fully enclosed construction design.

If you look carefully at the outer layer of the laboratory we designed, you can see the advantages of our design. All the systems in the entire laboratory are closed together.

In addition, in order to better simulate various complex alien environments, all of our laboratory constructions adopt a double-layer construction design. In addition to shielding the influence of the external environment, the outermost layer will also install a large number of environmental simulation equipment to simulate Such as extreme cold and hot environment, cosmic ray impact, meteorite impact, etc. the impact on the ecosystem.

The interior of the laboratory integrates all the equipment for the entire ecological cycle. We have designed the equipment required for the system such as the water circulation system, oxygen circulation system, animal and plant circulation system, and lighting system.

Of course, these devices also need the support of various branches and laboratories, which is another reason why we took this plan to the company’s regular meeting for discussion, rather than directly handing it to the boss for approval. There is no strong support from everyone. Such a huge construction plan cannot be completed!

This closed-loop design almost does not need to consider the interference of external factors on the interior of the laboratory, so it is okay to build anywhere, and it is not necessary to go far to find a desert to build a laboratory.

However, because the scale of our laboratory construction is indeed large enough, in order to save construction costs, we can also find an area with cheap land to buy land. Anyway, with the convenient transportation, there is no problem where to conduct experiments.

What's more, our company's artificial intelligence systems and intelligent robots can help us better manage and maintain the laboratory, so don't worry about it!"

After listening to his explanation, both Lei Tiantang and others understood why their laboratory did not need to be built in the desert to avoid the influence of the external environment.

Indeed, even if the laboratory is built in a desert with a relatively simple ecosystem, it is difficult to meet their experimental needs. After all, their experimental plan is not as simple as the simulation experiment of the Biosphere 2 experiment.

The purpose of their experiment is completely different. The experiment of Biosphere 2 wanted to simulate the Earth’s biosphere and wanted to see the performance of the artificial biosphere in a small area. The content of the experiment is closer to the earth’s environment. Even the most important sunlight is natural light. How can such a simple experiment meet the needs of the colony's ecosystem construction after interstellar migration!
