Chapter 337 Solar Spaceship
Beautiful country, Tucson.

The Zhao brothers and sisters visited the control center of Biosphere 2. This experimental facility has been in a constant stream of tourists, and the two's oriental faces did not attract much attention.

After all, this is not a particularly sensitive scientific research facility.

It's just studying the earth, the government of the beautiful country doesn't care if someone comes here to steal secrets.

Unlike the enthusiastic smiling faces of the beautiful tour guides, Zhao Wenmu noticed that most of the real researchers looked a little downcast.

Zhao Wenmu knew that the experiment was about to fail.

After all, he clearly remembered that the first experiment lasted 21 months, and now it has been 20 months, and the failure was not long after.

The second experiment a year later lasted only 10 months.

There are many reasons for failure.

The most important of these turned out to be that the concrete walls of Biosphere 2 absorbed too much carbon dioxide!
Isn't it incredible?
Bacteria in Biosphere 2 consume a lot of oxygen and produce a lot of carbon dioxide in the process of decomposing organic matter in large quantities in the soil.In a normal ecological cycle, this carbon dioxide is absorbed by plants through photosynthesis and converted into oxygen and organic matter.

These oxygen and organic matter feed the humans and animals inside.

Human and animal waste is then broken down by decomposer bacteria.

A perfect producer, consumer, decomposer matter, energy cycle, the entire ecological circle goes on and on like this, and the most perfect state is to continue like this forever.

However, the carbon dioxide released by the bacteria is chemically absorbed by the concrete walls of Biosphere 2.

This cycle was thus broken, and the oxygen content gradually decreased, eventually becoming insufficient to support human survival.

Of course, this is only one of the reasons for failure.

Regarding the failure of the entire project, the concrete wall definitely stated that he did not take the blame.

Although the reason for this failure is somewhat nonsensical, its warning significance is very important.

It fully demonstrates that the ecosphere is an extremely fragile and complex existence, and it will eventually collapse if it is neglected.

Human beings are not capable of duplicating an earth ecosystem.

At the same time, it also shows that many things need long-term experiments to find problems.

Just imagine how embarrassing it would be to find that some kind of hull material has been "stealing" the oxygen in the spaceship after hundreds of years of departure of the spaceship of the interstellar generation!

Why do many Chinese people complain about the poor driving experience of some domestically-made cars, and they feel pain all over after driving for a few hours.

In many cases, it is not that the technology is not as good as that of foreign countries, but that the accumulation of experience is not as deep as others, and there is a lack of practical experience in system integration and ergonomics.

This is true for a small car, not to mention a spaceship that can accommodate tens of thousands of people.

Every system and every sub-module of the spacecraft must be verified through long-term experiments.

Biosphere 2 can be regarded as one of the sub-modules.

In fact, the failure of Biosphere 2 is inevitable. This system can almost be regarded as an earth ecosystem built on an alien planet.

It's just that the species inside come from the earth.

Want to build an alien colony for $2 million?Could it be that you are thinking about farting!

If you think about it with your ass, you will know, let alone 200 million US dollars, even [-] billion US dollars is impossible!

But it still makes sense.

Although it is impossible to completely copy it to the spacecraft.

After all, no matter how big the spacecraft is, it is impossible to move the ocean, desert, and rainforest. If that is the case, it is better to install a planetary engine on the earth and drive the earth to run like in the wandering earth.

Really leave home.

In fact, the entire solar system is an exquisitely designed interstellar spacecraft.

For its perfection, man cannot even imagine.

The earth is the crew compartment of the spacecraft.

The vast deck with a diameter of 12000 kilometers and a surface area of ​​5 million square kilometers provides enough living space for hundreds of millions of passengers.Its just the right gravity allows passengers to swim easily in the water, run happily on land, and fly freely in the air.

The atmosphere with a total weight of 5000 trillion tons is the porthole and innermost shield of the spacecraft.

It is transparent and heat-retaining, allowing the sun to bring heat well, and then storing them, so that the deck is always maintained at a very suitable temperature.If there is no atmosphere, the surface of the earth can heat up to 120 degrees Celsius during the day and drop to minus 180 degrees at night. I am afraid that no living things can survive except tardigrades.

In addition, it is also well isolated from various cosmic rays and small meteorites, otherwise tens of billions of micro meteorites weighing less than 0.1 grams each year are enough to exterminate human beings.

After all, they travel hundreds of times faster than bullets.

Not to mention cosmic rays flying at the speed of light or sublight.

Of course, radiation protection is not only due to the atmosphere, but mainly due to the geomagnetic field.

It is like the energy shield of the spacecraft, resisting the solar wind from tens of thousands of kilometers away.

This porthole is spacious and bright, and the brightness is adjusted regularly (alternating day and night), allowing people to live calmly, work at sunrise and rest at sunset, and everything is in order.

The sun is the nuclear power engine of the spacecraft.

It has a diameter of 140 million kilometers, a mass of 200 trillion trillion tons (one billion less is not possible!), and a power of 385 billion billion watts!The energy generated in one second is enough for human beings to use for hundreds of millions of years!
Using nuclear fusion as energy, it is enough to continue to burn stably for 100 billion years.

Is there any more unparalleled controllable fusion than this? !
The distance between the sun and the earth is so perfect.

The distance between the sun and the earth is 1.5 million kilometers, which is called an astronomical unit in astronomy. This distance just falls on the habitable zone of the sun.If the distance between the two is reduced by 5%, the earth will become as hot as Mercury, and the temperature of the hemisphere illuminated by the sun will reach several hundred degrees Celsius during the day.

If this distance expands, the earth's environment will be too cold, which is also not suitable for life.

Although the violent solar wind is harmful to life, it also establishes a safe zone with a radius of up to two light years for the solar system.

Within this range is the realm of the sun.

It keeps most other cosmic rays out.

At the same time, relying on its huge mass and huge gravitational force, the sun captures most of the dangerous celestial bodies rushing from outside the solar system, so that the life on earth will not be destroyed by the impact of celestial bodies.

Jupiter is the frigate of the spacecraft.

Jupiter, Saturn, Uranus, and Neptune, as the "big men" on the periphery of the spacecraft, rely on their huge physiques to establish a safety barrier around the periphery of the earth.

Comets and other stars that break into the solar system will be attracted by the huge gravity of these big guys, captured by them and eventually torn apart.

Comet Shoemaker-Levy 1994 struck Jupiter in July 7 with an energy equivalent to 9 trillion tons of TNT.

Just imagine if it hits the earth, what will be the consequences?
On average, each person on earth can share more than 5000 tons of TNT.

5000 tons!
As a little bit of common knowledge, this thing does not explode when ignited, and the combustion is very stable and gentle.

It is these big guys who have emptied the wandering celestial bodies in the solar system, so that the earth can obtain sufficient security.

This exquisite and huge spacecraft in the solar system is running at a speed of 220 kilometers per second.

Nature is awesome!
