Great fusion of heaven and earth

Chapter 1466 Oxygen is poisonous
In fact, the main world also has its own speculation about the void in the universe.

If the earth is the center, then the surrounding universe with a scale of one billion light years, that is, the local supercluster of galaxies, is composed of many cavities and filaments.

People in the main world made some explanations for this, that is, after the universe, there are no galaxies at all.There is only very homogeneous matter and very small fluctuations in density.

So in some places the matter is slightly denser and in other places it is less dense.Areas with greater density have greater gravitational pull, causing them to gather more.On the contrary, in the area of ​​low density, the smaller the gravitational force, the less aggregated.

As time goes by, the clumps become more and more numerous.They grow on specific scales, determined not just by gravity, but by other material properties of the gas.In cosmology, there is a whole body of theory devoted to this, starting with Newton's theory of small waves.

And according to the study of the cosmic redshift phenomenon, it clearly shows how the high-matter-density region shrinks under the collective gravitational force, and plunders a large amount of matter from the low-density region, and then the low-density region, that is, the cosmic void, begins to expand.

At the same time, the main world also carried out an experiment with an unknown time span in a universe.

That is, in a certain high-matter-density region, artificial means are used to create a low-matter-density region, with a range of about three to five light-years.

That is, artificially created a cosmic void, and wanted to see if the cosmic void theory I proposed was correct.

Although this experiment has just started not long ago, the high-matter-density area has already begun to absorb the matter in the low-matter-density area through gravity. According to the calculation of the main world, there will be a large and five-dimensional area in about tens of thousands of years. A light-year cosmic void.

In this way, the main world has almost settled the theory of the void in the universe, but the main world has no way to explain why there are some galaxies inside the void.

But these have nothing to do with the super god world. In this world, everyone doesn't know much about the technologies of cosmology and space-level civilization.

In their world view, civilization is divided into two types, one is pre-nuclear civilization, and the other is post-nuclear god-level civilization. As for space-level civilization, it is a transitional period in their view, or an inspiring god-level civilization. The period of civilization is not a big deal. It is too common in the universe. It is so common that no one thinks that these civilizations are a big deal.

But in fact, aerospace-grade civilizations are the main civilizations of other worlds, and the so-called post-nuclear civilizations are called civilization remnants or civilization survivors in most universes.

In all universes, population is always the most important. As long as the number of people in a civilization is large enough and new populations are born continuously, then the development of this civilization is normal.

Without population, there is nothing. This is the maxim of the development of civilization in the universe, and population is everything.

According to the views of all known aerospace-level civilizations, the development path of the god-level civilization of the super god universe is wrong. The pursuit of personal strength is meaningless. Only the strength of the whole people is truly powerful.

So from the very beginning, the main world would not have waited to see the super god world, if it wasn't for the long life of the ladder computer and the first generation of gods, radiation immunity, and the ability to resist the great peace after the second generation of the body, and the physical body crossing the universe These abilities really make the main world a little greedy.

And now the eyes of the main world have shifted from the best long-lived life and radiation immunity to the physical body crossing the void of the universe, because on many habitable planets, the main world has not found traces of oxygen, just It seems that oxygen is unique to the earth.

However, the main world didn't have any ideas about these things before. The big deal is to transform it. If a large amount of algae is released on a habitable planet with water, it will naturally transform into a planet suitable for human habitation.

It's just that during the transformation during this period, the main world discovered some things, which made the main world feel that something was wrong.

When transforming a certain planet, because of the use of a large number of algae organisms and a large number of genetically modified fast green plants, a planet became the Carboniferous Earth in a short period of time, and the oxygen concentration was as high as 35. %, then the Carboniferous coal burning event occurred, but in outer space it is not so much a coal burning event as a rainforest spontaneous combustion event.

This incident opened the minds of all the people present, and they named this incident the Man-made Carboniferous Event, and then reported it to the Central Research Office of the main world.

Then there was an idea in the central research room, why the earth is special, other planets do not have so much oxygen content, oxygen is not a necessity in other worlds, but is used as a corrosive agent ,Why is that?
Then everyone started to discuss about oxygen, and the main discussion focused on oxygen free radicals.

Everyone knows in medicine that the harmfulness of oxygen free radicals, when the human body suffers from trauma, poisoning, or heavy trauma such as excessive bleeding during major operations, the human body will be in a state of hypoxia, and energy metabolism will be impaired. Pigment oxidase is unable to reduce oxygen into water, and the oxygen atom will be deprived of an electron, from harmless oxygen to lethal active oxygen free radicals.The peroxidative killing of oxygen free radicals mainly destroys the structure and function of the cell membrane, damages the mitochondria, cuts off the energy source of the cell, destroys the lysosome, and makes the cell autolyze.At the same time, it also has a harmful effect on the non-cellular structure of the human body, which can damage the adhesive on the blood vessel wall, make the completely sealed blood vessel riddled with holes, cause blood leakage and exudate, and then lead to edema and purpura, etc. .

Similarly, when the coronary arteries that supply blood to the heart suddenly convulse, the cardiomyocytes will undergo a series of metabolic changes due to hypoxia, and the antioxidant content in the cardiomyocytes will decrease, making the chemical reactions that generate oxygen free radicals due to hypoxia. And relatively faster, at the moment when the coronary artery spasm is eliminated, the myocardial cells are suddenly reperfused with blood, and a large amount of oxygen is converted into oxygen free radicals, and at the same time due to the relative deficiency of antioxidants, oxygen free radicals cannot be removed , As a result, the highly lethal oxygen free radicals seriously damage the myocardial cell membrane, and a large number of ions overflow from the cardiomyocytes, and the latter can disrupt the current signal that controls the beating of the heart, causing ventricular fibrillation, resulting in death.

The same aging is also the cause of oxygen free radicals. Oxygen free radicals can attack fatty acids on cell membranes to produce peroxides. This substance is a highly toxic substance that will damage nucleic acids, proteins, etc. in the body and cause a A series of cell destruction effects, the more oxygen free radicals accumulate in the human body, the faster the aging process. The age spots on the faces of the elderly are often caused by the oxidation and decomposition of lipids by oxygen free radicals to form malondialdehyde.

There are also incurable diseases such as arteriosclerosis, hypertension, osteoarthritis, cataract, diabetes and Parkinson's disease, which are all related to oxygen free radicals.

And after using the medical platform for so many years, the main world also knows that the reason why the medical platform makes human beings young is to regularly remove oxygen free radicals, so that the oxidation level of the human body is cleared to zero.

For these things, the main world also found a lot of existences who abandoned their bodies, such as the immortals in the third world of God, as well as Huainan King Liu An from Marvel, and Zhang Ziyang, these big bosses, haha ​​They discussed it The possibility of physical immortality.

Then it came to the conclusion that it is impossible for the human body to live forever, because the human body is constantly aging, and a large part of the reason for the immortality of the main world now is because their bodies are constantly rejecting oxygen after their bodies have regained their youth. At the same time, he has carried out a lot of transformations on himself, allowing human beings to gradually enter the state of internal breathing, and at the same time using the energy of food in the body to realize the circulation in the body, and the intake of oxygen has been reduced to a very low level product.

That's why the so-called altitude sickness and drunken oxygen reaction have disappeared, and because human beings are not healthy now, not many people go to see a doctor, and the hospital is about to be cancelled, so the blood oxygen saturation of human beings, etc. No one cares about anything.

After all, in this era of superhumans, it is meaningless to study these things. Everyone is getting stronger every moment. Before the end of the strengthening, these studies on the human body are meaningless.

So everyone didn't find these things.

But after the Anthropogenic Carboniferous, everyone started to pay attention to this.

After all, in the first generation of gods, there are anti-oxidant free radical gene fragments, and these things are what the main world cares about.

Moreover, in the research on those ancient martial arts figures, it is also found that these people will appear in a state of internal breathing after reaching a certain level. The metabolism of all top masters is very slow, and they have reduced their exposure to the outside world. Whether it is food, water, or appearance, they have reduced their needs, and these have made the main world see it.

Now all these things formed a sentence in the mind of the main world, oxygen is poisonous.

According to all the data, oxygen is a super-powerful corrosive agent. There is nothing in this world that cannot be corroded by oxygen. No matter it is organic or inorganic, they cannot resist the corrosion of oxygen, except for anaerobic bacteria. A relic from ancient times.

Everyone couldn't accept this matter at the beginning, but all the materials were placed in front of their eyes, and they had to accept it if they didn't want to.

However, Zhang Ziyang said that human beings do not need oxygen before birth, which made everyone realize that the fetus does not need oxygen, and all nutrients are transported by the umbilical cord.

Then the bosses saw the cosmic void crossing ability of the second-generation god body, and then everyone had an idea in their minds, and that was it!
