In fact, the main world also has its own speculations about the void in the universe.

If we take the Earth as the center, then the surrounding universe with a scale of one billion light years, that is, the local supercluster, is composed of many holes and filaments.

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

So in some places, matter is slightly denser, and in other places, it's less dense. Areas with greater density have greater gravitational pull, causing them to clump together more. Conversely, areas with lower density have less gravitational pull.

, the less people gather.

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

Here it is.

According to the study of the cosmic redshift phenomenon, it is clearly shown how the high-matter-density region shrinks under the influence of collective gravity 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 conducted an experiment in a universe with an unknown time span.

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

That is to say, I have artificially created a void in the universe, and I want to see if my theory of the void in the universe is correct.

Although this experiment has just started not long ago, the high matter density area has already begun to absorb the matter from the low matter density area through gravity. According to the calculations of the main world, in about tens of thousands of years, there will be a large area with five

A light-year void in the universe.

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

But these have nothing to do with the super-god world. In this world, people don’t know much about cosmology and the technologies of aerospace-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 the aerospace-level civilization, in their view, it is a transitional period, or an era that inspires god-level civilization.

In the era of civilization, it was not a big deal. It was so common in the universe that no one thought it was a big deal.

But in fact, aerospace-level civilization is the main civilization in other worlds, and the so-called post-nuclear civilization is called a remnant of civilization or a survivor of civilization 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 constantly being born, then the development of this civilization will be normal.

Without population, there is nothing. This is a wise saying in the development of civilization in the universe. Population is everything.

According to the views of all known aerospace-level civilizations, the development path of god-level civilizations in the super-god universe is wrong. Pursuing personal power has no meaning at all. Only the power of the whole people can be truly powerful.

Therefore, from the beginning, the main world did not expect to see the super-god world, if it were not for the longevity of the ladder computer and the first-generation god body, the radiation immunity, and the ability of the second-generation body to resist the Great Peace, as well as the physical body to cross the universe.

These abilities really make the main world a little jealous.

But now the focus of the main world has shifted from the longevity and radiation immunity that were most seen before, to the physical body crossing the void of the universe, because on many habitable planets, the main world has not found traces of oxygen.

It's as if oxygen is unique to the earth.

However, the main world had no idea about these things in the past. The most important thing is to transform it. Release a large amount of algae on a livable planet with water, and it will naturally transform it into a planet suitable for human habitation.

However, during this period of transformation, the main world discovered some things, which made the main world feel that something was wrong.

When a certain planet was being transformed, a large number of algae organisms and a large number of genetically modified rapid green plants were used to transform the planet into a Carboniferous Earth in a short period of time, with the oxygen concentration reaching as high as 35

% or more, then the Carboniferous coal-burning event occurred. However, it is not so much a coal-burning event in outer space as it is a spontaneous combustion event in the rainforest.

This incident opened the minds of everyone present. They named the incident an artificial Carboniferous incident and reported it to the central research laboratory in the main world.

Then there was an idea in the central research laboratory, why the earth is special, other planets do not have that much oxygen content, oxygen is not a necessity in other worlds, but is used as a corrosive agent

,why is that?

Then everyone began to discuss oxygen, and the main discussion focused on oxygen free radicals.

In medicine, everyone knows the harmfulness of oxygen free radicals. When the human body suffers severe trauma such as trauma, poisoning, or major surgery, excessive bleeding, the tissues of the human body will be in a state of hypoxia, energy metabolism will be disordered, and cells will be damaged.

Pigment oxidase is unable to reduce oxygen to water, and the oxygen atom will be deprived of an electron, turning harmless oxygen into a lethal reactive oxygen free radical. Oxygen

The peroxidative killing of free radicals mainly destroys the structure and function of cell membranes, damages mitochondria, cuts off the cell's energy source, destroys lysosomes, and causes cell autolysis. At the same time, it also has a harmful effect on the non-cellular structures of the human body, and can damage the blood vessel wall.

The adhesive on the blood vessels is damaged, causing the completely sealed blood vessels to become riddled with holes, causing bleeding and exudation, which in turn leads to edema, purpura, etc.

Similarly, when the coronary arteries that supply blood to the heart suddenly spasm, myocardial cells will undergo a series of metabolic changes due to hypoxia. The antioxidant content in the myocardial cells is reduced, causing the chemical reactions that generate oxygen free radicals due to the hypoxic state.

At a relatively accelerated rate, the moment the coronary artery spasm disappears, the myocardial cells are suddenly re-perfused with blood.

, then a large amount of oxygen is converted into oxygen free radicals. At the same time, due to the relative lack of antioxidants, the oxygen free radicals cannot be scavenged. As a result, the highly lethal oxygen free radicals seriously damage the myocardial cell membrane, and a large number of ions are released from the myocardium.

Overflow within the cells, and the latter can disrupt the electrical signals that control the heart's pulse, causing ventricular fibrillation, leading to death.

Aging is also caused by oxygen free radicals. Oxygen free radicals can attack the fatty acids on the cell membrane, thereby producing peroxide. This substance is a highly toxic substance that can damage nucleic acids, proteins, etc. in the body and cause

A series of cell damaging effects, the more oxygen free radicals accumulate in the human body, the faster the aging process. The common age spots on the faces of the elderly are caused by the oxidative decomposition of lipids by oxygen free radicals to form malondialdehyde.

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

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

For these things, the main world has also found many beings who have abandoned their physical bodies, such as the immortals in the Third World of God, as well as Huainan King Liu An from Marvel, and big-shot figures like Zhang Ziyang. They discussed it for a while

The possibility of physical immortality.

The conclusion then drawn is that human immortality is impossible because the human body is constantly aging, and a large part of the reason for immortality in the main world now is because after their bodies have regained their youth, their bodies are constantly rejecting free oxygen.

At the same time, he has carried out a large number of transformations on himself, allowing human beings to gradually enter a state of inner breath. At the same time, he has used the energy of food in his body to achieve circulation in his body, and his oxygen intake has been reduced to a very low level.

Tasted.

That’s why the so-called altitude sickness and oxygen-induced oxidative stress have disappeared, and because humans are now too healthy to be healthy, not many people go to see a doctor, and hospitals are about to be cancelled, so human blood oxygen saturation and other

No one cares about anything anymore.

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

So no one has discovered these things.

But after the anthropogenic Carboniferous Period, everyone began to pay attention to these.

After all, there are anti-oxidant and free radical gene fragments on the first-generation divine body. These things are what the main world cares about.

Moreover, in the research on those ancient martial arts figures, it was also found that these people will enter a state of internal breathing after reaching a certain level. The metabolism of all top masters is very slow, and they have reduced their response to the outside world.

Whether it is food, water, or appearance, they have reduced their needs, and these have been noticed by the main world.

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

According to all the information, oxygen is a super powerful corrosive agent. There is nothing in this world that cannot be corroded by oxygen. This is true whether it is organic matter or inorganic matter. It cannot resist the corrosion of oxygen, except for anaerobic bacteria.

A remnant of ancient times.

No one could accept this at the beginning, but all the information was placed in front of them, and they had to accept it if they didn't want to.

However, Zhang Ziyang said that humans actually 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.
