Infinitely increasing attributes, I dominate the multiverse Chapter 356 Earth's past, Poincare

Earth, at the end of the 20th century, Aurora gradually overcame various difficulties in technologies such as room-temperature superconductors, wireless energy transmission, and controlled nuclear fusion.

So overnight, the entire Aurora society ushered in an unprecedented energy revolution.

In the years that followed, the brilliant light ignited by nuclear fusion greatly promoted the development and innovation of Aurora in many fields such as basic physics, engineering, materials science, and semiconductors.

As a result, various high-tech technologies such as fusion energy aviation engines, fluid-free propulsion engines, graphene chips, 6g communication networks, practical quantum computers, cheap anti-tumor drugs, brain-computer interfaces, etc. have also been gradually developed.

The widespread use of these new things and new technologies has completely revolutionized the entire social system of Aurora and brought the dawn of a new era.

Therefore, in the following decades, Aurora also naturally completed multiple comprehensive upgrades of the overall industrial chain.

At the same time, during this period, nuclear fusion energy, an extremely cheap, sustainable, large-scale clean energy, was also fully promoted by the Zhendan country, and gradually overthrew the fossil fuel energy system based on limited resources such as oil, coal and natural gas on a global scale.

In the whole process of the collapse of the old system and the establishment of the new system, the whole world was inevitably filled with a strong smell of gunpowder and a bloody "pain".

Because as the core of a civilization, the change of the energy system will inevitably involve the change of the world's highest "discourse power" or... the sole hegemony.

Therefore, during this period, the huge old economic system that relied on the fossil energy system and the countries built around the old system inevitably had many high-intensity disputes with the Zhendan country involving all levels of society.

There are disputes in the industrial field, disputes in the economic field, disputes in the cultural field, disputes in the aerospace field, and disputes at the level of human race and belief.

There were even fierce disputes in ideology and social systems, as well as the most direct and cruel hot wars in the air, space, land, and sea.

After all parties paid a huge price and suffered a large number of casualties, the final result was the tragic disintegration of the hegemons of the old era and their many vassal states.

The Zhendan Kingdom, standing on the "remains" of many giants of the old era, established the Earth United Government, or the Earth Civilization Alliance, with itself as the main body and various countries around the world as the auxiliary.

But at this time, in the early and mid-twenty-first century, extreme weather events such as sudden rise and fall in temperature, sharp increase and decrease in precipitation, heavy rain, floods, droughts, storms, etc. suddenly appeared around the world.

The frequent occurrence of these extreme weather events has caused extremely serious impacts on the world's economy, transportation, agriculture, industry and social development, as well as people's daily life.

Especially after the growth of crops around the world was severely affected, it directly led to a huge reduction in global food production, which caused food shortages and even regional famines around the world.

Although it did not reach the situation of "a year of famine and cannibalism" at the end of the ancient feudal society, a large number of human tragedies also occurred.

Before human society could catch its breath, large-scale plant species migration, the degradation of nature's regulatory power, the loss of a large amount of biodiversity in various natural areas, and even the inexplicable imbalance and total collapse of the entire natural ecosystem appeared all over the world.

As the saying goes, there must be a big epidemic when there is a big disaster.

Under the dual influence of severe climate anomalies and ecosystem collapse, even the transmission patterns of many diseases in nature have changed significantly.

Even many pathogens themselves have undergone various unknown mutations, which have caused great harm to the health and life of the entire human society.

Therefore, in the entire 20 years since the establishment of the Earth Civilization Alliance, the global population mortality rate has remained high.

In particular, the mortality rate of middle-aged and elderly people has reached new highs every year.

In contrast, the birth rate of newborns has plummeted every year.

What's even more terrible is that many scientists in the Supreme Academy of the Earth Civilization Alliance who are engaged in the human genome decoding and research project have found that the most important gene loss mitigation mechanism in the Y chromosome of human cells, the palindromic sequence, has inexplicably lost its effectiveness.

This means that the Y chromosome, which has no homologous recombination ability, will continue to lose its own genes in the process of reproduction and genetic replication in each generation, and there is no way to alleviate it. In the end, it will only become smaller and smaller or even disappear completely.

With full of fear and anxiety, scientists then compared the genetic conditions of newborns born every year in the past 20 years since the establishment of the Earth Alliance.

After a lot of data research and comparison, they were shocked to find that the situation of the Y chromosome "shrinking" from generation to generation, or the intergenerational "shrinking" rate, is accelerating for no reason.

After summarizing a large amount of relevant data and through detailed calculations and simulations, the anxious scientists came to a conclusion that made them speechless with fear:

If 25 years is a generation, it will only take two centuries and eight generations for the Y chromosome to completely disappear in all human cells.

Although the only important factors that truly determine whether a human is male are a few key genes such as SRY in the Y chromosome, the rest exist only to stabilize the chromosome structure.

So theoretically speaking, it is entirely possible to transfer and splice all these key genes into the x chromosome structure without delaying the expression and presentation of genes.

But theory is only theory after all.

\u003c--\u003e\u003e

br\u003e    It is too difficult to achieve this effect.

If the Earth Alliance has not developed strong enough gene editing technology and strength in the past two hundred years to ensure the safe transfer of all male key genes on different chromosomes across the earth, as well as the subsequent perfect splicing, and the most important gene trait expression.

Then in two hundred years, unless all humans on earth can suddenly evolve into parthenogenetic species, or humans find other new ways of reproduction, otherwise humans on earth will... become extinct.

With a heavy heart, the scientists jointly submitted this thick research report to many senior officials of the Earth Alliance.

The senior officials, who were already exhausted and overwhelmed by many affairs and various problems inside and outside the alliance and on earth, were immediately shocked by this research report from the Supreme Academy of Sciences.

The Y chromosome disappeared? Two hundred years?

Is this a science fiction movie?

Why... does humanity have so many disasters? !

They hurriedly organized a series of high-end scientific conferences, inviting a large number of top scholars closely related to the topic and even masters from unrelated fields to discuss specific solutions or reliable solutions to this serious problem.

Unfortunately, after many meetings and discussions, everyone found that... there was no specific solution or reliable solution at all.

Because with the current technical level of the Earth Alliance, there is basically no particularly effective and reliable way to solve this problem.

At this moment, many astronomers and astrophysicists from the Supreme Academy of Sciences also reported a major discovery to the senior leaders of the alliance.

This discovery is:

After integrating a large amount of observation data and conducting detailed simulation calculations, many scientists determined that the core of the sun has begun to age rapidly for unknown reasons.

In other words, the sun that shines on mankind, which should have only appeared in the red giant stage billions of years later, will undergo a short-term uncontrolled thermonuclear fusion... that is, helium flash, which is about to be staged ahead of schedule.

The so-called helium flash is a sign that a star is entering old age, and it is also the last glory of its main sequence stage.

In essence, the hydrogen in the core of the star is burned out, and then the helium, which is heavier than hydrogen, will fall into the core of the sun under the influence of gravity, replacing the original hydrogen.

At the same time, the nuclear fusion of helium is much more violent than that of hydrogen, and the energy released is also much larger.

In this process, in order to maintain the balance of gravity and pressure, the volume of the sun will expand rapidly.

After the helium flash, the surface activity of the sun will be more intense, releasing more intense radiation.

Most importantly, the extremely explosive sun will even engulf the entire earth's orbit.

As for the earth civilization and all mankind in it... maybe they will be evaporated in a very short time.

At the same time, other scholars of the Supreme Academy of Sciences also seriously pointed out that after integrating a large amount of data, including the change data of human Y chromosomes, the change data of the earth's internal and external magnetic fields, the change data of the solar magnetic field, and the change data of the frequency of solar light.

They speculated that the various disasters that have occurred on Earth in the past two decades, including the abnormality of human Y chromosomes, are most likely related to the rapid aging of the core of the scorching sun billions of kilometers away.

In other words, it is the abnormal stellar magnetic field and light radiation of the sun that has quietly undergone a dramatic change that has caused all of this.

…

"The experience of Earth civilization in the last era feels very similar to the background story of the movie "The Wandering Earth".

Although the Chinese country in the movie is not as strong as the Zhendan country, it can actually unify the world.

Well, then these Zhendan people must have experienced certain events to become the hungry gods.

Otherwise, with their technological level that is a million miles away from the most basic interstellar civilization, no matter how hard they try, they can't solve this civilization disaster involving changes in the sun's interior."

Mu Cang "flipped through" the information sea that was gathered from all the memories of the hungry gods and thought leisurely, "But... in the nineties, they were able to develop a universal controlled nuclear fusion technology, and roughly completed global unification in the middle of the twenty-first century... This does seem a bit too fast."

This suddenly reminded him of an anime he had watched in his previous life... "Leap to the Top."

What impressed Mu Cang the most about that anime was that in its plot setting, the human civilization on Earth could actually master superluminal space travel technology in the early twenty-first century.

It's simply outrageous.

By the way, among these vast amounts of information, Mu Cang has already confirmed that the Hungry God Clan was born in the Orion Arm Solar System Earth Human Civilization in the Milky Way Galaxy in the last cosmic era before the birth of this universe.

That time period is hundreds of billions or trillions of years away from now, or even longer.

"Well, after all, it is the Earth civilization of the last era, and its nature is similar to that of parallel time and space, so whatever happens is possible."

Mu Cang, who was as huge as a giant in the universe, sat cross-legged in the boundless void, thinking quietly, "But... why did the earth civilization also appear in the last era? Moreover, the culture, race, history, and even various entertainment elements... movies, animation, games, and music are so similar or even the same. Why is this? Could it be... Poincaré Regression?"

The so-called Poincaré Regression or Poincaré Reappearance is essentially a mathematical theorem, not a physical law that needs to be verified.

As far as the Poincaré Regression Theorem itself is concerned, it has little to do with whether the universe can be reproduced.

The important reason that can make them connected--\u003e\u003e

is that some physical laws and rules of the objective real universe happen to meet the conditions for the establishment of the Poincaré Regression Theorem.

However, similar phenomena do exist in the field of physics, and they are also named "Poincaré".

That is: a finite closed isolated material motion system that is not affected by external forces will inevitably perform periodic internal motion.

This is called the initial state recurrence theorem, which can also be called the Poincaré Regression Theory.

In addition, there are also predictions of phenomena similar to Poincaré regression in M-theory:

M-theory believes that the universe can spontaneously emerge from nothingness.

Even if the universe continues to cool and sparse indefinitely as it currently does, it will be diluted to the point where all baryonic matter falls into black holes and is converted into Hawking radiation.

In the future space that is extremely far away and close to quantum vacuum, a quantum-scale universe can randomly emerge again and explode into a new universe.

And M-theory believes that this emergence can occur any number of times.

At the same time, in any given finite large-scale universe, the combination of matter, energy, and information is limited.

Then, based on the previous conclusions and the speculation of Poincaré regression, a new summary conclusion can be drawn:

That is, if the real universe where Mu Cang is located complies with M-theory and the initial state recurrence theorem, then it can occur and any number of Poincaré regressions can occur.

And after it happens enough times, the speed of light in the universe between two times can be consistent, chemical bonds can be re-established according to the distance between atoms, the Milky Way can reappear, and human civilization... can also be born again.
