() This cosmic bubble "blown" by the high temperature and rapid gas flow of the huge star is very huge. Estimated based on its distance, the diameter of the cosmic bubble is about sixty light years. As far as the giant star itself is concerned , the Shouguang star emits bright blue light near the center of the nebula. The mass of the Shouguang star is more than thirty times the mass of the sun. We believe that it is in a brief pre-explosion supernova stage in the evolution of supermassive stars. The rapid blast of the Shouguang star The bubble-shaped nebula was formed by gas currents that blew away slower-moving material produced in earlier stages of evolution. The nebula, blown out by stellar gas currents, is about 90,000 years old.

Then, Xu Qianming began to think and wrote the following three universe hypotheses in his notebook:

"Hypothesis 1. There was an inflationary process when the universe was born. The time was very short, just a tick, and then it switched to expansion at a normal speed. The above process has basically been confirmed by the scientific community, but no one has noticed that this sudden change in speed is To produce rebound contraction, it is a solitary wave of longitudinal wave nature. It will definitely reflect at the boundary of the hyperspherical universe, sweep into the inner universe and oscillate multiple times. The period of this solitary wave is extremely short when it is first generated. , it may be discretized and elongated after billions of years. But it will certainly not be too long, for example, no more than a hundred years. This solitary wave does not start in a certain region of the universe, but starts in the entire universe at the same time. Its synchronicity is also determined by its intrinsic nature. Theoretically, this solitary wave should have swept through the universe many times.

"Hypothesis 2. In the very early days of the Big Bang, there was a short period of inflation. This period of inflation lasted about ten to thirty seconds. After that, the size of the universe doubled approximately every ten to thirty seconds. Because of this This kind of inflation smoothed out all the original unevenness of the universe. The cause of the inflation is believed to be caused by the existence of huge energy and pressure in a very small area. A region the size of a subatomic particle, due to accidental The reason may be such a high-intensity energy field. Our universe may be the continuous expansion of an energy field in a long-existing universe-the metaverse. In the metaverse, there will be many Such high-intensity energy fields may expand into a universe at the same time or one after another. It is like a cauldron that is boiling glue, with many bubbles popping up simultaneously and continuously. In our universe, also Such a high-intensity energy field may be generated, thus giving birth to a new universe.

"Hypothesis 3. The spontaneous creation of the universe is a bit like the formation of bubbles in boiling water. The origin of the universe is a bit like bubbles in boiling water. Many small bubbles appear and then disappear. This is the expansion and collapse of the universe. There were many universes before All disappeared. When these small bubbles expanded to a certain size and could safely escape collapse, our universe today was formed. Each universe has a different shape, but each individual universe is called a bubble. The bubbles will move freely and even collide with each other. Where these cosmic bubbles collide with each other, they will leave traces in the background radiation.

Xu Qianming's three hypotheses were affirmed by several uncles and aunts.

Ever since Xu Qianming boarded Qiongyu No. 1, Li Tianyou had been keeping his head down and meditating, and no one disturbed him.

At this time, Li Tianyou raised his head and said to himself: "The scale of the universe is at least 15 billion light-years, and it is impossible to change from expansion to contraction at the same time. This is based on a generally recognized assumption in the scientific community, saying It’s an axiom, that is: no matter what the factor that can cause the universe to change synchronously, its propagation speed cannot be higher than the speed of light. Cosmologists have long used this consensus in practical work. For example, if you observe If a distant galaxy becomes brighter overall within ten years, then the size of the galaxy will never be larger than ten light-years."

What Li Tianyou said was a rule that everyone knew. Xu Qianming was not convinced and boldly raised a question: "Uncle Li, I know this rule, but the phenomenon I want to talk about is not among them. If there is a completely uniform balloon, If the balloon is inflated by a completely uniform high-pressure airflow, then of course when the elasticity of the balloon and the internal pressure are balanced, each area of ​​the balloon will stop expanding at the same time, even if it is as big as 15 billion light years. Let's take the axiom you mentioned a little bit To supplement: No matter what the factor that causes the synchronous change of the universe, its propagation speed cannot be higher than the speed of light, except for changes caused by the intrinsic nature, the intrinsic synchronous state is not limited by the maximum speed of light. Uncle Li, I can make an analogy: this is like twin particles in quantum theory. They form a related system. The observation of one particle can instantly cause the other particle to choose the 'correct' state. This effect is over a distance. , is not limited by the maximum speed of light. The Hubble Telescope has determined that the universe is isotropic, that is, it is intrinsically uniform."

Li Tianyou was shocked by Xu Qianming's bold suggestion and fell silent.

After a while, Li Tianyou raised his head, looked at Xu Qianming solemnly, and said: "If...as long as...you admit your axiom, then your hypothesis...can still be self-consistent. It also solved a logical difficulty—— The collapse center, that is, the black hole, must happen to have a patrol speed of 220 kilometers per second. Because if the universe is shrinking as a whole, the presence or absence of this speed does not affect the observed values. Qian Ming, your thinking is very active and unconstrained. .It’s rare.”

But Li Tianyou was obviously still reluctant. He said frankly: "But to be honest, I still don't like this hypothesis. It also has the flavor of 'anthropocentrism'. Now it is not the center in space, but in time." ——In the 15 billion years of expansion of the universe, how come we happen to catch up with the moment when the universe begins to shrink? What a coincidence." At this point, Li Tianyou shook his head and continued: "But this There is not much power in rebuttal. There are still coincidences in the world and cannot be denied outright. Let’s think about it again.”

Then, there was silence in the main control room. Xu Qianming and Li Tianyou both thought silently, like old monks practicing in seclusion.

Wang Tingting later felt that something was wrong. She finally couldn't help it and asked Li Tianyou cautiously: "Tianyou, what happened? I think your and Qian Ming's expressions are not right."

Li Tianyou smiled and said: "It's nothing. The new idea proposed by Qian Ming may be right, but it is unlucky - even more unlucky than the original idea. We originally thought that the universe was partially collapsed, so in 100,000 Years or hundreds of thousands of years from now, human beings may still be able to escape from this hell with their technological level; now Qian Ming says that the universe is shrinking as a whole, so where can humans escape? No matter how advanced the technology is, there is nowhere to escape."

"What does this have to do with it? Cosmologists have long said that the universe will eventually perish."

"Yes, some cosmologists hold such a theory, but this is only at the stage of hypothesis. Cosmologists who hold this hypothesis are talking about the 'natural age' of the universe, and death is after billions and tens of billions of years. thing; and now Qian Ming says that our universe is suffering from a terminal disease and will die in hundreds of thousands of years... Sigh... the new lifespan of the universe is only one ten thousandth of the original 'day year'."

Wang Tingting's expression also paused for a moment, but she immediately changed her mind: "That's nothing, there are still hundreds of thousands of years. People can still live for hundreds of thousands of years, and they are still far from extinction."

"The universe is terminally ill" is just a hypothesis of Xu Qianming. What he never expected was that a week later, an unknown person would spread the news that the universe was terminally ill. The news spread all over the world and shocked the world. The world of cosmology The reaction outside was even stronger than inside the circle.

Not to mention those wise men and philosophers who often have "apocalyptic worries", even ordinary people are like swarms of bees that have been plucked from their hives, and they are in a mess: The sky is going to fall? Is it really going to fall? Is humanity really going to fall? Nowhere to escape? The cults and groups that preached the end of the world in many countries were given a shot in the arm, and they began to recruit troops aggressively, and organized seven or eight mass suicides of believers, with the largest number of people reaching eight in one case. More than a thousand people.

With the refutation of the rumors by the space agencies of various countries, people have emerged from the shadow of the end of the world and returned to normal lives.

At this time, an Earth-like planet appeared on the big screen in the Qiongyu-1 main control room. Through the big screen, you can clearly see that this Earth-like planet has rivers and lakes, virgin forests, grasslands, and various xing life.

This earth-like planet is inhabited by human beings whose appearance and shape are different from those on earth. It is named Qianyuan Star, or Qianxing for short, by the humans on the planet.

This Earth-like planet is closest to Earth, one-tenth of the distance of the Moon.

Although Qianyuan Star is much closer to the earth than the moon, it revolves around the sun like the earth and is a planet, unlike the moon, which revolves around the earth. The moon is still the only natural satellite of the earth.

A village appeared in the center of the big screen, and a girl of twelve or thirteen years old was playing outside the village riding a green pet beast.
