The road to technology

Chapter 203 Cosmos Degeneracy
According to this result, Yue Yuanzhou knew that the owner of this smear was heading towards him at a very, very fast speed.This is the speed at which space-time expands to a frightening level.

This is too exaggerated, Yue Yuanzhou now believes that if the guess is correct, this dark universe is a universe that is already dying, one that will be lost in the infinite space-time expansion.

"This is really desolate, but at least there is still light, so let's look in the direction of the light."

Yue Yuanzhou sighed, then started warp speed sailing towards the target.Since the time and space of this universe have been stretched and flattened by the repulsive force of dark energy to an unbelievable level, the relative thrust obtained by part of the functions of dark energy to flatten space during Yue Yuanzhou's warp speed flight is already very weak, so now basically he It can only use the distorted space-time of the warp crystal as power to drive towards the target at a relative speed of about 250 times.

During the voyage, Yue Yuanzhou was not idle. He waved his hand in front of Ah Zhui and Karl, and used the light of Taihu Lake to call out a simulated universe model, and then input various parameters and set various data. , with his skillful operation, the universe simulation is ready.

Although it is a simulation, these data are based on the previously observed data of the universe and the theory of the evolution of the universe. At this time, Yue Yuanzhou raised his hand and clicked on this huge virtual projection.

"Look!"

Yue Yuanzhou said a word, and in the eyes of Ah Zhui and Carl, the projection screen began to change.

A singularity appears, and then the singularity expands in an instant, light, heat, and the most basic quarks are formed, and material space and time are formed.The physical quantity of time in this simulation is accelerated to very large scales, so that the scene quickly switches to the birth of the first stars.

Immediately afterwards, countless nebula materials filled the simulated universe, and more stars were born at this time.Time is still going on, just after a breath, these stars are attracted to each other by the gravitational force of each other, or collide and then collapse to form the original black hole, the black hole continues to swallow the interstellar dust and even stars close to it, so its mass is getting bigger and bigger , so it can bind more and more stars, and galaxies are formed.

As simulation time continues, countless galaxies form vast galaxy clusters, superclusters, during which they either collide to form larger galaxies or form even larger black holes.Immediately after the death of the first generation of stars, the second generation of stars rose from the ashes of their wreckage, re-lighting the universe.

From the big bang to the present, the simulated time has passed 200 billion years, and the second generation of stars have also died one after another. They evolved into white dwarfs, followed by red dwarfs, stars with a lifetime of nearly trillion years, and they also began to die one by one.

Now simulate that all the stars in the universe are about to burn out, and the universe gradually enters the eternal night.

At this time, Ah Zhui couldn't help asking: "Is this the stage of the universe we are in now?"

"Maybe not, because there are still a lot of white dwarfs at this time, so there should be a lot of cosmic ray radiation, but the universe we observe is not the case, let's see."

After Yue Yuanzhou finished speaking, the simulation screen continued to change. At this time, the last red dwarf star also died and turned into a brown dwarf star. The last ray of light disappeared, and the universe finally became completely dark.

At this time, Karl said with emotion: "The ultimate of the universe may not be a big bang, but a whimper!"

After 200 billion billion years, when the last star also dies, it marks that the evolution of the simulated universe has entered the degenerate period.White dwarfs emit white light, whose brightness is less than one millionth of that of the sun. This light is the emission of the remaining energy of the star, but it is no longer enough to illuminate the universe.

At this time, the only thing in the universe are the corpses and wreckage of stars, they are soupy and dense corpses.After the simulated universe enters the degenerate period, billions of years have passed. Due to the lack of fuel, the white dwarf will gradually dim. It will lose its last afterglow, turn black and cold, and die again.

The simulated universe is now a huge cemetery, where cooled black dwarfs are buried everywhere, and there are countless black holes hidden in the void and neutron stars invisible to the naked eye. They are like the tombs of nobles. dangers and pitfalls.

And just when its viewers, Karl and Ah Zhui, thought that the universe was about to die, an extremely extremely low probability event appeared on the simulation screen.

Two lingering brown dwarfs, the last hope of the universe, attracted each other by chance and then collided.So a new hope was born. Two brown dwarfs collided and formed a new star. Light and heat once again illuminated the tip of the iceberg in the universe.

This ray of light is like a frog that has been completely dead for a long time, jumping up and down when the nerves in its legs are stimulated.It always makes people think that this is an illusion that it is still alive.

When he saw this, Yue Yuanzhou said: "This may be the time point of this universe, after entering the degeneracy of countless billions of years, and the light of the stars detected before may be as extremely unlikely as the simulation just now." The last stars formed by the collision of brown dwarfs. We have not detected gravitational waves, which means that they have collided for a long time, the gravitational waves have calmed down, and the stars have stabilized. We are going to see now, what are these last rays of light? kind of."

"Will there be life?"

Regarding Ah Zhui's question, Yue Yuanzhou shook his head and sighed: "It is almost impossible for a star born in this way to give birth to life. Everything is possible to be born. If it is really born, it will be the greatest miracle in the universe. There is no one. .”

Yue Yuanzhou knew that in fact, they entered this universe and just appeared here, and then detected a gleam of light from this star. This is a miracle in itself. If they do it again or even countless times, they may not be able to detect any luminous things.

Karl couldn't help feeling, he didn't know how many times he had felt in this period of time: "Yes! If life is really born at this time, how sad they are, they can't explore the universe, and they don't have the energy to go to the interstellar world. Sailing, they will be trapped forever in the cradle where their lives were born and also the last harbor in the universe... lingering."

As a knowledgeable scholar, Karl knows very well that the last star born by the collision of such wreckage alone is likely to be a small red dwarf, and the energy of a star cannot support a civilization to explore the universe.

Because the universe at this time has obviously gone a long way on the road to heat death, and the nearest stars born in this way may be tens of billions of light-years away from each other. A death distance that civilization cannot cross.

"Yes, but a miracle can't be ruled out. Our trip itself is a miracle." Yue Yuanzhou frowned as soon as he finished speaking, miracle?
Since there may be miracles, it cannot be ruled out that the civilization born in this universe has survived to this day after it has developed to a god-level civilization!
Thinking of this, he immediately took a deep breath, and immediately activated all the concealment methods of the Shenzhou star, and then prepared the upgraded and strengthened running three-piece suit to the pre-activation state.

After doing all this, he still couldn't help being curious and wanted to see this star, but since then his heart has also become vigilant, because he is not sure that this is already a more powerful version in his opinion Whether the three-piece suit can work against a god-level civilization.

But on the other hand, he is also thinking, it is also possible that they have all been destroyed by time or left, but it is more likely that they are traveling in time.
"It seems unlikely. This universe is like this. If they are still there, they should come out and take care of it, because this universe is obviously going to be infinitely dead if it continues like this!" Yue Yuanzhou rubbed his chin and thought.

There is another reason why Yue Yuanzhou didn't want to run away after thinking about the possibility of a god-level civilization. That is, he felt that this was just the perfect place for the experiment he had always wanted to do.

Then look again!
Hundreds of years passed after Yue Yuanzhou made his decision, and they finally arrived at their destination, the last star!

A few light-years away from this star, Yue Yuanzhou quietly released the probe, and then put the following Taotie civilization and Proxima civilization into a state of communication silence and fully opened their concealment methods, quietly waiting for the detection results of the probe.
