Road to science and technology

Based on this result, Yue Yuanzhou knew that the owner of this light was moving away from him at an extremely fast speed. This is when the speed of space-time expansion reaches a very frightening level.

This is too exaggerated. Yue Yuanzhou now believes that if his guess is correct, this dark universe is a universe that is almost dead, one that will be lost in the infinite expansion of time and space.

"This is really desolate, but at least there is light now, so let's follow the direction of the light and have a look."

Yue Yuanzhou sighed, then started warp sailing and drove towards the target. Since the space-time of this universe has been stretched and flattened by the repulsive force of dark energy to an incredible extent, the relative thrust obtained by the partial function of dark energy flattening space during Yue Yuanzhou's warp voyage has been very weak, so now he is basically 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 the speed of light.

During the voyage, Yue Yuanzhou was not idle. He waved his hand directly in front of Ah Zhui and Karl, used the light of Taihu Lake to bring up 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 previously observed cosmic data and the theory of cosmic evolution. At this time, Yue Yuanzhou raised his hand and clicked on this huge virtual projection.

"look!"

Yue Yuanzhou said something, and then in the eyes of Chai and Karl, 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 a very large scale, so the scene quickly switches to the birth of the first star.

Immediately afterwards, countless nebula materials filled the simulated universe, and more stars were born at this time. Time is still going on. After just one breath, these stars are attracted to each other's gravity, or collide and collapse to form the original black hole. The black hole continues to swallow up interstellar dust and even stars close to it, so its mass becomes larger and larger. , so it can bind more and more stars, and galaxies are formed.

The simulation time continues, and countless galaxies form vast galaxy clusters and superclusters. During this period, they either collide to form larger galaxies or larger black holes. Immediately after the first generation of stars died, the second generation of stars reborn from the ashes of their debris and illuminated the universe again.

From the Big Bang to the present, twenty billion years have passed in the simulation. The second generation of stars have also died one after another. They have evolved into white dwarfs, followed by red dwarfs, stars with a lifespan of close to a trillion years, and they have also begun to die one by one. .

Now all the stars in the simulated universe are about to burn out, and the universe is gradually entering eternal night.

At this time, Chase couldn't help but asked: "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 still be a lot of cosmic ray radiation, but this is not the case in the universe we observe. Let's continue to 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 trace of light disappeared, and the universe finally turned dark.

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

Twenty billion billion years later, when the last star dies, it marks that the evolution of this simulated universe has entered the degeneracy era. White dwarfs emit white light, which is less than one millionth as bright as 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 things in the universe are the corpses and remains of stars. They are soupy and dense corpses. After the simulated universe enters the degeneracy era, billions of years have passed. Due to 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, with cooled black dwarfs buried everywhere, as well as countless black holes hidden in the void and neutron stars invisible to the naked eye. They are like noble tombs in the tomb. Full of all kinds of things. dangers and traps.

And just when its viewers, Karl and Azui, thought the universe was dead, an extremely unlikely event appeared on the simulation screen.

Two surviving brown dwarfs, which still represent the last hope of the universe, attracted each other by chance and then collided together. So 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, but it still jumps when the nerves in its legs are stimulated. It always makes people think that this is the illusion that it is still alive.

When he saw this, Yue Yuanzhou said: "This may be the time point of the current universe, hundreds of millions of years after entering the degeneracy era, and the light of the stars detected before may be as small as the simulation just now. The last stars formed by the collision of brown dwarfs. We have not detected gravitational waves, indicating that it has been a long time since their collision, the gravitational waves have calmed down, and the stars have stabilized. We are now going to see what these last lights are like Kind of."

"Will there be life?"

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

Yue Yuanzhou knew that in fact, they entered this universe and just appeared here, and then detected a ray of light from this star. This was a miracle in itself. If they did it again or even countless times, they would not be able to detect anything luminous.

Karl couldn't help but sigh. He didn't know how many times he had sighed in this time: "Yes! If life is really born at this time, then how sad they are. They can't explore the universe, and they don't have the energy to go to the stars." Sailing, they will be trapped forever in the cradle where their lives were born and the last harbor in the universe, lingering."

As a knowledgeable scholar, Karl knew very well that the last star born from the collision of such debris alone would most likely be nothing more than a small red dwarf. The energy of a star would not be able to support a civilization in exploring the universe.

Because the universe at this time is obviously very far away from heat death, and the nearest stars that were born in this way may be tens of billions of light years away from each other. A distance of death that no civilization can cross.

"Yes, but we can't rule out miracles. Our trip itself is a miracle." Yue Yuanzhou frowned as soon as he finished saying this. Miracle?

Since miracles are possible, we cannot rule out the possibility that the civilization born in the universe can still survive today after developing into a god-level civilization!

Thinking of this, he immediately took a breath of cold air, then immediately activated all the concealment methods of Shenzhou Star, and then prepared the upgraded and strengthened three-piece running set to the pre-activation state.

After doing all this, he still couldn't help but be curious and wanted to see this star, but since then his heart has become wary, because he is not sure now that this is an enhanced version of its power in his opinion. Whether the three-piece suit can work against a god-level civilization.

But on the other hand, he was also thinking that it was possible that they had all been destroyed by time or left, but the greater possibility was that they were traveling in time.

"It seems unlikely. The universe is like this. If they are still here, they should come out and take care of it, because it is obvious that if this universe continues like this, it will be infinitely dead!" Yue Yuanzhou touched his chin and thought.

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

Then take another look!

Several hundred years passed after Yue Yuanzhou's decision, and they finally arrived at their destination, the last star!

Several light-years away from the star, Yue Yuanzhou quietly released the detector, and then asked the following Taotie civilization and Proxima Centauri civilization to enter a state of communication silence and use all their hiding methods to wait for the detection results of the detector.
