Start with a planet hitting the earth

The entire neutron star was swallowed up by Chen Yuan.

The volume of Chen Yuan is slightly larger than before, and is now about 2.9 times the diameter of the sun.

And its mass is currently 7.3 times that of the sun.

To become a black hole, Chen Yuan still needs 142.7 times the mass of the sun.

"It feels a lot bigger, but forget about the neutron star. It's too risky. Find some other celestial body to devour it."

Chen Yuan originally thought that he was massive enough, so he wanted to challenge a neutron star. Now he has indeed tried it.

That turned out to be a bit fatal.

If it weren't for Youya's reminder, Chen Yuan would have planned to run away, and if he ran away, it would be equivalent to gaining some mass from the neutron star in vain.

Fortunately, Youya reminded me, otherwise I would have suffered a huge loss.

As for how Ya knew that the neutron star could not swallow Chen Yuan before Chen Yuan approached. Chen Yuan knew this without thinking too much.

The civilization where Ya lives is an advanced civilization. It is a civilization that plans to create a new universe. It is naturally very easy for such a civilization to use some data calculations to determine whether the neutron star can swallow Chen Yuan before Chen Yuan approaches. thing.

Of course, Chen Yuan himself didn't know. He could only judge based on his own intuition.

Chen Yuan's intuition told Chen Yuan that neutron stars were much scarier than the previous white dwarf stars.

Chen Yuan didn't think too much and turned on his perception ability.

Find your next target.

Anyway, except for these two things, neutron stars and black holes, let’s talk about other goals.

The closest and most suitable target is a red dwarf star.

Fifteen percent of the Sun's mass.

"Too few..., forget it, just swallow it all the way, and use the red dwarf star as a transfer station." Thinking of this, Chen Yuan locked the direction of the red dwarf star and set off there.

Not long after Chen Yuangang started, a burst of bright light attracted his attention.

Through his perception ability, Chen Yuan could see the bright halo emitted by the star explosion.

The reflected light is all the tiny matter emitted after the star exploded.

Is it the tiny matter left behind when a supernova explodes?

Seeing this, Chen Yuan had an idea.

"Could it be that the source of dust in the universe comes from supernova explosions?"

Chen Yuan didn't know this, it was just his guess.

"Cosmic dust comes from supernova explosions, and then the dust gathers into dust clouds. The dust clouds give birth to stars, and when the stars evolve to the end, there is another supernova explosion... Is it an infinite cycle?"

Chen Yuan was thinking.

"Indeed, most of the current cosmic dust comes from supernova explosions. However, an infinite cycle is unlikely." Yana's unique neutral female voice came, and she said with great interest: "In the universe, Hydrogen and helium will also be consumed. One day, both elements will be used up. "

"Without hydrogen and helium, it would be impossible for the universe to give birth to stars." Ya said with a playful smile: "To put it simply, after those two elements are consumed, the universe will no longer see light. , there will be endless darkness left.”

"So, there is no way to loop infinitely."

"Will the hydrogen and helium elements be exhausted?" Chen Yuan thought subconsciously. This was something Chen Yuan did not expect.

"Of course, after all, hydrogen and helium elements are burning and being consumed every day." Ya said: "Since they will be consumed, they must be consumed one day. After all, in the universe, hydrogen elements will not increase. ”

"But don't worry. Once the hydrogen and helium elements are used up, I don't know how many billions of years will pass."

Listening to Yana's indifferent speech.

Chen Yuan fell into deep thought.

If the hydrogen and helium elements in this universe are gone, it means that this universe will completely lose its light.

Stars will also disappear and all become black dwarfs, neutron stars or black holes.

"Then the entire universe is just the remains of stars?" Chen Yuan thought subconsciously.

A black dwarf is a completely dead star that has evolved from a white dwarf. It can be said that it is the corpse of a star.

Neutron stars and black holes are essentially dead stars.

"Well, it can be said that by that time, if we haven't discovered the edge of the universe and moved away from this universe, then we will be finished."

"Do you want to know what will happen to the Milky Way by that time?" Ya said softly.

Ya is very leisurely, and when she is free, she always wants to talk to Chen Yuan.

Chen Yuan said: "How is it?"

Ya said playfully: "Except for some matter thrown out by other factors, all other matter will be swallowed up by the largest supermassive black hole in the Milky Way. Until the entire Milky Way, only the supermassive black hole remains until."

"After that, there will be only a bunch of black holes left in the entire universe, and those black holes will orbit the massive black holes until they are swallowed up."

"That's really scary..." Chen Yuan felt like his soul was trembling as he listened to Ya's speech.

When that time comes, there won't be any life in the entire universe.

"But don't worry. When that time comes, I can take you to the new universe, and let it be destroyed here." Ya said casually.

Chen Yuan said: "I don't think about it anymore. If I keep thinking about it, the universe will probably be gone."

"Haha." Ya smiled.

Chen Yuan's eyes fell forward and continued to fly forward.

"There is a civilization ahead. According to your current trajectory, it will not have any impact on them." Ya reminded softly.

Civilization is highly intelligent life.

"Life? The universe was originally lifeless. So is life also a kind of matter?"

"Of course, cell genes, if you look at it from the surface, are a fusion of various substances." Ya talked to Chen Yuan with interest.

According to scientists, the human body is composed of various elements, and elements are a kind of matter.

Life comes from planets.

And stars and planets all originated from dust clouds.

Dust clouds are formed by the accumulation of dust.

In other words, life is composed of dust.

"The universe gave birth to stars and planets, and gave birth to life. And now life is looking for the edge of the universe, leaving the universe, and creating the universe outside." Ya smiled softly and said, "The relationship between the universe and life is really wonderful."

"It's really wonderful."

Chen Yuan didn't think about it anymore and continued to fly.

I don't know how much time it took.

Chen Yuan saw his goal.

What will happen in the future is not important. The important thing now is that I have to swallow this red dwarf first.

Chen Yuan has already seen his target.

The red dwarf appeared in front of Chen Yuan.

At this moment, Chen Yuan is already a blue dwarf, so it is easy for him to swallow the red dwarf.

No need to follow any procedures, just pounce directly.

As soon as it got close, the red dwarf moved towards Chen Yuan due to the effect of gravity.

"Swallow."
