Start with a planet hitting the earth

Chen Yuan swallowed five medium-mass stars in a row.

The volume of the singularity remains unchanged, but its mass has increased to 96 times the mass of the sun, and the diameter of the event boundary has also become slightly larger.

But...even if it gets bigger, it's still very small.

At a singularity close to one hundred solar masses, the diameter of the event boundary is only about three hundred kilometers.

What is the concept of three hundred kilometers? You must know that the diameter of the sun is more than 1.3 million kilometers.

And now Chen Yuan's event boundary is only three hundred kilometers in diameter.

If the event boundary is also regarded as the volume of Chen Yuan, then the volume of Chen Yuan is still very small.

"After all, the event boundary is different from the volume of a star. It cannot be calculated as a volume." Chen Yuan thought: "You know, within this event boundary, there is a gravitational force that even light cannot escape."

"It's just..., well, this is too small." Chen Yuan had a headache.

"If you include accretion disks... that won't work either. Accretion disks don't always exist."

The formation of a black hole's accretion disk requires two conditions.

The first is that the singularity is rotating. If the singularity does not rotate, then the matter will be directly swallowed by the black hole, so that an accretion disk will not be formed.

The second condition is that the black hole needs to absorb a large amount of matter, and the matter rotates around the black hole, so that a bright accretion disk can be formed.

In other words, as long as Chen Yuan prevents himself from rotating or absorbing matter, the accretion disk will disappear.

All that was left was a pitch black hole.

Therefore, it is naturally impossible to calculate accretion into volume.

"You are a black hole. How can a black hole compare in size to a star?" Ya said with great interest: "For you, no matter how big the stars are, as long as you get close, they will only become your food. The larger they are, the greater their mass. For you, their only function is to be swallowed up by you.”

"The power of black holes does not depend on their size, but on their gravity. You can compare gravity with them." Yaxiao said, "This way you have a great chance of winning."

Chen Yuan said: "I know, it's just that I was so big before and now I'm so small. I'm just a little depressed."

Ya smiled: "What's the hurry? For you now, as long as you don't provoke other black holes with higher mass than you, you are invincible. As long as you are given time, then I believe that nothing in the entire universe can compare with you. powerful."

"Yeah, too."

Chen Yuan saw a huge star in front of his eyes.

Chen Yuan's heart moved when he saw the star in front of him.

"Good guy, this thing is really big."

In front of us is a huge red supergiant star.

Red supergiant star.

A massive star that is on the verge of death.

They evolve from massive stars. Such giant stars generally have very large diameters.

The diameter of the red supergiant star in front of Chen Yuan is fully seven hundred times the size of the sun.

This is the first time Chen Yuan has seen such a large star.

But its mass is only 20 solar masses.

"Such a small mass can produce such a large volume. Helium fusion is really amazing."

"Swallowing such a red supergiant star seems to be a pleasure." Chen Yuan thought and slowly leaned over.

From the outside, a black hole can be seen, close to the red supergiant star.

As it approached, the material on the red supergiant was pulled into Chen Yuan's body by Chen Yuan's gravity.

Because Chen Yuan, as a singularity, is rotating, an accretion disk suddenly forms around Chen Yuan.

The closer it gets, the brighter the accretion disk becomes.

The mass of the red supergiant quickly flew towards Chen Yuan and became Chen Yuan's mass.

When Chen Yuan stepped into the red supergiant, he could feel that he was completely enveloped by the mass of the supergiant planet, and that mass was quickly becoming Chen Yuan's mass.

This feeling is like a small and extremely hot sphere being thrown into a big ice ball. Because the ball is too hot, the big ice ball is vaporized little by little before it can touch the ball.

Of course, it is still a little different than that. After all, the material of the giant red star itself is vaporized.

They were directly crushed into atoms by Chen Yuan's gravity, entered the black hole, and then were crushed into things smaller than atoms and swallowed by Chen Yuan's mass.

All the mass of the red supergiant star was completely swallowed up by Chen Yuan.

Chen Yuan's quality has experienced another huge increase.

"This feeling of swallowing a large celestial body with a small volume is quite pleasant." Chen Yuan enjoyed it very much.

"Next one." Chen Yuan flew leisurely in another direction.

"Look at how proud you are." Ya's voice was filled with laughter.

Chen Yuan smiled: "Risk your life and become a black hole. If it doesn't make me proud, then becoming a black hole would be meaningless."

"Well, that's true. By the way, I have to remind you that if you continue on your current path, at your speed, you will encounter a civilization in another twenty years. That civilization, you have seen it before It’s called earth civilization.”

Earth civilization?

"Come back again?"

He looked through his perception ability.

He saw a blue planet surrounded by a huge ring.

That blue planet is quite similar to the Earth. Of course, it is much smaller than the previous Earth. However, since people on the Earth all live in it, it is called a small Earth.

After so many years, the rings around the blue planet have increased.

Previously there were two rings, but now there are three.

The function of those rings, Chen Yuan knew from Ting Ya that they were used to repair the planetary environment and protect the earthlings from harm.

Next to the small earth, there are also artificial satellites orbiting one after another.

These artificial satellites are different from the previous artificial satellites.

The previous artificial satellites were only used to observe the surface of the earth.

And the artificial satellites next to the small earth are half the size of the moon.

Those artificial satellites are made of rock and metal.

And like the small earth, these artificial satellites are also surrounded by rings, and there are more of them. Each artificial satellite that is half the size of the moon is surrounded by five rings.

"It looks like those artificial satellites are intended to be used for living."

Chen Yuan muttered, and through his perception ability, he really saw people walking on the artificial satellite.

Inside the artificial satellite, there are also cities built one after another.

The people in the city are going about their daily lives just like on the small earth.

Some of them had smiles on their faces, while others had sad expressions.

Obviously, they have adapted to living in artificial satellites.

They have settled in artificial satellites.

"Are there a total of six artificial satellites that can be inhabited by humans? The materials of these artificial satellites should all come from other rocky planets, otherwise the small earth alone would definitely not be able to provide so much mass. It's amazing, I didn't expect that the current earth civilization can already make artificial satellites that can be inhabited by humans."

"It has changed a lot."

"If I hadn't been reincarnated as an asteroid at that time, could I have become one of them?"

"...Forget it, either I will die in the nuclear winter, or I will have died of old age."
