Wandering planet that will travel

Qiao Lv looked at the pitch-black surface of the sphere. If it wasn't dotted with starlight, people might think it was a black hole that swallowed everything.

Ding Yi smiled and shook her head: "No, no, black holes are not holes. You should know that black holes are extremely massive celestial bodies. If such things appear in the solar system, none of the nine planets will be able to escape."

"But do you call this a hole?"

Qiao Li looked at the dark matter wormhole again. No matter from which angle he looked at it, it was a sphere, which was quite different from any wormhole he had seen before.

"Well, strictly speaking, it's a spherical hole, and essentially a projection of a high-dimensional space onto a low-dimensional space, with hardly any mass."

This can explain why it has such a large volume, but it does not produce a huge gravitational force.

But all of this still made Qiao Lv feel unbelievable, as if breaking the laws of this world.

"It's not that it's impossible to jump in this universe, why does this wormhole work again?"

Ding Yi smiled and said: "Because what we do is different! I said before that I can't do the warp because there is no hyperspace in this universe. In essence, we use the high-dimensional space, that is, the distortion of the hyperspace. Bending, but now that hyperspace doesn’t exist, of course there’s no way to jump through space.”

"But what we are doing now is to use dark matter to reconstruct a high-dimensional space, and then use this high-dimensional space to help us reach other corners of the universe."

"For example, hyperspace is like a highway in the universe. It used to be used for fast movement. When we first came here, we found that the highways in this world were all destroyed. Of course, there is no way to travel through space. gone."

"But now, we have learned to rebuild a highway. That's right, it's not just using it, but it can be built! Of course, it's not very long, it's only 4.2 light-years, which is extremely small for this universe, but It is a great progress for our humanity!"

4.2 light-years are not considered very long, and Qiao Li has a new understanding of these astronomical units.

However, according to Ding Yi, this may indeed be the first step for human beings to enter a high-dimensional civilization. After all, it is undoubtedly a qualitative leap from being able to use it to being able to build it.

With this dark matter wormhole, the wandering earth no longer needs to take a long interstellar journey, and now it may not even take a month to reach the Trisolaran galaxy. Such progress is simply unbelievable.

"We're coming!"

During the conversation between the two, the wandering earth was already close to the dark matter wormhole, and the surface of the wormhole, as huge as Jupiter, shrouded the sky above the wandering earth.

At this moment, the wandering earth seemed to fall into another universe, just like falling into Jupiter, a gas giant, and began to immerse into the surface of the wormhole.

Fortunately, the dark matter wormhole itself has almost no mass, so there will be no problem of being torn apart by gravity beyond the Roche limit.

In the next second, the wandering earth entered a space that was constantly distorted and deformed, as if the entire universe was bent into a channel, and the stars that were originally too far away to be estimated now seemed to be within reach.

Ding Yi said excitedly: "We are ready to say goodbye to the solar system, and there are centaurs here we come!"

Centaurus, the original end of the wandering earth, where it was expected to take 2500 years to reach, is now almost instantaneous.

Of course, this is not the centaur constellation that the wandering earth originally wanted to reach, but the Trisolaran civilization where the Trisolaran civilization is located, the Trisolaran galaxy composed of three stars!

Chapter 681 Reaching the Three-Body Galaxy

After entering the wormhole, the wandering earth was submerged in an ocean of dark matter, and the universe seemed to become a flowing liquid, surging and churning all the time.

Countless stars turned into sparkling waves on this ocean, and the original distance of several light years was reduced to between sizes.

This place is like a miniature universe, or in other words, this is the phenomenon of space folding.

The wandering earth is like a flat boat, driving in this ocean of dark matter, traveling a distance measured in light years in an instant, quite a feeling of shrinking into an inch in ancient mythology.

When Qiao Lu proposed this idea, Ding Yi couldn't help laughing and said:

"Shrink the ground into an inch? Hahaha, it really smells like this."

He took out a piece of paper, drew two dots on it, and began to explain:

"If this is the solar system, and this is the centaur constellation of the Trisolaran civilization, generally if we want to go there, we can only have the shortest straight line between two points, and this distance is 4.2 light years."

Ding Yi connected the two points with a straight line, and marked 4.2 light-years on it, then this is to reach the constellation Centaurus in a conventional way, and it will not be too short no matter what.

"Now we fold the space and make a hole between two points."

He skillfully folded the paper in half so that the two points almost coincided, so that the two points were no longer the shortest straight line on the paper, and became infinitely close in three dimensions.

Switching to a three-dimensional space, then this is shrinking the earth to an inch. The original 4.2 light-year distance has been reduced to an unbelievable level, which is the principle of this dark matter wormhole.

At this time, Ding Yi used a pen to poke a hole in it again, and then spread the paper again. As a result, a hole was poked out near the two points at the same time.

Pointing to the two holes, he said: "This is the dark matter wormhole we created. It is a circle in two dimensions, but it is in the three-dimensional world..."

"Sphere, I understand."

Of course, this is just the most basic principle, just like 1+1=2 in mathematics.

You never know how complicated something that seems so simple will turn into later, and of course Qiao Li doesn't expect to be able to understand it.

In this way, the journey of the wandering earth was greatly shortened, and the end of the trip was reached after traveling in the wormhole for less than half a month.

The wandering earth rushed out of the ocean of dark matter, emerged from the other side of the wormhole, and came to this originally distant Centaurus galaxy.

From the moment he entered the Trisolaran galaxy, he could feel a scorching atmosphere, and the temperature suddenly rose by several degrees, as if he had returned to the ancient times when there were ten suns in the legend.

This place is completely different from the Centaurus known to mankind, and it is also different from the Centaurus A galaxy in the Avatar world. It is a completely unknown galaxy.

In reality, Centaurus is composed of a pair of binary stars and Proxima Centauri. The law of motion is simple and stable, so it was selected as the destination of the Wandering Earth Project.

However, what is presented to everyone now is a chaotic three-body galaxy, and the three stars appear out of the routine as if possessed by an evil spirit.

In other words, on the earth, the sun sometimes rises from the east and sometimes from the west. Sometimes there are two suns in the sky, and sometimes there is only one sun.

All these mysterious three-body movements constitute the hellish Trisolaran galaxy. After several long cold nights, there may suddenly be a hot day, or just the opposite.

But these are nothing, when the three suns appear under the same sky at the same time, there will be a high temperature that will sweep everything, burn the earth to a red iron plate, magma will flow horizontally, and the fire will rage to the sky, which is a proper purgatory on earth.

The Trisolaran civilization was born in such an environment, and has experienced more than two hundred cycles of destruction and rebirth.

This is why they must occupy the solar system. Compared with the Trisolaran galaxy, which has three stars moving alternately, the solar system has only one stable star, and the alternation of cold and heat is quite regular, and there will be no horrible doomsday in the sky for three days.

In the Trisolaran system, the wandering Earth quickly found the lonely planet.There are eight planets in the solar system, but there is only one in the Trisolaran galaxy, which is weak and helpless among the three stars, and is in constant fear of being swallowed by the stars.

The Trisolaran planet also has a satellite, but unlike the earth and the moon, this satellite is forcibly torn from the planet.

Due to the irregular motion of the three stars, the trisolaran planet will occasionally approach the Roche limit. The mass of Jupiter is 318 times that of the earth, and the tidal force generated is enough to tear the earth apart, let alone a star with a mass hundreds of thousands of times that of a planet !

This satellite is a piece of the Trisolaran planet that was torn out when it passed by the star, and the two irregularly shaped parts became spherical again after a long period of time under their own gravity.

This is the biggest warning to the Trisolaran civilization. Their civilization is always on the verge of destruction. One day in the future, the entire planet will be torn apart by the gravity of the stars.

The Wandering Earth slowly approached this precarious planet, and unexpectedly did not find too many orbital defenses, and there was no space fleet stationed there.

But this is a matter of course. For this planet that will be abandoned sooner or later, the Trisolaran civilization cannot waste resources on defense. No amount of orbital defense platforms can alleviate the threat of the three stars.

As for the absence of any space fleet, it was again Qiao Lv's fault.
