The Goethe's rescue pod has a hibernation function, which allows the crew to survive in space for as long as possible with minimal energy consumption.

After setting the direction of the hibernation chamber, Pang Xuelin entered hibernation.

Tomoko doesn't care, anyway, as long as there is sunlight and where neutrinos exist, she doesn't have to worry about running out of energy one day.

Time passed day by day, and when Pang Xuelin woke up again, another half a year had passed.

"Husband, we're here at Saturn!"

Pang Xuelin nodded, the escape pod did not have a gravity system, and he slowly floated to the porthole.

Millions of kilometers away, a massive gas giant is floating silently in the void.

The most striking thing is the beautiful rings of Saturn around the planet.

However, Pang Xuelin and Zhizi's destination is not here.

Rather, it is a bizarre wormhole entrance 10 million kilometers away from Saturn.

It was through this entrance that the spaceship of the shrimp man civilization came to Earth.

In the real world, wormholes are just a scientific hypothesis.

The concept of wormholes was first developed in the study of Schwarzschild solutions. When theoretical physicists analyzed the solution of the white hole, through an Albert Einstein thought experiment, they discovered that the universe itself could not be flat.

If a star forms a black hole, then space-time is perpendicular to the original space-time in the Schwarzschild radius, which is the event horizon.

In the uneven space-time of the universe, this structure means a black hole.

The part within the horizon will combine with another part of the universe and create a hole there.

This hole can be either a black hole or a white hole.

And this curved horizon is called Schwarzschild throat, and it is a specific kind of wormhole.

Ever since the discovery of wormholes in Schwarzschild solutions, physicists have become interested in the nature of wormholes.

In 1935, Albert Einstein and Nathan Rosen mathematically perfected the explanation of wormholes.

For this reason, the wormhole is also known as the "Einstein-Rosen Bridge".

In general, the wormhole in people's mouth is the abbreviation of space-time wormhole, which is considered to be a possible shortcut in the universe, through which objects can be transferred in time and space in an instant.

But in the real-world history of physics, Einstein himself did not believe that wormholes existed objectively.

Therefore, wormholes have been considered to be only mathematically possible for decades after they were proposed.

It was not until 1963 that New Zealand mathematician Roy Kerr proposed a new hypothesis that regained theoretical support for the existence of wormholes.

Like humans, stars go through the process of birth, aging, sickness and death.

Kerr believes that if stars can keep rotating as they approach death, they will form the "dynamic black holes" we see in movies.

When we launch an object along the axis of rotation as in the movie, if we can break through the gravitational field limit at the center of the black hole, we will enter the so-called mirror universe.

The "extradimensional" space in which the astronaut Cooper in the movie "Interstellar" is located in a black hole can actually be seen as an interpretation of the mirror universe.

Entering the mirror universe from the universe is itself a time travel.

The wormhole connects the black hole and the white hole, and is transported to the white hole through the wormhole between the black hole and the white hole, and is radiated out.

Wormholes can also manifest in the normal space-time of the universe, becoming a superspace-time that suddenly appears.

In the real world, there is still debate about whether wormholes exist and in what form.

But in the world of "District 9", Pang Xuelin has already seen the true body of the wormhole.

The void where the wormhole is located is empty.

However, after Pang Xuelin drove the escape pod around the wormhole, he could clearly feel that when the sun's rays passed through the wormhole, there was a significant deflection.

Eventually, Pang Xuelin used the observed light information and quantum computers to construct a spatial model of the wormhole—an entrance that presents a high-dimensional nature in space.

"Could it be that the wormhole is connected to a high-dimensional space?"

Pang Xuelin frowned.

Tomoko on the side shook his head and said, "It's hard to say, but there is a theoretical possibility." ”

Pang Xuelin said: "Zhizi, if you enter the wormhole, can you use another Zhizi to detect the physical parameters of the internal space of the wormhole?" ”

Tomoko shook her head and said, "I'm not sure. It's just that according to the records of the shrimp civilization, fifty years ago, when they first crossed this wormhole and came to the solar system, the size of the wormhole reached a hundred kilometers. But twenty years ago, when they came to Earth through this wormhole, the diameter of the wormhole was only twenty kilometers. And just now, we calculated that the entrance to the wormhole is less than two kilometers. At this rate, it is estimated that in a few years, the energy to maintain the wormhole will be completely consumed, and the wormhole that appears in the solar system will completely disappear. I'm worried that after we go in, this wormhole will become more unstable, and if something happens to the wormhole, we will most likely get lost in high-dimensional space-time. ”

Pang Xuelin smiled: "Whether we get lost or not, we have to try." And now that I have completed the system task, I can leave this world at any time, if there is danger, I will directly take you back to the system space, and choose to return to the real world when the time comes. ”

Tomoko thought for a moment, nodded and said, "In this case, there will be no problem." ”

Soon, at the request of Pang Xuelin, Zhizi controlled the small lifeboat and slowly headed towards the entrance of the wormhole.

When the bow of the lifeboat touched the entrance of the wormhole, Pang Xuelin faintly felt that the light around him seemed to fluctuate through the porthole, and a small stone was thrown on the calm water, sending out a circle of ripples.

Soon, Pang Xuelin felt as if his body had been electrified, and he felt numb, and then, everything around him became strange.

Inside the escape pod, the originally white light suddenly broke down into colorful colors.

The space around the bridge was ghosted, and everything in the escape pod gave him a huge sense of depth and inclusiveness.

In his eyes, the bridge he saw was not a bridge, but a superposition of countless bridges, and every wiring in the bridge, every chip, and every logic gate on the chip were vividly visible.

This texture is breathtaking, giving people the feeling of containing Sumeru and mustard seeds.

"Tomoko, are you there?"

"Husband, I'm here."

Tomoko's voice came, as if it was close in front of him, and as if it was far away in the sky.

As soon as Pang Xuelin turned around, he saw countless wise sons appear in front of him.

He could see Tomoko's beating heart, and he could see countless atom-sized red nanobots flowing in Tomoko's body, and he felt that every detail of Tomoko's body was infinitely magnified in front of him.
