Chapter 295

What's farther away? Is it the boundary of the universe?

Oh, what are you talking about, the boundaries of the universe? No kidding, how can the universe have boundaries?!

Of course the universe has boundaries!

Whether it is in the 21st century or 100000 years, the universe is a three-dimensional universe, and 666 comes from the high-dimensional universe.

As for the dimension, LAN Siyu is still unknown. She thought, about four or five dimensions?

In addition to the multidimensional universe, there are multiple universes, which are also called parallel universes.

Parallel universe is a universe separated from a universe, which is the same as but different from the original universe. The two universes may have the same planet, the same species and the same history, but they may also have different timelines.

Perhaps you of the universe are now old and dead, perhaps the species of the universe have long been extinct, and the culture has long disappeared; But in the parallel universe, you are still young, species still exist, and culture is still inherited and carried forward.

The two universes never intersect.

LAN Xiangyu thought that she in the parallel universe should be a super rich man with countless wealth and beautiful men. Well, it doesn't need to be the same.

LAN like Yu Bian let himself drift everywhere. By the way, he thought of his happy life after he became rich.

Floating, LAN Xiangyu felt as if he had hit something without looking at the road.

What is it? Look, it's a wall. A translucent wall.

Although it was translucent, LAN Xiangyu could not see what was outside the wall, and his eyes only reflected darkness.

LAN Xiyu's surroundings almost became dark. He reached out and touched the wall. It was soft and tenacious.

No matter how hard she tried, she couldn't pierce it.

This wall is impenetrable to the organisms and matter of the whole universe. Probably, this can be understood as the boundary of the universe.

If there is a boundary, there is naturally a center.

After drifting for a long time, LAN Xiangyu finally remembered the final task of this field training - where is the center of the universe.

Where is the center of the universe?

At some point? On a celestial body? Or at the singularity of the universe?

LAN Xiangyu was thinking about these problems. He couldn't help thinking of the origin of the universe, the "Big Bang cosmology".

The universe is formed by the explosion of a dense and hot singularity 138 years ago. During these 13.8 billion years, the universe is still expanding, expanding all the time. With the accelerated expansion of the universe, the distance between major stars, galaxies and other celestial systems is getting larger and larger.

Perhaps the center of the Big Bang is the center of the universe.

So, where is the center of the big bang?

LAN Xiangyu thought and began to pick her skull subconsciously. Although she now simulates the state of her soul and has no real object, this can't stop her from thinking and thinking. After all, she can't buckle her feet, because it won't affect her well.

She is a net red Lord with idol burden!

The center of the big bang? How does she know? The universe has not explored one billionth of a billion. Who knows where the center of the Big Bang is?!

No, is her current state the so-called "ghost"?!

LAN Xiangyu really tries to recall that she doesn't know much about the universe. She should be glad that she is in a state of soul, otherwise she will have to buckle a piece of her scalp.

"Now think about it together. When you encounter difficulties, think about it."

After singing this sentence to himself, LAN Xiangyu said he couldn't remember the following lyrics!

Suddenly, between thoughts, she caught something! Oh! She remembered!

Clues are like super detectives?!

Well, she remembered.

One day, when she was watching the news with pan pan, a federal report said that in the observable universe, the expansion images of different places are the same.

In other words, any point is the center of the universe. It can also be said that the universe has no center at all!

In daily life, the explosion of an object starts from a point, and the explosion spreads from the point to all around. That's not the case with the big bang.

Although it is called an explosion, it is not an explosion in the known sense.

The big bang of the universe is the expansion of space and time, which is carried out in the state of nothingness. After the expansion and explosion, time and space and all celestial substances in the universe are produced.

Starting from nothing and starting from scratch, the present universe has been formed after 13.8 billion years of continuous expansion.

Therefore, the universe can be a singularity everywhere, that is, the universe has no center.

"The universe is the center everywhere, and the universe has no center." this view is naturally based on the universe formed by the singularity explosion, the three-dimensional universe.

For the three-dimensional universe, everything starts from the explosion and expansion of the singularity, but for the four-dimensional universe, because it is a higher dimension, the singularity really exists in the four-dimensional space.

Then, the cosmic center of the three-dimensional universe exists in the four-dimensional universe.

LAN Xiangyu thought about it and went around. His brain was probably full of paste now.

"Whatever, fill in a four-dimensional universe and run away!"

She wants to go home to sleep. She is tired and old. She can't stand the toss.

Now she is even considering dropping out after reading this year. She doesn't want to come for field training next year.

With an idea, LAN Siyu returned to his original room. LAN Siyu opened the terminal and began to connect to Yigao's special local area network on the planet, logged in to his student number and began to answer questions.

[question: where is the center of the universe simulated by the universe simulation system?]

The following line of small words - 2999 people have answered the question.

Ah, more than 2000 people have answered the questions

LAN Xiangyu thought again and again, but he filled it in.

[LAN Xiangyu: four dimensional universe.] Click "OK".

[submitted, to be reviewed within one minute.]

LAN Yueyu rubbed his hands nervously, looked at the process on the screen in front of him, and watched the circle turn around and around.

She was flustered.

[reviewed, congratulations to LAN Xiyu, a special enrollment college, for completing the task in the field training in the year 100002 of the ephemeris!]

Before LAN Siyu could be happy, the surrounding space changed instantly.

She's back in the water!

Looking around, there was no one except some aquatic plants and aquatic animals.

LAN Xiangyu quickly went upstream. Although he didn't know where it was, it was always right to swim up. She doesn't want to meet those terrible and ugly monsters.

In less than half an hour, LAN Yueyu came out of the water.

Looking around, LAN Xiangyu found that he couldn't see the land at all

Sea, you are all water!

LAN Xiangyu doesn't know which way to swim now.

Take out a round object from the terminal, press the button above and throw it on the water.

The round object began to grow. A few minutes later, it became a bowl shaped suspension that could carry one person. LAN Xiyu climbed up unsteadily.

As soon as I climbed up, I collapsed on my feet.

"I'm so tired!"

LAN Yueyu looked at the blue sky in a daze.
