I Spread the Cosmos By Live Broadcast of Food

What is further 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 a boundary? !

Of course the universe has boundaries!

Whether it is the 21st century or the interstellar 100,000 years, the universe we live in is a three-dimensional universe, and 666 comes from a high-dimensional universe.

As for Jiwei, Lan Siyu still doesn't know. She thought, probably four or five dimensions?

In addition to multidimensional universes, there are multiverses, and multiverses are also called parallel universes.

A parallel universe is a universe separated from a certain universe, which is the same as but different from the original universe. Two universes may have the same planet, the same species, the same history, but may also have different timelines.

Maybe you in this universe are old and dead now, maybe the species in this universe have long been extinct and culture has long since disappeared; but in the parallel universe, you are still young, species still exist, and culture is still being passed on.

The two universes never intersect.

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

Lan Siyu allowed himself to drift around, and by the way, his thoughts diverged, and he already thought of his happy life after getting rich.

Floating and floating, Lan Siyu, who didn't look at the road, felt as if he had bumped into something.

what is it then? At first glance, it is a wall. A translucent wall.

Although it was translucent, Lan Siyu couldn't see what was beyond the wall, only darkness was reflected in his eyes.

Lan Siyu's surroundings also became almost dark, and she reached out to touch this wall, which was soft and extremely resilient.

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

And this wall is impenetrable to creatures and matter in the entire universe. Probably, this can be understood as the boundary of the universe.

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

After drifting for an unknown amount of time, Lan Siyu 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 some celestial body? Or at the singularity of this universe?

Lan Siyu was thinking about these questions, and couldn't help but think of the origin of the universe, the "big bang cosmology".

The universe was formed by a dense and hot singularity that exploded and expanded 13.8 billion 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 the major planets, the major galaxies and other celestial systems is getting bigger and bigger.

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

So, where was the center of the Big Bang?

Thinking about it, Lan Siyu began to scratch her head subconsciously. Although she is now in the state of a simulated soul and has no real object, this does not stop her habit of scratching her head when she thinks about problems. After all, it is impossible for her to buckle her feet, because that would have a bad effect.

She is an internet celebrity lord with the baggage of an idol!

The center of the Big Bang? How does she know? The universe has not been explored to one billionth, who knows where the center of the big bang is? !

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

Lan Siyu really tried to recall what she didn't know about the universe. She should be glad that she is in the state of a soul now, otherwise a piece of her scalp would have been deducted from her.

"Think about it together now, think about it when you encounter difficulties."

After singing this line talking to herself, Lan Siyu said that she couldn't remember the following lyrics!

Suddenly, in a thought, she caught something! oh! She remembered!

Clues are not let go like a super detective? !

Well, she remembered.

One day, when she was watching the news with Panpan, a Federal report said that in the observable universe, the expansion images at different locations are the same.

In other words, any point is the center of the universe, and 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 the surroundings. This is 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-time, which is carried out in the state of nothingness. After the expansion explosion, time and space and all celestial substances in the universe are produced.

Starting from nothing, the current 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 centered everywhere, and the universe has no center." This view is naturally based on the universe formed by the explosion of the singularity, 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 universe center of this three-dimensional universe exists in the four-dimensional universe.

Lan Siyu thought about it and went around, his mind was probably full of mud now.

"It doesn't matter, fill in the four-dimensional universe and run away!"

She wants to go home and sleep, she's tired, old, and can't take it anymore.

Now she is even thinking of dropping out of school after finishing this year, and she doesn't want to come to the next year's field training.

With a thought, Lan Siyu returned to the original room. Lan Siyu turned on the terminal, started to connect to Yigao's dedicated local area network on this planet, and logged in with her student number to start answering questions.

[Question: Where is the center of the universe to be simulated by the universe simulation system? 】

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

Ah, more than 2,000 people have answered the question...

Lan Siyu thought about it and then filled it in.

[Lan Siyu: Four-dimensional universe. ] Click "OK".

[Submitted, will enter review within one minute. 】

Lan Siyu rubbed her hands nervously, watching the progress on the screen in front of her, watching the circle go round and round there.

It made her flustered.

[Verified, congratulations to Lan Siyu from the Special Enrollment College for completing the task in the field training in star calendar 100002! 】

Before Lan Siyu had time to be happy, the surrounding space changed instantly.

She's back in the water again!

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

Lan Siyu swam up quickly, although she didn't know where this was, but it was always right to swim up. She didn't want to meet those horrible and ugly monsters again.

Within half an hour, Lan Siyu got his head out of the water.

Looking around, Lan Siyu realized that he couldn't see the land at all...

O sea, you are all water!

Lan Siyu doesn't know where to swim now.

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

The round object began to grow larger, and after a few minutes it turned into a bowl-shaped levitator that could carry one person, and Lan Siyu climbed up it unsteadily.

As soon as he climbed up, he was paralyzed on all fours.

"I'm exhausted!"

Lan Siyu looked at the blue sky in a daze.

There is no scientific basis for the origin of the universe, so there is no scientific basis for the origin of the universe, so the author in the article selected a guess suitable for the setting of this article after reading various materials and books. Then, add your own fiction! Well, fiction!

You can express your own guesses, ideas, etc., but please don’t say that one is wrong and the other is right. After all, these theories have not been confirmed. Of course, there is no one who is absolutely right and who is absolutely wrong. Thank you!
