All the false prophecies I made have come true?

Chapter 282 The place I want to go
"A computer capable of calculating the entire universe..."

"Can it really exist?"

Hearing this question, Pan Lishan was also taken aback.

It seemed that he suddenly returned to the night when he was at the Xiaoshan base.

He still remembered the conversation at that time, and at the same time, he also remembered that he once gave Lu Yun a completely negative answer.

At that time, I said, "If we can have an existence that includes all information elements, it is no different from evolving the entire universe, and what we need to consume is the energy of the entire universe."

That is Laplace's demon.

It's just that Pan Lishan already knew that this inference was incorrect.

After all, he is studying quantum physics. Whether it is from the amount of information or the state of the quantum itself, or even the energy consumed by this "Laplace demon", it can only show that it has been falsified.

Yet the universe is infinite, and even at this time they have learned about the existence of higher dimensions.

This in itself shows that the universe is not unique.

Whether it is a multiverse or a high-dimensional universe, they all confirm their existence, and they even do not interfere with each other.

In this case, does Laplace's demon really exist, and is there really a formula for determining the quantum state...

It's hard to say.

After pondering for a while, Pan Lishan finally spoke:

"Instead of asking if this machine exists..."

"Before that, let's explain the nature of time."

He didn't address the issue directly.

Instead, the topic was changed.

Lu Yun is undoubtedly very interested in this topic.

He nodded, listened to Professor Pan's small class, and started the class again.

"Here, we must first introduce a concept of entropy."

"entropy?"

Pan Lishan nodded: "First of all, the more chaotic the system, the higher the entropy."

"Conversely, the more stable the system, the lower the entropy."

"This is of great significance in astronomy, chemistry, physics... and even machine learning and artificial intelligence."

"This brings up the concept of information entropy again..."

"However, no matter what... Even now that our science has incorporated a large part of cultivation, this has not changed at all."

"It's because of the asymmetry in entropy."

"That brings us to other sciences."

"Including physics, including quantum mechanics, and the formulas mentioned in the theory of relativity, all of which show time symmetry."

"That is to say, whether time is flowing forward or backward, these formulas exist and can work."

Lu Yun frowned upon hearing this.

Indeed, even if you go back in time, these formulas can play their own role.

After all, time is used in physical calculations as lengths, not vectors.

This is something I have never considered before.

Research in physics and mathematics is actually discussing the truth of the universe.

So if these physical quantities have nothing to do with how time flows, it may also explain that the way time flows in the current direction may not be unique?

Thinking of this, Lu Yun also asked:
"Does this mean that time has been turned back?"

When Pan Lishan heard Lu Yun's sudden question, he was taken aback for a while, then smiled:
"Perhaps there is such a possibility."

"But that's not the point."

"The emphasis is on 'entropy.'"

Pan Lishan continued:

"The reason why I say time symmetry is because we can only observe the flow of time in the positive direction."

"And in this time that is flowing forward, the asymmetry of entropy explains the problem."

This time, they seem to have stepped into the topic.

"As I said before, the more chaotic a system is, the higher its entropy value."

"The more stable a system is, the lower its entropy."

"In the universe we observe now, as long as it is a natural evolution, it is developing in the direction of entropy increase with the passage of time."

Lu Yun raised his eyebrows: "Is it developing toward disorder?"

Pan Lishan nodded: "That's right."

"This is the law of increasing entropy."

Lu Yun thought for a while, and then said, "But why does time only flow forward?"

"Since those physical formulas are also valid in the time that flows backwards..."

"Then it is also possible to have reverse time?"

Pan Lishan said: "It's not so much that it can only flow in the forward direction...it's better to say that we can only observe the time that flows in the forward direction."

"As for why it is flowing in the positive direction..."

"This may be related to the distinction between positive matter and dark matter."

"According to the Big Bang theory, at the beginning of the universe, there should have been an equal amount of positive and negative matter."

"But of course ... we haven't observed any dark matter."

Pan Lishan said with a smile:

"After all, we are in the physical world, and time flows backwards."

"In the world of dark matter, time undoubtedly flows backwards. Maybe the other party is also existing in our world, but we can't detect the pros and cons of the other party."

Hearing this, Lu Yun only felt his heart twitch suddenly.

dark matter?
Time flowing in reverse?
Can't feel the pros and cons of each other?

Suddenly, that incomparably magnificent picture flashed in Lu Yun's mind.

It was an incomparably vast continent with almost no boundaries, where nature and science were perfectly combined, where... it seemed like a real paradise.

That is the home planet of the Interstellar Convention.

Is there time flowing in reverse?
"Dark matter..."

The reason why Lu Yun raised the question of "predicting all machines in the future of the universe" is that he wanted to know how the interstellar convention had captured its own existence at least tens of thousands of years ago.

He originally wanted to use this entry point to find the original place of the interstellar convention in terms of time, and perhaps complete the destruction, so that this universe no longer has the existence of the interstellar convention.

However, at this time, what Pan Lishan said seemed to be getting closer to reality.

When Lu Yun was thinking this way, he suddenly said:
"In other words, instead of discussing whether the future can be confirmed, it is better to discuss whether the other party's time is flowing in a positive direction?"

Pan Lishan shook his head:
"Whether there is a machine that calculates everything about events I don't know."

"But in fact, the end of this universe can still be predicted."

"Since the end can be predicted, it is natural to know the process through calculation."

"I also said before that the universe with positive flow of time is always in the stage of entropy increase."

"Countless energies in various forms are changing in the direction of heat generation."

"Transitioning to a state of disorder."

"And the end of the entire universe... will be after the entropy increases to the extreme..."

"Heat death."

Lu Yun didn't study these things. Although Pan Lishan tried his best to explain it in a simple and simple way, Lu Yun was still a little confused in understanding.

But this did not delay his ability to understand the essence of these things.

If the interstellar convention is the existence of the dark matter world, then many things can be explained.

For example, why they want to destroy the earth, for example, how what they did was observed by them, for example, why their target is themselves, all have answers.

If their starting point is the end of the universe, then their past is their future.

And within the technology of the other world, there may be a way to predict the future.

For example, even if a "machine that predicts the future" does not exist, they can still learn about the future of the positive material world by observing the positive material world.

"This……"

Lu Yun felt a little headache.

At this time, Pan Lishan spoke again and said:
"Do you still remember how you asked me when you were at the Xiaoshan base?"

Lu Yun nodded: "I ask if the future is certain."

Pan Lishan also nodded and said, "At that time, I didn't know your methods."

"But at that time, I was undoubtedly confirming the certainty of the future."

"I used a machine that can calculate everything in the universe as an example, but in fact, that is just an example."

"And now, you should understand what I mean."

"Our past is each other's future."

"And the other party's future is our past."

"If it wasn't for your existence..."

"Old Lu."

"There is no doubt that the future cannot be changed."

"Everything that happens in the passing time, whether you want to change the future or not, is already doomed in the past of the future."

"But if you can go to the past by yourself, of course these are two different things."

Hearing these words, Lu Yun fell into deep thought.

"From what I've seen now..."

"It should be possible to confirm that the Interstellar Convention is a dark matter civilization."

"It is extremely normal for civilizations in the same positive universe to conquer each other, be vigilant, and destroy each other."

"Let alone another civilization in the opposite direction of the passage of time."

"only……"

"There is still something wrong with the Interstellar Convention."

New questions appeared in Lu Yun's mind again.

"God, a four-dimensional life like the Mother Earth..."

"What is the relationship between them and the Interstellar Convention?"

"There must always be a reason for doing things according to the instructions of the interstellar convention?"

"Don't they know about dark matter?"

"……wrong."

"Because the future cannot be changed?"

Lu Yun suddenly remembered what God had said to him.

The reason why God can change the future is because he has karma with himself.

In fact, he himself cannot interfere with the future.

And the actual meaning of destroying the earth is to prevent oneself from continuing to change the future?
If you change the future yourself, will the past of the Interstellar Convention change accordingly?

For me, is the interstellar pact getting weaker and weaker?

After all, judging from the reverse flow of time of the other party, when the time of the forward universe comes to heat, the universe of reverse flow time is actually just beginning?
The end point and the starting point are staggered, and then start a new cycle again?
too difficult.

Lu Yun rubbed his temples.

Plus the "self" that I found at the place where the interstellar convention was located before.

These questions are too mysterious, and these answers are completely unsolvable for a while.

However, Lu Yun was not discouraged by this.

After thinking for a while, he found the crux of the problem.

That is, how do I enter the anti-universe that flows backwards in time?

With this question in mind, Lu Yun asked again:
"Have we ever observed the phenomenon of turning back time?"

"If you want to touch the world of antimatter, is there... no chance at all?"

Pan Lishan nodded.

He said: "At least, the current human beings have no chance."

Hearing this, Lu Yun gritted his teeth.

Does that mean that the interstellar pact... is completely invincible?
If the other party can come to the positive time universe, but he cannot go to the reverse time universe, then everything he does can only be defensive.

So what do we do next?
However, at this moment, Pan Lishan seemed to suddenly think of something.

He suddenly narrowed his eyes and said:
"but……"

"I saw a report."

"..."

"Wait for me to look for it."

Hearing this, Lu Yun was taken aback for a moment, and was overjoyed.

It seems that there is no chance at all?
Pan Lishan's fingers tapped on the keyboard. Although human beings have entered the brain-computer era, Pan Lishan is still used to the primitive way of using the keyboard.

"found it!"

"April 2014, 8."

"Supernova explosion detected."

Pan Lishan pushed his glasses and explained carefully:
"To be precise, it was detected twice."

"The electromagnetic storm produced by the supernova explosion is so strong that it can theoretically touch the boundary of the universe."

"And the two wind waves detected at the same time... are not just two explosions in the simple sense."

"It's the wave from the explosion that, while traveling through the Earth in one direction, travels through the Earth again in the other direction."

"If these two waves are divided into A wave and B wave, then flipping B wave will completely overlap with A wave."

"Such a phenomenon..."

"I think it's good enough to call it a step back in time."

Hearing this, Lu Yun gave another wry smile in his heart.

Supernova explosion?
That kind of energy intensity, I definitely can't reach it.

Moreover, even if it can be done, how can I be sure that I can enter the reverse universe because of this?

The situation becomes more and more complicated.

However, Lu Yun is not helpless.

At this time, after accommodating so much blue matter, he can see the past and future within a certain period of time.

When I learned the approximate time of the supernova explosion, I might...

This method can be used to observe the future and past of supernovae?
Maybe you can get some insight?

Maybe we can use this to get a way to go to the world of dark matter?

There are too many mysteries at this time...

What he wants to do is not to dig into the dead end, not to cling to a problem.

It's about taking the first step as soon as possible.
