Chapter 365: Primordial Gravitational Waves

While thinking, Mr. Yunguang Civilization Chairman finally made a decision.

After the absolute safety time of human civilization expires, if there is no other change in the situation, then we can just stay put and let Hongyang and other four civilizations go first.

At this moment, in the virtual conference room of the four heads of state of the four civilizations, the faces of the four new heads of state were full of joy.

Their think tanks combined with the recent actions of human civilization and also analyzed similar conclusions.

This is undoubtedly good news for the four civilizations.

We can't beat humans, and we can't beat you five ordinary third-level civilizations? What level of civilization are you worthy of fighting us?

In this way, we have a total of 600,000 first-line warships and hundreds of millions of elite soldiers. Isn't it possible that we don't have to die in vain?

Even for an entire civilization, a single civilization with hundreds of thousands of warships and hundreds of millions of elite soldiers is a huge fortune. Once lost, the entire civilization will be hurt.

Not to mention the problem of how to explain it to the inside if defeated.

We originally relied on the support of the Yunguang civilization to rise to power, and our internal support was not high. Once we have this complete failure, we don't know how rampant the internal opposition will be.

Now, as long as we defeat those five civilizations, we can avoid failure and win honor internally...

For a time, the spirits of the four heads of civilization were all lifted.

"Humanity is craving for a miracle. Unfortunately, this universe is dark and cold, and there are not so many miracles."

"At present, humans are determined to save silver coins as soon as possible, which also means that they are simply unable to participate in subsequent wars. Our chances have greatly increased."

"People facing a dead end will always burst into the last madness, always try their best to save themselves, and even make some ridiculous things, but they will regard these things as a life-saving straw."

...

The 103rd year of absolute safety time.

Meeting room of the ruling committee.

"At present, the strategic deception plan is going smoothly."

Comprehensively analyzing various information and combining feedback from major civilizations, Han Yang came to this conclusion.

"With our self-weakening, the four major civilizations such as Hongyang have regained their confidence in fighting against our Pan-Sun Alliance, and the Yunguang civilization has also had the hope of avoiding its own fate and the determination to hand over the task of annihilating us to the four major civilizations."

The ultimate goal of the strategic deception plan is to delay the time for the Yunguang civilization to personally take action by 150-200 years, so as to buy another precious time for our own development.

To achieve this, we must let the four major civilizations take action and start a war with us, and delay time through war.

The key to starting a war lies in the hope of winning.

That is, we must let the four major civilizations such as Hongyang have the hope of winning, so that they will seriously start a war with us instead of directly sending themselves to death.

However, our strength is already recognized as strong in the third-level civilization. How can we let the four major civilizations such as Hongyang have the hope of winning?

That is the Endeavor Plan at this moment.

Everyone has seen with their own eyes that our human civilization has made a desperate effort to advance to the fourth-level civilization, and has pulled away most of its military forces to earn silver coins. It is completely unable to defend itself, and can only introduce foreign forces through the Pan-Sun Alliance. Moreover, the strength of foreign forces is not that strong. As long as they win, they can destroy us humans--

Are you still not tempted? Aren't you excited? Then what are you waiting for? Don't come and die directly, come and fight us seriously.

Interstellar wars, especially interstellar wars involving multiple civilizations, are bound to be protracted. As long as you fight seriously, there is no need to deliberately and specifically delay time.

Even if you want to speed up, you can't speed up.

In this way, won't time be gained?

The only drawback of this plan is...

A ruling committee member sighed: "Our civilization will go all out to carry out the high-risk combat missions issued by the Silver Alliance and other civilizations, and there will be a large number of casualties.

The five major civilizations of Yuanshan, Motan, Fix, Chitie, and Ziyun will fight against the four major civilizations of Hongyang, Wuta, Black Water, and Snow Region, and there will also be a large number of casualties.

The three civilizations of Yuanshan, Motan, and Fix are better. We support them, and they deserve to make sacrifices.

The most important thing is the casualties of ourselves and Chitie and Ziyun civilizations..."

Even our own casualties are nothing.

After all, this is to fight for the future of our own civilization. The duty of a soldier is to defend his homeland. Even if he sacrifices, as long as it is valuable and meaningful, it is also his due.

It is a little bit sorry to let Chitie and Ziyun civilizations suffer a large number of casualties.

Liu Yuan said solemnly: "When the future situation is determined, they will understand the value of sacrificing for us humans at this moment. Their soldiers will not sacrifice in vain."

"Yes."

...

At this moment, behind the simultaneous implementation of the Strategic Deception Plan and the Endeavor Plan, the entire human civilization, as well as Han Yang himself, are fully engaged in learning the scientific and technological data of the Yunguang civilization.

This batch of scientific and technological data is too large. Even if there are billions of high-quality scientific research experts in human civilization, plus Han Yang himself has a powerful computing power that is dozens of times more than before after several large-scale upgrades, it is not easy to digest all of this batch of scientific and technological data.

But, no matter how difficult it is, we have to do it.

This precious time, which allows us to go all out to learn knowledge, was won by the sacrifice of hundreds of millions of elite soldiers in the previous galaxy cleaning mission.

That is hundreds of millions of living people with their own ideals and lives, and hundreds of millions of families.

Such a huge price has won the current opportunity. Anyone who dares to waste it is a crime against the entire civilization.

Regardless of whether they will be condemned in their hearts, Han Yang will never allow such a thing to happen.

In this situation, the scientific and educational circles of human civilization also burst out with almost the same fighting enthusiasm as the fleet soldiers before.

The knowledge difficulties are the enemy, the laboratories and research institutes are the battlefields, the weapons are their own hands and brains, and the efficient organization and communication system involving the entire civilization level.

This is a battlefield without gunpowder smoke, a battlefield without shouting and killing, and without the wreckage of warships and the flash of explosions. But the fierceness, cruelty and difficulty of this war are no less than the real fighting on the battlefield.

What Han Yang said at the beginning was that the entire civilization must do its best, no matter which field or which industry, to have the hope of winning this war and continuing civilization. This is not an empty talk.

Under this situation, at this moment, that is, the 143rd year of absolute safety time, the first phase of the battle is declared over.

All the scientific and technological data that the third-level civilization can master from the Yunguang civilization before the theory of everything has been digested and absorbed by the human scientific community and Han Yang himself.

This is a phased result. At the same time, Han Yang also knows that the human scientific community may not be able to provide him with much help in the future.

Because next, humans will really charge towards the theory of everything. And this is a solid basic scientific theoretical research, which requires extremely high basic scientific research and pioneering capabilities.

In the past hundreds of years, after continuous purchase of new scientific data, the basic scientific research and pioneering capabilities of human civilization itself have been almost destroyed, and it is impossible to repair them in a short time.

At this moment, the only one who is capable of charging into a new field is Han Yang himself.

In this process, the human scientific community can only provide some auxiliary help at most. For example, if Han Yang has developed any new theories and achieved any new results, he can teach these things to human scientists again, so that they can carry out some auxiliary work in the corners or application transformation based on these foundations.

The real problem still needs to be solved by oneself.

Han Yang knows that the road ahead will be difficult, but there is no retreat for humans and no retreat for himself.

All he can do now is to face the challenge head-on.

After launching a charge towards the theory of everything, the first problem Han Yang faced was the problem of quantization of gravitons.

The so-called quantization of gravitons, in simple terms, is to use the framework of quantum mechanics to describe gravitons.

The key to this problem lies in confirming whether gravitons exist.

Quantum mechanics believes that force is transmitted through particles. For example, strong interaction force is transmitted through gluons, weak interaction force is transmitted through W and Z bosons, and electromagnetic force is transmitted through photons.

Just like two magnets attract each other, this is a manifestation of electromagnetic force, but why do two magnets attract each other?

The answer from quantum mechanics is that the two magnets exchange photons with each other, so attraction is generated.

Since three of the four fundamental forces are transmitted through particles, is gravity also transmitted through gravitons?

If so, what properties does the graviton have?

Based on existing theories, scientists can predict that the graviton is a boson with spin 2, zero mass, and no charge.

But the current problem is that humans have not yet detected the existence of gravitons.

How can we quantize gravitons if we cannot even determine whether gravitons exist?

General relativity believes that gravity is the curvature of space-time. That is, gravity is actually just a geometric phenomenon - it is just a phenomenon, so there is no graviton.

Quantum theory believes that gravity is also transmitted through particles, that is, gravitons, so there are gravitons.

Therefore, confirming whether gravitons exist has become the first threshold to launch a charge towards the theory of everything.

——Of course, through the existence of level 4, 5, and 6 civilizations in the Silver Alliance, as well as the iconic technologies mastered by these civilizations, Han Yang can know that gravitons do exist, but this is actually meaningless.

Just like a difficult math problem, if a person can't do it, then directly giving him the answer to the math problem, and achieving the effect that he has solved the math problem on the surface, is actually meaningless.

He does not have the knowledge required to solve this math problem. Even if he knows the answer, he can't use this knowledge to solve other problems.

The result is not important, what is important is the process.

Just like now, Han Yang can know that gravitons do exist, but this is not important. What is important is the process of verifying the existence of gravitons step by step.

Only by mastering this process can we use this knowledge to transform it into practical results.

The simplest and most intuitive way to confirm whether gravitons exist is to observe them. If they can be observed, then of course they can be confirmed to exist.

However, according to theoretical calculations, gravitons have very special properties, and it is very difficult to observe gravitons, so difficult that it is unimaginable.

As we all know, another particle called neutrinos, because of its extremely strong penetrating power, even every human on Earth, which is about the size of a thumbnail, will penetrate about tens of billions of neutrinos per second, and all neutrinos that penetrate the human body will hardly react with any particles that make up the human body.

Because of this, it is also very difficult to observe neutrinos.

However, no matter how difficult it is to observe neutrinos, humans who were still in the first-level civilization stage at the time built a huge neutrino telescope and successfully observed neutrinos.

People have poured about 50,000 tons of ultrapure water, or 50,000 cubic meters of ultrapure water, into a huge container. In this way, when a large number of neutrinos penetrate these ultrapure waters, even if the probability of hitting water particles is too low, because there is too much water, there will always be a few neutrinos that are unlucky enough to hit them, thereby causing secondary radiation and being observed.

It can be seen that a neutrino telescope with a volume of tens of thousands of cubic meters can achieve the purpose of observing neutrinos, which have super penetrating power.

But as an analogy, based on the stronger penetrating power of gravitons, assuming that the earth is hollow and the entire interior of the earth is filled with ultrapure water, according to theoretical calculations, it will take an average of about one billion years to observe a graviton colliding with a water molecule, thereby triggering an electron transition event.

The volume of the earth is about 1.81*10^16 times the volume of the above-mentioned neutrino detector. Taking into account the time difference, it can be simply estimated that the penetrating power of gravitons is at least 27 times that of neutrinos, that is, 660 billion billion times.

Neutrinos have such strong penetrating power, and detecting neutrinos is already so difficult. So, how to capture gravitons, which are at least 660 trillion trillion times stronger than neutrinos?

This is almost an impossible task.

Directly detecting gravitons, let alone level 3 and level 4 civilizations, I am afraid even level 6 civilizations cannot do it.

But fortunately, Han Yang does not have to detect gravitons directly. He has a more clever way.

Primordial gravitational waves.

If the existence of primordial gravitational waves can be confirmed, then it can be confirmed that gravitons really exist, and the quantization of gravitons can be completed.
