Xu Zhenghua was still very weak at this moment. After all, he had just undergone a major operation. But with this operation, the feelings that he had been reluctant to leave for a long time, such as chest tightness and chest pain, had disappeared.

That is an external manifestation of the heart no longer healthy.

But now, he has become a "heartless person". Some mechanical creatures replace his original heart and begin to supply blood to his organs throughout his body. And mechanical creatures will not get sick.

As long as the parts can be replaced in time, it can work diligently until the end of the day.

Faced with Xu Zhenghua's request, Dr. Zhou Changqing smiled bitterly.

"Professor Xu, don't make things difficult for me. You have just finished the surgery and need more rest."

Xu Zhenghua said: "I have changed my heart, what else can I be afraid of? Isn't this thing going to have a heart attack or something, right?"

"Uh, theoretically not, but..."

"No, but. I'm in good shape now."

Zhou Changqing was sweating profusely and could only say, "I'll apply to my superiors."

Xu Zhenghua's words attracted everyone's attention.

Almost everyone believes that observing the "unobservable universe" is an impossible thing, and logically this matter is not true at all. But they also know that Xu Zhenghua will not lie.

He said that if there is a way, there must be a way.

And this matter is extremely important to the current human civilization.

However, Xu Zhenghua's physical condition had to be carefully considered. So, after the decision makers personally listened to the opinions of many medical experts, they made a decision.

Xu Zhenghua was required to strictly follow the doctor's instructions, and after three days of rest, he would conduct another physical condition assessment. If he did recover well, he could carry out limited work.

Faced with the advice of a decision maker himself, Xu Zhenghua had no choice but to calm down and spend three days in meditation. Three days later, Xu Zhenghua, who finally received permission from the medical team, finally got what he was thinking about.

Several pens, a stack of paper, and a computer that can directly connect to the Yinglong supercomputer.

He once again devoted himself to work.

He has been thinking about this question for a long time. Perhaps it is because of the special reactions of anesthetics and certain brain activities that have become the key to ushering in this inspiration and breaking the deadlock.

But it is just a key. This means a possibility, and whether this possibility can be fulfilled still needs further verification.

Three more days later, when Xu Zhenghua was allowed to walk freely - of course, the artificial heart had to be carried with him at all times, which made his chest and abdomen bulge high, and when he looked through his clothes, he felt like he had suddenly had a big belly - he confirmed his thoughts.

Theoretically, this is indeed feasible. I just don’t know if the human world has this ability in engineering.

First of all, it is still not possible to observe the "unobservable universe". To confirm the size and radius of the unobservable universe, you must use other methods. Xu Zhenghua used that inspiration and calculation to link the quantum entanglement effect with the radius of the unobservable universe.

He has confirmed that in the quantum entanglement effect, there is an upper limit for the speed at which two particles in the entangled state affect each other's state. But he cannot know what the upper limit is.

Is it ten thousand times the speed of light? one hundred million times? or one trillion times?

He doesn't know.

But he can confirm that this speed is directly related to the size of the unobservable universe. Simply put, there is a relationship between the two: if the quantum entanglement speed is infinite, then the size of the unobservable universe is infinite. If the quantum entanglement speed is ten thousand times the speed of light, then the number ten thousand is multiplied by a certain coefficient, and the final result is that the radius of the unobservable universe is a multiple of the observable universe radius.

However, the speed of quantum entanglement can be measured.

Of course, people do not have the ability to measure the accurate speed of quantum entanglement, just as people cannot measure the size of the unobservable universe. But people have the ability to determine its lower limit, that is, people can know that the speed of quantum entanglement must be above a certain speed.

The higher the observation accuracy of the equipment people build, the more likely it is to increase this lower limit. In this way, people can know how many times the unobservable radius of the universe is at least several times the observable radius.

If the observation accuracy is high enough, and under this observation accuracy, the quantum entanglement speed is at least a sufficiently large multiple of the speed of light, then people may come to the conclusion that although the size of the unobservable universe is still undeterminable, the unobservable universe is at least more than one trillion times the observable universe radius. In this way, people can say with great confidence that in the unified universe model, external designers are theoretically capable of designing human observable universes, so that multi-layer nested universe models can be discarded. Because the unified universe model is simpler, more perfect, and has higher credibility than it.

Of course, the conclusion drawn by the final experimental observation results is that if the speed of quantum entanglement is determined to be not fast enough, the unified universe model will be completely denied. If the unified universe model is denied, the multi-layer nested universe model will be proved to be correct again.

The reason is very simple. Since there is no theoretical possibility of designing and building a human observable universe in this universe, it can only be the previous universe.

From this perspective, this can also be considered an exclusion method. Excluding this universe, only the previous universe is left.

But no one can determine the specific results at this moment. Everything depends on the final experimental observation results.

Xu Zhenghua's ideas once again caused a sensation. Before this, no one had ever thought that the size of the unobservable universe could be determined in this indirect way. What's more important is that Xu Zhenghua actually came up with a complete set of logically rigorous mathematical and physical proofs to verify the close connection between the two, and passed the evaluations of many scientific researchers.

Then the next thing is the engineering level.

To improve the accuracy of this test, we need to work hard in two aspects at the same time. One is of course to improve the accuracy of the timer and the observation equipment as much as possible, and the other is to increase the distance between the two experimental sites as much as possible.

The experiment idea is very simple. Set two experimental sites A and B that remain relatively stationary and are far away enough to detect quantums in the entangled state while point A is observing the quantum in the entangled state and causing it to collapse, a laser light is emitted to point B. Point B simultaneously records the collapse time of the quantum in the entangled state observed by oneself and the time when the laser light emitted from point A is observed.

Because the laser moves at the speed of light, and the distance between the two sides is known and time is also known, through simple calculations, it can be calculated how many times the speed of quantum entanglement is at least as fast as the speed of light.

If you want to improve the accuracy again, then you can increase the distance between the two sides again.

At this moment, with human technology, the shortest time interval that can be measured is 2 at seconds. If the time less than 2 at seconds is not noticed by human devices at all. So people use the time length of 2 at seconds as the basis and multiply it by another number for ten trillion billion - if the radius of the unobservable universe is more than one thousand trillion times the observable universe radius, then the speed of quantum entanglement must be at least more than ten trillion times the speed of light - the result is 2,000 seconds, and the speed of light advances by 2,000 seconds, which can transmit a distance of about 600 million kilometers.

Therefore, the distance between point A and point B must be at least 600 million kilometers to meet the observation accuracy. In fact, in order to ensure accuracy, people finally determined this distance to be 800 million kilometers.

This distance is about slightly less than the distance between Jupiter and the Sun.

With humans' long-distance voyage capabilities at this moment, they are fully capable of sailing a distance of 800 million kilometers, even longer than this distance. However, after considering various factors, people finally determined the distance of 800 million kilometers.

After the intense and rapid preparations in the early stage, when Xu Zhenghua's aging heart, which was removed from his body, was finally repaired through the most advanced technology and then loaded into his chest, the space elevator and space end, which is also the largest space base for mankind, has been urgently modified from the Stardust ocean scientific research ship, carrying a large amount of scientific research equipment and various materials, as well as five astronauts, left the earth.

In order to save time, the Stardust Ocean Survey Ship did not adopt the conventional way of traveling back and forth between different planets many times, and used the gravitational force of different planets to accelerate itself. Instead, it directly broke free from the gravity of the earth and started the acceleration journey directly on its own fuel. After about two months, it arrived at the predetermined location.

It reduces its speed to not even enough to maintain the speed around the sun, just to remain relatively stationary with another spacecraft launched about 170,000 kilometers from the earth. This speed is unstable, and gravity will cause it to fall to the sun. It is just that the engine that is started at any time offsets this part of the gravitational influence, allowing it to stay here.

A laser beam emitted from point A and flew towards it. At the same time, particles in the quantum entangled state also collapsed due to the arrival of external observations. This time period was recorded by an atomic clock with an accuracy of 2 at a time.

After about 44 minutes, this laser beam controlled by the ultra-high accuracy steering instrument accurately traveled 800 million kilometers a long distance and reached the receiver of the Stardust Ocean Scientific Research Ship. At this moment, the atomic clock on the Stardust Ocean Scientific Research Ship also recorded the current time period with an accuracy of 2 at a time.

Subsequently, the data from this test were recorded and sent back to the direction of the earth by a high gain antenna.

The experiment was repeated dozens of times in total, and it took several days. After that, the Stardust Oceanographic Research Ship stopped its position and continued to advance, so it began to "fall" towards the inner solar system under the influence of the sun's gravity. After completing the posture adjustment, its engine was started again, so it truly embarked on the journey back to the solar system.
