(Thank you for the reward from my friend Lizhigong, my friend is okay to see the monthly pass of Ran and his friend jk7927~~)

"Doctor Qin, you're just in time!"

In the workplace, Ye Lingshuang has always been business-like, calling Qin Ling Doctor Qin. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"Let me introduce to you, this is Major General Yang Weili, deputy director of the National Manned Space Office, and also the first person in China to go to space for the first time. ”

Yang Weili is about fifty, his eyes are sharp, and he is full of a neat style unique to a soldier, although he is just an ordinary person, Qin Ling still respects this kind of person who has made special contributions, stretched out his hand, and said solemnly: "Hello Director Yang." “

"Hello, are you Director Qin?" Yang Wei shook Qin Ling with his iron pincer-like hand!

Qin Ling responded with the same force, and after letting go, he nodded and said: "The director can't say it, my job is to be a doctor, and it is my duty to treat diseases and save talents, and I have an honorary position in 302, just to facilitate entry and exit." ”

"Easy to get in and out?" Yang Weili showed a hint of displeasure and asked: "I know you, you are the boss of a big company, a star, or a doctor, and you are also valued by the above, do you also have expertise in aerospace?"

Qin Ling smiled slightly: "I don't dare to be a professional, but I can answer questions for Director Yang, about the detection of starships in the universe, this question is very good, with conventional means, even if the equipment that receives radar echoes is advanced to synchronous processing signals, the power of radar waves is strong enough, when the starship flies at a speed of 10,000 kilometers per second, there is only a maximum reaction time of thirty seconds, which is obviously very dangerous."

So the detection of starships ......

In this way, let's talk about the problem of the universe first, scientists have long proved that the universe is smooth and uniform in all phases and scales, that is to say, in any corner of the universe, there are light waves and electromagnetic waves, perhaps in some places the distribution is dense and sparse, but there is no absolute vacuum.

Starship detection uses this principle, it does not emit radar waves, but receives light waves and electromagnetic waves in the universe, and after a series of complex processing, synchronously generates a three-dimensional, almost 100% simulation of the starry sky map.

What does this mean? That is, the longer the starship travels in the universe, the more detailed and large-scale the starry sky map will be, which should be easy to understand, just like a person observing the night sky, the longer the observation, the more information it receives, and the more stars it finds.

Of course, in order to prevent the enemy from artificially disturbing the light and electromagnetic waves, creating a false impression to the starship and bringing the danger of impact, the starship will also install a counter-speed response radar, which has a few seconds of warning time, which is enough to evade.

In short, this is a disruptive technology, a large part of the structural design of the starship is to cooperate with this technology, the institute has built a model, which is fully feasible after demonstration, and I will give Director Yang a detailed introduction when I see the model later. “

Yang Weili pondered for a long time before he said: "Maybe it's because I'm lonely and unheard, I hope this is not science fiction, then let me ask another question, what is the matter with space jumping? Wormholes have not yet been scientifically proven, and the feasibility of crossing wormholes is only at the level of science fiction, where do you get the confidence to actually want to travel through wormholes?"

Qin Ling smiled: "Quantum mechanics has long proved that people can curl space-time in other ways, so that it allows space-time travel, and find out that this requires a negative curvature of space-time, like a saddle surface.

Ordinary matter has a positive energy density, giving space-time a positive curvature, like a spherical surface, so in order to curl space-time to the extent that space-time travel is allowed, a substance with a negative energy density is needed.

Positive energy is easy to understand, but where does negative energy come from?

Energy is a bit like money, if a person has positive energy, it can be distributed in different ways, but according to the classical laws of physics at the beginning of the last century, energy is not allowed to be overdrawn, and in this way, any possibility of time travel is ruled out.

However, quantum mechanics goes beyond the classical laws, which are based on the principle of uncertainty and are more generous, allowing overdrafts from one or two accounts as long as the total energy is positive, in other words, quantum theory allows for negative energy density in some places, and only needs to be compensated for by the positive energy density from other places so that the total energy remains positive.

Crossing the wormhole takes advantage of this concept, through a strange energy source called spirit stones, which interacts with the starship's anti-gravity furnace to generate negative energy, distorting space-time into a saddle shape, so that it can travel through the nearest straight line between the two places.

According to our calculations, the distance of the Earth from α-Centauri is 32 trillion kilometers, and the distance through the wormhole will theoretically not exceed 10 million kilometers. “

Yang Weili looked at Qin Ling dumbfounded, and said for a while: "Negative energy exists in theory, but what is this negative energy, no one can say clearly, the most accepted concept in the scientific community is the energy carried by negative particles, and the collision of positive and negative particles will annihilate each other, and the energy will return to zero, that is to say, even if negative energy exists, it is extremely unstable, and it is impossible to be used in practice, I don't understand your 302 crazy idea very much." ”

Qin Ling flipped his palm, took out a substandard spirit stone, handed it over, and said: "According to the laws of the universe, negative energy cannot exist alone, but with it, due to the lightness of the spirit stone and the special nature of change, as long as the energy source provided by the spirit stone is not lacking, in theory, a negative energy channel can always be maintained, and the starship will also have a layer of energy cover to isolate it to avoid the collision of positive and negative substances and annihilation of each other."

Please rest assured that none of us here is crazy, every danger has been fully considered, and it is impossible to risk our own lives, and the chief is also far-sighted, giving full support and stability to our concept, and when the starship takes off, Director Yang can let us travel the vast starry sky together, and everything will be understood. “

Yang Weili took the spirit stone, this small translucent milky white stone, extremely hard, but almost no weight, can't help but secretly surprised, you know, the law of the universe is that the harder the substance, the greater the mass, the greater the weight, but this stone obviously violates the law of the universe.

Before coming, the chief specially met with him and told him not to be surprised by the novelty, to put down the shelf if he didn't understand, ask more, and learn more humbly, so Yang Weili nodded and said: "This stone will be given to me as a souvenir, please take me for a walk now." ”

"Director Yang, please!"

Qin Ling and Ye Lingshuang took Yang Weili and visited the base while introducing.

For Yang Weili, it was unreserved, in the Negative Energy Experimental Center, Yang Weili witnessed a void sphere being bent into a saddle shape!

In the engine manufacturing center, Yang Weili saw the conventional power system driven by the sun stone and the anti-gravity system driven by the spirit stone, and what shocked him was that he couldn't hold a small piece of engine parts the size of a palm!

In the quantum lab, he saw how the real-time transmission of quantum states at N distances was solved in quantum communication.

In the weapons manufacturing workshop, he saw the naval guns powered by spirit stones and sun gods, the thinnest has a caliber of 3 meters, and the caliber of the main gun in the bow has reached 20 meters, although it cannot be demonstrated on the spot, but according to the introduction, the main gun can retain 95% of the energy on the scale of 1 million kilometers, 80% of the energy on the scale of 10 million kilometers, and the instantaneous output energy has reached 8×10 to the 13th joules!

What is this concept? Equivalent to the energy released by the fission of one kilogram of uranium!

Although the power of the secondary cannon is far less than that of the main gun, the energy consumption and recharge time are much less.

Gradually, Yang Weili became numb!

But then, he was shocked again in the hull smelting room, because the hull is a whole refining and must be formed at one time, so the hull has not been built for the time being, but materials similar to the engine are placed piece by piece, and there are looming veins on the inside, according to reports, these veins play three roles.

The first is information reception, which is equivalent to the skin of the human body, receiving various light waves and electromagnetic waves in the starry sky.

The second is information transmission, which replaces all kinds of cables and wires, just like the nervous system of the human body, and transmits the received messy information to the main control computer for processing.

Finally, there is the anti-strike circuit, when the hull is hit by an external force, this vein can distribute the power to the entire hull in an instant, so that unless the enemy has the ability to destroy the entire starship with one shot, or the starship's energy is exhausted, ordinary strikes cannot bring damage to the starship.

And in the center of the base, there is the main control computer room, which is currently guarded by General Tie.

Because the main control computer will be made by Qingqing.

The fastest material speed in the three-dimensional universe is light, and any matter beyond the speed of light does not exist, so in theory, the light brain has the fastest speed of processing information, but don't forget, there is also a quantum theory, according to calculations, quantum entanglement states actually have speed, in 2013, the Chinese National Laboratory for Physical Science at the Microscale successfully calculated that the lower limit of the transmission speed of quantum entanglement states is 10,000 times that of light!

Specifically, the test of a pair of quantum simultaneous changes of the over-distance effect, this over-distance effect must be in an established optical channel, in an entangled state, when two quanta belonging to different locations change at the same time, the speed of mutual induction in the middle, can also be understood as the transmission speed of the signal.

Such a master computer is called a measuring brain!

Obviously, this is a standard black black technology, even cultivators can't do it, it can only be made by Qingqing from the six-dimensional space-time, although it is unknown how many times the speed of light can be reached, but even if it is a loss, it can reach 1000 times the speed of light, which is also a great achievement.

It must also be pointed out that the quantum entangled state is the transfer of state, which has the speed of mass and the limit is the speed of light, but it does not mean that the limit of the state transfer speed is the speed of light, and there is an essential difference between the two!
