Thanks to the silver husky for the monthly pass and the panda de dinner for the tip-

"Who are you?" There was no information about this person in Wu Chen's memory. is also because of the relationship between the fusion of time and space for thousands of years, Wu Chen is even more uncertain which plot world he immigrated to the moon from.

"Mirajanko? Minovsky, you can call me Mira. The local, dressed in a miner's uniform, hurriedly replied.

"Mira, this gentleman is from Earth and will not be interested in your stuff." The clean, spotless high-tech nano clothes worn by Wu Chen and the others already hinted at their identities, and the hostess spoke.

"Okay, Penny." The disappointed miner was about to leave, but was stopped by Su Yueming.

"Wait."

"Good day, ma'am." Mira hurriedly saluted.

"What do you want to sell?" Su Yueming asked curiously.

"Oh, it's this." Mira scrambled to take out a silver metal ball from her backpack.

The metal balls had apparently been carefully tended by their owners, reflecting a clean light that was very different from the environment.

Almost at the moment when the miner took out the silver metal ball, Wu Chen subconsciously felt numb, and his scalp was about to explode.

It's as if the miners pulled out an extremely dangerous miniature nuclear bomb!

"What is it?" Su Yueming didn't react at all.

"I call it the little fire dragon, it's me...... A hand warmer made of it. ”

"Hahaha......" The group burst into laughter.

Su Yueming pursed her lips, but there was a smile on her face: "Okay, Mira." Tell me. Why buy your hand warmer? ”

There was no one around the miners. Endless boasting: "First of all. The moon's nights are long and cold. Even those powerful life-sustaining systems could not withstand the cold of the moon. Think about it, what a pleasant thing it would be to have a warm and warm little fire dragon in the company of a long night! ”

The Moon does not have an atmosphere, so the temperature difference between day and night is extremely large. Although the head is covered with a high-tech diaphragm, the temperature retention is still limited. Maybe the people who live here can feel the same way, but for the people who live in the high-tech main base, Flash Butterfly and others. That's not a problem.

"And then?" Signaling Shandie and the others to be restless, Su Yueming asked with a smile.

"Secondly, as long as my little fire dragon is lit, once and for all, there is no need to change the fuel."

Su Yueming smiled: "Energy slurry battery, thermonuclear furnace, or quantum circulation?" ”

"It's not ......," Mira shook her head firmly, "yes...... Well, it should be chemical energy. ”

Just as most acid-base neutralization reactions release heat, Mira's so-called chemical energy should be a similar exothermic reaction.

"Chemistry." Su Yueming immediately lost interest. As far as she knew. No chemical reaction can continuously release heat without replenishing the reactants. Apparently. The miner was not as honest as he appeared.

Wu Chen suddenly asked, "What else?" ”

Holding back her courage, Mira finally spoke: "You just said that money doesn't mean anything to you, so I want you to buy it." Because, money means a lot to me. ”

"How much do you want to sell?" Wu Chen smiled and spoke.

"5,000, preferably 10,000 points."

As soon as the words came out, there was an uproar.

The points mentioned by Mira refer to the current top purple value points in New Hong Kong. It can be exchanged 1:1 with resource points.

As we all know, permanent residency on the moon is expensive.

Su Yueming's offer price is 100,000 value points. It stipulates that the upper limit of red protection points is 9,000, the upper limit of orange support points is 10,000, the upper limit of yellow reward points is 10,000, the upper limit of green credit points is 20,000, the upper limit of cyan merit points is 20,000, the upper limit of blue contribution points is 30,000, and the lower line of purple elite points is 1,000.

Referring to the value system of New Hong Kong, players need 1000 points if they use resource points to buy Moon Residency.

Therefore, Mira offers 10,000 purple value points for the 'Hand Warmer', which is equivalent to 10,000 resource points. It is possible to immigrate 10 people to the moon. So as soon as the words fell, the whole bar was noisy.

"Mira, you're crazy. 10,000 points? I can immigrate to Earth with my whole family! ”

"Not really!"

"This gentleman, he's a madman! The last time I came to me, I only offered 3,000, good guy, all of a sudden it rose to 10,000! The spaceship is not as fast as him! ”

The abuse and ridicule of everyone did not make Mira flinch, although she was shrunk in the miner's uniform, her bloodshot eyes were staring at Wu Chen's reaction.

"I'll give you 10,000 points."

With a "hum-" sound, the whole tavern exploded!

Because a madman even crazier than Mira has appeared!

Hearing Wu Chen's words, Mira's wide-open eyes suddenly blinked stiffly. In the gray and clear eyes, tears of excitement are surging rapidly.

"I'm out 11,000 points." Su Yueming smiled and blinked: "Sell it to me?" ”

Wu Chen had to admit that once Su Damei laughed, she was really beautiful.

"No, ma'am." Mira shook her head firmly: "I promised this gentleman. Sell for only 10,000 pips. ”

I don't know when the tavern became dead silent, the waitress swallowed her saliva and quietly raised her hand: "I can connect to the Hong Kong bank here." ”

"Okay." During the whole process of trading, Mira was in a trance and completely lost her sense of existence. As he said to Wu Chen, these 10,000 points are really important to him.

As for the true value of hand warmers, miners who have experienced too many setbacks and failures, as well as grief and despair, have no time to scruple.

"Mira, go. Mina is waiting for you. The waitress gently patted Mira on the shoulder, and her eyes were filled with tears.

"Hmm!" The waitress's words woke up the miner in one fell swoop, and after a deep look at Wu Chen, Mira snatched the bearer bank card and turned around and ran out.

After taking the hand warmer from the hostess's hand, Su Yueming looked at it curiously, and made sure that she couldn't see why she came. Instead, he handed it to Wu Chen: "You don't want to ask who Mina is?" ”

"I don't want to." Wu Chen stretched out his hand to take it. The warmth between her eyebrows and eyes made Su Yueming's heart flutter.

She loved this man to death.

Estimated for a long time. I can't even drink this wine.

Under the gaze of countless complicated eyes in the audience, everyone hugged their heads and scurried.

"Hahaha......" squeezed through the crowd, Wu Chen and Su Yueming ran wildly all the way, and when they rushed into the empty subway, the two looked at each other tacitly and laughed out loud at the same time.

After the settling account, the Butterfly team caught up, and Wu Chen and Su Damei of you and me immediately stepped on the subway on the return journey.

Saying goodbye to Shandie and the others, Wu Chen walked into the bedroom arranged by the base Zhizhi with Su Yueming in his arms.

"How do the masters go to those dirty places." Take a bath while Su Da is a beauty. The robot servant who was captured by the Red Queen's decoding hurried to meet him.

"Fortunately, although the bar conditions in the mining area are poor, they are better than lively." Wu Chen, who didn't feel anything wrong, took off his nano suit and walked towards the bathroom.

The Red Queen was about to ask, when she was suddenly attracted by the fluctuations coming from under Wu Chen's nanosuit, "What is this?" ”

Wu Chen then remembered: "It is said to be a hand warmer." But I don't think it's that simple. ”

"Leave it to me." The robot servant flickered at the silver-white metal sphere and entered the working state.

When Wu Chen walked out of the bathroom with Su Yueming, who was soft, put in the big bed, kissed the beauty's cheek and watched her fall asleep, the Red Queen also completed the preliminary analysis.

"The hosts. This ball is not simple. As soon as the Red Queen spoke, Wu Chen's interest was aroused.

"Tell me about it." After covering the quilt for Su Da Beauty, Wu Chen walked out of the bedroom gently.

"The inside of this sphere that is constantly releasing gravitational waves to the outside world. Fermions in their superfluid state should be sealed. "The Red Queen was very high-end as soon as she opened her mouth.

"Gravitational waves? Superfluid? Fermion? Wu Chen, who had just emptied himself, was not running at all.

"There are two isotopes of helium-3 in nature, 3He and 4He. The nucleus of 4He has two protons and two neutrons, called bosons; Whereas, 3He has only one neutron, which is called a fermion. In the late 30s of the 20th century, mankind discovered the superfluidity of 4He: when the temperature was at an absolute temperature of 2.17K (-270.98 degrees Celsius), the 4He atom underwent Bose Einstein condensation and became a superfluid. That is, when the temperature is low enough and the motion of the atoms is slow enough, they will concentrate into the same quantum state with the lowest energy. At this point, all atoms have exactly the same physical properties as if they were one atom. When the temperature is absolute zero, the phenomenon of thermal motion disappears and the atoms are in an ideal Bose Einstein condensation state.

The theory of superconductivity of metals, also known as the BCS theory, led to the belief that 3He may also form superfluids at very low temperatures. However, people have not been able to find the superfluidity of 3He experimentally. It was not until the 70s of the 20th century that humans finally verified the superfluidity of 3He. ”

"What's so amazing about the super-liquid 3He?" Wu Chen tried to gather his demigod-level thinking.

"The discovery of 3He superfluids has a peculiar application in astrophysics. The 3He superfluid was used to test theories about how cosmic strings were formed in the universe. This is done by rapidly heating the superfluid 3He locally with a nuclear reaction caused by neutrinos, and when they are recooled, some vortex spheres are formed. These vortex balls are the equivalent of cosmic strings. ”

"Well, what's the cosmic string again?" Wu Chen seemed to have heard it somewhere, but he couldn't remember it for a while.

"At the beginning of the Big Bang, the power generated in a very short moment between 0 and 1 second was formed into countless thin, long, and highly concentrated 'tubes'. This pipe is called the cosmic string. It's a bit like spider silk, but it's much thinner than an atom. However, a centimeter of cosmic strings is larger than the mass of the entire Himalayas, and the mass is variable and depends entirely on its tension: the longer it is pulled and the tighter it is taut, the greater the mass. Its tension is about 100 trillion trillion tons. This makes the cosmic string very stretchable.

Suppose there is a cosmic string tied to the Earth, which can accelerate the Earth to 2899 km/h in 1 second! Cosmic strings existed at the beginning of the Big Bang. As she slowly stretches out and spreads across the universe to form the existing four-dimensional space, as the mass gradually spreads outward, the cosmic strings will release gravitational waves similar to electromagnetic waves. ”

"The universe we live in is covered with cobwebs called cosmic strings. If you tie a spider silk to the earth, the earth can accelerate to 2899 km/h in 1 second......" Wu Chen suddenly woke up: "Are you telling me about time travel?" ”

"That's right!" The Red Queen looked excited.

"Stop." Wu Chen shook his swollen head and returned to the origin of the question: "Wasn't the superfluid of fermion discovered a long time ago?" ”

"That's right, the superfluid 3He is heated locally quickly with a nuclear reaction caused by neutrinos, and when they are recooled, some vortex spheres are formed. Please note: 'Nuclear reactions caused by neutrinos', 'local rapid heating' and 'some vortex balls'! ”

"Nuclear reactions, local heating, some vortex balls." Wu Chen understood, "The experiment is not perfect. ”

"That's right! But the metal ball in the owner's hand is a perfect "fermion superfluid vortex"! The more the Red Queen spoke, the more excited she became: "The perfect fermion superfluid vortex echoes one of the cosmic strings!" Master, your discovery will soon put an end to quantum teleportation! ”

"So, it's worth 10,000 points." Wu Chen said with a smile.

"......" The master's thinking is really jumping!

"The question is how do you tie the earth to spider silk?"

"It's not a tie, it's an inhalation. Don't forget, hosts, they're tubes! Pipes that extend like spider webs! ”

"Okay, but how do I know which pipe to get out of?"

"Haha! Gravitational wave! ”

"How?"

"A gravitational field in which gravitational waves propagate in the form of waves and with finite velocity. According to the general theory of relativity, an object with mass emits gravitational radiation when it is accelerated, so the mass moving at an accelerated rate produces gravitational waves. The main property of gravitational waves is that they carry energy and can be detected! ”

"Still don't understand." Wu Chen has a big head.

"Space-time is distorted by massive objects, resulting in space-time distortion. When the gravitational waves produced by the Big Bang at the beginning of the universe are close to massive celestial bodies, such as neutron stars, supernovae, black holes, stars, the sun, the earth, Mars, the moon, etc., the degree of distortion of space-time is also different because of the different masses of these celestial bodies! If we compare the primordial gravitational waves, the difference between the two is a parameter unique to a certain planet! ”

"I kind of get it......"

"I need time...... Mmmm, I can handle that...... Master, wash and sleep! ”

“……”

The madness of the Red Queen finally came to a crazy end to this crazy day. (To be continued.) )
