Other methods?

Xu Mang's words aroused the suspicion of everyone in the lecture hall, and whether the so-called other methods were Xu Mang's brand-new research results? Regarding what was going to happen next, there was a trace of expectation on everyone's face.

At this point,

Yang Xiaoman, who was sitting in the middle of the front row, looked at her husband on the stage, with that high-spirited appearance, and had no other emotions in her heart except pride, but... She also felt a lot of pressure.

Finished

This big fool is getting better and better, what can I do?

Yang Xiaoman is not worried that he will not be worthy of him, but... Afraid of Xu Mang's gradual rise in status, he will have to face more temptations, the temptation of money seems impossible, and the beauty...

It doesn't seem possible, he has such an invincible and lovely beautiful girl as his wife, what else does he want?

Xiao Man was worried that the higher Xu Man stood up, the heavier he would fall.

If it fails,

Then he will definitely be pointed out by Qianfu, no matter how thick-skinned he is, he still looks like the king of salted fish, but public opinion is like a knife, it never asks whether it is right or wrong, it only cares about its own feelings.

Alas...

Big Fool,

Under the appearance of giggling, I don't know how much pressure you are under.

Initially

Yang Xiaoman felt that he was very tired, there were so many people up and down the management company, and there were two companies that were quietly launched, and every time he went home and saw Xu Mang's leisurely appearance, he felt angry and felt that it was unfair to be a man.

But... He's the one who is the most stressed!

smile

It's just a means of cover-up.

Looking at the curiosity on everyone's faces, Xu Mang coughed lightly and said indifferently: "Not long ago... A friend of mine named Sun Chuanxiao stumbled upon some secrets about white dwarfs and came to the conclusion that terrestrial planets may be common in the universe. ”

“？？？”

“？？？”

“？？？”

Xu Mang's words caused an uproar in the audience, the so-called terrestrial planets are similar to earth planets, and they are planets with silicate stone as the main component.

The terrestrial planet is roughly a metallic center dominated by iron, and the outer layer is surrounded by a silicate mantle. Their surface generally has canyons, craters, mountains, and volcanoes.

However, it is still very difficult to find terrestrial planets in the universe, and there are only a few endoplanets that are really known to mankind at present.

"Professor Xu!"

"I don't know if this friend of yours is a professional astrophysicist, I suspect ... He lacks basic common sense. A young man raised his hand and said, "Three years ago, NASA updated more than 200 exoplanets, and only about a dozen of them are terrestrial planets. ”

"If terrestrial planets are common in the universe, it should be a lot of announcements. The young man said.

This guy's speech was also what other people wanted to ask, and everyone stared at Xu Mang, their eyes radiating a longing light.

In fact

All this was what Xu Mang expected.

Even if he speaks wildly, it is impossible to move some people, and even a small rub of people is a dead brain, and he doesn't believe it when he is killed.

Evidence!

Only evidence can conquer these people.

Xu clicked on a two-dimensional data model, which showed an elemental comparison of five white dwarfs and solar system objects.

"As you can see. ”

"Elemental comparison diagram of a white dwarf star with a solar system object. Xu Mang stood in front of the podium and said to the five or six hundred people in front of him: "If you just observe a white dwarf, you may only see hydrogen and helium, but in these data, you can find the actual substance." ”

"Such as silicon, magnesium, carbon, and oxygen, which accumulate from the stars orbiting the white dwarf. Xu Mang paused for a moment and continued: "When iron is oxidized, it shares electrons with oxygen, forming chemical bonds between them. ”

"We can see this oxidation when the metal turns into rust, and the oxygen steals electrons from the iron, producing iron oxide instead of iron metal. Xu Mang said seriously: "My team and I measured the amount of oxidized iron in the rock that hit the white dwarf. ”

"As a result..."

"These white dwarfs have been found to be chemically similar to rocks from Earth, Mars and other parts of the solar system, and contain surprisingly high levels of iron oxide!" Xu said.

Words fall,

Xu Mang provided another data model diagram.

This...

This is absolutely big news!

Everyone present was shocked, perhaps in the eyes of outsiders, Xu Mang's discovery was quite ordinary, that is, it was determined that terrestrial planets are very common in the universe, but for astronomers and astrophysicists, this is absolutely shocking.

But...

These data model graphs alone do not seem to be convincing.

Followed by

Xu Mang threw out a concept - oxygen escape.

The oxygen fugitiveness is the effective partial pressure of oxygen, which refers to the partial pressure of oxygen under the total pressure of the mixed gas, which can be directly measured.

Many people present felt a little lost, is this related to oxygen escape?

"Perhaps... You guys don't really have anything to do... However, a large amount of iron in the silicates of chondrites is combined with oxygen, indicating that the earliest stage of the formation of rocks in the solar system has a high degree of oxygen fugitiveness. ”

"The increase in oxygen fugitability during the formation of rock masses is due to cosmic dust rich in water or rocks. "After that, I studied whether the process that causes the oxidation of rocks in the solar system is the same as that of other planetary systems. ”

"And the object is five white dwarfs. ”

"As a result..."

As soon as Xu Mang's voice fell, he provided a third data map, which clearly showed that there was a striking similarity between the two.

afterwards

Xu Mang published an important formula, the conversion formula for oxygen fugacity, which is not complicated, and even outrageously simple.

However... The reaction of everyone present was a little excited.

this

Definitely a revolutionary discovery!

Step by step, the mystery is becoming clearer, and the truth is getting closer and closer!

"Old man..."

"Can you tell me where Xu Mang's potential is?" Silke hurriedly turned to Professor Smith beside him as he looked at the stage explaining how to use the oxygen fugitiveness conversion formula.

"I don't know. ”

"Maybe only he can't think of it, but he can't do it without him. Professor Smith smiled wryly: "Who do you think this year's Nobel Prize will be given to?"

"Is this still a guesswork?"

"Who else but him can win the Nobel Prize in Physics?" Professor Silke said solemnly, "I hope that the Nobel Prize Committee can be fair, and let go of the inherent paranoia, if... This Nobel Prize in Physics was not won by Xu Mang, and I will not pay attention to them in my life. ”

Professor Smith nodded, he had the same idea.

meanwhile

Professor Danny of NASA was dead-faced, and when he slowly figured out Xu Mang's discovery, he realized how ridiculous the joint research topic of NASA, JXAX and Princeton University was.

By first observing the celestial bodies with gravitational microlens, and then calculating the oxygen fugitiveness value, he can basically figure out whether this planet is a habitable planet or not, and his method directly refreshes the cognitive view.

How did he come up with such a convenient and efficient idea?

"Professor Danny..."

"Are we still going to publish the results?" asked one of Danny's fellow researchers, cautiously.

Unveil?

Isn't that a joke?

Professor Danny smiled wryly and said silently, "Forget it... As if it had never happened. ”

The lecture hall continued, but it was nearing the end, and everyone here had been impressed by Xu Mang's research findings, and they couldn't imagine that they could come to an astonishing conclusion just by calculating the oxygen fugitiveness values of alien rocks and Earth.

If the values between the two are similar, then the terrestrial planets have the same plate tectonics and similar magnetic field potential as Earth, which happens to be a key ingredient in the origin of life.

...

It's over

This three-hour report finally came to an end after Xu Mang's departure, and almost at the same time... The news about this report has swept the world.

"The first steps to colonize space have been established!"

"Huaguo announced that it will actively cooperate with other countries to jointly establish a global lens anomaly network!"

"Shocked! Professor Xu Mang's research on WD reveals that the earth is not alone in the universe!"

At this point,

A large number of shocking headlines appeared, making it to the front pages almost at the same time.

At this moment,

The fields of astrophysics and astronomy are accelerating the progress of change, and while enjoying the innovation brought by Xu Mang, they are also worried about how to cope with the upcoming changes.

A lot of systems, a lot of equipment, have to be updated!

otherwise

will be abandoned by this era.

On the end day,

Yang Xiaoman was helping Xu Mang sort out his things in the background, and he would have just left like this, but this big fool didn't want to live or die, and said that he was wearing a dress on the street, just like a clown.

Helpless

You can only change into your usual casual clothes and go back to the hotel for a break.

"Big fool!"

"When did you prepare the flip-flops?" Yang Xiaoman found that in the corner of the small suitcase, there was a pair of flip-flops, and his handsome little face was full of sorrow: "You... You're not going to go out in slippers, are you?"

Xu Mang nodded and said with a smile: "What's not to do? After all, the weather is so hot!"

Then

Professor Smith and Professor Silke came to the rest of the lecture hall and saw Xu Mang and his wife staying together, Professor Smith said, "Xu Mang... Congratulations!"

Xu Mang smiled: "Professor Smith... Seriously... Next time, you'll have to help me prepare a bigger lecture hall. ”

"Yes!"

"I didn't expect there to be so many people this time. Professor Smith said: "Let me introduce you to Professor Silke, a world-renowned astrophysicist whose main research direction is high-energy astrophysics. ”

Xu Mang: (°ー°〃)

I don't know...

Who is it?

"Xu Mang!"

"Your presentation was brilliant and I was amazed. Professor Silke smiled and said, "I have a small problem here, and I hope you can help me solve it." ”

Professor Smith frowned, glancing at his old friend.

Questions?

This is a problem that has been bothering you for half a year!
