At night

On a bench in the park, Yang Xiaoman was lying in Xu Mang's arms, and at this time, Xu Mang was confirming the news with Professor Smith that the so-called American Astronomical Society had long had conflicts with the Princeton Astrophysical Society, mainly because of the fierce academic competition.

"Professor Smith?"

"I heard that at the International Astronomy Conference in a week, the American Astronomical Society will publish a research report on the binary star system of the constellation Sagittarius?" Xu Mang asked curiously, "Is it true? If it is true, it is very troublesome... I'm also working on the binary star system in the constellation Sagittarius. ”

Hearing Xu Mang's words, Smith was stunned for a moment, and hurriedly said: "How is your progress? If you can, compete with them, and it is best to publish the research report on the binary star system of the constellation Sagittarius before the start of the International Astronomical Conference, so that the American Astronomical Society will be depressed for a while." ”

“...”

"Looks like Professor Smith, our minds collided. Xu Mang said with a smile: "But I need financial support, and at the same time I need a little bit of equipment support, otherwise I can't guarantee that I can successfully research before the international astronomical conference." ”

"Don't worry!"

"We'll do everything we can to help you, after all, you're a core member of our Princeton Astrophysical Society. Professor Smith smiled, "Xu Mang... Post the success on the homepage of our association and I will promote it. ”

"Good!"

"I will!" Xu Mang said, "I'll hang up first." ”

syllable

Hang up the phone,

Xu Mang glanced at the girl in his arms, with a hint of shyness between his eyebrows, although he didn't know why this situation happened, but he could imagine... At this time, Xiao Man was full of an inexplicable impulse, if it weren't for the fact that in a public like the park, I'm afraid... His life is gone.

"Husband..."

"Let's go home!"

"Oh. ”

This night,

Nothing happened, but Xu Mang knew that the real challenge would be tomorrow night.

Following

Xu Mang returned to his place of work, there was no one in the entire institute today, after all, all of them were on vacation, and Xu Mang was not a black-hearted boss like Xiao Man, forcing his subordinates to work hard, eager to work sixteen hours a day, all year round.

Sitting in his office, Xu Mang opened his mailbox, and sure enough, there was an extra email in it, and he clicked to see that it was Professor Smith who sent him information about the binary star system of Sagittarius.

I have to say,

This information is very detailed, much more detailed than what he and Brother Chuan Xiao collected, and sometimes it is true that in the field of cosmology, developed countries are indeed very advanced, and this must be admitted, China still has a long way to go.

According to the current development situation, the pace of catching up is quite positive, and efforts are being made to explore space, Fat Five has succeeded again, and the Taibai Cat Mars rover is ready to go, everything is ready, just wait for some details.

Next

Based on the information obtained, Xu Mang began to conduct a more in-depth study of this star system, and could not help but find that this binary star system is different from the others, to be precise, it is a unique existence, it is 100 times brighter than all other known eclipse binary stars, and it powers huge stellar winds, equivalent to the wind before the death of the most massive star.

And these two extreme properties are due to the fact that normal stars are four times more massive than white dwarfs, and of all other known eclipse binaries, white dwarfs are more massive than normal stars orbiting them, which are just the opposite.

So far

Xu Mang made a relatively complete physical model, according to which he basically predicted the fate of the binary star system in the constellation Sagittarius in the next few decades, which will spiral rapidly as the brightness increases, and inevitably, this spiral rotation will reach a climax, and most of the gas in the normal star will fall on the white dwarf in the last few weeks and days.

In this falling mass will unleash enormous gravitational potential energy that will propel an unprecedented stellar wind, all of which will peak in the last few weeks and days, while the Big Bang time will reach its peak brightness within a month, merging the two stars into one.

At last

The result of the merger will produce a single star with a degenerate white dwarf core, a hydrogen-burning layer, surrounded by a massive gas envelope, most of which is hydrogen.

It's exciting to think about!

Xu Mang is 100% sure of his predictions, all of which use standard equations that describe many physical mechanisms, and although it is not yet possible to calculate the exact time, a strong answer has been given.

But

It is now also possible to calculate the time, based on the brightness of the time when the merger according to the spiral occurred. The uncertainty of this date plus or minus sixteen years, the huge intrinsic jitter in brightness from the historical record, does not perfectly measure the time scale of doubling.

therefore

This date is likely to be around 2100, or between 80 and 100 years to be more precise, most likely near the middle of this range.

"No way!"

"You have to calculate the exact time!" Xu Mang's head instantly hardened again, and he was stubborn that he had to calculate the specific time, otherwise he felt very uncomfortable.

however

He overestimated himself, and spent an hour in the morning, unable to calculate the specific explosion time, and couldn't help but give up, unless he could provide more brightness galaxies, he couldn't find any way from some of the current data.

...

Afternoon

Xu Mang drove to Xiaoman's company, and sure enough... One-third of them stay in the company and work overtime, there is no way... Triple pay is no joke, three days is the normal ten days.

"Huh!"

"Look at yourself... Black-hearted boss!" Xu Mang sat in front of Xiao Man and said with a disgusted face: "Do you know what a legal holiday is? That is, the law fixes that this day is rest, and what about you? Look at what you call it, this is called a crime!"

"Knowing the law and breaking the law... Sin plus one degree. Xu Mang said solemnly: "Someone is coming... Pull it out and cut it!"

Yang Xiaoman:

Damn it!

This bastard is shitty again,

Every day I make my wife angry, waiting for a child... I'll give you to the eunuchs!

"Humph!"

"You're screaming now... Look at the old lady, I won't be able to kill you in the future. Yang Xiaoman said angrily: "Anyway, where are you going to eat at night?"

"Of course, it's a French meal!" Xu Mang said with a smile: "I just booked a place, right... By the way, I also booked a room in the hotel, and... I went to the supermarket and bought a couple of gun holsters. ”

After that,

walked up to Xiao Man, grabbed her Qianqian's hand, put it into her pocket, and said with a wicked smile: "Hey, hey, hey." ”

"Badass!"

"You know to bully me all day long. Yang Xiaoman glanced at him, pouted his little mouth and said, "Husband... Why do I have a delusion?"

"Huh?"

"What delusion?" Xu asked.

"You don't love me at all!" Yang Xiaoman pouted and said: "I didn't buy a diamond ring, and I didn't have a decent marriage proposal, so I got married in a daze... You're always perfunctory to me, and if I didn't really love you, I would have hacked you to death a long time ago. ”

Xu Mang shrank his head, his face was full of embarrassment, but soon his waist stiffened again, isn't it just to make up for these two mistakes today?

"Oops..."

"It's all old husbands and wives, and they're still struggling with this matter. Xu Mang pinched Xiao Man's face and said helplessly: "What... I'll make it up to you later!"

"Humph!"

"Big liar!" Yang Xiaoman glanced at Xu Mang: "When will it be in the future?"

"Hey, hey. ”

soon

Xu Mang took Xiao Man to the city center, although it is not a kindergarten, but for Xiao Man, this arrangement is quite satisfied, a romantic meal and a romantic Ferris wheel for two people, is this big bastard enlightened?

Nearly 10,000 yuan was eaten in one meal, and when it was time to settle the bill, Xu Mantian shamelessly took this Xiaoman's bank card and went to settle the account, which made the violent airport angry, and he wanted to bite him to death.

In the next time, Xu Mang took Xiao Man's hand and walked on the crowded troubled streets, but as usual, Xu Mang was mistaken by others for a pet sister madman, a patient who was about to enter the German Orthopedics Department.

In the face of these gossips, Xu Mang didn't bother to explain anything, anyway, justice is in the hearts of the people, and the truth will be revealed one day.

night

Descending on the city,

It touched the hearts of many couples.

Xu Mang and Yang Xiaoman sat in one of the cockpits of the Ferris wheel, looking at the city in front of them, each of them had their own ideas, especially Xu Mang... As a fully automatic Modu person, I am very melancholy in my heart.

But

Yang Xiaoman thought differently, and secretly glanced at the man next to him, in his twilight years and the rest of his life, the love in his eyes was exactly what he was.

For a long time,

I'm really blessed to have you.

suddenly

Xu Mang took out a box from his trouser pocket and said indifferently: "Here you go!"

Yang Xiaoman: ???

What's that?

This box... Why does it look so much like a diamond ring?

Yang Xiaoman opened the box, and saw a super large diamond ring, and couldn't help but be startled, Xiaoman, who has been paying attention to the diamond ring, instantly gave an estimate of this diamond, which is at least more than 30 million!

Oh, my God!

He... Secretly bought a diamond ring?

"Wife?"

"Huh?"

"Marry me?" Xu Mang said with a sincere face, "Okay?"

Yang Xiaoman:

Propose?

Is this proposing to me?

Why is there no wave in my own psychology?

Damn it!

He turned the romantic proposal environment into a street grocery shopping environment.

"Don't!"

"It's so easy to marry you?" Yang Xiaoman said angrily: "The marriage proposal on people's TV is romantic and touching, why does it feel like going to the vegetable market to buy vegetables in your mouth, bland and full of boredom?"

"You do it all over again!"

"I moved my mother to death... Otherwise blow your dog's head out at night. Yang Xiaoman said angrily.

Yes?

Isn't that what a marriage proposal is?

Marry me?

Good!

And then the proposal was successful...

Looking at Xiao Man in front of him, Xu Mang thought for a long time, and he decided to weave a lie, the most touching and poetic lie in history.
