"Xu Yang!"

"You can't eat this!"

Yang Xiaoman is making breakfast for her child. The two siblings are eating fruit nutritious cereals, plus about a cup of formula milk. These are almost all the best brands available in the country. When it comes to children's health, Xiaoman has always been

unambiguous.

And at this time,

The troublemaker Xu Yang was holding a carton of milk and stuffing it into his mouth... However, his mouth was too small and he couldn't stuff it in. He was so angry that he threw away the pure milk for his father to drink.

, as if he was still not satisfied with this, he was kicked again.

Xu Yang:(°ー°〃)

Well...

Give it to daddy!

"Dad~eat~" Xu Yang obediently picked up the carton of milk and put it on the coffee table. Just then...Xu Mang walked down the stairs with Ha Qie in his hand and happened to see this amazing scene.

I...

this...

I've always been eating this kind of thing emotionally?

Xu Mang almost didn't die from anger. Fortunately, Xu Yang was still young...otherwise he would have been beaten. Of course, if the murderer was Xu Man, Xu Mang might have let it go and even praised Xu Man happily.

, there is no way... who makes Xu Man his father's caring little cotton-padded jacket.

"Daddy~baby~"

Xu Man saw his father and opened his arms, expecting to be picked up by his father. Xu Mang did not hesitate...went up and directly took his daughter into his arms and said affectionately: "My dear daughter, what time do you want to get up today?"

?Did you sleep well last night?"

Xu Man didn't speak. He hugged his father's neck tightly and kept rubbing his little face against his father's. The affection between father and daughter was vividly displayed at this moment. Xu Man liked the way his father was so fond of him.

The idea of ​​having a third child came up.

Must be a daughter!

If you have two daughters, you are basically safe!

"Dad~"

"Hug~" Xu Yang saw his sister and wanted his father to hug him.

"Come on, come on." Xu Mang also held his son in his arms, but... the son was no match for his daughter after all. He came up and slapped Xu Mang directly, making Xu Yang laugh non-stop. This slap

Xu Mang was so angry that he didn't know how to beat this little bastard to death.

soon,

Xiaoman came to the living room with a bowl. When she saw her husband playing with the child, she couldn't help shouting: "Hurry up and bring her over... feed the child for breakfast."

Immediately afterwards,

With the help of their parents, Xu Yang and Xu Man finished their breakfast with great difficulty. Regarding the matter of their children eating...the couple had been going through hardships almost all day long, and had a battle of wits and courage with their children every day.

During the process, Xu Man was a little obedient, but Xu Yang... was very rebellious.

"well..."

"I'm so tired!" Yang Xiaoman looked at the children who were eating and playing, and said with helplessness: "Eating every time is like fighting, requiring the use of various martial arts, and even conspiracy.

...It’s just too tiring.”

"Can't you handle it anymore?" Xu Mang rolled his eyes and said with a bitter smile: "When Xu Yang goes to kindergarten in the future, you will be annoyed... With our son's level of mischief, he will destroy other people's kindergartens in minutes.

Remove it, just wait until your parents are called every day."

Not to mention,

Yang Xiaoman doesn't think her husband is fooling her. Her one-year-old son... makes trouble at home every day. Last time, he broke a lipstick and broke his father's car rearview mirror.

, I don’t know what will happen.

The two of them were still immersed in all the sad things that happened in the future, and over there... the little devil Xu Yang started his mischief again.

I didn't know where I found the remote control. I stuffed it into my mouth and found that it was too hard... I threw it out and hit the TV. Then... the screen of the TV was broken.

, and the price of this TV is really not cheap.

Xu Mang:(￣△￣；)

Yang Xiaoman:(￣△￣;)

It’s over!

One hundred and fifty thousand dollars was just gone!

This TV placed in the living room was brought back from abroad by Xiaoman. It was a top-of-the-line model from Samsung... The price at the time was US$150,000, and there were various tax issues.

The total price is about 170,000.

As a result...it was just scrapped, and I don't know if it can be repaired...

"husband..."

"Why don't you give me a beating?" Yang Xiaoman said angrily: "It's not a big deal to cause destruction every day."

"Forget it, forget it..."

"Hurry up and contact the manufacturer and ask how much it will cost to repair it." Xu Mang sighed and said helplessly: "The child is only so old now. If it gets damaged...who can we talk to for explanation? What about the child?

It’s not a TV. If it breaks, you can ask the manufacturer to repair it.”

"It's all your fault!"

"It's because you were so naughty when you were a child that your son is so naughty now." Yang Xiaoman thought of all the things that happened when Xu Mang was a child, and then related it to his son's current situation. The more he looked at it, the more it looked like the situation of her husband when he was a child.

Xu Mang smiled and did not dare to answer.

At this time,

The cell phone rang. It was a call from the research institute.

"Hello?"

"What's going on?" Xu Mang was eating cherries and talking on the phone.

"Academician Xu!"

"Our team just discovered a problem." The other party said hurriedly: "We found that the fine structure constant of the universe that should be constant in a galaxy has changed, and the change seems to only occur in that direction, as if it has been modified by someone.

.”

ah?

How is this possible!

Xu Mang's first reaction was negative, because there is a Lorentz invariance in the universe, which comes from Einstein's special theory of relativity.

"Which constant is it?" Xu Mang asked.

"a!"

a?!

Xu Mang's brows couldn't help but knit together, because the fine structure constant a of the universe is not an ordinary number. It is directly related to whether matter can be composed, whether planets can condense, and whether you and I can appear.

The fine structure constant of the universe plays an important role in natural science and is used to measure the intensity of electromagnetic force, that is, it can be used to measure the intensity of interaction between charged particles and electromagnetic fields.

It determines the properties of atoms and molecules, affects the interaction between electrons and protons, and determines their constraint energy and the binding energy of the nucleus.

If a is too large, then atoms and molecules cannot exist, the universe will not produce stars, and without stars, it is impossible to produce human beings. This a is so subtle and magical, and it is so fascinating.

"this..."

"Are you sure you're not mistaken?" Xu Mang asked seriously: "This discovery may rewrite the laws of physics we understand. You can't make fun of me casually."

"No!"

"I'm really not kidding." The other party said urgently: "We observed a quasar from more than 13 billion light-years away. It is probably a similar galaxy structure produced 800 million years after the Big Bang."

"We used a Roentgen ray spectrograph to observe this quasar for almost a month, and carried out four measurements of the universe's fine structure constant a. The results...this morning after comparing the measurement results in other parts of the universe, we

I found...the gap is very obvious." the other party said.

this...

What exactly is going on?

Xu Mang was completely confused. According to what the other party said, the physical laws in that area are different from those on the earth. If a nuclear weapon is exploded in that galaxy, the atomic bomb may fail because the a value may make the radiated atomic nucleus less likely to decay.

.

"I'll be right over!"

Xu Mang hurriedly hung up the phone, looked up at Xiaoman, and said seriously: "I'm going to work..."

"..."
