Xu Mang pondered for a long time about why the value of the fine structure constant a of the universe changed... There is still no answer. In his understanding... it may be because it changes constantly over time, just like the data representation of the microwave background radiation of the universe.

Compared with the current value of the fine structural constant a of its ancient universe... it must be reduced a little, as for how much it is reduced... it requires accurate calculations to know.

"should..."

"It means it is not a very large value." Xu Mang smiled bitterly. This problem is really tricky... Suddenly, a situation where the constant a of the fine structure of the universe becomes larger. If this is verified by the whole world, it is probably another major earthquake.

actually,

The method that affects the cosmic fine structure constant a can be seen from its expression, a=e^2/(4πe0c).. where e is the charge of electrons, e0 is the vacuum dielectric constant value, and c is easy to understand that it is the speed of light, and there is also a Planck constant.

The abbreviation is...a=e^2/hc.

In this case, there are three physical quantities that can affect the constant of the fine structure of the universe, namely the electron charge, the speed of light and the Planck constant.

The change of the value of the fine structure constant a, or the change of the three physical quantities, all or partly changes of the electron charge, the speed of light and the Planck constant... Is it because of the speed of light? But it is impossible... The increase in the speed of light is very huge.

Furthermore... Relativity theory is very stable, and the constant speed of light is an unchanging truth. Although seventeen years ago, scientists pointed out that the speed of light in the ancient universe was nearly one percent faster than today, Xu Mang felt... this may be due to the equipment at that time.

It is too dangerous to break the constant speed of light!

If the speed of light cannot be changed, then all that is left is the electron charge and the Planck constant, but...

Thinking about it,

Xu Mang stopped thinking because if you continue thinking, the consequences will be too terrifying... The value of the fine structure constant a of the universe affects the force of the electromagnetic field and the binding energy of the atomic nucleus. If this index fluctuates significantly, it may affect the composition of human beings.

The human body's cells mainly relies on the electromagnetic force of molecular bonds to condense together. The weakening of electromagnetic force means that the energy required to break the molecular bonds will be smaller. The intuitive feeling is that the human skin will be more susceptible to injury and the bones will be more fragile.

The value of the fine structure constant a of the universe that is too small will also lead to the lack of hydrogen in the universe, forcing the thermonuclear reaction to stop.

perhaps...

Xu Mang picked up his pen and calculated the value of the cosmic fine structure constant a to what extent would the universe change the structure... The final answer was four percent, four percent smaller than the existing value, stars would not be able to produce heavy elements.

If this value increases, the electrostatic repulsion between protons in the nucleus will increase.

In this way, due to the suppression of strong interaction forces, the increase in electrostatic repulsion will not have much impact, but large-mass atomic nuclei will decay more easily.

Regarding this,

Xu Mang performed another calculation, but the obtained value was that when the value of the fine structure constant a of the universe is zero or one percent more than now, the energy generated by nuclear fusion will not be enough to allow two hydrogens to synthesize helium, and the thermonuclear reaction will stop.

From then on... the universe lost its source of energy, and humans could only rely on the remaining heat source to survive.

If this value continues to increase, the electromagnetic force will become greater than or equal to the strong interaction force, and the entire universe will collapse directly and become fragmented.

"well..."

"Go home and go home..." Xu Mang was about to go home, but suddenly realized that he had just arrived at the unit and sat back on the chair silently. He started to daze alone... As he was speaking, Brother Chuan Xiao came to the door to ask about some funding issues.

Funding...

Xu Mang’s biggest headache now is funding. As the roads in the institute get bigger and bigger, more and more money is needed, but the funds are very limited... Although each time I apply for funding, I won’t say much, but I am a human being... If I keep applying, I will have opinions.

"What?"

"Is it so much money?" Xu Mang looked at Brother Chuan Xiao with a confused look: "This...is all the cost of equipment update and introduction?"

"right!"

"The treatment of employees has not been included. In short, this money is urgent." Brother Chuan Xiao smiled bitterly and said, "You also know... the road to the institute is getting wider and wider, and there are more and more places to use money. You have to find a way to attract sponsorship, otherwise it will not last for future operation by relying solely on this funding."

this...

This is over!

Xu Mang's biggest annoyance is to attract sponsorship, but the country's capital investment only accounts for two-fifths, and the rest is all supported by his wife, and it cannot be maintained forever... Otherwise, they will all go bankrupt, and the best way to find sponsorship is a pity that it is not his strength.

"I see..."

"I will solve the problem of funds." Xu Mang sighed and said helplessly: "Or why we should cooperate with universities in the future and we will pay part of the funds and let the other party fill the rest. If this continues, it will go bankrupt."

“…”

"Do you know too?" Brother Chuan Xiao said, "You should think of some solutions quickly... If this continues, it will last for a year or two."

"Oh!" Xu Mang nodded.

Immediately afterwards,

The sad and tired Xu Mang returned home.

...

"Xu Yang!"

"Let your sister go, you know you're bullying your sister at such a young age. What's wrong with growing up?" Yang Xiaoman was so angry that she was so angry that she shouted angrily: "I'll beat you to death now, so as not to harm other little girls in the future."

However,

Faced with her mother's scolding, Xu Yang ignored her and continued to play with her sister. In fact,... the siblings just had a conflict by chance. Even if there was a conflict, the effort was very light, but in my mother's eyes... Xu Yang was very heavy.

Seeing his son's noisy look, Xiaoman thought of the time when he met Xu Mang, this big pig's hoof... when he saw him, he started to touch him. At first it was just verbal harassment, but at the back... it was physical movements.

I guess my son will also take this path, alas... how can I live my life in the future?

Why did he give birth to such a son? Is Xu Yang really his own? Could it be that the hospital made a mistake?

Staring at my son's face,

Xiaoman felt that the chance of holding the wrong one was zero, because Xu Yang looked almost exactly the same as her husband Xu Mang, revealing a trace of bad temperament from her bones. She used to think it was too cute, but now she becomes more angry as she looks at it.

"Mom~"

"Hug~"

Xu Yang crawled to Xiaoman's legs and pulled her pants. Faced with the call of the child, Xiaoman put down the helplessness in his heart. When he picked up Xu Yang, he instantly swept away the previous haze. After all, this is his own son!

"Xu Yang... You must be more determined in the future. Now the thing that mom is most worried about is you." Yang Xiaoman sighed and said earnestly: "Look at dad... that's a great scientist. Look at mom and big capitalist. You must be more determined... You can't embarrass your parents, do you know?"

Xu Yang looked at his mother with a blank look on his face, not knowing what she was talking about, but he knew how to make his mother happy.

(*￣3(*￣▽￣*)可~

I'm so happy!

It was so happy that it exploded!

Yang Xiaoman smiled and pinched Xu Yang's face, and said happily: "Well... Mom's baby will certainly not disappoint her."

At this time,

Xu Mang returned home with his bag on his back and saw his wife holding her son but letting her daughter ignore her, and he was angry instantly... He scolded seriously: "Xiaoman...what is your situation? Xu Man doesn't care about it now?"

"What do you know!"

"I'm educating my son. The two little guys just finished fighting." Yang Xiaoman put his son down and said angrily: "I seriously suspect now... My son may go on your old path. He knows that he has bullied girls at such a young age. What's wrong with growing up?"

"I..."

"What's up to me?"

"When did I bully a girl?" Xu Mang frowned and said seriously: "Don't swear!"

"cut!"

"I don't know which bastard he is. When he saw me, he started harassing me... and was harassed as your wife." Yang Xiaoman glanced: "But... Is there any problem with my future daughter-in-law?"

Speaking of this,

Yang Xiaoman showed a motherly smile.

after,

Xu Yang and Xu Man were coaxed to sleep, while Xu Mang hugged Xiao Man. The couple looked at the child quietly, their eyes full of love, and the small room was already full of love.

"I really want to continue like this forever." Yang Xiaoman sighed: "But... we and our children will be separated one day. When we think of two little guys going to get married, I feel empty. Oh... I finally know why my parents cried so sadly on the day I got married."

Well?

No?

The situation was not...

"Wait a moment!"

"Why did my parents be so happy at that time from what I know?" Xu Mang said seriously: "You should not be a historical adapter!"

Yang Xiaoman felt so angry that such a peaceful atmosphere was instantly destroyed.

"roll!"

"I'm so annoying!"

"You won't go to work tomorrow, are you? Let's take your children to the amusement park together. Have you heard?" Yang Xiaoman twisted Xu Mang's soft flesh on his waist hard and said angrily.

...

In the afternoon of that day,

The Xu Yang Research Institute issued an announcement that shocked the world. In this mysterious universe, there are physical laws that are separated from human cognition.

And because of all the previous events,
