at the same time,

Yang Xiaoman and Guo Tianmei were hiding under the shade of the tree and chatting. Suddenly, they saw two barbecue tool guys sitting next to two other returnee girls holding chairs. The four of them started discussing some issues, and even took out their tablet computers from their bags and began to analyze the issues.

What's going on?

Didn't barbecue well and suddenly started to solve the problem?

Could it be

Are all those who have studied abroad so bored?

Need to perform accurate calculations in barbecue?

“What’s the situation?”

"What's going on with these four guys?" Yang Xiaoman frowned and asked Tianmei beside him: "What the hell is it together?"

"have no idea."

"But one thing is certain that these four people are not interested in barbecue." Guo Tianmei said: "Anyway, these four people are very high-end, especially those two boys, who know whether they are talking about the concept of black holes. Then the four people fought over this concept in the car for a long time. It seemed that I didn't know what the problem was, it seemed to be a calculation problem."

"cut!"

"It's not that I deliberately belittled these four people. Your Brother Xu Mang is an authoritative expert in this regard." Yang Xiaoman showed a disdainful expression and said with contempt: "Forget it, ignore these four people, I'm not a member of the road anyway."

On the other side,

Tong Min, Lu Bo, Liu Yanhe and Zhao Pengpeng were in trouble. The four of them were not interested in barbecue and took this opportunity to start solving the problem of the expansionary universe concept in relativity cosmology, but the four of them encountered obstacles.

One problem is already tragic. If energy and momentum are respectively, assuming that particles will propagate freely in addition to being affected by the above metrics, how can we calculate the energy and momentum and time ratio?

How do particles’ thinking kinetic energy be described as kinetic energy?

How to calculate the particle energy from r^)= constant?

The four of them fell into an embarrassing dilemma when calculating the functional relationship between energy, momentum and time of the expansion universe.

Half an hour,

It took half an hour, and there was no clue.

At this time,

A sound came out behind him.

"Your mutton skewers are ready!"

Xu Mang held a handful of mutton skewers and stood by the side with a smile on his face. Suddenly, he stretched his head and looked at the calculation process on the hands of the four people, and asked curiously: "What are you doing?"
