you come from the sky

The cafeteria in 201 is a bit different from the one in the Chinese Academy of Sciences. Nine out of ten people queuing up are wearing plastic glasses with thick lenses, many of them are skinny, and they mutter a lot. Looking at them, they look like they have entered a madhouse.Fang Haochen said that because researchers from the two research offices come to this cafeteria, many researchers in 201 don’t like to eat. They think that eating too much will affect their thinking and make people stupid. For them, eating an egg , is completely sufficient.

"That's a pity for the delicious food in 201." Among the group of people, Bian Yu felt that he was probably the only normal person. When he was waiting in line at the window, he glanced at the food outlet in 201. The dishes were also better than those of the Chinese Academy of Sciences. Many, eating meat once a month in the Chinese Academy of Sciences is not bad, but here in 201 is very generous.

"You are Dr. Bian Yubian."

Before Bian Yu could speak, the aunt in the cafeteria said with a smile.

"You know me?" Bian Yu lost his temper a few days ago, and his poker friends brought the food for him, so today, this is the first time he came to the cafeteria in 201, and he never thought that he would be recognized. come out.

"Yeah!" the aunt said, and gave Bian Yu two vegetables and one meat, Xu took care of the newcomer, and specially gave him two extra pieces of meat. After finishing the dishes, the aunt took another look at Bian Yu, "and Director Fang said the same thing, he looks really handsome."

Bian Yu paused, but soon he smiled, the corners of his mouth almost reaching his ears, he turned his head and glanced at Fang Haochen who was standing beside him: "That's what he said?"

"Yes." The aunt said with a smile, "Director Fang said that Dr. Bian is very handsome."

"I never said that." Fang Haochen answered with his lips tightly pursed and his head lowered. He kept complaining in his heart that the auntie in the cafeteria had a problem with her comprehension. Is it summed up by the phrase "handsome and conspicuous"?The generalization is fine, the meaning is biased.

But Bian Yu didn't seem to care about the truth of the matter at all, he squinted his eyes and smiled, two pear dimples stopped at the corners of his mouth, like that, he has never been so happy since he came to 201.

The two sat down with the bowls and chopsticks, Bian Yu didn't speak, just watched Fang Haochen eat with a smile on his face.

Fang Haochen was a little hairy under his stare, but he couldn't say anything if he wanted to refute, his ears were red and he didn't know whether it was from embarrassment or restraint, so he could only ignore it and bury his head in his meal.As a result, he buried his head in two mouthfuls, and then remembered that Bian Yu, a "weird", didn't like to just eat, and had to talk to him.

"What do you want to say?" Fang Haochen slowed down his eating speed, and looked up at Bian Yu.

"Don't say anything, wait for you to say." Bian Yu returned, the corner of his mouth still had a smile just now, "You should have a lot to say, today you can say whatever you want, I will listen."

Of course Bian Yu wanted to know how much he wanted to say to Fang Haochen.After all, Fang Haochen is like this every time he sees Bian Yu, his mind is full of research projects.I had been estranged from him for more than a week before, and it was still quiet, but now Bian Yu's people have completely belonged to 201. How could Fang Haochen give up such a good opportunity?

When Bian Yu sat opposite Fang Haochen, or when Bian Yu agreed to eat with Fang Haochen, he was ready to listen to Fang Haochen's chat from wave-particle duality to quantum mechanics, from random matrices to Hodge's conjecture Prepare.

However, Fang Haochen blinked his eyes at Bian Yu and said, "I had a dream last night."

"Oh?" Bian Yu didn't seem to expect Fang Haochen to talk to him about such a topic, such an "emotional" topic.

"I dreamed about you and me." Fang Haochen said. "I dreamed that the two of us were walking on a boundless ice field. We took a step forward and took a step in all directions at the same time. We turned around and saw us with our backs to us. "

Bian Yu smiled. He looked at Fang Haochen, as if he was looking at an innocent child drawing a rainbow with an oil pastel, and asked, "And then?"

Fang Haochen said: "Then snow fell in patches from the sky, blue snow, like nitrogen solidified at minus 209 degrees, you stretched out your hand to catch a snowflake and showed me. Only then did I see clearly that each snowflake was A 'string' that moves, vibrates, smells of milk and honey."

"I wanted to take the 'string' from your hand, but you refused. You asked me your name, and I wanted to answer, because I knew it, but I couldn't say it."

"At this time, countless eyes appeared in the sky. They have no eyelids, but they can blink. Those big and small eyes blink one by one, like the sky is breathing. You look at the sky and put the 'string' on my hand, said 'It's okay if you don't remember my name', and you disappeared into an eye in the sky, watching me until I woke up."

Fang Haochen paused after finishing speaking. He looked at Bian Yu, and suddenly felt a strange expectation in his heart. He had had such a strange dream before, but after talking to Yuan Youbing, Yuan Youbing was very worried: "Brother, you are like this, don't Go crazy one day."

Indeed, this is just a dream, what is he expecting?

But Bian Yu didn't say that he was crazy like Yuan Youbing did, nor did he dismiss it hastily and laugh it off. Instead, he put down the chopsticks in his hand and thought about Fang Haochen's far-fetched dream seriously. He said: "You At the end of time and space."

Fang Haochen nodded: "According to the content of the general theory of relativity, when an object with a small mass is at the balance point of several supermassive gravitational forces, it will indeed be like this."

"I've never seen a dream explained by theory." Fang Haochen said with a smile, his smile was full of praise and appreciation for Bian Yu.

"No, it's not just that." Bian Yu was not just chatting with Fang Haochen, he carefully recalled the dream described by Fang Haochen, and suddenly he looked at Fang Haochen and asked briefly, "Can you smoke here?"

Fang Haochen hesitated slightly, pointed to the "No Smoking" sign on the wall of the cafeteria, stood up, and said to Bian Yu, "Let's go out."

After saying that, the two of them packed up the food they hadn't eaten, left the cafeteria, wandered aimlessly, and walked to the side of a towering old tree.I heard that this tree existed before the establishment of 201. When 201 was established, the entire forest was cut down. Only this ancient tree was left. A doctor from the research institute said it was too precious and a pity to cut it down, so it stayed.

Now, beside this ancient tree, a concrete ping-pong table was set up in the logistics department. Seeing Fang Haochen coming, the little comrades who were still playing here hurriedly dispersed.Fang Haochen didn't say much, and put the rice bowl on the table.

Bian Yu lit a cigarette, and in the smoke, he seemed to be the only one.From the beginning to the end, Fang Haochen just watched him quietly, he didn't know how long he had been waiting for Bian Yu, whether the time was short or long, they seemed to have really come to the end of time, a moment is eternity, and eternity is also a moment.

After waiting for a long time, Bian Yu finally spoke.

"I still don't believe that 201's research on the unified field has ever been successful."

Fang Haochen replied: "It doesn't matter whether you believe it or not. From my point of view, I am more inclined to think that it was a success or a phased success, so the explosion will produce light, heat, and radiation results that we cannot understand at present."

"It doesn't have to be the success of the research on the unified field to produce such energy." Bian Yu said, "What if there was no explosion at that time? You only recognized that it was an explosion through long-distance light and heat. Bar?"

"You mean..."

"I said what if the light and heat generated at that time were actually 201's experiment, which accidentally triggered some kind of energy? This energy is like an eye in the sky. It has always existed, but no one can understand it and no one can use it. , because it is the 'water' for fish."

"It's not something that happened, but it existed." Fang Haochen muttered, and started pacing back and forth under the old tree, "A good idea, indeed a good idea!"

"only--"

"It's just how to verify such an idea?" Bian Yu said before Fang Haochen.

"Yes, to verify." Fang Haochen clenched his fist and asked, "Do you have any ideas?"

Bian Yu lowered his head and thought for a while: "Although I can't be sure, I can give it a try."

"Really?" Fang Haochen's eyes lit up.

Bian Yu said: "Since energy is conserved, and this energy has been excited and transformed, it is very likely that there are still traces left in the former position. If such traces can be observed, this question will become a few or is it There is no difficulty in solving dozens of advanced math problems."

Fang Haochen asked: "What equipment do you want? Or what kind of equipment?"

"Optical instruments and radiation monitoring instruments." Bian Yu said, "If possible, I would like to visit the old 201 base."

"This is a bit difficult." Fang Haochen said, "The current level of martial law in the old 201 base, let alone you, my level of confidentiality is not enough."

"It's fine if you can't go there." Bian Yu didn't care, "Let's do it first, and then release it when we have the results. Maybe the confidentiality level will be there."

Speaking of this, Bian Yu raised his head, exhaled a thin puff of smoke, and looked up at the crown of this towering ancient tree through the smoke like frosted glass.That feeling is amazing, as if this ancient tree connects the past with the present, wisdom and truth. On the other side of this tree is another vast world. On the butt of the cigarette held by Bian Yu’s fingertips , the glowing Mars that sometimes shines and sometimes goes out is the Olympian flame that Prometheus stole for mankind.

Bian Yu turned his head, Fang Haochen said with a smile: "Maybe one day, I will really give you a snowflake, a snowflake made of 'strings'."

"No, no need." There was an unexplainable impulse in Fang Haochen's heart. Fang Haochen knew too well that he would be so excited that he would not be able to sleep tonight. If Bian Yu's verification was successful, it would probably overturn the research direction of more than 201 years in [-] .

"I will study with you." Fang Haochen said, then he walked up to Bian Yu in two steps, and gave him a short but extremely sincere hug.

Bian Yu was taken aback by Fang Haochen's embrace like this. The person who was looking forward to the end of science and philosophy just now was filled with the scent of Fang Haochen's hair. He knew it was the scent of soap issued by 201, but This taste is like a stimulant, making Bian Yu's heart rumble.

"Bian Yu, it's really right to let you come!" Fang Haochen let go of Bian Yu, and said enthusiastically and eagerly, "Two hundred researchers can't catch up with you!"

The original little throbbing was replaced by a helpless smile, "It seems that I have gained a lot today." Bian Yu said.

"What else is there to gain?" Fang Haochen asked eagerly.

"A precious wood of 201 was discovered."

"what?"

Bian Yu smiled: "Director Fang, you didn't notice?"

Fang Haochen shook his head, but he changed the topic and said to Bian Yu with a smile: "Don't call me Director Fang."

"Then what shall I call you?"

"You can call me whatever you want." Fang Haochen was still too excited, "How do you call your friends?"

"Friend?" Bian Yu paused for a moment, then smiled slightly, "Then can I call you honey?"

Note:

String theory is a branch of theoretical physics. String theory holds that there are no particles, only strings move in space, and various particles are just different vibration modes of strings.All interactions that occur in nature, all matter and energy, can be explained by the splitting and combining of strings.
