I weave fate in parallel time and space

The middle-aged man raised his head and looked at the decoration of the tavern. Although it was exquisite and well-maintained, it could still be seen that it had gone through the baptism of time.

There are some scratches on the floor, and many tables and chairs are obviously patinated and have a very beautiful sheen.

He didn't understand antiques, but if a knowledgeable person came to look at these wooden tables and chairs, they would be worth a lot of money.

"Your store looks like it's been open for a long time," the middle-aged man said, "but why does it seem so empty?"

"It was closed for a while not long ago. It is only now open, and there is no publicity." Shaar said.

The middle-aged man nodded. He actually noticed that no one came into this store. He wanted to find a quiet place to sit.

He looked around and wanted to sit down in a deserted and quiet corner, but Xia Ya spoke.

"You can sit over here."

The middle-aged man slowly raised his head and looked at the bar, while Xia Ya pointed to the position in front of the bar.

"The rest of the area has been painted with a layer of tung oil, but it hasn't dried yet."

The middle-aged man looked around and found that there was indeed some unnatural luster on these tables and chairs.

He nodded, walked to the bar and sat down. At the same time, he took out a piece of paper and fumbled for something on his body.

"Are you looking for a pen?"

The middle-aged man slowly raised his head and saw the owner of the tavern handing him a pen.

"Thank you."

He took the pen, and then he was immersed in writing formulas on the piece of paper, and at the same time he was doing many calculations in his mind. He did not communicate with Char, nor did he order, as if he was immersed in his own world.

And Xia Ya didn't bother him, she just silently mixed the wine and deliberately lowered her voice to the lowest level while mixing it.

After an unknown amount of time, the middle-aged man exhaled slowly and put the pen back into its holder. The piece of paper was filled with dense formulas, even on the back.

He raised his head and saw the boss behind the bar pushing a drink over to him.

"Try it, the latest new product, free trial. After mental exercise, it will be better to add some sugar."

The middle-aged man raised his head and looked at the clock hanging on the wall behind the boss. Half an hour had passed since he came in.

Only then did he remember that he didn't order. This was a tavern. Instead of buying a drink, he sat there for half an hour, which made him feel a little embarrassed.

He said apologetically, "Sorry, I was too immersed in my own world just now."

"It's okay, there's not a lot of people around now anyway, you can sit here until the store closes." Xia Ya said with a smile.

After a pause, Xia Ya looked at the list and asked curiously, "Are you a scientist?"

"Theoretical physicist," said the middle-aged man.

Xia Ya nodded, "My name is Xia Ya, can I ask your name?"

"Albert Einstein," Einstein said.

"Einstein." Xia Ya frowned and thought for a moment, "I seem to have seen this name somewhere."

After a pause, his eyes lit up, "You are the author of the special theory of relativity, right?"

During this period, Einstein had already published the special theory of relativity, and even the general theory of relativity was basically completed this year. If nothing else happens, next year should be the time when he releases the general theory of relativity.

Einstein looked at Char in surprise.

"I also have a scientist friend." Xia Ya said with a smile, "So I also read some scientific journals. After all, technology is the primary productive force."

"Go forward a few decades, and who would have thought that ships could still land on land."

“Not everyone is a Tesla.”

Einstein laughed.

"I study theoretical physics. It may take a long, long time before I can truly change the world."

"Tall buildings never appear in an instant, right?" Xia Ya said.

"You are very wise." Einstein nodded.

"I actually don't quite understand your theory of relativity." Xia Ya asked curiously, "How can the time be different?"

"Indeed, many people now cannot understand it." Einstein nodded, "Because most people's thinking has bound themselves to a very narrow area with their inherent cognition.

If you want to understand the theory of relativity, you need to change a concept. "

Einstein looked at him and said, "Time does not actually exist. It's just that people can't explain the decay of things and the aging of people, so they give it the name of time."

“I have always believed that time, matter, and space cannot be explained separately by abstract concepts.

Everything in this world, everything we see, including ourselves, is composed of countless particles.

The movement of these particles causes the decay of objects and the aging of people. All phenomena defined by humans as "time" are caused by the movement of particles.

And since it is "motion", it naturally has speed and slowness. When the particles on your body move fast, all the particles around you will slow down relative to you.

So from your perspective, time around you will slow down.
Of course, if you want to distinguish the difference with the naked eye, you may need to use the speed of light as the unit. "

Xia Ya nodded in understanding, "It sounds very complicated."

Einstein smiled and said, "This is like a high-speed steam train. When you stand at the front of the train and sit on the hot coals, you will feel that your days are like years; but when you are in bed with a beautiful woman, you It will feel like time flies."

Xia Ya raised his eyebrows, "Suddenly I understood."

"And the more beautiful the woman is and the better her figure is, the faster this time will be."

"Hahahahaha!!!" Einstein laughed heartily, "You have understood the essence of the theory of relativity."

At this time, Alicia walked out of the corridor leading to the castle, but she changed into more smart clothes. The style of the clothes was simple and soft, without lace or other cumbersome details. She was wearing an apron from the store.

Her long hair was simply tied into a ponytail, making her look youthful and energetic.

Even Einstein, who has always been in love with flowers, could not help but have a flash of surprise in his eyes when he saw Alicia.

"She is my wife, Alicia." Xiaya said.

Einstein nodded and joked, "It seems like time flies by for you."

Xia Ya nodded noncommittally, "More than 100 years have passed before I knew it."

Einstein smiled. He thought the tavern owner was very interesting, funny and very humble in his speech.

Even for knowledge that goes against common sense, I don’t rush to deny it, but try to accept it.

This is a quality that many people do not have. On the day his special theory of relativity was released, many colleagues criticized him as a liar.

Until now, there are still a group of people who do not believe in the existence of the theory of relativity.

He picked up the drink on one side and took a sip. He said it was wine, but in fact it was more of a drink. It was sweet and refreshing.

He had never had a drink like this, but he liked it, and as he said, he felt much better after taking in a little sugar.

"You will definitely have many guests here in the future." Einstein said.

"Thank you for your good advice." Xia Ya smiled.

"Is there any wine here?" Einstein asked.

"Of course, you are asking the right person. The wine I have here should be the best in the world." Xia Ya said confidently.Einstein smiled and disagreed. All the tavern owners said that their own wine was the best.

Charia turned around and walked to the wine cabinet on one side, took down a bottle of wine from the top, and opened the stopper with a wine screwdriver.

With the sound of "Peng", the rich aroma of wine slowly filled the tavern.

Einstein took a deep breath and inhaled the aroma of the wine into his nose. He narrowed his eyes and showed an intoxicated look on his face.

Then, he opened his eyes and said in disbelief, "Isn't this really made of some kind of industrial synthesis?"

"Of course not. Where can we find this kind of technology now?" Xia Ya said with a smile.

Einstein shrugged, "Who knows, the speed of scientific progress now is beyond even my ability to react."

Xia picked up four goblets from the bottom of the cabinet and placed them on the table, then took the bottle of wine and poured some into three of the glasses.

And one of them he pushed towards Einstein.

"Why four cups?" Einstein asked curiously. There were only three people here.

"I will have a friend come over later." Xia Ya said.

Einstein nodded, then eagerly picked up the goblet in front of him, shook it slightly, and took a sip.

He was interested in wine when he was very young and went to many places to drink wine as an adult.

After he published the special theory of relativity and became famous, he also attended many high-society banquets and drank wine collected by big capitalists and nobles.

But these wines are not as good as the wine in this tavern. In addition to the rich but not pungent fruit aroma, the intoxicating aftertaste is endless.

Especially after drinking this wine, Einstein felt extremely comfortable physically and mentally, and even had a lot of new inspirations in his mind.

He came back to his senses, looked at the wine in the glass, and said with emotion.

"You're right, this is indeed the best wine in the world."

Xia Ya smiled and asked curiously, "I think you can't see these moving particles, but how did you discover this phenomenon?"

"math."

"math?"

A mysterious smile appeared on Einstein's face, "Don't underestimate mathematics. Although it is counter-intuitive, the results it derives are extremely correct. Most of today's physics Everyone is also using mathematics to deduce various physical phenomena."

The facts are indeed what he said, such as Einstein's general theory of relativity.

General relativity is a theory that describes the gravitational interaction between matter.

It holds that the greater the mass (or gravity) of an object, the slower time will slow down, that is, the object's gravitational field will distort space-time.

This theory corrects the understanding of gravity in Newtonian mechanics and puts forward the view that "gravity is the result of the curvature of space and time."

But in this era where humans have not yet stepped out of the stars, it is almost impossible to verify this theory.

But in the future, people will confirm the correctness of this theory from all aspects through the observation of stars with large gravitational fields in the universe, as well as the flickering of some special substances.

In other words, Einstein alone used pure mathematics and did not rely on any tools to arrive at this theory in an almost prophetic way decades in advance.

“To be honest, after I derived the special and general theories of relativity, an idea came to my mind.

If this idea succeeds, my name in history may be even louder than Tesla’s! "

"Can you tell me something?" Xia Ya said.

"Of course." Einstein laughed, "After I finished writing the general theory of relativity, an idea popped into my head.

Since the universal gravitation can be mathematically derived a "universal formula".

What about electromagnetism?What about other physical phenomena?
Can we also use a unified "world equation" to directly connect them?

Use one equation to explain the whole world! "

Einstein's eyes shone with excitement, and he was looking forward to that future.

Xia Ya nodded, "Sounds very interesting."

He is a person from another time and space, so he is very clear about Einstein's research.

This "world equation" also has a name, called "unified field theory"

It refers to the unification of gravity and electromagnetic force.

In later generations, on the basis of unified field theory, there was a grand unified theory, weak force and strong force.

There are four fundamental forces in the world, the weak force, the strong force, the electromagnetic force and the gravitational force.

Grand Unification is all about using a theory to unite them together, using a single equation to explain the universe.

It is not a mysterious thing, it is like the periodic table of elements, which can make human beings understand the world better.

It is the most important foundation of many technologies.

Of course, the difficulty of unified field theory is much more difficult than that of the periodic table of elements.

Einstein's purpose in establishing a unified field theory was to unify his theory of gravity, the general theory of relativity, with Maxwell's electromagnetic theory.

If successful, the unified field theory will become Einstein's pinnacle work.

However, Einstein's progress was not smooth. Due to the limitation of computer technology, no experimental results could prove the relationship between gravity and current magnetic field.

Although Riemann, who established the theory of curved space in any dimension, also firmly believed that both the gravitational and electromagnetic forces could be proved to be unified by simple Riemannian geometric derivation.

But unfortunately, apart from these, there is no way in Einstein's mind to prove his idea.

At this time, quantum theory was booming, and a large number of excellent physicists were involved in it, and few people followed Einstein to study the unified field theory.

Gradually, benevolent reminders or sharp criticisms of Einstein and the unified field theory followed.

Among the critics was Einstein's friend and colleague Wolfgang Pauli, who famously said it.

"What God shreds, he doesn't want people to put together," he said.

Pauli used this sentence to imply that the unified field theory cannot succeed.

Building a unified field theory is not a feat that can be accomplished by one person.

After Einstein's death, dozens of the world's top scientists worked together and spent decades to establish a unified model of the three forces.They are strong force, weak force and electromagnetic force.

Even so, gravity is still not unified with these three forces, and they have no clue.

The difference between gravitation and the other three forces is that gravitation is a macroscopic force, which is the force of the existence of stars, while the other three forces are microscopic forces, which are the forces between atoms.

Microscopic worlds may still be observable, but stars are much harder to observe.

And Einstein alone wanted to unify the most difficult gravity with one of the forces.

In this era of limited technology, unifying the two is almost a miracle that cannot be accomplished by humans.

If he could complete it alone, it would not be an exaggeration to say that Einstein was called the true god of physics.

Einstein has been working at the Institute for Advanced Study in Princeton in his later years, and the unified field theory he has spent half his life researching has not been successful and has no followers.

This physicist who should have had more great creations finally died alone in 1955... (End of this chapter)
