"In this day and age, it is almost impossible to unify gravity with electromagnetism."

At this moment, a voice from behind them caught their attention.

Albert Einstein turned his head to look behind him.

The person who spoke was a middle-aged and elderly man who looked to be in his fifties and sixties, dressed very decently and wearing a pair of sunglasses.

There is a very special temperament on his body, and he looks like a big capitalist at first glance.

None other than Tony Stark.

Tony walked over, "Hello, my name is Tony Stark. ”

"Albert Einstein." Einstein held out his hand to Tony.

Tony raised an eyebrow, but reached out to shake his hand.

"He's the scientist friend I told you about." Char said.

"I'm an engineer, to be exact." Stark said.

At this time, another Alicia named Tony also came to the tavern, but she was dressed very simply, and her long white hair hung down casually around her waist.

Einstein looked at her suspiciously, and then at Alicia, who was sitting next to Char.

"Are they twins?" Albert Einstein asked curiously.

"Sort of." Char said.

What is the meaning of counting, Einstein said in his heart.

He looked at the two Alicia curiously, it was not that he had never seen twins in his life, he knew that even twins could not be exactly the same, if you looked closely, you could still see the difference.

But these two twins are different, except for their clothes and hairstyles, they are almost identical, and even their temperament is the same.

"What's the lady's name?" Albert Einstein asked.

"Called...... Isabel. Char said.

Albert Einstein nodded, "Good name, Britannia used to have an empress named Isabel too." ”

Albert Einstein was now in Britannia, although he was a German.

But at the beginning of the war, he had been engaged in anti-war activities.

He was relatively famous, so he was persecuted by Germany, and the emperor tried every means to raid his apartment and collect evidence of his crimes.

But in the end, they didn't get it, so they attacked him from a reputation point of view, saying that he had a problem with his character.

There was really no way, so Einstein came to Britania with the help of his friends.

It was his first day in Britannia.

Tomorrow, he will join the Royal College of Britannia as an associate professor of physics.

The newcomer, Alicia, looked at the wine glasses placed on the table and smelled the tantalizing aroma of wine.

"Is this yours?" Alicia said, pointing to the wine glass in front of Char.

Char nodded.

Naturally, Alicia picked up his glass and shook it slightly, then took a sip.

Einstein watched all this, this glass of wine Char had just drunk, and he did not think that this "Isabel" did not know, because she had just asked.

So......

Einstein smiled, he looked at Char and teased, "Now, I'm sure you're over a hundred years old." ”

Char raised her eyebrows.

"Time flies." He sighed.

Char smiled.

Suddenly, Einstein seemed to remember something and looked at Tony.

"You just said that a unified field theory is impossible?"

"It's impossible in this era." Tony said quietly,

"Gravitational force is a macroscopic force that requires observations from the stars to obtain data, while electromagnetic force is a microscopic force.

In this era when human beings have not yet stepped out of the earth, it is almost impossible. ”

"I have a paper called General Relativity, but it hasn't been published yet, and it's about gravity. It's not been confirmed yet, but I think it's going to happen sooner or later. ”

"I learned the theory of general relativity before I was 12 years old." Tony began, "It's true. ”

Hearing this, Einstein frowned, "But I haven't released ...... yet"

"The gravitational field is the curvature of space-time, right?" Tony Road.

Einstein narrowed his eyes slightly, "You...... Peeked at my paper? ”

Tony smiled, "If I'm from the future...... Can you believe it? ”

"I don't believe it." Albert Einstein said.

"Of course, in your theory, space-time is irreversible." Tony muttered softly, "But the macrocosm may not work, the microcosm is different." ”

"The rules of physics and the rules of time in the quantum realm are completely different."

"Quantum realm?" Einstein frowned, "I've heard Planck mention it. ”

"He is the founder of quantum mechanics." Tony said.

"You mean, he started a new branch of physics?" Albert Einstein said.

Tony nodded, "It mainly studies the motion laws of microscopic particles, including the structure and properties of atoms, molecules, condensed matter, atomic nuclei and elementary particles. ”

"If you want to complete the unified field theory in the future, you can start with quantum mechanics and unify the simplest microscopic forces, electromagnetic forces, weak forces and strong forces.

Then look for the relationship between these forces and gravity. ”

"Suppose you really come from the future," Einstein whispered, shaking the wine in his hand slightly, "What you said was studied by later generations and succeeded in the direction, right?" ”

Tony fell silent, speechless.

"It's never been my style to start with a simple challenge." Albert Einstein said slowly, "I will never, and I don't need to, take away the scholarship that belongs to others." ”

"Even if you might waste decades of your time in the future?" Tony Road.

"That's me on that plane you're in." Einstein had an absolute confidence in his eyes, "I never thought that the future would be predestined." If you are really a time traveler, then the moment you come to this world, everything changes."

Tony stared at Einstein quietly, with a glimmer of light in his eyes, and whispered, "So you're Einstein." ”

"You haven't made it clear yet." Albert Einstein said with interest, "How do you travel through time?" ”。

"A very special technology." "It can shrink a person to a very, very small particle, even smaller than a subatom," Tony said.

Small enough to enter the quantum realm, and, having found the laws of the quantum realm, quantum fluctuations break the Planck scale and then trigger the German-style effect, realizing the time shuttle of a fixed time and an era. ”

After a pause, he added.

The "German Effect" is an experimental discovery in physics. The experimental results show that at the microscopic subatomic level, the microscopic particles of the quantum state with low temperature can transfer the temperature to the quantum microscopic particles with high temperature, which completely violates the well-known macroscopic physical laws and realizes a reversible phenomenon of temperature transfer. ”

The reversal of the "arrow of time". Albert Einstein whispered, "So in a sense, it's not that you pass through time, it's that time passes through you." ”

"That's right." Tony bowed.

After a pause, he smiled, "So, do you believe that I am from the future?" ”

"I only believe in the truth." Albert Einstein said.

He slowly got up from his seat and drank the wine from his glass.

He looked at Char, "How much is it?" ”

"It's the first to open today, so it's free." Char laughed.

Albert Einstein nodded and smiled, "Then I wish you a prosperous business." ”

"Are you leaving?" Char asked.

"I'd love to continue communicating with you, but I'm going to report from school." Einstein said as he looked at the clock hanging behind Char.

He looked at Tony, "I want to go back and think about it and make sure it's accurate." ”

"You're still here, aren't you?" Albert Einstein said.

"Of course." Tony nodded, though he didn't know if he would still find the tavern.

After all, where Char opens the tavern now depends on his mood.

"Well, it's a pleasure to meet you, Mr. Stark, and Mr. Char, and. Two ladies. ”

Saying goodbye to them, Einstein slowly left the tavern.

After pushing the door open, he paused at the door for a moment, looked up at the tavern's name, and kept it in his heart.

Then slowly walk down the block.

Although he was calm, he set off a tsunami in his heart that swept the land.

He couldn't confirm that what the man named Tony Stark said was false, but he couldn't be sure it was true.

Because in this era, the concept of quantum has just been proposed by Planck, and the real quantum mechanics still lacks many theories to support it.

However, he also has his own way to verify it, so what he wants to do most at the moment is to go to school and report to the school, and then hurry home to deduce the calculation.

If he succeeds, his theory of relativity may also be an epic revolution.

After years of environmental modification bills, the environment in Britannia's capital has changed a lot.

Although there is still that foul-smelling soot in the air, it is much better than when the environment is at its worst, when the smoke is thick and you can't see your fingers.

At that time, in the newspapers of the capital, it was common to see some examples of people walking directly into the Taylor River because of the thick fog, and some people even drove into the car and drowned in the river, not counting those who were sick because of the not very good air.

But fortunately, Einstein's next school is in the suburbs, and it was moved there when the air pollution in the imperial capital was at its worst, where there were a lot of greenery and good air, which was a suitable place for retirement.

The atmosphere of war in Europe, which was gradually fiery, apparently had not yet reached Britannia.

Although the country has lost the superior position of being isolated in another world, with West France in front of it and the Maria Mountains, it is still difficult to attack Britannia.

But apparently, Einstein was immersed in his own world at the moment, calculating the possibility and direction of time travel in his mind, completely forgetting whether he should find a taxi or take a tram.

Just walked forward silently with his head down, as if thinking about something.

By the time he came to his senses, he had already come to a completely unfamiliar street.

He had just arrived in Britannia, and the city was densely populated with similar features of various streets and houses.

So, after walking a few ways, Einstein found that he seemed to be lost.

He's a bit of an introvert, so he's not inclined to ask for directions, and after looking for a few directions, he finds that some people are moving in the same direction.

So he followed the men, and they passed through several streets to a very wide square.

He almost thought he was in the Vatican, because it really resembled the church.

The square is surrounded by two semi-curved corridors, each supported by tall stone pillars that support the top of the gallery, and on the top are many statues with different and lifelike figures.

The statue in the middle of the square is flanked by a beautiful fountain, which symbolizes the water of life that God has given to the faithful.

This is probably the Baal Cathedral in Britannia, where Einstein was recommended by his local friends when he came to Britannia, and it is a landmark building in the imperial capital.

Legend has it that more than 100 years ago, an angel descended into the world and inserted a holy sword into the high platform of this church.

Arthur the Great drew this holy sword and defeated the invasion of the West Francois Empire and the Western Empire, bringing decades of peace to Britannia and bringing Britannia to another level, officially becoming a world power.

The first thing Mordred did after coming to power was to correct Arthur's name, so in Britannia, his fame was very positive.

Although the holy sword is no longer on the high platform, those who have seen the angel have also erected a statue of this angel.

Einstein walked curiously through the square and lined up into the interior of the Baal Cathedral.

Almost at first glance, he saw the angel statue, a very regular pure white marble statue.

But from the first moment he saw the statue, Einstein knew it must be the work of a master.

The two large wings spread out to the sides, floating in the air, the eyes lowered, and there was a feeling of compassion for all beings.

She held the holy sword in her hand, bringing hope to the dark empire at that time, and slaying the evil spirits.

Albert Einstein gazed at her face, the bridge of her nose was high, her contours were soft, and her features were exquisite.

But

For some reason, the more Einstein looked at it, the more familiar it felt, as if he had seen it somewhere

Suddenly, the faces of the two twins he had seen in the tavern came to his mind.

His pupils constricted slightly

The face of this statue is almost identical to that of the two twins. (End of chapter)
