Chapter 136 The Grandfather Paradox and Time Travel

Ye Zhen came to the Longjiang Pig's Knuckle Restaurant downstairs after get off work.

There were already people sitting in the shop.

After the boss saw Ye Zhen, he went back and forth so many times.

The boss also knows that Ye Zhen lives nearby.

The fast food here is just a neighborhood business.

"Beautiful boy, you got off work so early?" The boss wiped his sweat with the sweat towel on his shoulder.

Ye Zhen just replied: "Yes."

The boss knows that Ye Zhen is not the kind of person who likes to talk, "How is your recent work?"

Ye Zhen sat down and replied, "It's okay."

The boss already knows what Ye Zhen eats every time he comes over.

So Ye Zhen didn't say what he wanted. He just sat down and the boss would serve Ye Zhen the food.

Just like the old barber shop in your neighborhood that has been in business for more than ten years.

There was only a middle-aged and elderly couple running a shop inside.

You have been getting haircuts there since you were a child. As soon as you sit down, your aunt will know what kind of haircut you want.

Basically no communication is required.

Ye Zhen is like this now.

After eating, Ye Zhen bought a bottle of root beer and returned to his staff dormitory.

Because Ye Zhen discovered that this [extraordinary thinking] requires a lot of brain power, which requires sufficient sugar to supplement it.

What could be more convenient than soda with more sugar?
After all, the consumption of mental work is actually no less than that of physical work.

Ye Zhen wants to see where this spiritual realm will take him?

【Do you want to open a new spiritual realm? 】

Ye Zhen spent 100000 popularity points to open a new spiritual realm.

I don't know if it's because I'm used to it, or for some other reason.

Now that Ye Zhen has entered the spiritual realm, he no longer feels dizzy.

When Ye Zhen opened his eyes, he found himself standing at the door of a house.

The melodious sound of a violin came from inside the door.

Ye Zhen looked at the surrounding environment. This was a suburban place.

"It looks like a sparsely populated place." Ye Zhen didn't see the rest of the people.

But Ye Zhen looked at the house in front of him and saw that it was a typical house in European and American countries.

Through the window, Ye Zhen could see a man in the house playing the violin intoxicated with himself.

And there were lights and colorful decorations inside, as if there was some kind of party going on.

Wait until the man turns his head.

Even a calm person like Ye Zhen couldn't help but be slightly shocked.

Because this person's appearance often appears in textbooks.

He is Albert Einstein.

"It's actually Einstein." Ye Zhen knew that he had traveled to the last century.

Judging from Einstein's appearance, he was already 50 or [-] years old.

After a long time, Einstein put down his violin.

"Maybe this is just a fantasy." Einstein sat down and took a sip of wine and shook his head: "There is no such thing as time travel."

At this moment, Ye Zhen knocked on the door directly.

Einstein looked out the door in shock, and the wine glass in his hand fell to the ground involuntarily.

"Impossible!" But there was a look of great surprise on his face.

Einstein trotted directly to the door and opened the door.

Ye Zhen and Einstein met.

"How do you know this place?" Einstein looked at Ye Zhen, "Are you from the future?"

At this time, Ye Zhen had no idea what Einstein was talking about.

But strictly speaking, Ye Zhen does come from the future.

Ye Zhen hesitated for a moment and looked at the man in front of him who was probably the greatest scientist in human history.

Even Ye Zhen couldn't help but feel excited.

Einstein laughed and said: "As expected! As expected, come in quickly!"

"I knew time travel was absolutely possible!"

Ye Zhen looked at the banner pulled inside.

I saw a banner that read, "Welcome people from the future."

Ye Zhen remembered a rumor.

It is said that Einstein himself secretly disappeared for a day in his early years.

It is said that he went to a deserted place.

The contents of the experiment were kept secret, and only Einstein himself knew everything.

He said that if the experiment was successful, he would release it for everyone to see.

If it fails, it depends.

Ye Zhen suspected that this time was that experiment.

"Future people, when did you come from?" Einstein poured a glass of juice for Ye Zhen. "Have we humans really invented a time machine in the future?"

After that, Einstein pulled two chairs to Ye Zhen.

"Thank you." Ye Zhen took the juice and said, "How can you confirm that I am from the future?"

Einstein laughed and said: "Hahaha, I did an experiment just to see if there is such a thing as time travel."

Einstein and Ye Zhen explained.

"I wrote a letter without anyone around me, and this letter is for the future."

"I wrote in the letter the time, place and people attending this party."

"I want to invite people from the future to come and join my party."

"If someone really invents a time machine, after reading my letter, he will definitely go back in time and join my party."

"If no one comes, there are only three possibilities." Einstein looked at Ye Zhen.

Ye Zhen thought about it and realized that this was really a wonderful method.

If there is really a human being in the future who sees this letter.

There will definitely be curious people who will go back in time and want to meet Einstein.

Einstein's status in physics alone is enough to make people do this. "If no one comes, the first possibility is that time travel is impossible."

"This shows that the grandfather paradox is correct."

Why do so many people say time travel is impossible?

Here is a very classic example.

What if you invented a time machine in the future?

Then you take a time machine and go back to the past when your grandfather lived.

You killed your grandpa.

What could this lead to?

If your grandfather dies, there will be no father. Without your father, there will be no you.

Without you, there would be no time machine. Without a time machine, you would not be able to travel back to the past.

Not going back to the past means that your grandfather was not dead at all.

If grandpa is not dead, you will naturally be born, invent a time machine, and then go back to kill your grandpa.

This is a paradox, completely unexplainable.

So many scientists say that time travel comes first before the grandfather paradox.

Einstein was not surprised at all after hearing Ye Zhen's words.

Because if there is really time and space travel in the future, it means that people in the future have solved the grandfather paradox!

"The second possibility is that humans will become extinct in the future."

"They became extinct before a time machine could be invented."

"The third possibility is that traveling through time and space will affect history."

"It's possible they're afraid of changing something, so they won't come to your party."

Ye Zhen finished explaining these possibilities for Einstein.

Einstein laughed and said: "He is indeed a person from the future. I don't know what to call him sir."

Ye Zhen had thought about it before.

Is the spiritual realm cut out of a certain episode in history, or is it something similar to a brain in a vat?

Or maybe it's a real return to the historical timeline.

Previously, Ye Zhen traveled back to Tesla's childhood as a quantum creature.

And passed some information to the young Tesla, thus changing history to a certain extent.

Now Ye Zhen himself is not a quantum state existence, but a real person.

This can be known from the juice Ye Zhen just drank in his stomach.

Ye Zhen is real at this moment.

Ye Zhen doesn't know if being here will cause changes in the future.

Does it mean that this information cannot be disclosed? "Einstein saw Ye Zhen's hesitation and said, "I understand the impact of information on the future. "

Ye Zhen said casually: "Maybe it is possible that there is more than one universe."

"Every time we make a choice, a new universe is born."

"This universe is parallel to ours, but slightly different."

After hearing Ye Zhen's words, Einstein's eyes lit up: "Parallel universe? Interesting idea."

You must know that it was 1955 when the parallel universe theory was proposed.

That time has clearly not yet arrived.

"Is it possible that every time you travel changes the universe, giving birth to countless universes?"

Einstein fell into deep thought, "This can explain the grandfather paradox."

"In other words, is it possible that you come from another parallel universe?"

As the person who invented the theory of relativity, Einstein's understanding of space and time.

It can be said to be unique in history.

There were no more than two and a half people who could understand Einstein's theory of relativity at that time.

Then Einstein asked Ye Zhen many things about the future.

Einstein was deeply troubled because he discovered the mass-energy equation, which allowed mankind to create the atomic bomb.

It's possible that humanity will be destroyed because of him.

So Einstein blamed himself very much.

"Humanity in the future will not be destroyed by the invention of the atomic bomb."

"On the contrary, the emergence of this weapon has led to relative peace." Ye Zhen explained with a smile.

Einstein finally breathed a sigh of relief after hearing this.

"I'm really afraid that the entire human civilization will be destroyed because of me."

Einstein once said a very classic saying.

I don't know what weapons humans will use in World War III.

But the weapons for the fourth time are definitely stones and sticks.

Therefore, in his later years, Einstein was in a state of self-blame and guilt.

And often depressed.

Ye Zhen suddenly thought of something, "By the way, do you have any paper here?"

Einstein asked: "Yes, what do you want to do?"

Einstein found paper for Ye Zhen.

Ye Zhen wrote a letter directly and gave it to Einstein, "You give it to your descendants and find a person named Ye Zhen in the future and give the letter to him."

Einstein didn't understand why Ye Zhen did this, "Okay, Comrade Future Man, I promise you."

Ye Zhen tapped his teeth lightly and activated his special vision.

I saw the meridians on Einstein’s body.

Historically, Einstein passed away from an aortic aneurysm.

Ye Zhen said softly: "Stop smoking and drinking, exercise more, and eat less high-cholesterol foods."

After hearing Ye Zhen's reminder, Einstein seemed to have realized something.

"Thank you for your advice, sir."

How could someone as smart as Einstein not know that Ye Zhen was trying to save him?

If Ye Zhen is from the future, then he must know how he died.

The reminder given to him now is equivalent to reminding him how to survive.
