Create nuclear fusion at the start

Lincoln lengthened under the escort of armored vehicles, as well as a series of sedans. I left the airport and headed in the direction of the University of Berlin.

And all around, there are already people who rushed to hear the news. Everyone, holding a sign in their hands, saw Lincoln coming long, and roared with a tsunami:

“Li Hao! Li Hao!”

Li Hao sat in the car, smiled and waved to the outside to say hello. In fact, I wanted to open the window to say hello.

But Xu Bing, who has great experience in defense, stopped it, saying that opening the window means danger!

That’s just too dangerous. If there is a gunslinger hidden in the crowd, then a shot from the cold is a great disaster.

Li Hao is not a stubborn person, so he just waved and signaled to the people outside through a layer of bulletproof glass.

Amid the welcome of the mountains and tsunami along the way, Lincoln finally drove into the University of Berlin in Germany.

In college, it was solemn.

All the teachers and students put on school uniforms or master’s uniforms and stood on both sides of the road, sandwiched between the lanes to welcome.

Banners everywhere: Warmly welcome Li Hao’s visit to Germany.

Warmly welcome Li Hao to give a lecture at the University of Berlin.

Welcome to the University of Berlin.

Welcome to Deutschland.

“It’s much warmer than the welcome ceremony of the stick country. ”

Xu Bing smiled and muttered to himself: “Chief Engineer Li, it seems that Germany is sincerely pursuing scientific progress. ”

Li Hao nodded and didn’t say anything: “It’s here, get out of the car!”

“Yes!”

Xu Bing immediately opened the car door and walked down.

At this time, Lincoln lengthened and stopped in front of the door of the auditorium. At the door, hundreds of reporters frantically took pictures, filmed and recorded.

There was a ‘click’ and the door opened.

Countless reporters held their breath, ready to press the shutter button at any moment.

Finally, the young figure walked out and stood on the red carpet.

‘Click-click’

Suddenly, the flashing lights and the shutter sounded.

Sitting in a wheelchair, Starf was pushed over, smiled and said, “Please.” 、”

Li Haoli gave in: “Please.” ”

So, together, the two entered the auditorium from the red carpet…

Journalists gave way and filmed.

All the way, into the auditorium.

This time, Li Hao came to Germany, and his attitude was diametrically opposite. Completely different.

Without any dragging or ink, he walked directly to the auditorium. And from the moment Li Hao stood on the podium in the auditorium, the audience was already full. Everyone, all seated.

There was no prior communication. But this is the tacit understanding of scientific researchers.

In Bangguo, Li Hao will say that he wants to go to the toilet. Will say all kinds of excuses, just don’t speak.

But when I came to Germany, there was no politeness, no greetings. Straight to the point where the speech begins…

At this moment when Li Hao began. Hundreds of seats, all neatly placed.

All the scientists in Germany were present. Everyone sat down meticulously, their eyes locked on Li Hao on the stage. And most of them have already taken out their notebooks and pens, and are ready to take notes at any time.

Live to the world!

And this live broadcast also completely let people all over the world see what a real scientist should look like. There is no three-headed six-armed, usually more time, all I have is a notebook, a pen. That’s all.

Li Hao smiled at the audience and walked to the microphone:

“I’m Li Hao, I’m from China. Most of the people here here are scholars who study science, physics, or mathematical chemistry like me. We don’t have much nonsense, I’ll just get to it. ”

“This time, I’m going to talk about special relativity. Because last time, I already talked about General Relativity. However, the theory of relativity is an umbrella term. I believe that this is rarely in vain before this. Just heard, the theory of relativity. However, it is not clear what the theory of relativity is

As he spoke, the audience was silent. Everyone held their breath.

At the same time, all the world’s eyes are glued to the TV screen.

Scientists in various countries have gone crazy. The science students and teachers of the famous universities in various countries also stood in front of the TV excitedly at this time, holding their breath.

“In the narrow sense!”

On the TV, Li Hao’s voice was a little louder: “These two words mean that it is only applicable to the inertial frame of reference.” And it is different from the traditional view of time and space. It is a new theory of flat-value space-time. The first of these assumptions is the principle of special relativity and the principle of invariance of the speed of light!”

“The Principle of Special Relativity: All Laws of Physics. The laws of mechanics, electromagnetism, and other dynamics of interaction in addition to gravity. Valid in all inertial frames;

In other words. All the laws of physics, all equations except gravity, remain in the same form under the Lorentz transformation. Experiments conducted at different times give the same laws of physics, and this is the experimental basis of the principle of relativity that I am going to talk about…”

At the scene, everyone listened in silence.

Listen, journalists, politicians, and ordinary people gradually don’t understand.

Listen to it later.

Listen, some young scientists, or students, don’t understand. Began to doze off.

However, all over the world, at this moment, some elderly scientists suddenly widened their eyes.

There was some horror in his eyes.

Because they heard a new idea, a new system of physics.

It’s something they haven’t dabbled in at all.

Suddenly, an old German scientist at the scene stood up as if he was enchanted and exclaimed:

“I want to interrupt!”

‘Brush Brush Brush’

Everyone turned their heads.

And Li Hao stopped and looked at the old professor: “Please speak.” ”

The old professor gasped and said in a trembling voice, “You… What you mean is, suppose an object is infinitely close to the speed of light. So time on that object slows down? I would like to associate with that, if you put an hour hand on a substance that is infinitely close to the speed of light. So…… So as it approaches the speed of light infinitely, time slows down materially? Is this time traveling?”

‘Shhh

Everyone in the audience gasped.

At this moment, the dozing reporters and dozing politicians all woke up.

They don’t understand those theories.

But what this scientist said, they understood!

Time travel!

Time travel?

What an incredible thing this is, something that humans dare not dream of. Because of the countless conjectures and theories that have been carried out for a long time, time travel cannot exist. Because there is another famous one in it – the grandfather paradox.

Such a paradox lies here, like a mountain, and it simply cannot exist. But now, Li Hao said that in the theory of special relativity, time and space travel exists?

‘Hum’.

All over the world, all the scientists, all the viewers in front of the televisions, stood up in horror.

In general relativity, they don’t feel anything. Because those things have been studied a long time ago, although the core knowledge is kept secret, some of the general things are still known.

However, the special theory of relativity is completely a theory that is so terrifying that it refreshes everyone’s three views.

It’s horrible!

At this moment, everyone’s eyes were locked on Li Hao on the stage.

Everyone looked at him with bated breath.

Li Hao smiled, picked up a glass of ice Coke, and drank it under the eyes of the whole world.

00…….

‘Hiccup-‘ hiccups into the microphone without hesitation.

But no one cares.

Everyone was still staring at him, refusing to let go of the details of their expressions.

Li Hao looked at the professor and chuckled: “Answer you.” ”

With a solemn expression, Li Hao said in a deep voice:

According to the time dilation theory in the special theory of relativity, time and space shuttle, in a relative sense, exists. ”

“If we build an object that is infinitely fast, infinitely close to the speed of light. Let it move as fast as possible. Then as its speed changes, time changes… We look at the moving object from the perspective of a bystander, and assume that an hour has passed, and it has moved for an hour. It stopped, and time slowed down in the object. Perhaps, in the midst of this object, only half an hour has passed!”

“If we expand our thinking. An object built can sit in it by a person. Then this object begins to move infinitely close to the speed of light. Suppose that the person entering the object is as old as the observer standing outside, both of whom are twenty years old. The object starts moving. ”

“It moves at speeds closest to the speed of light. In the world of the observer, it has been in motion for fifty years without stopping. Fifty years have passed. ”

“The object stops, and in the midst of the object, the participants who enter the object… Possibly, it just feels like a moment has passed, a few seconds have passed, or a minute has passed. In the eyes of the participants, they were only in for a moment. But when he came out, the observer who was the same age as him became an old man of seventy. And he, time still stands still in that moment…”

This sums up what I am talking about here today: time dilation, length contraction, quality relationship, and mass-energy relationship. ”

And that, to sum up, is the special theory of relativity! It echoes the general theory of relativity. Collectively known as the Theory of Relativity!”

“……”

Quiet!

The whole world, at this moment, fell silent.

Time travel…

Time Dilation Theory!

At this moment, the whole world was shocked for a long time!_
