That night, the live broadcast on the Internet and the reporters' interpretation and reports one after another made the entire physics community in the world excited.

The Physics Section of the Micro Circle World Edition is the place with the largest number of people.

It's a pity that Yuan Xiao has been blocked by WeChat and he can't leave a message here.

But it does not affect other people's discussions.

--The speed of light is constant, which is Yuan Xiao's assumption. This has not been proven, which shows that Yuan Xiao's theory is flawed.

--This is obviously contrary to Newtonian mechanics.

--I didn’t see the details clearly above, but Teacher Yuan said that macroscopic low-speed motion complies with Newton’s laws of mechanics.

--Can it be understood that Newton's laws of mechanics are just a branch of the theory of relativity?

--This is the correct answer, but the faster the object moves, Newton's laws of mechanics are obviously impractical, and it enters the world of relativity.

--It's still hard to understand that for an event, if the observation point is different, the results obtained are different. This is not a ghost.

--What should I do if the speed exceeds the speed of light?

--What about mathematical explanation? Are there any formulas or equations?

--Tangyuan is poisonous.

--Our physics community has finally ushered in the spring breeze.

--Let’s take a look at what Teacher Yuan will say in tomorrow’s open class.

The leaders of the National University Guest House and the Ministry of Education and Science left with satisfaction after having a good meal.

It can be said that Yuan Xiao has lived up to the high expectations of his leaders this time.

The rest were physicists and school teachers, all of them drunk and blushing.

Zhou Zhengyi was tongue-tied: "Teacher Yuan, your theory of relativity is really eye-opening and has never been heard before.

It can actually include Newtonian mechanics, and time and space can change. No one has ever thought about such a problem."

Yuan Xiao was very modest: "Actually, this is also the result of the development and accumulation of the physics community. I just happened to see it and did a little research.

By the way, this was discovered by Einstein, I’m just posting it.”

Even if he is low-key and low-key, Yuan Xiao still needs to be proud.

Yuan Xiao had no intention of taking the theory of relativity discovered by Einstein as his own.

It’s a joke. If you pretend to be someone else, if archeology discovers it in the future, you will definitely be beaten to death.

Zhou Zhengyi nodded: "Then I will study its application carefully, Teacher Yuan, there is no problem with this theory this time."

Don't be like Newtonian mechanics, who praised it all the time, but Yuan Xiao himself stabbed him in the back.

Yuan Xiao comforted: "There is definitely no problem with the theory of relativity, but it doesn't mean that all problems can be solved. I'd better take it easy."

Zhou Zhengyi understood that this time even if he claims to be an absolute supporter of the theory of relativity, he must have some reservations.

Froze sighed.

I discovered the electromagnetic equations by myself, but the conclusion I drew was wrong.

As a result, Yuan Xiao became famous.

However, such a result can be considered acceptable.

At least the field of physics will have its own place in the future.

When he toasted to Yuan Xiao, he still wanted to thank the person in front of him.

The next day, the open class continued.

Yuan Xiao began to finish.

The theory of relativity is very complicated, and students would not understand it if it were actually explained.

Yuan Xiao actually made a lot of simplifications in the open class.

The rest still needs to be sorted out and published for people in the physics community to study.

"So, now we know that time and space are relative," Yuan Xiao held the microphone, "they will change due to changes in the state of motion.

So how exactly do they change? It actually boils down to something very simple.

That’s time dilation and space contraction.”

The first is time, which is actually a very wonderful thing.

Whether time really exists, no one can prove it.

But everyone can truly feel its existence.

Of course, Yuan Xiao is not discussing the existence of time here, but the change of time.

The conclusion is that when in motion, time passes slower.

Yuan Xiao did another thought experiment here.

Suppose there is a photon clock. This so-called photon clock means that when a photon is emitted from below, it takes exactly one second to reach the top and return.

So, if the photon clock is stationary, it can be easily concluded that the photon has traveled 300,000 kilometers in one second.

However, if this photon clock is moving at a uniform high speed, that is to say, there is an additional lateral speed.

Then when a photon is emitted from the bottom, its movement route when it reaches the top and returns is in the form of a polyline.

In other words, its travel distance here exceeds 300,000 kilometers.

So, if the speed of light is constant here, time will slow down because the distance traveled increases.

In other words, the moving photon clock does not only last for one second.

Yuan Xiao quickly wrote out a formula for how much slower it would be.

In this formula, the relationship between the time of the two photon clocks depends on the speed of movement.

Yuan Xiao pointed out here that since the movement in daily life is just a drop in the bucket compared to the speed of light, the time before and after is basically the same.

And when the speed gradually increases, the closer it is to the speed of light, the slower time will become.

This is the reason for time dilation.

Yuan Xiao calls this value the relativistic factor.

What was originally very complicated and difficult to understand, after such an explanation, most people can understand it.

And using the formula, experimental verification can also be carried out.

Immediately, Yuan Xiao also gave a mathematical explanation of space contraction.

So far, Yuan Xiao has finished explaining the overall theory of relativity.

"Of course," he began to finish, "someone will definitely ask what will happen if the speed exceeds the speed of light.

My personal opinion here is that the speed of light cannot be exceeded.

Otherwise serious logical errors will occur.

For example, if someone takes out a gun and shoots at you, normally we know that you will be shot first and then you will be shot.

But if the bullet speed exceeds the speed of light, what you will see is that the bullet is shot first and then the gun is fired.

This does not conform to our daily law of cause and effect.

Of course, this does not mean that in the vast universe, the speed of light is the speed limit.

As for the reason, I hope to work together with physicists around the world, including everyone who may enter the world of physics in the future, to research and explore.

The above is my public lecture on the theory of relativity, thank you for listening.

As for the rest of the theory, I will publish it in a formal paper on the theory of relativity.

Including the orbit of the first planet that was discussed by many people some time ago, there are corresponding explanations in my paper.

The result I want to say here is that there are no other planets near the first planet.

The reason why trajectory deviation occurs is not a problem with Newton's laws of mechanics, but the reason for the adaptation surface of Newton's mechanics.

What is actually caused is that the gravitational field around the star changes the path of the light.

Well, after the paper is released, I welcome physicists from all over the world to conduct research and demonstration."
