Chapter 402 Yuan Xiao's Theory of Relativity ([-])

That night, with the live broadcast on the Internet and the successive interpretations of the reports by the reporters, the entire physics community in the world boiled up.

The physics section of the microcircle world version is the place with the largest number of people.

It's a pity that Yuan Xiao was blocked by Weibo, he can't leave a message here.

But it does not affect other people's discussions.
-
The constant speed of light is Yuan Xiao's assumption. This has not been proved, which shows that Yuan Xiao's theory is flawed.
-
This is obviously contrary to Newtonian mechanics.
-
I didn't see the details upstairs. Teacher Yuan said that when the macro moves at a low speed, it conforms to 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 a positive solution, but the faster the object moves, the Newtonian laws of mechanics are obviously not practical, and then we enter the world of relativity.
-
It's still hard to understand, one event, different observation points, the results are different, this is not a hell.
-
What if the speed exceeds the speed of light? ——
What about the mathematical explanation?Is there any formula or equation.
-
Tangyuan is poisonous.
-
Our physics community has finally ushered in the spring breeze.
-
Let's take a look at tomorrow's public class, what Teacher Yuan has to say.

The National University Guest House, the leader of the Science and Technology Department of the Ministry of Education, satisified with food and wine, and left with satisfaction.

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

The rest were physicists and school teachers, all of whom were flushed from drinking.

Zhou Zhengyi's tongue was sticking out: "Mr. Yuan, your theory of relativity is really eye-opening and unheard of.

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

Yuan Xiao is very modest: "Actually, this is also the result of the development and accumulation of the physics world. I just saw it by chance and did a little research.

By the way, this was discovered by Einstein, I just released it. "

Low-key and low-key, Yuan Xiao still has to face.

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

It's a joke, if it is an impostor, if it is discovered by archeology in the future, I will definitely be whipped to death.

Zhou Zhengyi nodded: "Then I have to study its application carefully, Mr. Yuan, this time there is no problem with this theory, right?"

Don't be like Newton Mechanics, he flattered all the time, but Yuan Xiao himself stabbed a stick 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. Brother, let's take it easy."

Zhou Zhengyi understands that even if he claims to be an absolute supporter of the theory of relativity this time, he still has to hold back.

Froz sighed.

The electromagnetic equation was discovered by himself, but the conclusion he drew was wrong.

As a result, Yuan Xiao became famous.

However, such a result is acceptable.

At least the field of future physics also has its place.

He made a toast to Yuan Xiao, and he still had to thank the person in front of him.

The next day, the public class continued.

Yuan Xiao began to finish.

The theory of relativity is very complicated. If it is really told, the students will not understand it.

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

For the rest, theories need to be sorted out and published for research by people in the physics field.

"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 they change specifically is actually very simple.

That is time dilation and space contraction. "

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

Whether time really exists, no one can prove.

But everyone can really feel its existence.

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

The conclusion is that the passage of time slows down when in motion.

Yuan Xiao did another thought experiment here.

Suppose there is a photon clock. This so-called photon clock is exactly one second when a photon is shot from below, reaches the top and returns.

Then, if the photon clock is still, such a second can be easily obtained, and the photon has traveled 30 kilometers.

However, if the photon clock is moving at a uniform high speed, that is to say, there is an extra horizontal speed.

Then when a photon is shot from the bottom, the movement route of it reaching the top and returning is the way of presenting a broken line.

In other words, it has moved more than 30 kilometers here.

Then, if the speed of light is constant here, the time will slow down due to the increase of the distance traveled.

In other words, the photon clock in motion is not only one second long.

How much slower, Yuan Xiao quickly wrote out a formula.

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

Here Yuan Xiao pointed out that since the movement in daily life is 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 called 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, it can also be verified experimentally.

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

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

"Of course," he began to close, "someone must have asked what would happen if the speed exceeded the speed of light.

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

Otherwise, serious logic errors will occur.

For example, if someone pulls out a gun and shoots at you, normally we know that you shoot first and then get shot.

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

This is not in line with our everyday 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 step into 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 relativity.

Including the orbit of the first planet discussed by everyone earlier, there are corresponding explanations in my thesis.

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

The reason for the trajectory deviation is not the problem of Newton's law of mechanics, but the reason of the adaptive surface of Newton's mechanics.

The real cause is that the gravitational field around the star changes the path of light.

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

Yuan Xiao smiled and put down the microphone, which meant that the public class on the theory of relativity had ended perfectly.
