Chapter 467: The Way to Reduce the Speed ​​of Light to Zero

Two different ways of refrigeration, won't try both.

Although it is cumbersome, it does not mean that it will consume a lot of his time.

The method of liquid helium refrigeration can be completely handed over to the intelligent core in the central computer that has not yet been programmed, and only needs him to provide the corresponding parameters and design drawings.

With the corresponding parameters and design drawings, combined with the intelligent equipment in the CNC factory, automatic processing can be completely achieved.

Moreover, the beryllium-iridium alloy mirror he made did not reduce the weight. With the thickness of the mirror, it is completely possible to drill holes on the back of the mirror to arrange pipes for the flow of liquid nitrogen.

At the same time, he can hand-fabricate the 'time-domain matter-wave lens system'.

The audience in the live broadcast room were very curious about the Korean won's preparations.

If the previous liquid helium cooling is still within the scope of everyone's cognition, what is the so-called "time domain matter wave lens system" of the second method.

In this regard, the barrage of inquiries quickly appeared in the live broadcast room.

[I know liquid helium refrigeration, but what is the latter?I didn't catch the name. 】

[Time domain matter wave lens system. 】

[? ? ?What is this stuff, new technology? 】

[It sounds very tall. 】

[It feels like a certain top theory in the physics world, but when I think that it is used for refrigeration, I can't face the name in an instant. 】

[Me too, it sounds like some kind of super technology in novels and movies, but when I think of this super technology being used to freeze popsicles, I can't bear to look directly at it. 】

[I remember the anchor just said that this thing can produce ultra-low temperatures of minus 250 degrees. Are your popsicles frozen at this temperature? _]

[A popsicle at minus 250 degrees, tsk tsk, this hardness is probably harder than steel, are you sure your teeth are that good? 】

[The anchor explains, what is this lens?Is there anything else to do besides freezing popsicles? 】

The barrage was full of questions, and the audience was puzzled. Even experts from various countries turned their attention.

Not to mention the general audience, even they have never heard of this name.

'Time Domain Matter Wave Lens System'.

This name, just like what the audience in the live broadcast room said, sounds like something from the physics world.

But just because it can create an ultra-low temperature environment of -256.15 degrees Celsius, we can know that this is not an ordinary technology.

In this regard, the experts squatting in the live broadcast room are also very interested.

Past live broadcasts have proved that sometimes the technology that the anchor does not pay much attention to has great value to human beings.

Maybe this new refrigeration method can be applied to other aspects.

Looking at the barrage on the virtual screen, Han Yuan smiled and said:

"'Time Domain Matter Wave Lens System' is something designed and manufactured based on the theory of quantum physics."

"In the field of quantum mechanics, everyone must know what the most famous experiment is."

Hearing this, a barrage of 'cats', 'Schrödinger's cat', 'be my cat' and the like floated up on the virtual screen.

Han Yuan smiled and said: "That's right, in the field of quantum mechanics, there is nothing more famous than the 'Cat that survived the dead'.

"It is a thought experiment proposed by the famous Austrian physicist 'Schrödinger'."

"It refers to keeping a cat in an airtight container containing a small amount of radium and cyanide. There is a chance that the radium will decay. If the radium decays, it will trigger the organ to break the bottle containing cyanide, and the cat will die; if The cat survives without the decay of radium."

"According to the theory of quantum mechanics, since radioactive radium is in the superposition of decay and non-decay, then the cat should be in the superposition of dead and alive cats."

"But there can't be creatures that are both dead and alive in this world."

"So if you want to know whether the cat is dead or alive, you have to open the container to know the result."

"And when the container is opened, the cat in the box will collapse into a unique state."

"It's either dead or alive."

"This is the so-called half-dead 'Schrödinger's cat'."

After a pause, Han Yuan continued: "The 'time domain matter wave lens system' is designed based on this theory."

"As everyone knows, matter waves in quantum mechanics are just like their name: matter that moves like waves."

"And in the field of quantum mechanics, everything we thought we knew turns out to be a little bit unstable after careful study."

"The closer you get to absolute zero, the weirder the behavior of a lot of matter."

"For example, liquid helium becomes 'superfluid' at extremely low temperatures, meaning it flows without any frictional resistance."

"At sufficiently low temperatures, some particles exhibit wave characteristics, somewhat similar to the wave-particle duality of light, but different."

"In this case, we can use an electrostatic 'lens' of cloudy matter called a 'quantum gas' and use it to focus matter waves and behave in a specific way."

"For example, conventional gases are composed of loose arrangements of discrete particles, and every breath you take is filled with countless discrete particles."

"However, quantum gases are not such predictable substances."

"In this case, the quantum gas would assume a puzzling state of matter."

"This puzzling fluctuating state is called a 'Bose-Einstein condensate.'"

"The 'Bose-Einstein condensate' is the basis of the time-domain matter-wave lens system."

"Everyone can imagine that you have a pair of myopia glasses in your hand, and the lens of this glasses is composed of 'Bose-Einstein condensate' gas."

"Therefore, its curvature can be tailored to the patient's eye to focus closer or further away."

"And what happens when you adjust the focus of the glasses to infinity?"

After briefly introducing the 'Time Domain Matter Wave Lens System' to the audience in the live broadcast room, Han Yuan asked a question to the audience in the live broadcast room.

However, the ordinary viewers in the live broadcast room who asked this question were stunned, and had no idea what was going on.

On the contrary, the pupils of the physicists squatting in the live broadcast room, especially the experts in quantum physics, were stimulated to shrink suddenly when they heard this question.

The anchor in front of him has already made it very clear. If they still can't react, they will be too ashamed of their knowledge.

The so-called 'time-domain matter-wave lens system' involves the ultra-low temperature field and the fundamentals of quantum mechanics.

In quantum physics known as optics, if a 'Bose-Einstein condensate' gas is used to form a lens.

This means that the 'Bose-Einstein condensate' gas that makes up the lens, the quantum gas, will confine all the particles passing through the lens together until they pass one at a time at an astonishingly slow speed.

In classical physics, the slower a particle moves, the cooler it will be.

So this quantum gas lens is "tuned" to temperature by careful excitation.

Tuning the particles is not the key point, but the key point is that this "tuning" can be aimed at all the particles passing through the "Bose-Einstein condensed matter" gas lens.

Soon, physicists from all over the world were breathing heavily.

In these short seconds, they thought a lot.

Since the 'Bose-Einstein condensate' gas lens can 'tune' all the particles.

What about light particles?

Remember that light is both a wave and a particle.

What would happen if light particles passed through such a lens?
Does the speed of light remain the same, or does it slow down?
Thinking of this, no one's heart didn't beat violently.

Although Newton's absolute space-time view is deeply rooted in the hearts of the people, even up to now most people insist on it.

But in fact, after Einstein proposed the theory of relativity, space-time is not absolute anymore, your time and mine may be different.

In relativity, the speed of light has an effect on time.

This is the content of special relativity research.

According to the time dilation effect of special relativity, the speed of an object's motion will affect the speed of its own time.

The faster the motion, the slower the time will pass.Until it is infinitely close to the speed of light, the time of the object is infinitely close to being static.

This means that if the so-called infinitely close to the speed of light spacecraft goes 100 light-years away, and then returns.About 200 years have passed on the earth, but the people in the spacecraft may not have passed a second, that is, the blink of an eye.

But if someone on earth observes this man in the spaceship, you will find that he has only blinked once in the past 200 years.

This is the relativity of time.

It's a theory that hasn't been proven yet.

But if the 'Bose-Einstein condensate' gas is used to make a super narrow and huge lens, and the focal point of this lens is defined as the cosmic lens.

So will the time in this lens slow down?
And what if there are people living in it?

Will human life expectancy be extended relatively?

After all, theoretically speaking, compared to the outside universe, the time inside this lens is already relatively independent due to the influence of the speed of light.

After all, for top physicists, it is an eternal topic to study whether the speed of light is constant.

At the beginning of the 21st century, Dr. Xie Alek of the Institute of Pure and Applied Mathematics in Brazil proposed a new method that may reduce the speed of light to zero.

In physics, the constant speed of light is relative.

That is to say, light can travel about 30 kilometers per second in a vacuum, which is constant.

But when light travels through a medium, its speed is slowed down.

For example, the speed of light in glass is about 20 km/s, which is equivalent to two-thirds of the speed of light in a vacuum.

The new method of Dr. Xie Alek is to use a phenomenon called "outlier".

This 'abnormal point' refers to light waves of two different modes. For example, when a plane light wave and a spherical light wave merge, the light will stop on the original track and be lost.

In the new study, the scientists propose to stop this loss by using a 'waveguide' with 'parity-time symmetry', thereby stopping the light waves.

The so-called waveguide is a physical structure, such as an optical fiber, which is one of the waveguides.

Optical fibers can be used to guide the movement of light waves.

And this waveguide, called 'parity-time symmetry', can prevent the loss of light at 'outliers'

So according to theory, waveguides can be used to adjust light, after all, light is also a wave.

In this way, guided by the waveguide and constrained by the anomaly, the light waves of the two different modes can precisely balance each other.

And if the 'parity-time symmetry' waveguide is designed just to the anomalous point, then when the light reaches the anomalous point and stops, the intensity of the light remains unchanged, and the light pulse stops completely.

Although this is still a theory at present, this theory is the same as the root behind the question raised by the man on the screen.

The speed of light can be changed, slowed down, or even stopped.

With this discovery, it doesn't matter at all that this so-called 'time-domain matter-wave lens system' can produce ultra-low temperatures, okay?

In the simulated space, a problem that Won did not know about himself brought great inspiration and shock to the experts outside the field.

In fact, he raised this question simply to explain why the 'time domain matter wave lens system' can lower the temperature.

As for the interaction between the speed of light and time, he didn't think about it at all.

Not to mention that this thing is a cutting-edge theory in human society, even if it is evaluated by the knowledge and information in his mind, it is also an advanced technology.

Whether it can be realized, he does not know, nor has he thought about it.

But it’s okay to try it, if it can really prove something, it will have a huge impact on the development and impact of human beings.

Of course, this is exactly what the Korean won has been hoping for since the live broadcast.

Since entering the electrical age, Won has realized a problem.

As long as his live broadcasts don't stop, one day the technology he broadcasts will surpass the real world.

The following electric propulsion-free engine, high-energy storage lithium-sulfur battery, and gallium lanthanide silicon solar thin-film power generation panels have confirmed this guess in the electrical age.

And he has been broadcasting live broadcasts with technology beyond the real world, will it make countries rely heavily on his live broadcasts, will it directly abolish the self-technical development of human civilization.

After all, top-notch technology can be learned from his live broadcast room. Is self-development still necessary?

If you rely too much on him, this may be a considerable problem for the technological development of human civilization itself.

Although the technology in his mind can allow human beings to rush out of the earth at a speed of [-] meters and go into the universe, this may not be a good thing.

Han Yuan thinks it is not advisable to overthrow the seedlings and sacrifice the potential of civilization.

So after realizing this problem, he has been subconsciously trying to solve this problem through words and controlling the advanced level of live broadcast technology in the following live broadcasts.

In fact, many times when solving certain problems, there are simpler solutions in the intermediate knowledge information in his mind.

But these simple methods for him are things that have not been completed in theory for the current human technology.

If these things are broadcast, I am afraid that the theory will be broken.

And what kind of impact such technology will have, Won doesn't know, and doesn't want to know.

So he has been controlling the technical level of the live broadcast to ensure that the technological skills produced by the live broadcast can solve his problems, which is also within the theoretical scope.

So far, the effect of this control is quite good.
