Three-Body Technology, Start Testing Water Drop Detector

Chapter 9 The Water Drop Answers!

Jia Lao said so.

Everyone is bright.

Yup.

It is certainly no accident that water droplets reflect electromagnetic waves 100%.

This shows that the makers know about electromagnetic waves, and their worlds use them extensively.

In order to make the water droplets invisible.

That's how the water droplets are made.

As for whether the manufacturer knows about the sound waves of air vibrations.

Nobody knows!

They've just fallen into a vicious circle of thinking.

It is thought that water droplets reflect electromagnetic waves 100%.

That electromagnetic wave is absolutely useless.

"Quick, get the electromagnetic wave transmitter ready."

In the plane, someone immediately began to set up an electromagnetic wave transmitter.

The distance is only one meter, as long as the water droplet can reflect back one ten millionth of the electromagnetic wave signal.

Their receiving devices are able to receive.

At the same time, it is proved that water droplets do not reflect electromagnetic waves 100%.

"Adjust the electromagnetic frequency, and send a 'hello' according to the Morse code." Jia Weiguo said.

Hello can be regarded as the idiom of Longguo to say hello internationally.

He and hello or hi mean the same thing.

It should be able to represent the friendly attitude of human beings.

The scientist manipulating the device nodded.

An electromagnetic code for 'hello' is too simple.

It will be done soon.

The sending device is aimed at the water drop in front.

Immediately press the launch button.

Electromagnetic waves are emitted at this distance.

There is no point other than experimentation.

"DiDi..." A beeping sound came from the device.

Indicates that the signal was sent out.

The receiving end is connected to a computer screen, which constantly refreshes the receiving information.

"How is it?" Everyone looked at the screen.

The receiver shook his head.

The speed of electromagnetic waves is the speed of light, and at such a short distance, the return signal should be received in an instant.

But from the computer screen.

The direction in which the signal is emitted is empty.

No water droplets are visible at all.

"At a distance of one meter, even one ten millionth of the electromagnetic signal is not reflected back. The electromagnetic wave in the true sense is invisible!"

Although the previous data.

Everyone already knows the result.

But when they saw it with their own eyes.

The shocking feeling is indescribable.

It's like a person putting on a piece of clothing and suddenly disappearing in front of you.

This piece of clothing can achieve visual stealth.

We all know that this kind of clothing is impossible.

but now.

An electromagnetic invisibility cloak did appear.

Putting on this invisibility cloak really makes electromagnetic waves blind.

"It's definitely alien technology, for sure!"

Even the voices of the scientists in the conference room changed.

Everyone is doing cutting-edge technology.

Even the Eagle Country.

It is absolutely impossible to make such an absolutely invisible material.

The only explanation is that it came from aliens!

Think Eagle Nation's B2 bomber.

A man's strongest stealth machine to date.

The RCS value in front of the radar is comparable to that of a bird.

This shows that it is not 100% stealth either.

Achieving this level of stealth effect is achieved through various efforts.

The first is that the unique aerodynamic shape and smooth appearance can refract most of the irradiated radar waves, so that radar waves cannot be reflected.

And its built-in bomb bay and landing gear retraction compartment are designed with serrated edges to ensure that they will not cause major damage to the stealth effect during use.

Secondly, the surface of the B2's fuselage is coated with a layer of radar absorbing material.

This absorbing coating can absorb radar waves, and the use of stealth aerodynamic shape and absorbing coating makes the reflectivity of radar waves irradiated on B2 extremely low.

Only in this way can such a degree of invisibility be achieved.

This is the limit that human beings can reach.

But this is not an order of magnitude compared to the water droplets in front of him.

If the way humans get information is not the eyes.

but electromagnetic waves.

In front of the water drop, everyone is blind.

Even if it's right in front of you, you can't see it at all.

Not even objects the size of a sesame grain can feel.

It reflects 100% of the electromagnetic waves you release.

...

"Continue to send signals." Jia Weiguo said.

"Repost?"

"Fa, maybe the alien civilization is now deciphering our signal, it will take a certain amount of time."

"OK."

drop by drop...

All are waiting.

The signal continued for half an hour.

All in like a stone sinking into the sea.

A drop of water is like a hidden stone.

There is no feedback.

The place was silent.

"Is it too complicated to encode the electromagnetic wave signal we launched?"

Someone in the room raised the possibility.

The signal they send all the time.

They are all sent according to the Blue Star Morse code.

The reason for sending Morse code.

I just think this is simple.

"Send another code?"

"Change what?"

"Just change the signal code of our Air Force. The code conversion software is already installed in the equipment."

The operator opens the coding software.

The software is clear and very easy to use.

Just enter the text you want to encode in the checkbox.

No one suggested that their Air Force signal encoding was more complicated than Morse encoding.

And Morse coding is the most widely used set of coding modes in the world.

If you say Morse code, the other party can't decipher it.

With Air Force signal coding, it is even more unlikely that there will be results.

"Hello."

The operator input is still these two words.

Through software, connect the device.

Electromagnetic waves coded for hello are sent towards the water droplets.

"Don't stop, keep going."

The operator sends basically every ten seconds.

drop by drop...

Once every ten seconds, the device keeps flashing.

One after another electromagnetic waves were sent out from the plane.

The receiving radar is also working.

Everyone is looking at the screen.

Did not receive any reply.

Not even a single shadow of the water droplets could be seen on the radar.

In the blink of an eye, the signal has been sent continuously for half an hour.

No feedback.

"Let's think of another way."

Obviously, using electromagnetic waves to communicate with aliens is not very good.

"Does anyone else have another way to get in touch with aliens?"

Everyone is trying to figure out a way.

I've tried sound waves and electromagnetic waves, but they don't work.

Scientists on the scene, the only thing they can think of now is that there is only light left.

The surface of the water droplets is as smooth as a mirror.

Anything standing next to it, the shadow will be clearly visible.

It's easy to imagine.

Contact with water droplets.

Could it be light?

When someone comes up with the word light.

Everyone is bright.

"Yeah, we're looking up from below and the droplets are glistening."

"Could it be that the aliens put water droplets at an altitude of 300 meters in order to tell us that we should use light to contact them?"

"That's right, it must be light!"

Whether it's the people in the helicopter.

Or the people in the conference room watching via live broadcast.

I feel like I'm heading in the right direction this time.

Electromagnetic waves, sound waves, light waves.

It is estimated that there will be no other way of transmitting information.

Since it is not an electromagnetic wave nor a sound wave.

Naturally there is only one last possibility.

"flashlight."

Humans can also transmit signals with light.

Optical fiber communication has been used for so many years.

But optical fiber communication is the communication between human beings themselves and themselves.

The decoding procedures of both parties are predetermined.

No one knows, whether aliens understand decoding.

Just try it.

Zeros and ones are represented by flashlights on and off.

The light of the flashlight shines on the water droplets.

It reflects almost 100% of the light back.

And it is a diffuse reflection.

Soon, a set of signals was sent.

This set of signals is very simple.

Morse code is also used.

The message delivered is: "Hello!"

...

On the Jinke Building.

There should be no less than thirty anchors gathered.

At the same time, in other places around, at least tens of thousands of people are watching the research on water droplets in the air in various ways.

"How far is this going?"

Questions abounded in the live room.

Since everyone can't hear the sound, they can only see some of their operations.

As for what the research is about, it's all guesswork.

"It should still be trying to find a way to get in touch with the water droplets."

"Sonic and electromagnetic waves have been tried, and now it's time to try light."

I have to say, there are gods like clouds in the live broadcast room.

No sound.

Just by their actions, you can tell what they want to do.

"If you want me to say, don't bother, drag it down forcibly, and dismantle the research.

Maybe, this probe was thrown here by aliens. "

"I don't know if any of you are paying attention to the Internet, foreign netizens are all blown up!"

"I also paid attention. They are all condemning us from the Dragon Kingdom, saying that we are not qualified to make decisions for the entire human race. This is irresponsible to human beings."

"I think, they just can't eat the grapes and say the grapes are sour."

"I'm afraid we'll get in touch with alien civilizations first."

...

Chen Feng's research center.

Watching the group of scientists outside keep trying to connect with the water droplets.

Chen Feng somewhat admired them.

They have used all the means of communication in nature.

If you don't answer again, it's too much to say.

"Proton, use Morse code to answer them."

Replying one sentence will not affect your plans.

And think about it, it may be more conducive to the planning.

"Okay master, what's the answer?"
