"Anti-gravity particles?"

Zhang Wenkai is no stranger to the word 'anti-gravity', and from the day he went to school to learn physics, many people would ask the teacher what anti-gravity is.

But the teacher can only give ambiguous answers.

Why?

Because antigravity simply doesn't exist.

We all know that there are four most basic forces in the world: gravitational force, electromagnetic force, strong force, weak force, and other forces that exist are only the non-manifestation of these four forces.

And gravity is not a fundamental force at all, so how can we talk about anti-gravity!

At most, it is the common name for gravitation, and it is still randomly arranged by people.

If you want to prove the existence of anti-gravity, you must first prove the existence of 'universal repulsion', and only when you prove that the universal repulsion force is the opposite of gravity, then anti-gravity is possible.

And what is the most important question, which is that antigravity is not even theoretical.

Faster-than-light or space jumps are right or wrong, at least there is a theory, and the only thing that anti-gravity has is a few words, and the word 'anti-gravity' is not even explicitly used.

What this means means that there will be no research results in this century, or even in the centuries to come.

"Cortana, anti-gravity doesn't exist, does it?" Zhang Wenkai asked with some disbelief, he didn't know if Cortana's home planet had developed a relevant theory.

"Uh-huh! Anti-gravity really doesn't exist. Cortana nodded generously and admitted the facts.

"Since it's not the anti-gravity principle, how does the metal ball fly." At this time, Zhang Wenkai was already dizzy.

Xiao Na stretched out her hands, gently rubbed her temples for Zhang Wenkai and said, "The anti-gravity I am talking about is not the anti-gravity in Mr.'s mouth, but the principle of rebounding gravity." ”

"The gravitational force generated on the planet is a manifestation of gravitational waves, and if you can bounce off this gravitational wave, you will naturally be able to fly."

"Gravitational waves!" Zhang Wenkai remembered the word, which he had seen in Einstein's theory before, and now confirmed that gravitational waves do exist.

Even if Xiao Na said so much, Zhang Wenkai still listened to it in a fog, this knowledge is not incomprehensible without Einstein's mind, he is not a genius, it is impossible to understand everything, but he doesn't care, this knowledge can not be understood, he only needs to have Xiao Na is enough.

However, some basic principles still need to be mastered, after all, it has been involved here, and it is necessary to do some mastery, so as to save the time when the time comes.

"And what about anti-gravity particles?"

He knows that from the perspective of the study of the earth, particles are the smallest material components that can exist in a free form, but at the current level, it is not possible to explore all the principles of particles, and there are still many gaps.

As for what the form of anti-gravity particles is, he is even more puzzled, after all, people know very little about this level of knowledge, and Zhang Wenkai is no exception, he is not a physicist.

It's not that Xiao Na doesn't explain Zhang Wenkai in detail about anti-gravity particles, but even if she explains, Zhang Wenkai must not understand, this technology has also been studied in her home planet for thousands of years, and I am afraid that no one can understand the principle of it.

But Xiao Na still plans to briefly talk about some properties and characteristics, so that Zhang Wenkai has a relatively intuitive impression.

"Anti-gravity particles are a little different from other particles, they are very stable, it is difficult to decay under normal conditions, and they have a very long lifespan."

"And it's neither hadron nor lepton, it's uncharged, it's capable of crossing the gravitational field."

"If you have to know the properties, you can think of it as a branch of dark matter."

"Dark matter?" Zhang Wenkai's pupils shrank to the size of a pin's nose in an instant, and he can say greedily that as long as he controls dark matter, he controls the world and even the universe, after all, dark matter represents 30% of the material content in the universe and occupies 95% of the space of the universe.

"It's really dark matter!" Zhang Wenkai was a little excited, which could not allow him not to be excited, but this was a matter of future development.

If it's really dark matter, he can now enter the universe, and what is still bouncing on the earth, just how interesting it is on the earth.

Xiao Na looked at Zhang Wenkai's excited appearance and pursed her lips, she really couldn't bear to hit Zhang Wenkai, if the mother planet really mastered the principle of dark matter, would the earth continue to develop so unharmed? You must know that the mother star has invaded more than 300 galaxies.

"This is only a small aspect of dark matter, which has many functions that have not even been developed on the parent planet." Cortana, Cortana pinched the tip of her little finger.

Zhang Wenkai sighed, just now he felt that he had become a god, and Xiao Na's words knocked him off the altar, he knew that he was already in an unstable mood just now.

"Hmmm! I know! Tell me about the metal ball in front of you! At this time, Zhang Wenkai's heart did not fluctuate at all.

Seeing Zhang Wenkai calm down so quickly, Xiao Na secretly said that he really deserved to be the man she valued.

Now Cortana also has a complete emotion, and even human emotions are more complex, she also has her emotional world, and there is only Zhang Wenkai in her world.

In a daze, another robot had already split the metal ball from the tiny metal stick, Zhang Wenkai didn't know the reason for this, he looked at Cortana.

"Sir, the metal spheres you see are made of niobium-titanium alloys, which belong to the second category of superconductors."

"And the small metal rod that was dismantled, and a large amount of anti-gravity particles were stored inside."

"When the anti-gravity particle comes into contact with electricity, it spins and bounces off the gravitational waves, which achieves the effect of flight."

Saying that, Xiao Na used a holographic projection to show Zhang Wenkai the general shape of anti-gravity particles, a bit like two fish, biting each other's tails, when there is no electricity, they will remain stationary, and when there is an electric current flowing, they will slowly rotate.

When it rotates into a sphere, it begins to bounce off gravity.

The general principle, Zhang Wenkai has understood, but there is still one point that is still in the question stage, why the metal ball moves back and forth in the air, is it the stepped force caused by the different strength of the rebound gravity, in order to achieve the purpose of moving?

"Why are they able to move?" Zhang Wenkai felt that he had to understand the principle of movement.

Cortana grinned and said with some pride, "The reason for the movement is also due to a material on Earth. (To be continued.) )
